So I have an update to my post from a couple of weeks ago. I did a few full charging sessions and they all showed estimated capacity around 4700mAh:
Then yesterday I found this curious setting, after updating to Android 16 QPR1:
I turned it off, did a full charge session and I got this estimate:
And that result looks to be right back to the normal cycle degradation line:
I’ll do a few more full charge sessions but we have a tentative culprit. Google seems to have introduced a battery capacity cap under this setting, presumably to extend the cycle life of the battery.
I bet it’s not on grapheneOS. I saw a couple posts surrounding GOS where people were complaining about the feature, so I’m wondering if they removed it in favor of allowing you to set a charging limit like we had before this feature was added.
Unfortunately the only pixel I have GOS on is my pixel 6 pro, so I can’t be of more assistance.
Wait, did Android 16 QPR 1 remove the charging limit for newer Pixels? My 7a has both the Battery health assistance option and the original optimization modes (off, adaptive charging and 80%).
It’s still there in there latest Android 16 builds
Charging limit is a far better implementation as it prevents the rapid aging in the first place
100% agree! I try to keep the 20/80 rule for all of my devices. Lately, however, my 8 pro has felt extra bad with battery, so I’m hoping disabling this battery health assistance feature will help.
I’ve almost factory reset my phone a couple of times too, hopefully this is the missing link.
