(*) In order to get a value, which allows to compare test results with different screen on times for mixed usage battery tests, I tried to „normalized“ the battery loss per hour with the following formula:
loss*(1-screen): battery loss in % (per hours) * (100% - screen on time in %)
So, it would be the battery loss in % (per hour) for the screen off time.
That is how a kernel with the same battery loss per hour will get a better/lower value, if it has more screen on time. (And the other way round.)
