Weird battery bug! Can anyone explain?

[100rabh7791]

Anyone else facing something like this?? Also at times my battery indicator shows wrong percentage by miles and i have to hard reboot by pressing the power button for 15-20 seconds.

Example it will show 30% before and after hard reboot it will show 60%.. Something is terribly wrong.

Please find the screenshot

I have the same problem after December update. And my phone keeps randomly rebooting.

I don't have rebooting issues but this is really strange!

My rebooting issues was due to Opera (i think) being ad blocked by Blokada. Uninstalled and no more random reboot for 1 day now. The random reboot is what lead me to find this battery bug.

There is another thread that mentions about the battery graph issue which is due to charging to 80% (accubattery guudance) and thus not resetting battery stats. Habe u tried charging to 100% and see if the issue still persist? I have tried on mine for 2 times in the last 4 days but is still showing the same problem.

One screenshot showing the jump in battery percentage and another showing roughly like your screenshot. The problem with mine is that if i charge to 100%. It is ok for a while, i.e does not show 48days ago but after random reboots it goes back to the 48days ago type graph.

There used to be a battery app that deleted the batterystats.bin file to correct anomalies in battery life and not showing charge to 100%.

If rooted, you can just delete the batterystats.bin yourself, it regenerates automatically upon reboot.

Find it here: data/system/batterystats.bin

Oh! Yes it did vanish after i charged it to 90% but this discrepancy in battery percentage is really not good and I'm not sure how much I'm really charging because sometimes after I hard reboot the difference is 10%

Thanks but I'm not rooted. I can't because it is a work phone as well but do you know the name of the app?

I don't recall the name of the app. I went through the play store looking for something to jog my memory, but I don't think it got updated from 8x

Thanks! No worries!

I think I'll see for few days if it's not constant then the only option is to do a factory reset i suppose!

I did a factory reset and the problem persist so contacted Google for RMA. Lucky European region has 2 year warranty. Your mileage may vary. I suspect mine is a battery issue as it's not widespread with other user in this forum.
