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.
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.
I only used 22% on my 8 pro battery today, how old is your 8 pro? Maybe something stopping the phone sleeping? I have noticed one of my Bluetooth devices stops the phone sleeping
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
Right, but the commenter above me seems to suggest that GrapheneOS removed the battery management in order to bring the charging limit back, which is why I asked.
