I estimate that there are two possibilities:

1.The phone battery is broken, or the metal piece is in poor contact.

2.The Android system may be unstable.

Try it with another battery first, if it's still in the three-pack period, hurry up. After changing the battery, it is still suddenly shut down, check whether there is any foreign object or something in the contact piece of the battery on the fuselage. If it's a system problem, consider brushing the system.

It is advisable to find a professional for examination.

Dear Lenovo users, hello!

We apologize for the inconvenience caused by the use of your mobile phone.

According to the description, the frequent automatic shutdown of the mobile phone may be caused by poor contact or malfunction of the mobile phone battery.

You remove the battery by removing the back cover of your phone and wiping its metal contacts. If you feel that the contact with the phone is too loose, you can use a piece of paper to tighten it and take a look.

In addition, if the battery is restarted and the battery jumps abnormally, this situation may also be caused by the abnormal battery metering data of the system. It is recommended that you back up the data, restore the factory settings, and clear the battery metering data before testing.

If the problem persists, it may be caused by a damaged battery or an abnormality related to the motherboard. You need to take the time to go to the local Lenovo after-sales service center and let the engineer help detect and solve the problem.

You can log in to the official website to check the address.

I bought A789 and couldn't wait to set up a pass, and then every noon or afternoon inexplicably shut down, the 7th day really can't stand it, I want to change the goods, because there is no time to change, Wanbang has no choice but to think about it, is there a problem with the timing shutdown set inside, carefully study it and there is a problem, turn it off, and there is no automatic shutdown.

The same phenomenon, the battery has been padded very tightly, the factory settings have been restored, the software has been fully unloaded, or it has not been solved, the next step is to flash the machine, it will be scrapped if it doesn't work, and the mobile phone has been used for 1 year.

The A789 battery is easy to loosen, and a piece of paper is put on it.
