I noticed this yesterday and reproduced it today. The the battery charge remaining on my z10 increases after I restart the device. I first noticed it in the phone info (in settings) which reported 10% increase (from 80% to 90% remaining), but since that only rounds to the nearest 5, I checked it with Battery Guru today and it shows it to be around 6% (from 62% remaining to 68%). Anyone else experiencing this?

it can take a week for the battery calibration to be accurate with several charges/discharges

Battery calibration data is only stored when the phone stays on. After all, if you turn your phone off, the phone doesn't know if it's the same battery. (A restart is really just turning the phone off, then on again)
The change in the percieved battery level doesn't actually reflect the actual charge level.
Don't worry about it.

Hmmm... well, if that's true, then that's a somewhat silly way of monitoring the battery. The usage stats in the OS should be non-volatile, otherwise the end user would experience all sorts of problems especially with charging. Although, maybe its true, given the charging issues I've seen reported, like some phones only charging up to 50%
It's not really a big deal I guess, but it makes me wonder if there's a larger issue.
