Samsung Galaxy Watch Active review: Great hardware let down by erratic tracking

Our Samsung Galaxy Watch Active review reveals a fitness smartwatch that has solid hardware but needs better software support for tracking.

Published onNovember 28, 2021

Samsung Galaxy Watch Active

The Tizen-based Samsung Galaxy Watch Active, as a smaller alternative to the big, bulky smartwatches we usually see, is a compelling piece of hardware. It provides a lot of the same features as larger wearables and even adds a few new ones like blood pressure monitoring. The problem is that the activity tracking is way off and is in desperate need of re-tuning before this watch becomes a contender. If you're after a fully-featured smartwatch that's not too chunky or expensive and you're happy to wait for Samsung to recalibrate its tracking, the Galaxy Watch Active might be for you. Just be sure you know the lay of the land where fitness tracking and blood pressure monitoring is concerned if that's why you're buying it. Its battery life is also a little less than stellar, taking too long to charge and not being sufficiently long-lasting for a truly active wearer.

What we like

Lightweight and unobtrusive on the wrist
Clean, unassuming style
Crisp AMOLED display
Supports Samsung Pay via NFC
Tizen software trumps Wear OS

What we don't like

Blood pressure monitoring is a dud
No rotating bezel or LTE version
Very irregular fitness tracking
No MST payments via Samsung Pay
Very slow to charge

Samsung Galaxy Watch Active

The Tizen-based Samsung Galaxy Watch Active, as a smaller alternative to the big, bulky smartwatches we usually see, is a compelling piece of hardware. It provides a lot of the same features as larger wearables and even adds a few new ones like blood pressure monitoring. The problem is that the activity tracking is way off and is in desperate need of re-tuning before this watch becomes a contender. If you're after a fully-featured smartwatch that's not too chunky or expensive and you're happy to wait for Samsung to recalibrate its tracking, the Galaxy Watch Active might be for you. Just be sure you know the lay of the land where fitness tracking and blood pressure monitoring is concerned if that's why you're buying it. Its battery life is also a little less than stellar, taking too long to charge and not being sufficiently long-lasting for a truly active wearer.

Samsung makes some of the best smartwatches around, but they tend to be big, bulky, and aggressively styled. The Galaxy Watch Active is just as well equipped as other Samsung wearables but trades the rugged aesthetic for a more demure style. It also comes at a noticeably smaller price. The Galaxy Watch Active delivers almost everything you’d get in a bigger, more expensive watch at a price most of us can actually justify.

There are, however, a couple of things you need to know before you decide to buy one — like the fact its activity tracking is trash right now. Let’s dive right into our Samsung Galaxy Watch Active review.

New versions are now available: Samsung launched the Galaxy Watch Active 2 quite a while ago, with an improved display and battery. If you want a more mainstream smartwatch experience, you can also check out the Galaxy Watch 4 series.
About this Samsung Galaxy Watch Active review: I've been using the Galaxy Watch Active for two weeks. It's running One UI version 1.0 on Tizen OS version and software version R500XXU1BSB7, paired to a Pixel 3 over Bluetooth.

The big picture

The Galaxy Watch Active is not Samsung’s first foray into the fitness smartwatch category: the original Gear Sport arrived almost a year and a half ago. While the Samsung Galaxy Watch Active could easily be considered a Gear Sport 2, Samsung instead positions it as the sporty version of its recent Galaxy Watch range.

Given its $199 price point, the Galaxy Watch Active is positioned alongside several excellent fitness trackers. Samsung’s goal is clearly to snag part of that target market with a comparably-priced smartwatch that does a bit more than your average fitness tracker. It’s also a competitively priced option for regular smartwatch buyers who don’t like the usual bulky designs or have slimmer wrists. Unfortunately for Samsung, while its watch might do more than your average fitness tracker, it certainly doesn’t track activity better.

Design and display

Samsung Galaxy Watch Active default watch face
  • 40mm watch case (one size only)
  • 1.1-inch AMOLED display (360 x 360 pixels)
  • 20mm silicone watch strap (two sizes included)
  • Black, silver, rose gold, green

Even though the Galaxy Watch Active’s 40mm housing is only marginally smaller than the 42mm version of the Galaxy Watch, the difference in bulk is noticeable. Besides the difference in style, the Watch Active is also far lighter at just 25 grams compared to the smaller Galaxy Watch’s 49 grams. If you’ve ever tried exercising with a normal-sized smartwatch, you’ll know this is a big plus.

The lightness and smallness of the Samsung Galaxy Watch Active mean it’s far less likely to get in the way of your workout. Its near-flush buttons also mean they won’t get caught on things while you work out or dig into the back of your wrist when doing shoulder presses or loaded squats.

