Smartwatches and fitness trackers beta · Samsung
Owners wear the Galaxy Watch 7 day and night for sleep and health tracking, and they fit charging around it, usually a top-up before bed or a charge every couple of days.
Owners are divided on battery life, but some are satisfied with it. One owner of the 44mm Wi-Fi model charges every two days with all health features on, and another got about 44 hours a charge with always-on display and continuous heart rate and stress tracking running.
Owners are divided on battery life, and some find it drains too fast. One owner who charges before bed watched it fall from the mid-70s to about half in six hours. Another owner gave up features like raise to wake to make a charge last.
The Galaxy Watch7 is Samsung's round smartwatch from 2024. It comes in 40mm and 44mm sizes and runs Wear OS. It is for Android phone owners who want fitness, sleep and heart tracking plus phone alerts on the wrist.

From the maker's spec page, checked October 8, 2026. A blank row means the maker does not state it.
You will probably charge it every night, or about every day and a half if you keep the screen off when you aren't using it. 5ATM and IP68 mean it is fine for swimming in a pool and in the shower, but it isn't made for diving. Dual-frequency GPS tracks runs more accurately near tall buildings and trees, and you don't need your phone with you. It does not work with iPhones.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
Once it settles in, the watch becomes part of the bedtime routine. Owners charge it in the evening so it can record sleep overnight, and one owner considers waking up with roughly 70 to 80 percent left normal. Health tracking, including heart rate and stress, runs in the background all day without much attention.
The adjustment is mostly about settings. Some owners turn off always-on display or raise to wake and wake the screen with a button or a tap instead, trading convenience for longer battery. One owner found that battery saver and sleep mode changed the raise to wake and always-on display settings when they switched on or off automatically, so it took some attention to keep the watch set up the way they wanted.
Day to day, the main problems in these accounts are software glitches, not hardware failures. A few owners describe the watch misbehaving until it was reset. One found that opening settings from the status bar brought it back to normal without a full restart. Another, with the watch snug and the sensors clean, put an inaccurate reading down to a software bug. Separately, two owners say their watch failed after being used in water (one after a single swim, one after one dive), and one of them says Samsung rejected the warranty claim. These support and software accounts are too few to draw a firm conclusion from.
Long-term accounts are thin. Most of what owners describe is everyday battery behaviour and individual glitches, and there is little here about how the battery, sensors or water resistance hold up after a year or more of use.
Parts named in the 3 accounts that describe a failure
From 9 owner accounts that said how long they have had it. Own one? Add how long yours has lasted.
Nothing with a clear majority yet. Owners who raised these subjects were split, or too few to judge.
Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
22 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 9 owner accounts here that gave a duration, 3 described a failure. Parts named most: battery, other, display settings (software).
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.
