Mobile phone hot causes:
1. The processor is a heat generator The processor is a highly integrated SOC chip, which not only integrates the CPU central processing chip and GPU graphics processing chip, but also a series of key chip modules such as Bluetooth, GPS, radio frequency, etc., when these chips and modules operate at high speed, they will emit a lot of heat.
2. During the charging process, the power circuit is in operation when the resistance is working, the resistance and the current are playing with each other, and the heat is definitely inevitable, and it is mainly concentrated on the battery and PCB board.

During long conversations, avoid pressing the phone against your cheek and use a receiver or earpiece as much as possible.
