Normal automatic shutdown

When the battery of the mobile phone is exhausted, the mobile phone will automatically turn off. You can check the ICH value of the battery in engineering mode. When it is lower than 10%, the phone will automatically turn off.

Abnormal automatic shutdown

Some mobile phones will suddenly turn off automatically when the battery is sufficient, especially when talking, texting, using GPRS or taking photos. The possible reasons are: the main board of the mobile phone leaks electricity, the protection circuit of the lithium battery is too sensitive, the battery is aging, the battery is in poor contact, and the connection between the battery and the mobile phone is loose.

If you encounter the problem of abnormal shutdown, you can first check whether it is caused by the above reasons. If the battery metal sheet is dirty and oxidized, you can try to clean it with a glue stick. If the problem still exists, then you may need to seek the help of professional maintenance personnel. Remember, don't disassemble the mobile phone at will, so as not to cause more harm.
