How to check and solve the problem that the phone always shuts down and restarts automatically:

1. Check your phone's battery.

Check whether there is any problem with the quality of the mobile phone battery, such as whether the battery is bulging, aging, etc., and check whether the contact between the mobile phone and the battery is normal and whether there is any looseness.

2. Perform a security scan on your phone.

If the phone is planted with a Trojan horse or a virus, it is very likely that the phone will always turn off automatically. At this time, all you need to do is open the phone's security software to conduct a complete scan of the phone, and if Trojans and viruses are detected, they will be killed immediately.

3. Check the mobile phone software.

If the same software is installed in the phone, it is also very likely that the phone will always turn off automatically, because there may be conflicts between the software with the same function when running, resulting in the phone always shutting down automatically.

4. Mobile phone flashing problem.

Flashing the phone can get more permissions and functions to use the phone, but the flashing of the phone may also cause problems with the system of the phone, causing the phone to shut down automatically.

5. The battery is faulty.

You can take your phone to the nearest mobile phone repair site or mobile phone service center for testing to see if there is a problem with the battery itself, and if so, replace it with a new mobile phone battery. Replacing your phone's battery during the warranty period is free of charge.

6. There is a fault in the mobile phone.

If there is no fault in the mobile phone battery after the mobile phone repair station or the mobile phone service center, then the mobile phone repair station can be asked to test the mobile phone to see if it is a problem with the mobile phone, and if it is a mobile phone problem, repair the mobile phone. During the warranty period, the repair of the mobile phone is free of charge.

1. The boot line is abnormal: use an external power supply to supply power to the mobile phone, use the electric meter to detect whether the indication has changed, if there is no change, it is likely that the boot line is broken or the boot button is not in good contact.

2. The power supply circuit of the battery is abnormal: use the external interface to supply power to the mobile phone, see if it returns to normal when it is turned on, if it is normal, it is determined that the power supply circuit of the mobile phone is abnormal.

3. The IC of the mobile phone power supply is abnormal: test the test point of the peripheral circuit of the power supply IC according to the circuit schematic diagram to see whether the test value is normal.

4. The system clock and reset of the mobile phone are abnormal: you can use the dual total oscilloscope to detect the CPU power supply of the mobile phone to check whether the waveform in the reset is correct.

5. Problems with logic circuits: that is, faults in the circuit version of mobile phones, which can generally be solved by repair welding.

6. Software conflict: The installed software does not match the system of the mobile phone, which may also cause the mobile phone to fail to boot, you can connect the mobile phone to the computer to delete the program.

7. If it is a copycat mobile phone, then I estimate that it can't be turned on because the chip inside is burned, or some of the small parts inside are loose, but this situation will only appear if you drop it, the chip burns may be because you charge it for too long, and the chip is burned, if the battery is charged, it is these aspects, if it is a brand-name mobile phone, such as Nokia, Motorola. These situations are rare, unless it is artificial, if it is a brand-name smartphone, and there is no improper use, it is a software problem, it may be a system crash, or because of the poisoning of the mobile phone caused by the software damage, generally this can only go to the maintenance office, however, I think the biggest possibility is caused by static electricity, it is recommended that you do not open the blind repair, or go to the repair office!
