What does "usage" actually mean in battery stats?
In the summary table "Time since last full charge", my phone currently says "Usage 2 hours, 41 minutes" and "Standby 8 Hours, 23 minutes".
The "Standby" part I get....it has been that long since I disconnected the power supply.
But the "Usage" part......is that essentially "screen on" time, or does it also include time when there were things active in the background?
I'd really like to know what my screen on time per charge is, so that I can plan ahead for things like trips on pubic transport.
Thanks.
