Battery Monitor 3 is an Android application designed to keep track of your device’s battery status. This app offers a variety of features, such as displaying an icon on your status bar to let you know how much battery capacity (%) you’ve got left, placing a widget on your home screen that shows both battery capacity (%) and estimated remaining time, and keeping a record of changes in remaining battery capacity and device temperature and displaying the results in graph form.

One of the best things about Battery Monitor 3 is that it allows you to choose when and how you’re notified. You can receive notifications via ticker-text message on your status bar whenever your battery status changes, set an alarm (with or without vibration) to sound whenever a set capacity level has been reached, and turn off all of the notification features to have full control. Battery Monitor 3 is designed to reduce the load on your battery by automatically adjusting the number of times the app monitors your device’s battery according to the status of your device.
