Automatic shutdown of mobile phone: normal and abnormal situations

Automatic shutdown of mobile phone is a common problem, which may be caused by many reasons. This paper will introduce two cases of automatic shutdown of mobile phones: normal automatic shutdown and abnormal automatic shutdown, and provide some solutions.

Normal automatic shutdown

Normal automatic shutdown refers to the situation that the battery of the mobile phone is exhausted and the ic value is lower than 10%. At this time, the mobile phone needs to be recharged. If this happens frequently on your mobile phone, I suggest you buy a spare battery or a charging treasure.

Abnormal automatic shutdown

Abnormal automatic shutdown refers to the sudden shutdown of the mobile phone when the battery is sufficient, especially when talking, texting, using GPRS or taking photos. This situation may be caused by a variety of reasons, including leakage of the main board, over-sensitivity of the protection circuit, aging of the battery, unclean contact position of the battery or loose metal sheet. If your mobile phone is turned off abnormally, it is recommended to check whether there is any problem with the battery and motherboard, or seek the help of professional maintenance personnel.

Repair and maintenance

If your mobile phone is often turned off automatically, it is recommended that you check whether there is any problem with the battery and motherboard, or seek the help of professional maintenance personnel. At the same time, cleaning the battery metal sheet regularly can also prevent abnormal shutdown.
