aBattery

iPhone / iPod Touch (2nd gen) – Requires OS 3.0 and above

This sleek and elegant battery monitoring application displays the remaining Talk 2G/3G (iPhone only), Internet, Audio, Video and Standby time. aBattery captures the current state of the battery at app startup, and every time the battery level or state (discharging, charging, or full) changes while the app is running. You can then see a graph of the data, and even e-mail the data to analyze later. The graph dynamically updates every time the state or battery level changes.

Automatically detects your device, and displays only the relevant information for your device.

Make sure to check out the app in landscape as well as portrait mode.

Some useful ideas on how to use aBattery:
- See how much Talk and Internet Time you have left
- Collect the health of your battery
- Analyze the historical charging and discharging time for your battery
- Any other ideas you come up with!

The graph legend is:
Green dot – Battery Full

For maximum performance, make sure to clear the battery history by going to the history tab and clicking Clear History. If you would like to keep a copy of the history for viewing later you can e-mail it to yourself before deleting the history.

The file format of the history data is a plain text comma separated value (CSV) file. You can open this file easily in iWork, Excel, OpenOffice or any other spreadsheet application. You can even open the file in a text editor.
