90% or 80%
The Mi 14 has 90 watts of wired charging power, which can be charged to 100% in about 36 minutes, while the actual maximum speed is 70W. In addition, the phone also supports 50 watts of wireless charging, and other devices can be wireless backcharged. Therefore, from the point of view of charging efficiency and battery protection, it is recommended to stop charging when the power reaches 90% or 80% to avoid the damage that may be caused to the battery by overcharging. The specific percentage of charging is appropriate, and it also needs to be determined according to personal habits and needs.
