S22 - One UI 7 update - May 2025 killed my battery life

[Members_KHZmX8c]

Since I have updated to the latest software on my S22 5G, battery life is horrible. Can't get past 2pm without having to charge again. I am not a heavy user of high processing power apps. Where and how is the best way to inform Samsung?

Silly work arounds and widgets do not and will not help repair the battery issue. Prior to the update, I ran all day and went to sleep with 30-40% battery remaining at night.

First, turn off Auto Blocker then follow these instructions EXACTLY as written

Using the Samsung Phone App (not the Google one)

Dial *#9900# then scroll down to battery stats reset. Click then restart your phone.

Turn Auto Blocker back on

Restart device

Wait 14 days for battery optimisation to complete.

I have the Samsung Galaxy S21 5G but still haven't had the software update yet

I'm having the exact same issue, googling "s22 one UI 7 update killed my battery life" brought me to your post. For future readers, I think you posted 10 hours prior to me arriving here. My battery life has been getting noticably worse each day since the update but dramatically worse this week and today triggered me to search for answers.

There is NO solution in the forum. The battery drain on One UI 7 / Android 15 must be fixed by Samsung / Google and not by useless workarounds!

I just got my update for the S22 yesterday. It's a disgrace that they're still shipping such a broken system.

[Piper123]

Well I'm glad you know better as I've posted the solutions myself dozens of times.

But don't worry, there are no solutions as you've said.
