After the mobile phone is automatically turned off, the text messages and phone calls are gone. How can I get them back?

1. The protection circuit in the lithium battery is too sensitive, and the power will be cut off when the current is high.

2. The battery itself is aging.

3. There is dirt on the metal sheet at the contact position of the battery, which leads to poor contact of the power supply.

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

If the first two problems are found after inspection, they must be sent to a special repair shop for repair. If the latter two problems are only because the battery metal sheet is dirty and oxidized, 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 mobile phone can also solve the problem of poor contact caused by loose battery.
