Always connected to mobile bluetooth Tap and raise to wake on. Nfc on gestures on So battery can be improved more but 2 days plus is ideal for me while enjoying the some of the smart watch functions that i care about. Man also if i have alarm specially with vibration and when set to long and i dont wake up fast or keep adding extra 5 minutes nap the vibrations absorb the battery like crazy so started using mobile alarm unless i am not sleeping alone

Galaxy watch ultra is a night and day difference better than OnePlus watch. I owned a OnePlus watch 2 and it feels like a toy compared to my ultra... Also ultra gets me 3 days of usage if you put it in power saving mode when you sleep.
Currently using Samsung Galaxy Ultra, Moto Fit, and Google Pixel Watch 4. Ive used the Samsung the longest and is favored. Pixel is giving it a run for its money though. They both have cellular plans and both work well. The Moto is great at battery, used it a week without putting it on the charger. The other three I am putting on the charger every other day usually. If it wasn't for the domed glass of the Pixel, it would be favored. Knock on wood, it lasts for two years. I do have them tied to their respective company phones too. Workouts are similar however im still testing them out. Out of these three, I would suggest the Samsung. However if you don't have a Samsung, the Pixel.
The Galaxy Watch Ultra would be the best choice. Next would be Galaxy 5 Pro. Although my Pixel Watch 4 gets longer battery life than my Ultra does.
I replaced a Galaxy Watch Ultra with my Fenix 7X Pro and do not regret it in any way.
Im only new to the galaxy watch gang, picked up a galaxy watch ultra (2025 model) last month and im loving it. I upgraded from a fenix 5 which lasts about a week and a half on full battery so my only concern getting the ultra was the battery life but i can honestly say wow, cant believe i didnt upgrade sooner. I can deal with the 2 and a half day battery life cos theres so much more i can do with this watch. I can definitely see how upgrading from the ultra 2024 might not be worth it but if youre rocking a watch 6 or older i recommend it for the battery life if anything
This is exactly the fence I'm on. Just waiting for them to fix the shop page to have the ultra 2024 as a trade in option. If there's no trade in I'll be skipping this year.
Indeed. Skipped. I'll stick with my 2024 Ultra for now. Not even close to worth it this year.
