de0u I'm not reffering to the apps or graphene's battery optimization, it has to be some type of issue, i detailed it in a separate post.
For refference my last phone was a 6a with graphene and had better battery than both stock and my pixel 9a with even more apps and 500mAh less. In the first months the 6a ran around 40h without issues, but my new 9a is dead in 5-6 hours with 11 battery cycles and nothing running in the backround, the data usage being only 26%.
