Just as a data point, my Pro1 with official LOS 22.2 is having no battery problems still. About to do the May 10th OTA. I will finally be getting everything set up again this afternoon, and will report if anything changes with my, so far, good battery life. This is very puzzling.
I have upgraded it (without factory reset) to 22.2 20250503, and will recharge and see what happens. If horrible, I will try with yet another factory reset (and no MTG, no and no apps whatsoever, all left default, and skip/disable to all questions)....
At 22.1 20250405 with same setup after two hours it has gone from 100% to.... 99%
So I still claim that 22.2 is borked... Sorry.
...After 5h: 97%, 8h: 94%
At 03 I finished recharging after installing the 0503 with MTG, with only very few apps, and restricted all I can, and in just 4h11m it has eaten 31%, so there IS an issue - sorry. I will flash back to 22.1 (dirty, and if needed with a Factory reset, and recreate)
I flashed back to 22.1 (0405) with a factory reset and will recreate.
