The Lenovo battery runs out quickly. How to fix fast battery drain on Android

Modern mobile phones have long ceased to be just a means of communication, but have turned into a full-fledged portable computer. However, in addition to the great capabilities of these gadgets, many smartphone owners have begun to encounter a fairly common problem - rather rapid battery drain. The tendency of Lenovo K5 phones to quickly discharge began to be increasingly noticed by users of this brand.

This drawback is explained by the fact that the multifunctionality of phones entails increased demands on batteries, the resources of which may not always be enough to complete all tasks. Apart from this, there are many other different reasons that can cause your battery to drain quickly. Let's look at them in more detail.

What to do if your smartphone discharges quickly

There are many reasons why the battery is discharged in a matter of hours. Now we will look at the most basic of them and figure out how they can be eliminated.

Reason 1: Maximum brightness

Often, users do not hesitate to set the display brightness of their device to high. However, you need to take into account that the larger it is, the higher the battery consumption by the screen. An acceptable brightness level is 40-50%. In the latest versions of Android, you can adjust the brightness from the curtain.

Reason 2: Many wireless modules are activated

If the battery on your phone begins to discharge quickly, you may have turned on mobile Internet, Bluetooth, Wi-Fi and did not turn it off. These modules are capable of draining a decent amount of battery power in a short period of time. You can disable them through the “Settings”

your device or through a curtain that is pulled out with your finger from the top of the display.

Reason 3: Applications running in the background

Sometimes the culprit behind why an Android phone quickly begins to discharge are applications that run in the background and consume power. To find out which programs are running in the background:

After this, applications will stop running in the background, and the battery will drain more slowly in standby mode.

Reason 4: Charge displayed incorrectly

Incorrect calibration is a common reason why a new phone begins to discharge quickly. You need to calibrate the battery of your device, and to do this:

1. Drain the battery completely so that the device turns off.
2. Next, remove the battery for 10 minutes and insert it back.
3. Let your smartphone charge for 8 hours (this is important).
4. After this period of time has passed, you need to remove the smartphone from charging.
5. Then you need to remove the battery and wait 10 minutes to insert it back.
6. You can start the device, the battery is calibrated.

Reason 5: The power controller has failed

Rarely, but still, the power controller can break down and transmit incorrect readings to the system, thereby not using all the charge and charging the battery slowly. What to do? In this case, you need to take the smartphone to a service center to have the chip repaired or replaced.

Reason 6: Update and firmware

Often, it is after updating the device that the battery begins to drain quickly. The developers are making a mistake. In this case, you should roll back if possible. Unofficial firmware can also be poorly optimized and consume a lot of battery. Therefore, it is always better to use only stock firmware.

Reason 7: Viruses

Malicious applications are one of the reasons why your battery drains, as they run in the background and constantly consume power. To check your phone for threats you need to:

Reason 8: Battery wear

Over time, the battery begins to deteriorate, hold a charge less and become hot. If you have been using it for about 3 years, it is worth replacing the battery with a new one.

Reason 9: Imbalance

Some Samsung devices encountered this problem when the battery capacity was not enough for the installed hardware. In this case, you should use portable batteries - Power Bank.

• On the Internet you can often find advice to use applications to calibrate the battery, for example, Battery Calibration. In fact, it is absolutely useless. Some claim that it helped, but these are isolated cases, and most likely this was not even the reason.
• There is also a recommendation to use the Clean Master application to clean the device and optimize it. This makes no sense, since all these programs consume a lot of battery and load the device. They are suitable if you need to clear the device's memory, after which it is recommended to remove them.

Uninstall (pause) energy-intensive programs on Android and iOS

In many cases, the reason the phone battery drains quickly is due to applications actively running in the background and eating up battery power. To track them, go to “Settings” – “Device” – “Battery” or “Settings” – “Power” – “Battery Usage”.

View a list of applications actively using the system and the amount of charge they use. If an app you don't need is consuming too much power, then you might want to consider deleting it.

In Android 9, you'll be able to enable Background Restriction for some apps. For all apps, leave the Battery Optimization option turned on.

