Latest Cyanogenmod update for your OnePlus One killing your battery? You’re not alone
June 17, 2025
It was just a few days ago that we told you about an OTA update rolling out to yourOnePlus One, toCyanogenmod 11S firmware version 30O. Along with a long list of goodies to be excited about, as it turns out, the update contains a couple little battery drain bugs that may be forcing you to plug-in a little more often than you might like.
Luckily, the issues have been noted and have the appropriateissue tracker entriesto see to a fix.
Our understanding is that, as explained bySteve Kondik, there are two issues here. The first is a power management bug that has already been fixed; should you have opted in to thenightly buildsthere is a good chance you’ve already got the fix. Stable release users can expect the repairs in the next OTA update, whenever that may come around.
The second noted battery drain issue relates to the proximity sensor, which enters a “bad” state. The result of the ‘race condition’ behind this bad state is that your device experiences excessivewakelocksand is never allowed to fully suspend. Unfortunately, there is no fix identified just yet, nor an ETA for the update that will repair things, but you’re able to alwayskeep tabs on the issueyourself if you’d like to be more involved.
Hopefully the fix is not too far out, and the resulting battery drain is not causing you too much grief. While I don’t recommend jumping ship just yet, I should at least mention that there areother ROMs out therefor your OnePlus One, likeParanoid Android, as an example.
Is anyone out there experiencing these battery drain issues, how bad is it for you?
