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!

Currently using the S24 Plus OneUi 7. Haven't really noticed any performance drop or battery drain . It's been functioning just as before.

S25U- currently on ui8 beta. Zero performance issues as of now.

Biggest help for battery was good guardians

Hi! Welcome to the Samsung Members community!

I'd suggest making a post with the specifics of what you particularly dislike. The update can't be reverted, but hopefully, you can gain helpful information to better your experience. There are already lots of posts, too, so there may already be answers out there.

I always follow the same process.

1) install new update
2) reboot phone into boot menu and perform a cache reset.
3) go into google play store and update all installed apps. Often there are 20 or more apps needing updating after a new UI update.
4) the same with Galaxy store.
5) use good guardians 'Galaxy App booster'. Allow optimisation.

Over the next day or two I observe the battery usage to ensure no unexpected apps are draining battery quicker than normal.

USUALLY by following these steps keeps the phone software healthy and up to date.

...and if there are any issues then I would backup all my important information for contacts messages and photos etc... usually to google photos and my google account.

I would then do a complete factory reset of the phone with the new UI update.

When performing 'upgrades', then it should be a successful process and ok to use, although it is important to realise that this then is an updated software of oneui6... rather than a complete new installation of the new software.

Often a brand new installation of the new UI software will give a much better experience after the update.

When doing this then I would recommend NOT using smartswitch utility, but to install everything from the beginning again. This can be time consuming to install all apps from the stores again, but may well give a cleaner phone and one that is more optimised. Also any app in-compatibilities that may occur (and the usual reason for slow down and battery drain) will not occur.

Following the One UI7 update on my S24U, I've observed a significant decrease in battery life and increased device temperature during gameplay. Have other users experienced similar issues?

I feel like background apps have been doing the battery issue
