Why does the phone turn off automatically on its own, and then

Generally, the reasons for automatic shutdown may be as follows: 1. The protection circuit in the lithium battery is too sensitive, so the current will be cut off when the current 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. 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 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.
