The reason why the battery icon of Xiaomi mobile phone turns white may be because the phone has turned on the power saving mode, which can reduce the power consumption of the phone and extend the use time of the phone. In Power saving mode, the battery icon turns white to remind the user that the phone is in power saving mode at this time.
In addition, when the phone battery is too low, the battery icon will also turn white to remind the user of the need to charge in time. If you need to cancel the power saving mode, you can find the \"power saving mode\" option in the Settings, and turn it off.
