REPRODUCIBILITY (% or how often): Always
BUILD ID = OS VERSION (Settings > About product): 4.1.0.24
HARDWARE (XA2, Xperia 10…): Xperia X
UI LANGUAGE: Swedish
REGRESSION: (compared to previous public release: Yes, No, ?): Yes
DESCRIPTION:
I experience higher power consumption since updating from 4.0. There have been reports connecting this to WLAN use, but that is not the issue here, as far as I can tell.
I have tested as below to see if I can find a culprit app, to no avail. It looks more as an OS problem.
Please advice if there is anything more I should test.
PRECONDITIONS:
In order to provide consistent data, I have
- Charged to 80%
- Switched off all radios (mobile, WLAN, BT) and GPS
- Powered off the device
- Powered on the device
STEPS TO REPRODUCE:
- Setup as above
- Start zero or more apps
- Show home screen
- Leave device idle for 10+ hours
EXPECTED RESULT:
A drop in battery around 0.3%/h with four apps idle. Several days of light device use on a charge.
ACTUAL RESULT:
Apps running Discharge
----------------- -------------
None <0.2%/h
Settings 0.4%/h
Calendar 0.4%/h
Four apps >1.4%/h
The four apps were Settings, Calendar, Situations and Pure Maps.
ADDITIONAL INFORMATION:
- Under Koli 4.0.1 with these four apps “running” (i.e. idle), I could expect about the same discharge rate as Kvarken 4.1.0.24 shows with no apps at all.
- It seems more power is consumed when I actually use the apps, in comparison with Koli 4.0.1, but that is hard to measure. I get 0.5-2 days of use from a charge now.
- It seems apps are slower to start and more sluggish to use, in comparison with Koli 4.0.1, which also hard to measure.
POSSIBLY RELATED:
(But please note that my testing is with WLAN off.)
