Battery of Galaxy S23 Ultra is abnormally draining after May'24 security update

[Rifat1986]

I updated my Galaxy S23 Ultra to May'24 security update yesterday. Since then, my phone is facing abnormal battery draining. Anyone else facing such issues post update? Is it normal after a security update? Following screenshots may help to understand gravity of the issue.

Did you by any chance cleared cache after the update ??

[Rifat1986]

Nope. Should I try that? Is that possible with Charging adapter plugged in. My PC got bricked.

[SamPro]

I don't think without PC it would boot into it's loader. You may try, but ensure to do this step.

It worked only after connering to laptop via USB. Cleared cache from recovery. But no noticable improvement. I may opt for a factory reset if it doesnt resolve in next couple of days.

[SamPro]

That's bad. Please give it sometime before reset. Reset is a pain. I believe it will be resolved.
