r/GalaxyWatch on Reddit: Galaxy Watch Ultra Battery Drastically Decreased since the 8 update
July 29, 2025 -

Idk what's going on, but my battery life has gone from 3 to 4 days, to just barely over a day. Any suggestions would be great.

Ive cleared my cache, have google assistant disabled, auto workout disabled, etc. If I had to disable a bunch of stuff just to get two days of battery life, I would've waited for the watch 8 or wstch 8 classic.

r/GalaxyWatch on Reddit: Galaxy Watch Ultra battery life - 16h
July 26, 2024 -

I seem to only be getting 16-18h of battery life, much shorter than advertised. The battery info shows only ~45% of the battery drained through the listed apps.

Anyone else experiencing this?

UPDATE: Samsung support has been less than helpful (I was offered $27 to not return the watch), so it looks like I'll be returning it since there is no support outside of return and repurchase if you don't have the warranty, even on a 2 day old watch. Waiting a couple weeks for a refund and then a week for the new watch that will also have no support isn't an acceptable option for a $650 watch

r/GalaxyWatch on Reddit: Just picked up the Galaxy Watch Ultra 2025 (Titanium Blue) – first impressions
August 23, 2025 -

So I finally decided to grab the Galaxy Watch Ultra 2025, and I went with the titanium blue version. Honestly, I’m really impressed so far. The finish looks super clean and has that premium vibe without being too flashy. Definitely one of the better-looking smartwatches I’ve owned.

From what I can tell, the biggest actual upgrade this year is the expanded storage, which is great if you keep music, apps, or a lot of data on your watch. Outside of that, the design feels familiar, but honestly, I don’t mind—Samsung didn’t really need to change much because it already looked good.

Overall, it feels sleek, stylish, and solid on the wrist. If you care about both looks and functionality, this one definitely delivers.
