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.
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.

- Complete battery discharge and other related battery problems.
- Firmware update failures.
- Software problems.
- Virus attack.
- Mechanical damage to internal parts.
Battery completely discharged
Battery problems can be temporary or permanent, and they have different solutions:
Incorrect system update
From time to time, the Android OS firmware and its shell are updated, but glitches may occur during the process. Often, after installing a new version of the system, equipment turns into a non-working “brick”. However, do not rush to replace it with another model; this can be solved by rolling back to factory settings.

Viruses
Viruses are another popular reason for difficulties with Android technology. They arrive by downloading files and applications from unknown sources, and can seriously damage system data necessary for startup.
