DescriptionWant to know the available battery level even when the phone is locked? 'Display Battery Usage' is the answer.
*Displays current battery level in percentage at the left side of the status bar always.
*Displays the battery consumption graph by your phone for the current day.
I found it use full to know which part of the day is the busiest for my phone and to know any unwanted app is reason behind the battery drain at the wrong time.
