Lenovo 90t mobile phone charging automatically shut down

Hello! Many netizens say that their mobile phones are easy to turn off automatically, and they complain about the quality of the mobile phone or the poor brand when there is such a situation. Actually, the phone since.

The phone automatically shuts down.

The reasons for the general automatic shutdown may be as follows:

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

2 The battery itself is aged.

3. There is dirt on the metal sheet at the contact point of the battery, which causes poor contact with the power supply.

4 The joint between the battery and the mobile phone is prone to loosening.

5.I set up an automatic shutdown by myself, go to the settings to check it myself.

If, after inspection, it is found that the first two problems are the first two problems, then it must be sent to a specialized repair shop for repair. If it's the latter two problems, it's just battery gold.

It is caused by the oxidation of the dirt of the piece, as long as it is wiped clean with a glue stick, the situation will be improved. Place a paper or film pad between the battery and the phone.

It can also solve the problem of poor contact caused by loose batteries.

2 The battery itself is aged.

3. There is dirt on the metal sheet at the contact point of the battery, which causes poor contact with the power supply.
