Xiaomi mobile phone does not provide a \"fully charged automatic power off\" function. This is because when the battery is fully charged, the phone will automatically stop charging, but it does not mean that the power will be completely cut off. The phone still maintains a tiny current to keep some basic functions running, such as alarms and notifications.

If you're worried that overcharging might hurt battery life, you might consider turning on the \"Smart charging\" feature. This feature allows you to delay charging for a set period of time, such as at night, in order to extend the battery life.

The steps are as follows:
< br >
Open the Settings app.
Slide to \"Battery and Performance.\"
Click \"Battery\".
Find and click \"Battery Charge Protection\".
Turn on the \"Smart Charging\" function and set the time you want to delay charging.

Please note that these steps may vary slightly depending on the MIUI version.
The method of setting automatic power off on Mi 13 Ultra is as follows:
< br >
Use third-party apps. You can download a third-party app, such as \"Battery Charge Limit,\" to limit the amount of charge you can charge, so that you automatically power off when you are fully charged.

It should be noted that the use of third-party apps may pose certain risks to the phone, such as incompatibility or security vulnerabilities. Therefore, before using third-party applications, be sure to confirm their source and security, and exercise caution.
The Mi 13 Ultra can automatically power off after a full charge through the battery optimization function in the Settings. Open the Settings, find the \"Battery optimization\" option in \"Battery and Performance\
When turned on, when the battery is fully charged, the phone will automatically power off to avoid overcharging, thereby extending battery life. At the same time, it is recommended not to use the fast charge function for a long time to ensure normal charging time and better protection of the battery.
