Smartwatches and fitness trackers beta · Samsung
Owners wear it through swims, saunas and mountain-bike falls and keep it as a capable Wear OS watch, accepting battery life they argue over and charging they find slow.
Owners are divided on battery life. Some get a steady couple of days with cellular and lift to wake always on and call it fine for daily use, while others say a bigger battery is the one thing the watch is missing.
Slow charging is a clear complaint. Owners describe long waits to top it up, and one notes the watch accepts only about 10 watts of input, so a more powerful charger does not speed it up.
The Galaxy Watch Ultra is Samsung's tough, titanium-cased smartwatch for outdoor sports, diving and long days away from a charger. Samsung's US store currently sells two models: the newer Galaxy Watch Ultra2 (2026) and the older Galaxy Watch Ultra (2025). Both come in one 47mm size with LTE, and both are made for people with Android phones who want a sturdier watch with a longer battery life than the regular Galaxy Watch.
Several models, specs differ.
The Ultra2 costs $699.99 and the older Ultra (2025) costs $649.99. Both are 47mm with LTE. Samsung says the Ultra2 has a 35% bigger battery (800 mAh) that lasts up to 60 hours with the always-on screen, and it is the first Galaxy Watch with fast charging (40% in 30 minutes). Samsung also says the Ultra2 has a newer Snapdragon chip and a slimmer case. The Ultra2 comes in Titanium Silver and Titanium Gray. The older Ultra comes in Titanium Blue, Silver, Gray and White.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
What keeps people happy is how much it can be put through. One owner has taken it into pools, lakes, the ocean and saunas and onto a mountain bike. Another came from an Apple Watch Ultra, found the two nearly identical and found this one's GPS more accurate on runs. A few owners say heart rate matches a chest strap closely, though it is slower to catch sudden changes during weightlifting.
The daily routine bends around charging. Owners who track sleep keep the watch on overnight, so topping it up has to happen during the day, for example at a desk while working. Opinions on sleep tracking are divided. One owner finds it accurate as long as the strap is snug. Others found it leaning toward deep sleep compared with an Apple Watch and an Oura ring, and one turned it off altogether. Another owner hands sleep tracking to a Galaxy Ring instead.
The hardware itself gets a good account. An owner who has had it since launch has been through water, heat and several bike crashes without a single problem. Heart readings are described as consistent, and cellular, lift to wake and health tracking simply keep working. The weak points are battery capacity and charging time, and owners work around them by charging during the day, not by finding a fix. Sleep readings depend on fit, so owners who keep using sleep tracking wear the watch tighter.
Long-term accounts are thin. Only one owner describes extended ownership in any detail. Most of the rest are comparisons with other watches, and several are about the Ultra 2 instead of the original, so there is not enough here to say how the battery or the hardware ages over years.
From 12 owner accounts that said how long they have had it. Own one? Add how long yours has lasted.
Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
19 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
The same owner, asked again at each point. Fills in as owners answer.
Two questions: how long you have had it, and anything you would like to say about it. Then we ask again as it ages. This helps our mission.

Among the 12 owner accounts here that gave a duration, 2 described a failure. Parts named most: water damage, internals (corrosion).
Before you buy one used, ask the seller: how old it is, whether it was ever repaired and by whom, and whether any of the parts above have been replaced. Ask to see it run. A receipt tells you the warranty start date; most makers honour the term only for the first owner.
