This does not look like linear battery usage. Any idea what can cause this behavior? Usage was nearly the same throughout the whole day. #Lineageos 20 on a Nokia 6.1 plus, replaced the battery just recently.
Battery usage screen of Lineageos, showing a chart that decreased charge state quickly from 100% to ca. 80%, rather slowly down to 50%, and really rapidly from there to 1%.
@marcidy I didn't expect them to be completely linear, but this is so far off that it can't be normal behavior. Also I haven't observed similar behavior when using other mobile phones before I owned this one.
@Matt
my fault, i didn't get your expectation clearly but the info was there. I read too quickly.

You are right, that is an awful plot for a new battery, it looks like a plot for an old battery.

I expect freakazoid is right, it's stale calibration params. You should let it discharge completely and charge completely a few times and see if it gets better.

The usage pattern displayed is definitely not consistent with only 1 day.
@freakazoid I'll keep observing, let's see if it improves.
that curve looks exactely like the discharge voltage curve of a LiIon battery. Usually phones measure the energy going out of the battery, (coulomb counter) so the curve is linear (like on my Xiaomi Mi8 with Lineage 20), but who knows what your Nokia does?

It might be that some app went crazy and caused this curve, but this really looks suspicious.
@cm I already thought about some app going crazy, but this pattern is reproducible with every single discharge cycle. 😞
Did another round, just leaving the screen on with caffeine at full brightness, close to no interactions. Similar pattern, I'm not completely sure but it looks to me as if the fast drop in the curve starts at a lower percentage, somewhere around 30%. Will do some more tests, e.g. with mobile or wifi disabled.
probably your battery is broken?
@debian Hmm, that would be really bad, I exchanged it just a few weeks ago.
so I assume you already did the 10 times charging cycle? If the battery still does not have full capacity, I am afraid you need to buy the next one ... There is so much garbage available 🙁
@debian I usually charge my phone every night, most of the time it is below 10% in the evening, I hope that counts as 10 ties charging cycle.

Right now running another test, disabled mobile data and wifi, I'm at 70% after 18 hours now, so I assume it's more an issue with either radio or some app going haywire when it has network connection available. I'm curious about the lower area with mobile data and wifi disabled.
yes, this looks again like the battery goes down normal until the end of capacity is reached and than rapidly goes down to zero
Misusing the fediverse as a notepad now. This is the curve with wifi and mobile data off. Nearly two days, but again the same curve pattern. 🙁
I can't see the system. Only few components on my system I see additional system components on an additional view.
@hkrat Sorry, I can't follow what you mean by that.
I have an application view and system view on Android 13.
Otherwise you have to fall back on the adb.
e.g. adb shell dumpsys -l
In Android Studio there was a Power Profiler. but I have no experience with that
