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.

    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
