So after using the Android 15 update for 2 weeks the battery life is still terrible forcing me to use ultra durable mode to reach the end of the day with 20% left. Normal i was using Dynamic mode and ended the day with 40% left. ( yes my device was running the Beta version before and the latest update V35.1210.1420.78 was also a beta that got s stable release).
I did try to empty the phone and let is recalibrate it and re learn my usage but no succes. So there is 100% something faulty about that update because normal it wil sort it self put after a week.
Other things are maybe the background app monitoring is broken.

After using the Android 15 update for 2 weeks the battery life is still terrible. Google play services really drain the battery. It shows that what is draining is not particular apps but generally CPU and system apps. phone's CPU never enters to deep sleep mode. One strange thing I have found is that the I connected to charge is CPU entertaining the deep sleep.less power when charging than it does when using the battery.