The main reasons why your phone battery drains quickly

Battery power can quickly drain for various reasons. Conventionally, they can be divided into software and hardware.

Backlight brightness too high

Relevant for any smartphone or tablet, even if it is equipped with an AMOLED display. You could increase it completely by accident. Some applications are also capable of this, including all sorts of launchers.

It has long been possible to reduce the brightness of the backlight directly in the notification panel. Many smartphones support adaptive (automatic) brightness control - it is turned on in “Settings”, in the “Screen” section. Please note that enabling this feature does not remove the user's right to manually adjust the brightness of the display backlight.

Unoptimized apps quickly drain even a new phone

Many users wonder why the phone began to discharge quickly after they installed some not-so-well-known programs. The fact is that not all developers competently optimize their creations. As a result, their applications not only regularly freeze, but also place excessive load on the processor. This can even happen in the background, which is easy to notice by the heating of the smartphone in the chipset area. Of course, as a result, the phone will discharge very quickly.

Some programs are designed in such a way that they are constantly doing something in the background. For example, the client of the social network Facebook collects a lot of information about the user, including his current location. This is why experienced smartphone owners disable this application if it cannot be removed.

Don't understand which program can negatively affect the battery charge? Then go to "Settings". Find the Battery section here. It shows exactly what resources energy is being spent on. Among other things, the names of applications that have consumed more than 1% of the charge are displayed here. If something doesn’t suit you, then click on the program you don’t like. In the window that opens, you can delete the application, or at least disable it.

Viruses

It can also consume a lot of power by sending various information about your actions to the creators’ server. At the same time, such applications hide well, masquerading, for example, as Google Services. Remove all programs whose names mean nothing to you. Real Google Services cannot be removed from a smartphone. If the corresponding button is available, then be sure to use it. And do not download programs from third-party resources; it is better to limit yourself to Google Play and the device manufacturer’s online store.

If you still download applications using the pirated method, then install an antivirus on your device. It can be free Dr.Web or paid Kaspersky. If you are already wondering why your phone is quickly draining, then run an antivirus scan - it is possible that it will find the culprit of the problem.

Unstable firmware version

Large companies try to check in full. But even they have misfires. And what can we say about small manufacturers whose staff consists of a dozen and a half programmers... In short, updating the operating system does not always lead to improved performance and expanded functionality. Sometimes, after receiving an update, the user realizes that from now on his smartphone is quickly discharged. This may be due to poor optimization, new pre-installed programs, and even introduced viruses. Suffice it to recall the DOOGEE BL7000, the basic firmware of which contains three viruses that actively consume energy. Using standard means, it was possible to get rid of only one thing by disabling the Voice Recorder application. To be fair, software updates in the case of this device have increased the battery life, somewhat muffling the effects of viruses.

Unfortunately, going back is often impossible. Because of this, we recommend that you do not update immediately after a new firmware version becomes available for download. Wait at least one week. Read the reviews. If everything is in order, then most likely no one will write reviews. And if problems arise, complaints will not keep you waiting.

What to do if your phone gets hot and drains quickly due to a battery problem

Let's move on to hardware faults. The easiest way is to blame the battery for rapid energy consumption. And it may indeed be the cause of the problem. Especially if several years have passed since the purchase of the smartphone. The fact is that any battery ages over time, losing its working capacity. Some batteries age faster, some more slowly.

Nothing can be done about the loss of capacity; it cannot be restored. However, no one forbids changing the battery by installing a completely new one. Unfortunately, modern smartphones increasingly have a non-removable back cover. Because of this, you will not be able to remove the battery yourself unless you have special tools. However, this can be done at the service center. Yes, you will have to pay for the work and the battery itself. But you will return to the original battery life!

Do not install a battery with a high capacity inside the smartphone. Buying one may be a waste of money. The fact is that the power controller is tailored to the capacity programmed by the creators of the device; it will resist receiving more energy. Of course, these words apply to most, but not all smartphones. But why risk your money?

