Is Your Samsung Phone Slower After Recent One UI Updates? Let's Discuss Real Solutions

[zainali12309]

Many Samsung users have reported performance drops, lag, or battery drain after installing recent One  updates on mid-range and even flagship phones. I’ve personally noticed slow app openings and background freezing on my device after the last update.

I’m starting this discussion to understand:

• Are you facing similar issues on your Samsung device?

• Which model and One  version are you using?

• Have you found any specific solutions (e.g., clearing cache, resetting app preferences, battery settings changes)?

• Any accessories (like power banks or wireless chargers) that started acting up after the update?

This could help many users identify whether the issue is device-specific, update-related, or accessory-related. Let’s help each other by sharing our current problems and what’s worked to fix them.

Thanks in advance to all contributors!

I have galaxy A53 5G and since the update it has been dead slow, internet speed dropped, now only 4g lte not 5g and batter dying very rapidly.

followed all recommendations from Samsung and nothing has worked

S21 5G (normal). Affected right after OneUI 7.0. And much affected,  I started thing about upgrading...

Camera performance decreased + camera app crashed couple of times.

It seems there is less free RAM, as I see that a lot of apps reload itself, so multitasking ability decreased too.

My S25 Ultra won't even open google play store to update my apps which i do everything day sometimes 2x a day. My chrome browser is freezing and today my phone froze and started having a disco light show. I'd love to go back. I don't want to factory reset.

S25. The new actualization made my phone so slow. Apps are freezing. I just got my phone not even a week ago.

Adding on top of my previous report.

Camera app is most frustrating. Delay on _making_ a picture is now common, delays between mode switches. Almost impossible to capture a moment, really frustrating

A25 5G it has become so laggy since the One UI update. Takes ages to change volume and will freeze all the time. I bought this phone new this year and not happy this is happening

A55 and mine has gone sluggish & freezes when multi tasking.
When my phone is locked and I press the button to wake up it takes almost a full second or two to light the screen up. Before it was instant

Samsung S24FE. It got it when one ui 7 came out and that had battery drain. I now have One ui 8 and battery drain is fixed (yay!) But now the phone likes to be sloooooww. Simple tasks like swiping down to navigation bar makes the phone freeze for a solid 10 seconds. Any fixes?