Despite its diminutive size, the Galaxy Watch Active is plenty rugged enough to survive an active lifestyle. The small circular display is coated with a layer of Gorilla Glass 3 (but no Corning DX+). It’s water-resistant up to 5ATM and certified MIL-STD-810G compliant. I dropped it on day one and couldn’t see where it hit the ground, nor did it pick up any scratches during a couple weeks of use. Activities during this time included swimming, cycling, running, gym workouts, and yoga on top of daily wear and tear, and several keyboard commando skirmishes.

The screen is great: vibrant and crisp, a necessity on a display this size. I found the auto-brightness to be quite responsive outdoors, but unless you’re looking directly at the Watch Active, the glare tends to obfuscate the display. Keep this in mind if you like to glance at notifications or activity tracking while cycling, for example. It’s okay for running when you can lift your arm right up to your face, but this is not always possible during activities you may want to track.

If you’re coming from a larger-screened wearable, be aware that its 1.1-inch display might feel a little pokey. For reference, the Galaxy Watch Active’s 28mm screen is a half-centimeter smaller in diameter than the larger Galaxy Watch and offers just 72% of the display area. The lack of a rotating bezel here is noticeable because it means you’ll have to swipe and tap your way around the tiny UI elements.

There is a microphone on the Watch Active but no speaker, so while you can answer or initiate calls with it, you’ll need a paired phone to actually hear your interlocutor. Likewise, you can trigger Bixby queries via the watch but only get text responses on it unless you have a pair of wireless headphones paired (I’d suggest maxing out the volume on the watch and just controlling it on your headphones). Bixby is perfectly fine for general voice searches like the weather but will only be really useful if you also have a Samsung Galaxy smartphone (as that’s where Bixby’s strengths lie).

The silicon watch strap the Samsung Galaxy Watch Active comes with is perfectly serviceable and closes with a traditional watch buckle. The excess strap tucks underneath the strap to keep it out of the way. I like this clasping mechanism and tidy approach to the leftover strap. There’s a whole host of optional bands you can swap out thanks to the standard 20mm strap sizing. There’s also a longer strap (the bit with the holes in it) in the box if you have larger wrists.

Smartwatch features

  • Smartphone notifications

In typical Samsung fashion, the Watch Active has plenty to offer in terms of feature set and customization. It comes with a decent selection of watch faces to choose from, and you can download more from the Galaxy Store (note: it runs Tizen 4.0, not Wear OS, which is just fine by me). All watch faces can be customized to your liking, so you can change colors, backgrounds, and UI elements as you see fit.

The two buttons on the side of the Watch Active are straightforward: the top one takes you back a step, and the bottom summons the app carousel. By default, a double press of the bottom button fires up Bixby, but as with most other things on this watch, you can customize this. I set it to display the world clock, but you can change it to a shortcut for pretty much anything on the Galaxy Watch Active.

Swiping right on the UI accesses your notifications, which can be expanded beyond the summary view by tapping them. Doing so also allows you to respond, either using emoji, a tiny T-9 keyboard, voice dictation, or short canned answers like “on my way” and “talk to you later.” I found notifications on the Watch Active to be super reliable and prompt, and responding to them even from such a small wearable was as good an experience as can be expected.

Swiping to the left cycles through fairly standard customizable screens, including an activity dashboard, recent apps, heart rate monitor, calendar, contacts, weather, and music controls. There’s also a bunch of Samsung Health screens you can add here, including shortcuts to your favorite activity tracking, fitness challenges, leaderboards, sleep data, weight management, and monitoring of your caffeine and water intake.

Swiping down from anywhere in the UI reveals the quick settings, which include:

  • Goodnight mode
  • Bluetooth shortcut
  • Silent/vibrate toggle
  • Do not disturb mode
  • Always-on display
  • Screen brightness
  • Theater mode
  • Settings
  • Power saving mode
  • Airplane mode
  • Water lock mode
  • Wi-Fi
  • GPS
  • Battery shortcut
  • Find my phone

I won’t go into all these options as you can tell what they all do by their names. Suffice it to say, the Samsung Galaxy Watch Active certainly doesn’t feel like it lacks in features, other than perhaps an LTE variant or a larger version. Everything on the watch feels fully baked, too, with none of the glitchy or half-assed experiences you might be used to on Wear OS. Navigating long lists certainly isn’t as easy as it is with a rotating bezel, but the essential software and smartwatch features on the Watch Active are pretty solid.

The Watch Active has NFC so that you can use Samsung Pay at newer contactless terminals, but Samsung removed the MST chip you’ll find in something bulkier like the Gear S3 Frontier. That means you can’t use the Galaxy Watch Active at older magnetic stripe terminals. This may not matter too much depending on where you live, but be advised that Samsung Pay on the Watch Active doesn’t have the same widespread support as your Samsung phone.

