Static electricity is generated when charging
When the mobile phone is charging, static electricity will be generated, especially if the mobile phone is a metal shell, the metal shell will absorb part of the static electricity, because the shell and the screen are connected together, resulting in changes in the electric field of the screen, resulting in the screen failure when charging.
solution
After charging the phone, you can wipe the phone with a slightly damp towel or connect the phone to the computer with usb to conduct the static electricity in the phone.
Charging heat causes the phone body temperature to be too high
Due to the lithium ion movement in the battery, heat is generated, and if the heat is too large, the temperature of the phone body is too high. Both too high and too low body temperatures will cause changes in the screen electric field.
solution
Reduce the temperature when the phone is charging, it is best to remove the phone cover when the phone is charging or put the phone on the object with good heat conduction, such as the tile floor.
Operating voltage and current
Apple mobile phone charging working voltage is 5V, working current is 1A, some Samsung mobile phone charging working voltage is 5V, working current is 1A. On the charging head (charge controller) are limited current and voltage limiting devices to prevent excessive voltage or current during charging. However, in order to save costs, many high-imitation chargers do not standard in the current-limiting voltage control circuit, resulting in high working current and voltage of the mobile phone destroying the original voltage of the screen electric field. The working voltage and current of the mobile phone screen are high, and the screen failure is often accompanied by shaking, so it is best to use the original charger.
Apple xs with pd fast charging screen failure because this fast charging protocol does not meet the requirements of Apple xs mobile phone, it is best to use the official fast charging!
