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 had to search for it using the search function, it wasn’t in the same place as the other screenshot that was posted

        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%).

              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.
