[Q] Is this graph normal / nothing to worry about?

[creebefu]

The Battery Use graph will normally show these little 'peaks' down to ~75%. Normal? Or does it indicate something I need to start worrying about?

EDIT: Realized I should provide more information regarding the phone. Bought it new off of Amazon UK about two weeks before Christmas. Rooted / Flashed it within 12 hours, and these peaks have always been present since day one.

If your battery life is ok - I believe that these might be just SW miscalculations.
Especially if you always had them, I don't see a reason to worry.

This is normal for rechargeble batteries, since they have a habbit to lie their actual charge level, and the phone just graphs them. You might just get a speare one and test to see if same happens and also good to have extra battery.
