I noticed, that once I activated the Always on Display (AoD) the phone is not entering deep sleep anymore.
I did not use any AoD apps, but the stock Android “Always show Date and Info”.
With AccuBattery I get ~3,6%/h (Display off, wake), with 141 mA and 0m in Deep Sleep.
I suppose that’s one of the major issues for having such a high battery drian with Always on Display. Can anyone confirm this behavior?
