Question - is the bypass charging feature in effect when the 80% is turned on? Meaning, when charging to 80% and leave the charging cable plugged in, would it trigger the bypass charging feature and not charging the battery over 80%?
Charging optimization (80% charge limit) recalibration with Android 15 QPR2

Not a dev, but seems like a yes if there's a shield icon.

The 80% feature seems to be bugged now on the Pixel Tablet. It will keep charging to 90%. My guess is that it's trying to reach 100% for the calibration, but it can't reach it because it's limited to 90% elsewhere.
Pavestone2734 Thanks. I'm still on 2025030300 (Pixel 8 Pro stable), looking forward to 2025030800.
GrapheneOS Since you mention best practices, particularly regarding bypass charging with USB-PD, I would like your thoughts on low charging for comparison. Does charging the phone battery with an underpowered charger( 5V 550mA, 2.75W for instance) and keep the battery between 20% and 80% a good practice for battery life ? How do you think this compares to using USB-PD in the long run? Is there a risk of damaging the battery with an underpowered charger?
My tablet loads to 94% and says it is fully loaded. Is it supposed to be like that? Is the real capacity 94% and it will load to 80% of that after calibration?
Does bypass charging work on Pixel 7?
On stock Android bypass charging is only available for Pixel 8 and newer, but my Pixel 7 Pro does have the 80% charge limit, does it mean I also have bypass charging and can leave the phone plugged in?
When it reached 100% I had to leave my phone plugged in for nearly half an hour before the shield icon appeared. Just an FYI for other impatient souls out there. 😊
fid02 Yes, it was something between 30 to 40 min for me, Pixel 8 PRO.
Thanks for the tip
I have a question: Does the bypass charging also works with wireless charging (Qi)?
I only got to 98% before the shield appeared. I left the phone charging overnight, around 7 hours in total. It's my first charge after installing 2026030800. Is this working correctly? It used to hit 100% before charging optimisation was switched on.
Popped on to see what the fuss was about (mine went above 80% too). Thanks for the info @GrapheneOS about how this (+recalibration) actually works 😁👍
In my case, it charged up to 100% and after a while the shield icon appeared. But then the charge level slowly decreased, even though it was still hanging on the charger. I would have expected it to stay at 100% for a very long time. Was that the case for you too?

left mine over night, the battery was at 93% when i disconnected so mine seem to behave in the same way.
OK, Thx! :)
