S22 ultra Issues is it common

[BSuvarna]

1) battery doesn't last long

2) crackle noise when I move the phone from.camera lens

My phone is on latest OS. Its a UK version with Exynos smartphone. 

So please give suggestions, my old S20 last 1 day from full charge, but my S22 ultra doesn't last even half day.

I have done the partition clear today. Any other thing to do. I read recently that disable adaptive battery and set the processing to high from optimised does help battery in some ways. Is that true.

Thanks for posting these. Do you mind doing this after charging the phone fully and letting charge run low without putting it on charge mid way?
Thanks