Problems with the power controller - the phone charges quickly and discharges quickly

A rare case, but it can happen. If you regularly change network adapters, then you may well have come across a low-quality copy. It could produce too much current or too much voltage. In this regard, the power controller either fails or begins to transmit incorrect readings to the system. In the latter case, it may not use the entire battery capacity. Because of this, the user will immediately notice that now 100% of the charge is flowing away somehow too quickly.

In many cases, the power controller has to be repaired or replaced, which is done by many service centers. You can try to calibrate the battery with a special application (you can easily find a lot of options). However, this action rarely helps.

Our tips on how to extend your phone battery life

A variety of factors could affect energy consumption. For example, a telecom operator may have rebuilt its infrastructure near your place of work. The cell tower is now further away, which means more energy is spent searching for a signal. And there is virtually nothing to be done about it. But you can use only one data transfer standard on a long trip. The fact is that the most energy is wasted when switching from 3G to LTE and back. If you are driving in a car, this process will be repeated regularly. But it can be disabled in the operating system settings by activating only 3G communication for a while

. This is done as follows:

1. Go to "Settings";
2. Go to the “Connections” section (on some devices this step is skipped);
3. Go to the “Mobile networks” subsection;
4. Click on the “Network Mode” button;
5. Select “3G/2G (auto)”, or even “3G only” or “2G only”.

Do not forget that this should only be done on long trips (at least from one end of the city to the other). This advice will also be useful for those who do not need high data transfer speeds outdoors.

Disable those wireless modules

, which you do not use. If it practically does not consume energy, then the same cannot be said about Bluetooth. “Blue tooth” can be turned off if you use wireless headphones extremely rarely, and you don’t have a smart watch or fitness watch at all. Many people prefer to deactivate the GPS chip, because it also consumes decent amounts of electricity. Although it is easier to prohibit them from using unwanted applications, leaving this privilege only to map services and, perhaps, the browser.

Avoid live wallpapers

. Often they are the ones who devour energy the most. They also don't always turn out to be useful. It is possible that you downloaded a launcher that was not optimized or filled with advertising, and it is because of this that the phone is now quickly draining.

If nothing helps at all, then you will have to buy a new smartphone. Or get one. This accessory can be kept in your bag, on your desk, in your dresser at home, or anywhere. The convenience of an external battery is that you can charge your smartphone at any time. In 2021, such accessories were wildly popularized by the game Pokemon Go, which works in augmented reality and eats up the charge in just a couple of hours.

Summarizing

It is often extremely difficult to find out exactly why a smartphone began to discharge quickly. But we hope that our article pushed you to take the right action. Remember that high battery capacity does not mean that the device will work for a long time. The duration of operation from a full charge, in addition to the battery capacity, depends on the following factors:

• The technical process used to create the processor - the thinner it is, the lower the power consumption;
• Operating system optimization;
• Display technology - AMOLED definitely outperforms IPS;
• The design of the smartphone - the more difficult it is for the antennas to catch a connection, the more energy will be spent on it.

In a word, do not be surprised that the device will require regular connection of the charger, although inside it there is a battery as thick as the palm of an adult.

Modern experts have been able to identify several reasons why the battery on your phone quickly runs out. These include the discrepancy between the data declared by the manufacturer and the real data, the operation of background “invisible” applications, and some other options. It will be useful for every mobile phone owner to know about them.

When figuring out why your phone battery drains quickly, you should start the conversation with the most common and common causes of this problem.

1. False information about battery capacity from the manufacturer. It often happens that the device’s passport specifies one parameter, but in reality the phone has completely different capabilities – fewer. Then the user’s expectations are not met, and it begins to seem to him that the gadget is discharged too quickly. To avoid such a problem, you should check your phone before purchasing, using a charger-discharge device. The latter will show how long it will take for the battery of the selected product to be completely discharged. You need to check this data with that stated in the phone passport.
2. "Venerable age" of the device. The capacity of any battery decreases significantly over time
   . Its wear becomes especially noticeable after 24 months. If the main cause of the problem lies in the age of the battery, then the only correct solution is to purchase a new battery.
3. Active use of the phone in extreme heat or, conversely, in cold weather. Unfavorable conditions for modern gadgets include temperatures below +3 and above +27 degrees. Therefore, in cold weather it is better to use a headset, and in the scorching sun, do not leave the device in open areas.
4. Poor quality mobile connection. If the user is regularly in areas with unstable cellular communications (for example, outside the city), his smartphone will discharge much faster. Indeed, in such conditions, the device requires more energy for normal operation.
5. Frequently turning on/off/rebooting the mobile phone. Some users, wanting to keep their gadget charged, turn it off several times a day. This is a very common mistake that ultimately only makes the situation worse. The best solution would be to simply put the device into power saving mode.

