The history screen, part of Battery Manager, shows a text view of recorded battery data.
The first column contains 2 sets of color bars, first is the charging status, green for AC, blue for USB and red for Wireless. Second bar shows screen-on time, the darker it is the less screen-on time.
The data next to the date can be set to show mA, %/h or mW. Tap on a value to switch between %/h and mA/mW. You can decide to show mA or mW throughout the app in app’s battery settings.
Long-pressing the text allows to:
- Add a marker
- Remove selected record
- Switch viewing full history and % changes only
- Switch viewing %/h or mA in history
Long-press a marker to edit or remove it.

IMPORTANT NOTES:
- By default the app only shows data when % is changing. Long-press a recording to switch between a full view or % change view.
- The mA column as shown on screenshot can be switched to display %/h. Simply tapping the header or data does switch between %/h and mA.
