"Some users suggest clearing the app cache from recovery mode and waiting 14 days to let One UI 7 learn your usage pattern. It's common for Android devices to consume a bit more power after a major OS upgrade, as they optimize everything in the background.
However, battery life should return to normal after a few days. So, if you have only updated your Galaxy phone to Android 15-based One UI 7 in the last few days, wait at least a week."
I have said this as well except only on reddit and getting downvoted to the ends of hell.
I have also had the same issues. The issue affects a mix of exynos and snapdragon users so u cant blame their pick of using VULCAN instead of OPENGL.
It will affect NZ users essentially because the script for the new software is the same.
If youve cleared the cache partition, and done all u can my only assumptions for this issue is the "re optimisation that an android needs to go through after a major os upgrade " as they call it.