Battery usage rules

Just a few years ago, when buying a new smartphone, sales consultants advised “rocking” the battery - completely discharging and charging it several times in a row.

Now this advice is absolutely useless, since new batteries such as Li-Pol and Li-Ion use other technologies that such “stress” only harms.

Below are tips for using your phone to help extend the life of your Android battery.

1. It is extremely undesirable to completely discharge the phone, as this leads to a reduction in its lifespan. This occurs due to chemical degradation.
2. You should charge the device as often as possible.
3. The best charger you can use is the original one. Even though most phones now have the same connectors, each charger has a slight difference in voltage.
4. Do not keep your phone charging in direct sunlight. Even such a minor factor will greatly affect the duration of the battery charge.

The battery heats up and discharges quickly

If the user notices that the phone is heating up at the same time and the battery is draining quickly, then the reason for this may be the active use of the device. For example, long continuous viewing of videos without recharging or similar conversations, long periods of playing a game, or simply long “walks” across the Internet.

The phone can also heat up and quickly discharge when transmitting data via Bluetooth, launching several programs at once, or using a non-original battery.

This also happens when the user is unable to work with a new battery. You must remember that immediately after purchasing the device, it must be continuously charged for 15 hours. In this case, you cannot first bring the charge of the new device to a state close to 0%. Otherwise, the battery may experience serious errors throughout the entire time you use the device.

The problem discussed even more often is observed in the case of old batteries that have exhausted all their cycles. You can check this reason by removing the battery from the device. If the entire phone heats up from it, it means that an urgent replacement of the damaged part is required.

If the heat comes from the front of the device, most likely the cause of the problem lies in the long continuous use of the touch screen or incorrect operation of the processor.

Android MediaServer process

This process scans the phone's memory (internal storage, external card) for the presence of various multimedia files (audio recordings, photos, video files, etc.). When working correctly, the Android MediaServer process should terminate its work after detecting the next file, but it happens that the process goes in cycles.

The reason for this phenomenon could be, for example, damage to the media file, which is why the scanning process does not complete. In turn, this causes the Lenovo m3 to drain its battery quickly.

Let's look at the main recommendations that will help avoid incorrect operation of Android MediaServer:

1. To avoid this problem, it is recommended to “Safely Remove” your phone after synchronizing it with your computer. Failure to follow this recommendation increases the risk of files becoming corrupted while they are being transferred to the phone, which will prevent Android MediaServer from scanning files correctly and will not stop working.
2. It would also be a good idea to use high-quality memory cards that have high reading speeds and do not cause failures during file transfer.
3. Make sure there are no incompletely downloaded files on your phone. If there are any, then it is best to remove them.
4. You can format memory storage devices. It is very important to copy all your data to another device before this process. Otherwise, all files will be deleted.
5. Special utilities that will forcefully close this process will help you cope with the endless work of MediaServer.

These recommendations will help optimize the performance of Lenovo smartphones and save extra battery power.

Android phone dies quickly

For Android mobile devices, the screen is the main energy consumer. Constantly using it at the maximum brightness level can quickly drain the battery and generally negatively affect its performance and condition.

There are other active energy consumers in Android gadgets. Among them, the following functions and capabilities should be highlighted:

• geolocation;
• Bluetooth;
• Mobile Internet;
• animated wallpaper;
• Wi-Fi.

If all of them are actively used, then even the most powerful battery will discharge faster.

