IOS 15 beta3 battery drain

When I upgrade to IOS 14.5.1 (iphone XS) pull my battery drain 15% in 3h. Than I install 14.6, 14.7 beta, but nothing new - 17% in 3h. Now I m in 15 beta 3 and still have battery drain 4% / h over day or night. Battery health 86%. Please, do something, because this it takes too long, please answer what to do, I try everything.

Exactly! That goes the same to the current iOS 14.6.. The battery drain still have not been fix.

I downloaded iOS fifteen RC on my iPhone mini post which I’ve been in remorse as the battery reaches 69 percent using the iPhone for mere 40 minutes! That too just safari or Instagram and no heavy loading through any games whatsoever on the device! Plus the device is so heated up that at one point of time you can’t hold it good. This seems a pathetic update experience. Why can’t the developers concentrate on battery life as battery drain is a pain in each update and a waste
