Main Screen

The main screen of the application is either started from the application list, from a click on an active widget or from a notification in the status bar.

History

The history screen displays battery history data. The drain/charge data can use mA or %/h units, switchable tapping a value. Pro user can also manage history marks from that screen.

Estimates

The estimates screen shows you how much time remains to finish charging or draining the battery. (how estimates are calculated).
 

Calibration

This screen helps maximize battery capacity and measure its aging. Why and how to do calibration is explained in this faq.

In this screen, Pro users can update the reference battery capacity (mAh) using the measured mAh, but need to be careful as it impacts the estimated times and could also impacts the mA readings. Please check this faq about the "Update mAh" button.

Please also refer to that page for more details.

Graphics

The graphics can be shown in full-screen by a long-press on the main-screen graphic (default) or using the context menu shown after a long-press (optional). See settings for more information.

IMPORTANT: Graphics are disabled when history logging is disabled.
 

Notifications

Notification can be used to show battery-related information in the status bar. Application is package with basic space-saving icons, but external package can be used to display accurate %, temperature and current information. See settings for more information.
 

Alarms

Alarms can be triggered based on the following events:

  • Battery full (100%)
  • Battery fully charged (100% and 0mA)
  • Voltage out of range (user-defined minimum-maximum)
  • Temperature too high (user-defined temperature)

See settings for more information.
 

Widget Usage

The widgets are highly customizable, changing their visual aspects and selecting which data to display. Any active widget is refreshed as soon as battery information is updated (event-based for all information, except mA/mW which requires polling).

See settings for more information.
 

Settings

All settings are described in this page!
