1.Misoperation to turned on the power shutdown timer.

Many mobile phones have the function of timing shutdown. After simple settings, the system will automatically complete the shutdown operation at a specified time. Different from manual shutdown, the program will execute the phone shutdown command at a set time point. And when we don't need the phone to automatically shut down, we only need to turn off the timer shutdown function to solve the problem.

2 .The temperature is too high or too low, causing the phone to automatically shut down.

Smartphones typically use lithium-ion batteries which chemical activity is affected by ambient temperature. The lower the ambient temperature, the lower the chemical activity of the battery, and the faster the power consumption; the higher the ambient temperature, the higher the chemical activity of the battery, which will accelerate the aging process of the battery. If the ambient temperature directly affects the battery, the battery protection program will be activated and the system will force the phone to shutdown or restart until the battery temperature reaches a standard level. If we want the phone to work normally, we only need to change to a suitable temperature environment.

3 .The charging power of the charger is too low to maintain the hardware working.

This kind of failure usually occurs during the charging process. When the mobile phone is charging, the power adapter will directly provide voltage to the mobile phone while charging the battery to ensure its normal operation. If you use a charger with too low output power, the phone cannot be guaranteed to function properly. At this time, the phone will continue to consume battery power until the battery voltage is low and the system automatically shuts down. This is also often said that the battery is "the more you charge, the less power you get". In addition to the reason of the charger, the oxidation of the charging flex of the mobile phone can also cause this problem.

4 .Long time using cause the battery to age quickly.

As the power source of the mobile phone, a seriously aging battery will also cause the mobile phone to automatically shut down and other failures. The life of the battery is usually limited by the number of charging and discharging times. If you do not use a standard charger or use the mobile phone in a high temperature environment for a long time, the aging speed of the battery will be accelerated. After the battery is aged, the capacity of the battery decreases fast. At this time, the mobile phone may have automatic restart, automatic shutdown and other failures.

5.Other hardware failures.

This type of failure often occurs after the phone is been heavily dropped to the ground or got into water. Water in the internal side of the mobile phone can easily lead to a short circuit on the phone’s main board. And after a heavy fall, it is easy to cause problems such as disconnection of the main board, integrated circuit or board layer connection to fall off. In addition, if the power flex cable is damaged, it may lead to failure too. For hardware problems, it is not recommended that users disassemble and repair the mobile phone alone. In this time, you should go to a professional maintenance store to get your phone repaired.
