I have updated to android 15 in my iqoo Neo 9 pro and totally disappointed with battery backup which i am getting after update. I was getting screen on time of 8hours+ while I was on android 14 and after updating to android 15 I am getting just 3 hours screen time which is so disappointing. I am attaching screenshot of battery performance in android 14 vs 15. No doubt smoothness increased after this update but battery sucks.
