Welcome

Watts is just something I wrote for myself so I could get a visualisation of what my battery was doing and what tasks affect it the most and I've put it on the market simply because maybe others will find it useful too.

If you dislike the marketplace point your barcode scanner at the QR code to get a download link for this app.

Please log bugs by clicking "Issues" above and adding a new one, please include as much information as you can (and if you're a fellow developer the output of a adb logcat). I can't fix bugs if I don't know about them :)

Quick Usage Instructions

Some basic usage instructions:

• run the app when you want to start collecting, it will then collect until phone gets rebooted but won't start again unless you start it
• most recent battery levels are on the left, going further back in time to the right
• this might change to a configurable option soon as I know it's not to all peoples liking
• pressing menu allows you to quickly change the zoom level
• select "finish" from the menu if you want the app to quit running and stop collecting battery data
• rotating the screen without opening the keyboard will do what you'd think
• NOTE: this app does not poll the battery instead it sits back and waits for OS notification that a battery event has occurred, so this app itself should not impact on your power consumption unduly.
