Battery draining fast after UI7 update

[Ballingdon]

Why is the battery life so much shorter now on my S22Ultra after updating to UI 7?

My usage hasn't changed but battery is discharging much more rapidly.

Have switched off anything unnecessary and even wiped cache.

Same issue on S22+ settings all set to off or deep sleep. 24hrs / charge on UI 6, 16hrs / on UI 7. Hopefully after a few days the battery life will normalize

Tried but got
USSD Code running,
(then after 2-3 seconds)
UNKNOWN APPLICATION.
Edit:-
FIXED this by turning off
AUTO BLOCKER in Settings ->Security and Privacy

Thanks, tried that, took about 15 mins and I'm now watching over next week or so.

I'm having the same issue on my phone.  I hope they fix this soon.

I have the same issue.Before the update i was charging my phone at 80% and was OK for full day.Now after the update I charge it until 85% and I have to charge it 2 and sometimes 3 times per day.Not happy at all.They have to find  solution...or we have.

That does not work over time. IV tried this, Samsung will ignore this setting and force updates on you matter what, especially large UI updates.

I am using the Samsung S-23 Ultra and facing the same battery drain issue after updating to Android 15 based One UI 7.

Having the same problem here with my S23 Ultra! Battery drains too fast, and it was changed a couple of months ago, so it's practically brand new, but since the update, it's terrible!!!
