Hello! The total automatic shutdown of the mobile phone can be repaired from the following aspects:

1 Check your phone's battery.

Checking the mobile phone battery is the first thing to do when the mobile phone always shuts down automatically, and the inspection of the mobile phone battery here is divided into two steps: 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 the battery 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 of your phone.

I hope my answer is helpful to you and I wish you a happy life!

1.The first situation is easier to do: it is a crash caused by the RAM memory overflow when you are playing games or running software, or the so-called "overcharge phenomenon" of Zheng Yan when the mobile phone has been charged continuously for more than 12 hours.

You can remove the battery board, let it stand for 1 minute, and then replace the battery to see if it can be turned on and if it is normal. Or if you shout that Yinguo has two batteries, you can try to change one. My phone has encountered a similar situation several times, a common problem with Android phones, and the specific reason is unknown.

2.The mobile phone cannot be turned on due to external damage, so it is recommended to go to the maintenance office for maintenance at this time.

Don't go to the repair point to repair at every turn, the owner of the repair shop will always give you all kinds of reasons to make you pay, and learning to troubleshoot the problem yourself is the king!

The computer cover is self-liquid, and the shutdown has nothing to do with the installation of the router.

The automatic shutdown of the computer is due to the following reasons: 1. The voltage is low, and the computer will know that the shutdown is lower than the working voltage of the computer, and the computer will have failures such as frequent shutdown and restart.

2. Shutdown caused by poor heat dissipation in hardware.

3. Shutdown caused by too much system virus and system junk.

1. The Lingjing protection circuit in the lithium battery is overly sensitive, so the current will be powered off as soon as it is large.

2. The battery itself has aged.

3. There is dirt in the metal sheet at the contact point of the battery, resulting in poor contact of the power supply.

4. The joint between the battery and the mobile phone is easy to loosen.

5. If after the inspection, it is found that the first two problems are solved, then it must be sent to a special repair shop for repair. If the latter two problems are caused by the oxidation of the dirty metal sheet of the battery, the situation will be improved as long as it is wiped clean with a glue stick. Putting paper or film between the battery and the phone can also solve the problem of poor contact caused by loose batteries.

1. First of all, the mobile phone system is faulty, which causes problems with the battery level display. This kind of problem is the easiest to solve, you can directly shut down and restart, which is equivalent to data refresh, and the general power display will return to normal.

2. Secondly, the charger is faulty, which is the main reason why the mobile phone cannot be charged, and it is recommended that users buy a charger.

3. It may be that the charger and the mobile phone are in poor contact, and the solution is very simple, which is to change the socket back and forth.

4. There may be a problem with the mobile phone battery. Generally speaking, it is rare to have problems with your phone's battery. But once there is a problem, it is a big problem and must be taken seriously.

Therefore, when it is found that the charger and mobile phone system are not faulty, you should focus on checking the battery. If the battery is found to be swollen, it means that there is a problem with the battery and must be stopped immediately, and the swollen battery is easy to cause **, which will bring serious consequences.

5. It is also possible that there is a quality problem with the mobile phone itself. If you buy a copycat phone, then there is a high probability that the mobile phone will malfunction. If it is a brand machine, it needs to be returned to the original factory for processing.
