This app monitors your device's battery usage and estimates the battery time remaining on your device in terms of minutes and hours, not just percentage.
It has a highly customizable home screen widget available in two different sizes and will show a notification area icon and text with battery details.
NOTE: To get the most accurate readings, calibration can take several days. Charge your phone fully, leave it on charge for several hours after it reaches 100%, then let it run down all the way until it turns off.