Freezing

A serious test for each device is operation in “extreme” conditions for it, which include low air temperature. Many modern devices contain Li-Pol batteries, the performance of which is significantly deteriorated in cold conditions. It has been noticed that at low temperatures, about 30% of the battery capacity is lost, which is why Lenovo batteries discharge quite quickly in the cold.

Why does your iPhone battery drain quickly?

All of the above reasons for rapid battery drain are typical for Apple smartphones. The operation of applications and widgets in the background is becoming especially important.

Many of these add-ons for iPhones, after installation, independently activate the autorun function and begin to work continuously as long as the device is turned on or until the owner of the gadget decides to disable them. The more such applications, the faster the battery drains and the more the device slows down. For this reason, autoloading and autorun should be allowed only for rare important programs, for example, antiviruses, instant messengers.

It should be noted that another common reason for strong heating and battery discharge in such smartphones is water getting into the inside of the gadget or a strong shock to the battery. If something like this happens, you should contact the service center specialists for help. The user will be notified of a problem by a red indicator on the battery.

We should also talk about mobile viruses. Malware that attacks iPhones does not always operate openly. Sometimes their activity becomes noticeable only by debiting money from the account and increased energy consumption.

If the device begins to quickly shrink and heat up even in sleep mode, there are outgoing SMS and/or calls that the user did not make, or some system functions have stopped working, you need to urgently seek help from an antivirus.

How to deal with the problem that has arisen

To cope with a problem, you must first determine its main cause. If she received incorrect information from the manufacturer about the battery capacity, then she will only have to accept the existing indicators or change the phone.

Drastic measures will have to be taken in the case of a battery that does not work well due to its “venerable age.” It is almost impossible to revive him.

The use of adaptive backlight helps reduce screen battery consumption in Android devices. It will change depending on the external lighting. A convenient function is enabled in the settings. To do this, you just need to select “auto” in the brightness settings. It is also advisable to configure automatic sleep mode if the screen is not used, for example, for more than 30 seconds.

As for applications and programs running in the background, control over them should be entrusted to special utilities. They can, among other things, manage autoloading.

Stop apps from waking up your phone screen

On the other hand, if notifications are necessary, don't allow apps to turn on the screen when sending notifications.

Procedure:

1. Go to Settings.
2. Next is “Display”.
3. And turn off the Ambient Display option (this means that notifications will no longer wake up the screen).
4. On Android 8 and above, you can leave Ambient Display enabled, but disable the additional permission for notifications that allows them to turn on the screen.

Choosing a program to save energy

Today, users have many applications at their disposal that can help them save the battery power of their smartphone.

The most popular energy saving programs:

• The application will prevent background services from waking the phone from sleep mode. This is a simple and intuitive program that reduces device activity during the minutes when it is not in use by the owner. It has only a minimal impact on the overall operation of the operating system.
• DU Battery Saver. Regulates background processes, switches energy saving profiles and shows battery usage statistics. It independently suspends the activities of services that actively “devour” the smartphone’s energy, but have not been used by its owner for a long time.

Battery Doctor. Has the functions of the applications described above. Allows you to quickly clear the system cache and switches profiles on a schedule. In addition, the program helps to charge the smartphone correctly - it starts and ends the process at the most optimal time for the device.

The autonomy of a mobile device is one of the key factors that a person pays attention to when purchasing a new Android phone. Therefore, manufacturers pay special attention to the characteristics of the battery: built-in capacity, operating time in various modes, and so on.

However, for all the years that smartphones have existed, the most common question that comes up on specialized forums dedicated to mobile technologies is why an Android phone runs out of juice quickly.

As a rule, users blame the Android OS, considering its “gluttony” to be the main reason for a depleted battery.

In fact, the user’s phone quickly runs out of charge if he makes basic mistakes in operating his gadget. Therefore, the purpose of our article is to understand why the phone discharges quickly, and what can be done about it.

If your Android phone's battery drains quickly, the first common reason is the screen brightness being turned up to 100%. In this case, the display “eats” the main reserve of the energy cell’s capacity. In fact, for comfortable work with screen interfaces, 50% brightness is quite enough.

