Yeah.
Unless you fully charge it till 100% the stats does not reset.
Fully charge it, use it, charge it again until it's lower than 100% and the stats does not reset, and show more than actual timings.
Or
Just play music with screen off all the night, and music playback will be counted as usage time. Play music overnight, and then in morning it will drain 10% battery with 8-12 hours usage time.
Its that easier to mess with.
They are using other techniques like low brightness, music playback etc to show more stats, that's why it's very different.
