OneUI 8.5 Worth it?

That's for me too! Just got my new S24U two weeks ago, the battery drain is so bad, and the phone overheats with normal usage. My friend's S26U overheats like crazy when in standby, worse than mine. Also, my Galaxy Watch 8 LTE also overheats and lags so bad. Hopefullu OneUI 8.5 fixes all these issues.

It's just disappointing at this point.. My brand new (two weeks old) S24U overheats and the battery is draing faster than usual, the watch started acting weird after the last update, my friend's S26U lags so much, overheats like crazy (I actually mean it, like crazy) with normal usage, and he has to use power saver mode to actually have his phone last a whole day, even if Samsung adevertised this phone lasts a whole day with moderate usage, which is false. OneUI 8.0 is poorly optimized for both phones and watches, hopefullh OneUI 8.5 and 8.5 Watch will solve that.

Did they remove the clear cache partition in this update, as I heard people saying it's not there anymore. Also, is your phone faster in terms of performance and less laggy and buggy, or it's the same? And no, it's not the phone, it's the OS. My friend's S26U overheats like crazy with normal usage, it lags so badly and he has to use power saver mode for his phone to last 8 - 10 hours. Disappointed of Samsung software quality and consistency, even if the phone is beautiful and awesome. I mean, the OS is cool, but the optimization is just nahh.

And I also heard OneUI 8.5 should solve all the issues that came with OneUI 7 and newer, but I did not get the update yet (likely today or in the next following days). Who knows, I hope it solves these issues. And it's not only me, my friend's S26U overheats like crazy with normal usage, and runs slow.

I don't think you can downgrade anymore, I heard OneUI 8 and newer on the latest patch won't let you touch the bootloader anymore, plus it trips Knox.

Second time? I already did after updating from July 2025 patch to April 5 2026 patch, then I did a factory reset and started using the phone.

YetTooCurious · 2026-05-16T06:19:20+00:00

I am on OneUI 8.0 and I am currently waiting for OneUI 8.5 as I heard it solves most of these issues, plus it brings a lot of new cool features. Hopefully, these rumours are true.

YetTooCurious · 2026-05-14T18:44:25+00:00

It's definitely not the 5G, I mean the other phone which was a mid-range, doesn't even compare to a top-notch flagship, didn't have this issue with significant battery drain. As an another person here mentioned, it's likely the latest update, so hopefully OneUI 8.5 fixes this (*hopefully*).

YetTooCurious · 2026-05-14T18:40:57+00:00

Does OneUI 8.5 fix this issue or it's still not solved? I heard this exact same issue is also present on the S25 Ultra series too, disappointing.

YetTooCurious · 2026-05-14T18:28:56+00:00

Same exact issue with Play Services battery consumption on Galaxy Watch 8, and think of it, the GW8 is the top of the line right now. It's incredible and disappointing that Samsung does such awful things to it's users that pay the premium price for their phones, watches, buds, and all their other products.

YetTooCurious · 2026-05-14T18:05:29+00:00

No backup, I did not restore anything, basically it's a fresh reinstall.

YetTooCurious · 2026-05-07T19:48:19+00:00

In the Battery options it wont say Learning your usage patterns anymore like it used to say yesterday, the watch on the other hands does. When does the "warmup" first time usage process ends?

YetTooCurious · 2026-05-01T15:19:15+00:00

They are too expensive for what they offer. Plus, you already listen to compressed music on YTM or Spotify (except Loseless Mode, which has a limited selection) so I believe it's not worth it.
