thure user I would be very grateful if someone with more knowledge on the topic could share their thoughts.
xmesc Does anyone have an update on this? Did you guys calibrated by yourselves? Mine hasn’t done a 100% charge since June I think.
sudo777 xmesc Hi, I am using a new Pixel 9a since the end of July and I also run into this issue. I checked Github for open issues and couldn't find anything related. Should I create a new issue there or do the developers also check for issues on the forums? Thanks.
xmesc sudo777 They do check here but the GitHub will always have priority so you can open an issue there. It would be helpful to know if this is an upstream bug (android 16 bug) or a GOS bug. I really can't tell since it's happening right after we all updated to A16. In the meantime I'm just calibrating manually once a week.
Quantum I didn't know this post existed. I had shared some thoughts about the same issue in this post: https://discuss.grapheneos.org/d/24609-battery-preservation-settings/15 Basically the same conclusion though.
sudo777 Here is the link to the issue on Github: https://github.com/GrapheneOS/grapheneos.org/issues/1235
harp sudo777 One of the devs (seemingly Daniel Micay himself) moved the issue to the correct repo, now it can be found at: https://github.com/GrapheneOS/os-issue-tracker/issues/6024 (The grapheneos.org repo is related to website concerns.) He also added the 'upstream' label, so it seems to be an AOSP issue.
sudo777 Quantum So I thought I'd check up on the issue on Github. My phone hasn't charged to 100% in the meantime with Charging Optimization enabled, but I am not a heavy user. Can anyone confirm their phone has charged at least once to 100% with Charging Optimization enabled? Thanks.
Quantum Watermelon idk, but I did try to link them up before. I thought I'd update both so people would know if it's fixed atleast.
Quantum sudo777 People have made like 20 different post about this by now. The new problem is that it's calibrating the battery on each reboot. Check the link above for more discussion on the subject.
thure sudo777 I have the same problem with my Pixel 9a. I've been using battery optimization for six months and no automatic calibration has been performed. Are there any factors that can influence automatic calibration? Where could I start troubleshooting?
KitsuneNoBaka Quantum No. Since 14.12.2025 and 2025121201 compilation there is no calibration after every reboot. Actually, since then, I've had no calibrations at all.
Quantum KitsuneNoBaka Im still waiting to see if itll calibrate. Maybe its broken in reverse now, but at least this way you can manually calibrate it
KitsuneNoBaka Today, 8 days after update, battery finally is calibrating (gone over 80%) by itself. PS: edited, because from 14 DEC to 22 DEC is not 2 weeks 🙃 PS2: I'm charging twice a day
