Here you see the result of my best values achieved in my “real life usage”.
It is with a very low overall usage and a high percentage of stand-by time - and I am still far from happy with this:
Some numbers of the Android Battery screen:
- WLAN: 2d3h = 32%
- Stand-by: 3d19h = 23%
- Display: 2h19 = 17%
- Calls: 1h20 = 6%
- Provider/SIM-Stand-by: 3d21 = 5%
- Android System (active CPU): 1h30 = 2%
- Android OS (CPU): 1h7 = 1%
I am using “conservative” as CPU governor for ALL (!) cores, and have CPU frequency always limited to 1GHz (instead of 2.5GHz) and never used the display with full brightness.
The havey drops in the curve are either some surfing (10min?!) or doing a call (5-15min?).
All-in-all a usage of about 2h19 with activated display and 1h20 doing calls not achieving 4d duration althoug I really used the total battery capacity (98%) is not very satisfied.
With my FP1 I could EASILY do the same and only go from ~ 90–>20=70% battery!
So there is massive room for improvment, althoug I not really know, HOW?!
If I calculate overall consumption: 98% / 3d20h = 1%/h
During the night I normally have 0.4-0.5%/h with 2 activated SIMs (FP1 had 0.1%/h).
I will continue to work on it - any suggestions how to improve?
