1. The whole charging process includes three stages: fast charging, continuous charging and trickle charging. After the first two stages, the battery will display 100%, but the actual battery has not reached the saturation state. The remaining capacity can only be supplemented by tiny pulse current, which usually takes 30-40 minutes.

2. Charging the mobile phone with a computer is not a big problem, but the unstable current output caused by using the computer will cause some damage to the battery. Selecting "charging only mode" for Android phones can effectively speed up charging and minimize the impact on mobile phones and computers.

3. Generally, the chargers of various manufacturers have personalized needs. Do not change the charger at will when you are not sure. In addition, do not remove the speed limit of the controller. Although the speed limit of the controller can improve the speed of some cars, it will reduce the service life of the battery.

4. Under normal circumstances, a new mobile phone usually has a certain amount of power, but the lithium-ion battery will enter a dormant state after being placed for a period of time. Therefore, many people mistakenly believe that a new mobile phone can only be used after being fully charged for 12 hours. In fact, the current mobile phone can recover its normal capacity as long as it has been charged and discharged normally for 3 to 5 times. A long time of power on will not activate the lithium-ion battery but will cause great damage to the battery itself.
