Battery Full Alarm is an app that monitors the charge level of your mobile phone and notifies you when the battery is fully charged. This is useful for people who need to stay connected to their mobile devices at all times and don't want to miss any important calls or texts.

If you are a user of Xiaomi or OPPO mobile phones, you can set the app to work with your phone's default settings. In this case, you will need to add the app to your phone's security settings.

This app is also useful for people who want to protect their phone from overcharging. It can notify you when the battery is fully charged and you can stop the charging process.
