Just some days in the past, OnePlus pushed a rather big update to the OnePlus 9 sequence addressing some software program, digicam and battery points. Nevertheless, it appears that evidently the replace to OxygenOS 126.96.36.199 did not go so effectively for the OnePlus 9R and brought about some battery drain issues.
The hotfix to OxygenOS 188.8.131.52 appears to deal with simply that. The changelog is fairly quick nevertheless it additionally vaguely mentions that the patch solves a identified subject. Feels like a minor bug has been squashed.
Anyway, OnePlus says that the rollout is incremental and it might take a while to achieve all OnePlus 9R models. The file measurement is small – round 106MB.
