[Health charge]
Step 1: Quick charge → Step 2: Full charge → Step 3: Trickle charge
As fast charging progresses, you can change the settings for Wi-Fi, Bluetooth, screen brightness, synchronization, etc. to speed up charging.
But it does not guarantee charging speed.
When charging is complete, disconnecting the cable or stopping the fast charging, you will return to the previous setting.
It never damages the battery or shortens the battery life.
Keep your battery healthy with a healthy charge.
