Recently, Lenovo devices have been in great demand on the smartphone market, but despite this, their owners also sometimes have complaints about the quality of the device. For example, recently the spontaneous shutdown of the Lenovo K5 phone has been actively discussed.
On thematic forums you can meet many users who are trying to find out the reason for this behavior of their phone. When faced with a problem for the first time, you should not immediately contact specialists and complain about the quality of the device: this could be the operating system’s reaction to a single failure.
But if Lenovo K5 turns off by itself regularly, then it becomes almost impossible to use. In addition, such outages can signal large-scale disruptions in the operation of the phone as a whole.
When a smartphone owner begins to be seriously bothered by the frequent shutdown of a Lenovo phone, he either goes to the service center immediately, or tries to solve the problem himself and looks for information on how to do this on the Internet.
First of all, it is necessary to study in more detail the spontaneous shutdowns of the gadget and diagnose their cause. We will talk about this further.
Lenovo Mechanical Problems
The device may malfunction due to a mechanical problem such as a malfunctioning battery. More than a year ago, most cell phones had an opening back cover, but now the situation has changed.
Considering that Lenovo K5 has a non-separable case, it will not be possible to look at the battery, but the manufacturer has thought through this point: you can check what condition it is in using software. To get information about your device's battery, follow these steps:

Using the Engineering Menu
To enable the engineering menu, you must enter a specific USSD request in the window for dialing phone numbers (*#*#3646633#*#*). This menu also has a lot of extras. opportunities and you can familiarize yourself with them in a separate article.
And now we are interested in a special section - “Battery Log”, this is where you can find information about the operation of the battery: how worn it is and what voltage level it produces. The minimum input voltage is 3.7 V, the maximum is 4.2 V, it is in this voltage range that the battery operates without interruption.
How to fix the problem
If systematic shutdowns of the smartphone are caused by mechanical damage to microcircuits and other small elements, you will not be able to solve the problem yourself. If the defect is due to a faulty battery, it is enough to purchase a new one and install it.
In case of a software failure, moisture, or incorrect charging when using a non-original cable, the problem can be solved independently. The process must be carried out as carefully as possible and according to the instructions.

Damage to the smartphone circuit board
A Lenovo malfunction of this nature may be caused by a fall or impact of the device. If, after the user bends it strongly with his hands, the gadget turns off or freezes, then this is the problem.
Of course, only a specialist can answer accurately, although this solution is useful: in comments on forums, many users noted that it was after trying to bend the device that they found the cause of the failure.
Android turns off while playing
There are not only games, but also other resource-intensive applications that load the phone: prolonged viewing of YouTube or videos in the player, various programs with a graphics load, and more.
Have you noticed that the phone gets quite hot? As a result, a protection may be triggered that turns off the phone and prevents it from breaking due to thermal reasons.
Try to search the Internet for information about your phone model and find out whether it is characterized by such strong heating under load, or whether this is an isolated case. There is a possibility that you will have to contact the service.
In addition, during prolonged heating, the incorrect supply of energy from the battery to the device modules may begin, resulting in a failure that causes overheating. But we'll talk about the battery a little lower.

Full phone reset
Resetting your device to factory settings is generally good for your phone. Especially if you made a backup copy and understand that all data and settings will be erased from the phone. But often this is exactly what we need. The phone will look like it was just taken out of the box.
Games, applications, photos, videos - all of this will be deleted, so I warn you again so that you do not forget about the backup copy.
A factory reset can be very effective in improving performance, extending battery life, and more. There is a high probability that this can also solve the shutdown problem. But it’s worth trying only if the first two tips didn’t help. Resetting can be useful , but it is often a rather lengthy procedure if a backup is rare for you.

Overheat
The peculiarity of all Lenovo cell phones is that they have control over the temperature of the device. You can always use the built-in sensors to protect the microcircuits from melting when the processor heats up too high.
This is exactly the function that the device performs: Lenovo turns off to protect the parts. After turning off the power, the smartphone cools down for a while, then you can turn it on again.
How can you determine if overheating is causing shutdowns? Of course, it is possible for craftsmen, but it will cost money, in addition, it is advisable to work only with proven specialists, otherwise you may lose new parts or pay money in vain.
Another option is a special CPU Monitor application that can show how loaded the central processor is and what its real temperature is. You need to log into your Play Market account by entering the correct combination of numbers or letters in your password.
Here you can find the CPU Monitor program and download it to your phone. After launch, a window will appear with all the necessary information, you can always find out the necessary information, which is very useful. In the comments on 22 different Lenovo forums, this particular application was repeatedly recommended.
Experts often advise using the built-in proprietary security program that the FlyMe shell is equipped with. You need to open the shortcut from your desktop and simply click on the “Fix” button. Don’t forget to also clear the cache, which regularly gains volume: no matter what kind of smartphone you have - Lenovo, , Asus or another, regularly clearing the cache is mandatory.

In such a situation, you need to check the condition of the battery and then replace it with a new one if necessary.

Using a smartphone in everyday life, we constantly stay in touch with loved ones, friends, colleagues and other people, learn the latest news and share information. If the device suddenly turns off against the owner’s wishes, this can lead to delayed receipt of data, loss of time to turn it on, and the inability to quickly make a call or take a photo.
This problem devalues the joy of owning even the most modern smartphone.
Battery charge
The reasons don't end there. Why does my phone turn off by itself? Check the battery charge. Not the most common case, but one that occurs in practice. It is the low battery charge of the phone that causes the device to turn off.
This situation is quickly resolved. All you need to do is charge your phone and then turn it on. You will notice how the problem disappears by itself. From now on, just keep an eye on your battery charge. Then you won’t have any surprises with your phone. In any case, you will be prepared to disconnect the device.
Applications
There are several options here. The first is that you have little space left on your mobile. In this case, you just need to make room. Remove a few of the most unnecessary programs or games - and the problem will disappear by itself.
The third is the presence of malware. To correct the situation, you will have to find and eliminate the problematic utility. After this, you won’t have to wonder why the phone turns itself off and on (Samsung, Nokia or some other). After all, the problem will disappear. Its reappearance is possible when the gadget is again cluttered with programs.
Reason 1: Power button is pressed
Frequent use or excessive pressing of the power button will lead to failure over time. Usually the button is pressed in and makes a contact, which causes the phone to constantly turn on/off. A typical malfunction of the button is a weak or absent movement when pressed, as well as a reaction to pressing when pressed with force.
Solution 1: Repair the power button
If the problem is with the button, you need to repair it yourself or take it to a workshop.
Solution 2: replace or modify the cover
Often, a case without open buttons causes the power button to be pressed. The dense structure of the case puts pressure on the button, which leads to a problem. Therefore, if the problem does not occur when removing the phone from the case, then the case should be replaced or a hole for the button should be cut.
