Samsung Galaxy Watch 4: One Year Later, Still Worth It?

Samsung's Galaxy Watch 4 launched to a lot of fanfare, largely because of one decision: ditching Tizen in favour of Wear OS. Now that it has been on the market for several years, this Samsung Galaxy Watch 4 review revisits what actually holds up, based on the specifications, the update history, and what owners and reviewers have consistently reported since.

Reports suggest it has aged well, appealing even to people who would normally describe themselves as mechanical watch purists. That crossover appeal says something about how well Samsung executed this particular pivot, and it's worth unpacking why.

The Wear OS Gamble That Paid Off

Samsung abandoning Tizen for Wear OS felt huge at the time. Tizen was clunky, sure, but it was theirs. Switching to Google's platform meant losing control, but gaining the entire Play Store ecosystem: apps that actually work, and third-party watch faces that don't look like they were designed in 2012.

That trade appears to have paid off. Owners commonly report that Strava now runs properly, Spotify integration works without the frustrations that plagued earlier Tizen apps, and Google Maps on the wrist is genuinely useful for navigation on foot or by bike, not just a gimmick.

The interface is widely regarded as smoother than any previous Tizen watch, with swipe navigation described as natural once you're used to it. The rotating bezel is absent on the standard Watch 4, reserved instead for the pricier Classic model, but reviewers generally find that touch and swipe navigation works fine after an adjustment period, even if a physical dial is missed at first.

Body Composition: Gimmick or Game Changer?

The BioActive Sensor was Samsung's big play here: body composition analysis on your wrist, covering skeletal muscle mass, body fat percentage and body water. It sounds like marketing nonsense at first glance.

Except it isn't entirely useless. Owners who have compared its readings against dedicated body composition scanners have reported that the watch tracks reasonably close on body fat percentage, with muscle mass readings running a little optimistic, as these sensors often do. Consistency over time seems to be the more useful takeaway than trusting any single reading in isolation.

For most people, this isn't a feature used daily so much as an occasional check-in tool, useful for spotting broad trends rather than obsessing over exact numbers. It's a nice-to-have rather than a must-have, but the reported accuracy is better than the gimmicky reputation body composition tracking often carries elsewhere.

Heart rate tracking during workouts is widely reported to be solid, with owners comparing it favourably to dedicated chest straps, generally landing within a few beats per minute. Blood oxygen readings are harder to verify without medical-grade equipment for comparison, but the ECG function is reported to work well for those in supported regions willing to work through Samsung Health's setup process.

Size and Wearability

The 44mm case is reported to suit larger wrists comfortably without feeling chunky, while the 40mm option is aimed at smaller wrists. The Super AMOLED display is consistently praised as gorgeous, with vivid colours and text that stays sharp even in direct sunlight, and reviewers note that moderate brightness settings remain perfectly readable in most everyday conditions.

Battery life is where things get more complicated. Samsung claims up to 40 hours. In practice, owners commonly report closer to a day and a half with moderate use, meaning the always-on display disabled, periodic heart rate monitoring, one tracked workout a day and notifications enabled. Enabling always-on display and using GPS heavily tends to push charging back to every single evening.

For many, that's a manageable routine, folding a charge into a morning shower or getting-ready window. A full charge is reported to take around 90 minutes. But anyone wanting multi-day battery life comparable to a Garmin should look elsewhere. This watch trades longevity for features and screen quality.

Sleep tracking works, though wearing any smartwatch to bed comes down to personal preference, and not everyone finds it comfortable. Where it is used, the data is generally reported as reasonable, correctly picking up overnight wake events, and sleep stage tracking is included. As with all consumer wrist-based sleep tracking, though, this remains something closer to an educated guess than a clinical measurement.

The Frustrations

No product is perfect, and the Watch 4 has quirks worth flagging.

First, several features are Samsung-only. Body composition, ECG and blood pressure (in supported markets) all require a Samsung phone, locking out anyone on a different Android device from half the health suite. That's a frustrating limitation. If Samsung is going to pivot to Wear OS and embrace Google's ecosystem, locking key features behind its own hardware undercuts the point somewhat.

Second, app quality is inconsistent. The Play Store selection is a clear step up from Tizen, but Wear OS apps remain hit-or-miss. Some are excellent, others look like they were ported from 2015 Android and never touched again. Google's own apps are dependable, but third-party offerings can be a lottery.

Third, the lack of a rotating bezel is felt more than it might first appear. Scrolling through long lists with swipes isn't as satisfying or precise as a physical dial. The Watch 4 Classic exists for this reason, but it's bigger and more expensive, a trade-off worth weighing depending on how much a physical bezel matters to you.

Fourth, durability is a recurring concern. The aluminium case is commonly reported to scratch easily, with scuffs appearing on the bezel even from light everyday use. The glass, Gorilla Glass DX+, tends to hold up rather better than the case itself. Anyone precious about cosmetics will likely want a case or bezel protector.

Workout Tracking

The Galaxy Watch 4 is commonly used for running, cycling, swimming (it carries a 5ATM rating, suitable for pool swimming) and gym sessions. GPS lock is reported to be fast, typically under 10 seconds outdoors, with route tracking accurate enough for casual and recreational training rather than serious ultra-distance work.

Workout auto-detection is generally described as okay rather than great, sometimes prompting a little later than ideal, but working more often than not. Swimming tracking is basic but functional, and lap counting is reported to be reasonably accurate.

For serious athletes, a Garmin or a Polar remains the better fit. The Galaxy Watch 4 suits people who work out regularly but don't need VO2 max trends and lactate threshold analysis. It's good enough, and for most people that's fine.

A Year On, Prices Have Dropped

This is where the Watch 4 gets genuinely interesting. At launch, it competed directly with premium smartwatches. Now, it can be found on sale for significantly less, especially with some patience or seasonal timing.

At current street prices, it looks like a bargain. The hardware remains competitive, Wear OS is mature and stable, and the watch has received major updates since launch, and Samsung has kept up with updates reasonably well. Buyers are getting most of what the Watch 5 offers for considerably less money.

For anyone on a Samsung phone who wants the full suite of health features, it's a straightforward recommendation at current prices. Even on a non-Samsung Android phone, it remains worth considering for the app ecosystem and display quality, provided multi-day battery isn't a priority.

Who Should Buy This?

This suits anyone who wants a smartwatch that looks good, runs smoothly, and delivers genuinely useful health data without Garmin-level pricing, and who's comfortable charging daily or every other day. It's built for Google's app ecosystem rather than a walled garden.

It's probably not the right choice for anyone wanting week-long battery life, iPhone users (compatibility is limited and clunky), or anyone needing rugged outdoor tracking features. It's also worth skipping if vendor lock-in is a dealbreaker and you're not on Samsung hardware.

The Verdict

The Galaxy Watch 4 is easy to underestimate, particularly for anyone drawn to mechanical watches for their character. But the evidence suggests it earns its keep for daily life, workouts, and the moments where notifications on the wrist genuinely help rather than distract, without needing to replace anything with more soul.

Samsung took a risk pivoting to Wear OS, and that risk appears to have paid off. The Watch 4 comes across as the first Samsung smartwatch that doesn't compromise heavily on either features or usability. It's good at being a smartwatch, which sounds obvious but hasn't always been true of Samsung's past efforts.

Now that prices have settled, it stands as one of the better value propositions in the smartwatch market. Not perfect. Never perfect. But very good at what it does, and for most buyers, that's enough.