Solution

To adjust brightness, go to the “Display” menu in your smartphone settings. Use the slider bar to select the most comfortable setting for yourself. Another easy way to adjust screen brightness is to turn on adaptive brightness settings. After this, the screen brightness will automatically change depending on how much light hits a special sensor.

Pay attention to screen features such as auto-rotate and smart sleep (the screen does not go dark while a special sensor detects that you are looking at the display). If you are sure that you can do without these functions, feel free to disable them. Thus, you will reduce the load on the battery by 5-10%.

3G/4G, Wi-Fi, Bluetooth, GPRS - turning on but not using these modules for their intended purpose can be the key reason why the battery on an Android phone drains quickly. These components, to one degree or another, place a constant load on the battery, including at times when they are not directly involved.

One of the most power-hungry modules is the GPS sensor. Of course, if you find yourself in an unfamiliar city or area, its launch is necessary to determine the user’s location on the map as accurately as possible. Geolocation is also enabled when launching a taxi application, when the driver can find a passenger even without specifying an address.

However, if you are at home and your GPS is turned on, you will more than once ask in bewilderment the question of why your Android phone began to discharge quickly.

You will find more information about the geolocation module in our article How to set up GPS.

Solution

Everything here is extremely simple: if you don’t need to surf the Internet, send email, or upload important data to a file hosting service, turn off the network modules. Also make it a rule: at least once a day, check if your GPS navigation is running after using services related to it.

The phone is constantly searching for a network

If the phone has poor network reception, this can also affect the operating time. In search mode, the communication module operates with increased power and drains the battery quite quickly. To avoid this, turn on airplane mode when there is no network for a long time . For example, if you are traveling on a train and find yourself in a basement or other place with poor reception. When you leave it, turn off airplane mode and the battery will thank you.

A little humor at the end.

Reason 3. Mobile games at maximum settings

One of the common reasons why a new Android phone quickly runs out of power is constantly dealt with by fans of mobile toys who download gigabytes of new gaming applications from Google Play. But a mobile shooter with 3D graphics, and even at high settings, drains the battery charge to zero within an hour.

Of course, it all depends on the level of detail in the game. However, by tweaking settings such as shadow display, water quality, light refraction, and the number of shaders, you will load the battery more than the highest screen brightness settings.

Solution

If you want to save battery power, do not run the game for a long time, especially if you plan to surf the Internet for a long time afterwards. Also try lowering your graphics settings from ultra and high to medium. Of course, the realism of the display may be reduced, but you will significantly drain the battery.

There is a very interesting genre of games in which the emphasis is not on graphical bells and whistles, but on plot and riddles. You can evaluate and, perhaps, fall in love with such applications using our article Text quests for Android.

Reason 4: Applications are running in the background

What if everything is fine with the screen and modules, but the phone quickly discharges in standby mode. In this case, the source of the problem is applications that are running in the background without the user's knowledge. For example, Google services and social networks constantly send data about the user’s location, call and SMS activity, and so on to the developer’s servers.

Solution

Check which applications are eating up your battery power. For this:

• Go to the settings menu
• Click on "Battery"
• In the list of processes that appears, find applications that use the battery
• Click the Force Stop command

Carefully study the entire list of utilities, due to which the phone discharges very quickly - in this case, the indicator shows a load of more than 1% of the battery charge. If you find an application that you haven’t used for a long time, it’s easier to delete it, thereby relieving some of the load on your smartphone’s battery.

Turn on power saving mode if the charge level is rapidly decreasing

For Android 5.0 and above, this feature helps maximize battery life and extend the last few minutes. Animations are reduced and most background synchronization and location services are stopped. You can activate the saving mode in “Settings” - “Power”.

Activate power saving mode

On Android 7 and above, you can optionally set the battery saver mode to automatically turn on when there is 5% or 15% of battery remaining.

Some phones, such as the Samsung Galaxy, also have an "Extreme Power Saving Mode" that disables all unnecessary apps. And only mail, watches, SMS and calls remain active.

Reason 5: Viruses on your smartphone

The phone quickly runs out of power due to malware that gets into the gadget if the user installs applications from untrusted sources, or ignores browser security warnings when visiting suspicious sites.

