2. We do the exact same activities for the exact same length of time.

We can then compare % loss. Seeing as that is never going to happen (as a truly fair test) the best we can go on is mAh loss/gradient decline.

If you want to get really clever you could break down the gradient into an equation, that would be the best comparison.

Yes there's a really informative post by woody14619 that explains the battery percentage thing.

It would probably be better to get the raw data that Batterygraph collates and stick that into a spreadsheet.

How about this for a scientific test.

Test conditions
Charge phone until fully charged (green light)
Reboot phone
Close all widgets
Turn off Wifi - no random email/ IM notifications
Put phone into tablet mode - no random telephony
If Brightness status bar applet installed check level and note.
Set volume to standard eg full or 3 clicks down etc.
Start conky and note battery starting conditions, also note time.
Play media off local storage - eg full album or movie
At end of music note end conditions

This should ideally be done 3 days on the trot,with minor adjustments:

Day 1 - don't play any music - conrol test
Day 2 - follow test fully
Day 3 - run script after reboot and run test.

The reason for consecutive days is that there moght be cron jobs running in the background, and if you start at the same time every day then you can negate their effect on the test.

I haven't tried the scripts yet so I will try to run the test over the next few nights.
