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

Galaxy Watch Ultra battery life - Samsung Community
August 15, 2024 - As it was a much bigger battery I expected much better life. I've been disappointed so far, getting barely 3 days between charges. However, after the update the other day, I'm pleased to now be getting over 4 days!

galaxy watch ultra battery life after update to Ui8 - Samsung Community
August 6, 2025 - I have the 7 ultra and maybe the first few days the battery life was lower, probably due to me using it more to adjust tiles and settings, it now seems about the same as before with between 3 and 3.5 day's on a full charge .

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: Ultra battery life 😬
July 22, 2024 -

Well, I got the watch Saturday and have been using it since then. I understand it's still in battery training mode, trying to get patterns and such but it's been quite bad so far. Much worse than the 6 classic and even 5 pro... Less than 15 hours with 85% battery is bad bad...I went for a run this morning, started with about 75% and ended at 9%. Using LTE for Spotify and Bluetooth connected to my buds 3 pros. I know lte will increase drain but my run was just short of 2 hours, 13.1 miles, I had expected it to hold up better. If things don't get better I may have to return it for a Garmin. I need to be able to have it last for an entire marathon and as of now, I don't see that happening.

The Galaxy Watch Ultra isn’t living up to its name: Here’s how Samsung can fix that - PhoneArena
4 days ago - With GPS, health tracking, and notifications enabled, the Galaxy Watch Ultra settles into a predictable two-day rhythm. That’s acceptable for a smartwatch, but we have rivals from Huawei or OnePlus that show us it could be much better. The Galaxy Watch Ultra 2 doesn’t need a week-long battery life (we have to be realistic here).