By the way, many dangerous applications are cleverly disguised as Google system applications. It's very easy to calculate them. System utilities cannot be removed - only forced to stop. If you find a “Uninstall” button under a supposedly built-in application, it is a definite pest.

Solution

To reduce the risk of dangerous viruses getting onto your smartphone, install applications only from trusted sources: from the Google Play page or the official website of the developer.

If you spend a lot of time on the Internet on your mobile phone, install reliable protection on your gadget. You can choose the most convenient antivirus program for yourself using our article The best antivirus program for Android.

After installing the security application, scan the entire smartphone, right down to the memory card. It is possible that the reason why the phone is discharged may be hidden on the external SD.

Ways to solve the problem

How to solve problems depends on their source. Therefore, you must first determine the cause of the abnormal operation of the battery, then you can begin to troubleshoot the problem.

If a manufacturing defect is discovered (or suspected), you must take the gadget to a service workshop (preferably, the manufacturer’s official service center, if available). Specialists will give an opinion with which you can claim that the manufacturer fulfills its warranty obligations. If the warranty period has expired, the service department will repair the phone, but at the expense of the owner.

If it turns out that the battery is worn out, then the only way is to replace it. Restoration tips that can be found on the Internet are, at a minimum, useless, and at maximum, fire and explosion hazards. Extinguishing a lithium-ion battery fire is very difficult and ineffective. To avoid deep self-discharge, it is necessary to periodically monitor the condition of an unused battery and, if necessary, recharge it.

A burning lithium-ion cell is difficult to extinguish.

You can restore a lost calibration in a simple way. You need to let the battery discharge to a conditionally zero level before turning off the smartphone. Then charge it to full. For reliability, you can carry out the procedure several times. You can also restore calibration using special applications.

If the problem is with the charger, the adapter must be replaced. It is useful to do this right away - when trying to localize a fault. You can take a known-good charger from another phone and try charging your gadget . If everything is OK, then the problem is in the adapter, and it must be urgently replaced while the battery is alive.

To avoid infection with viruses, you must avoid visiting dubious sites, do not download or open dubious sites. But if the virus is already on the phone, you need to use anti-virus programs (there are many of them, you can choose the most convenient and effective one). Sometimes resetting your phone to factory settings helps.

If abnormal battery behavior is noticed immediately after installing custom software, you must return the factory firmware. To do this, you need to contact a service workshop.

Basic rules for properly charging a smartphone

To extend battery life, it is important to follow simple but effective charging rules:

1. Do not allow the battery to be completely discharged too often.
2. Make sure the battery charge level remains above 20%.
3. Do not leave a charged smartphone connected to the network for a long time - this can also cause the battery to drain quickly.
4. Perform maintenance on the battery once every two weeks. Bring the charge to zero and charge to the maximum value.

The fifth reason why the battery in the phone began to run out - informers

Android has immediate access to email, but this service has a pretty big battery appetite.

This is not the case with Gmail, which is quite well optimized and doesn't even show up in the battery stats.

But the weather forecast, widgets, calendars, organizers, etc. it's a different matter. You don't need to constantly check, for example, the weather to make sure nothing has changed.

These informers often access the network and it is advisable to put them in data collection mode at a specified time.

Poor optimization

This point concerns phone manufacturers who did not want to work hard enough on the operating time of their devices. This is a purely software problem that is also related to the firmware. But there are some nuances here:

• Manufacturers often install the same software on different models.
• Charge control is very poorly implemented at the software level.
• There is no adaptation for more milliamps.

These are the main elements of poor optimization that negatively impact battery life. Manufacturers need to think carefully about why the battery runs out quickly on Android and take appropriate measures.

Which phones have problems with fast charging and discharging?

The problem can occur on any phone. More precisely, in many cases it occurs in the battery, and all batteries are produced using almost the same technologies - Li-Ion and Li-Po. Therefore, even the most advanced smartphone cannot exclude all situations in which the battery behaves abnormally.

Lithium-ion and lithium-polymer batteries.

