The screen is listed and is, of course, the major use. I'm interested
in the UNLISTED usage. Current example:
Screen 17%
Phone idle 10%
Camera 7%
Wifi 3%
Android System 2%
Google play services 1%
Android OS 1%
TOTAL: 41%
BATTERY REMAINING: 37%
Total: 78%
This leaves 22% of the battery drain a mystery. Internal working?
Rounding error? Magic? That's the stuff I want to know about.
I have to assume that the 'native' battery monitor also uses 3% of the
battery, so the apps just add another 3% without providing any
improvement. Is the 'native' battery thing included in 'Android
system' or 'Android OS'? Apparently not, since those are 2% and 1%.
