Follow up on the Pixel 8 Pro battery life post from a couple of weeks ago (lemmy.ca)

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.

Thanks for doing the research on this! Not seeing that setting on my device yet, but I might need a newer build of 16 or something. Good info to know!

[–] kmartburrito@lemmy.world 7 points 4 months ago (1 children)

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

Just did the latest GrapheneOS update and still dont see it - maybe it's only in stock Android?

[–] ryannathans@aussie.zone 9 points 4 months ago (1 children)

Graphene has had a better version of this for ages

[–] InternetCitizen2@lemmy.world 5 points 4 months ago

Nice, going to flip that switch

[–] kmartburrito@lemmy.world 5 points 4 months ago (2 children)

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

[–] kmartburrito@lemmy.world 2 points 4 months ago (1 children)

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.

[–] ryannathans@aussie.zone 1 points 4 months ago

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

[–] Markaos@discuss.tchncs.de 0 points 4 months ago (1 children)

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%).

[–] 0xd34d@sh.itjust.works 1 points 4 months ago (1 children)

It's still there in there latest Android 16 builds

[–] Markaos@discuss.tchncs.de 1 points 4 months ago

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.

[–] lightrush@lemmy.ca 1 points 4 months ago* (last edited 4 months ago)

Reactivated the Battety health assistance setting and we're back to 91% capacity:

[–] lightrush@lemmy.ca 1 points 4 months ago

Another full charge session clocks at 96%.

Then yesterday I found this curious setting, after updating to Android 16 QPR1:

Would you kindly post that image in the comments section? It just display a blank area for me.

[–] lightrush@lemmy.ca 1 points 4 months ago* (last edited 4 months ago)

But basically search for "battery health assistance" and you should find it.