If you now have a powerful phone that has a quad-core processor, three gigabytes of RAM, a high-quality display and a powerful speaker, then it is not surprising that they consume more power. If poor optimization is added, the battery can drain right before your eyes. What should you pay attention to technically when it comes to why the battery runs out quickly on Android?

• CPU. The clock speed and number of cores play a role here. Android phones do not have coprocessors, which are characterized by increased energy saving. This also negatively impacts battery life.
• Display. This is another reason why the battery on Android runs out very quickly. This is especially true for bright displays with large resolution and diagonal.
• Number of SIM cards. Many modern phones on this operating system have two SIM cards. If they work in parallel, this also negatively affects battery life. This is a very important point that explains why the battery runs out quickly on an Android phone.

This is what technically can drain the battery. Naturally, that's not all. But these points are basic. Be prepared for your phone to drain quickly if you buy a flagship model.

Incorrect use

This is also a pretty good reason. And for Android phones it is very relevant. The fact is that the system itself is built in such a way that applications are constantly running inside it. Even those that were closed. This system consumes a lot of battery. This is why the battery drains quickly on Android. Samsung is one of those companies that has been particularly criticized for this. Actually, for a reason. But if you use your phone correctly, the likelihood of losing it by the end of the day will significantly decrease. So what should you do?

• Turn off wireless and navigation functions.
• Reduce the brightness to minimum or at least turn on auto mode.
• Constantly close programs open in the background.
• Turn off mobile internet.
• Turn off automatic updates.

If you follow these tips, then you will not have the question “Why does the Android battery run out quickly on your tablet.” This also applies to the phone, like any other device running this operating system.

Automatic screen brightness adjustment

Maximum illumination is generally the number one enemy of the battery. It's nice to look at a colorful picture, but you have to pay for it with battery power.

We noticed how in the summer the phone sometimes dies very quickly. This is not only because we often take it out to take pictures of something. Automatic adjustment is also to blame. We simply don’t notice how in the bright sun it is always at 100% brightness . Indoors, 70-80% is usually enough and this difference is enough to quickly drain the battery.

Technical difficulites

Naturally, the reason for the rapid discharge of the phone can also be its breakdown. Under no circumstances should it be excluded. What can happen to the device that problems occur when using it?

• Battery capacity has decreased.
• There are problems with the charge controller.
• Problems occur when charging the phone.

These are the main reasons why the phone dies. They concern those people who have already used their device for some time. After all, such problems most often happen over time. However, no one canceled the marriage.

Troubleshooting hardware problems

Now let's touch on the topic of solutions to hardware problems.

Battery calibration using Google methods

We bring to your attention the battery calibration method proposed by Google. In some cases, it helps to normalize the behavior of the battery and power controller, which has begun to incorrectly determine the capacity.

1. Connect a completely discharged mobile phone to the power supply and charge it with it turned on for at least eight hours.
2. Unplug it, turn it off and charge it for another hour.
3. Disconnect the device, start it, use it for one or two minutes.
4. Turn it off and plug it back in for an hour.

The method looks strange, but it allows you to reset the controller statistics and adjust the real capacity to the software algorithms for calculating it.

Use only original charging components

This is important, since some devices with fast charging do not accept connection to third-party power supplies well. Also, too much power, for which the components are not designed for, can harm the battery, and it will begin to run out faster.

We have described the most important methods. Not all of them will be possible to accomplish, but the purpose of this article was also to explain to you what most affects the discharge, and you, knowing the reasons, could independently develop an energy-efficient and comfortable profile for working with the device.

conclusions

What conclusions can be drawn from this article? You need to carefully look at the following characteristics of the phone:

• Performance (processor, RAM).
• Battery capacity.
• Screen.

The battery life depends on them. As for the software part, you should pay attention to:

• Android version. The higher it is, the longer the phone will work.
• The presence of interface add-ons from Android always consumes less battery than interfaces from manufacturers.

If you pay attention to these points when buying an Android smartphone, its battery life will be much longer. You will be able to stay in touch with your loved ones for a longer period of time.