Fitness and health tracking

Samsung Galaxy Watch Active watchface 1
  • Blood pressure monitoring
  • Auto-detect fitness tracking (seven activities)
  • User-initiated fitness tracking (39 activities)
  • Sleep tracking
  • Heart rate monitoring
  • Stress monitoring
  • Built-in GPS

The one area in which the Galaxy Watch Active doesn’t score top marks is, ironically enough, health and fitness tracking. The arrival of blood pressure monitoring to a mainstream and affordable smartwatch was big news, especially given that the only other option right now is the $499 Omron HeartGuide. The problem is the Samsung Galaxy Watch Active doesn’t really deliver on the promise (at least, yet). It’s important to note it’s not FDA-approved like the Omron HeartGuide either.

Blood pressure monitoring on the Samsung Galaxy Watch Active works via a companion app you’ll have to install separately called My BP Lab, developed with the University of California, San Francisco (UCSF).

The app is not great. It’s unstable, frequently crashes, and, if the reviews on the Play Store are to be believed, doesn’t even take accurate blood pressure readings (I, unfortunately, didn’t have access to a sphygmomanometer to compare). The My BP Lab app only works with the Samsung Galaxy S9/S9 Plus, S10 and S10 Plus, and the Note 9, and is currently available in beta form once you sign up in the U.S., Canada, Australia, Germany, and Singapore. It’s also worth noting there’s a good chance the app will never be pre-installed on all Watch Active models going forward.

Reconsider buying the Galaxy Watch Active if blood pressure monitoring is what you're after.

If blood pressure monitoring is why you want the Galaxy Watch Active, I’d advise you to reconsider. I’ve reached out to Samsung to ask if it has plans for a Samsung Health-based solution rather than My BP Lab, but I have not received a response. In time, blood pressure monitoring may become an integral part of the Galaxy Watch’s otherwise impressive fitness toolbox, but for now, it’s a hard pass.

The rest of the health tracking on the Samsung Galaxy Watch Active is up for debate. I found its step count usually matched other wearables I have reasonably closely. Still, it didn’t always agree with what Samsung Health said (even after freshly syncing) or what my phone’s step counter was reporting via Google Fit. Admittedly, when all your gadgets are reporting different results, it’s not easy to pin the blame on any of them, so I can’t say this is definitely Samsung doing something wrong — at least regarding step count.

Samsung Galaxy Watch Active sensors

Heart-rate monitoring was another issue, with the Watch Active occasionally producing significantly different results to other wearables I own. Comparing it to the HUAWEI Watch GT, it was frequently off by a wide margin. While typing this with both watches on either wrist, I get a 60bpm reading on the Watch Active and 77bpm on the HUAWEI Watch GT — that’s a huge discrepancy of more than 25%.

While the Watch GT may be over-reporting, its reading stays relatively stable and fluctuates in a manner you’d expect. The Galaxy Watch Active, on the other hand, constantly fluctuates, with a resting rate that can rapidly change by 15-20bpm, all while doing the same thing. These erratic changes make me confident that it’s the culprit here. Under- or over-reporting heart rate is a real cause for concern, especially on a fitness tracker where accurate heart-rate monitoring is essential for activity target zones.

Floor tracking on the Watch Active is atrocious. I live in a two-story home, and as I write this, I know I’ve been up and down the stairs at least a dozen times, and yet the Galaxy Watch Active says I’ve only done one floor all day. The activity auto-tracking does kick in pretty reliably when walking or running, but the results it records aren’t there yet. The Watch Active can auto-detect seven exercises with a further 39 able to be tracked by manually initiating them.

Samsung Galaxy Watch Active stress monitoring

Sleep tracking is equally problematic. The Watch Active doesn’t always seem to know the difference between chilling on the couch and actually being asleep. So you’ll occasionally get sleep tracking that reports a two-hour sleep followed by a couple of hours awake and then a longer sleep, when really you were just watching a movie before getting up and doing other stuff before bed. Once your sleep has been logged to Samsung Health, you can’t edit it either.

I could go on with multiple other health tracking quibbles, but I’m sure the point is clear. As it stands right now, the Samsung Galaxy Watch Active is an excellent piece of hardware let down by lousy tracking calibration. The good news is that this can likely be fixed with a software update, but I’d recommend you wait for that to arrive before investing in this watch. We’ll update this review if and when these issues are addressed.

Samsung Health app

The Samsung Health app is a vast, sprawling app with more nooks and crannies for the data-obsessed than you can poke a stick at. I won’t go into it in too much detail here as it is simply too massive to do justice, but rest assured, you can while away many hours delving into all the data it stores. As mentioned above, though, much of that data is of dubious accuracy, so don’t invest too much in what it’s telling you.

If you’re already familiar with Samsung Health, you’ll be well versed in where to go, how to get the most out of it, and the best way to set the various options up. However, if you’re new to Samsung’s fitness app, expect a bit of a learning curve as you find your way around its many menus, options, and settings.

You’ll need to install a dizzying array of apps at startup: the Galaxy Wearable app, the Galaxy Watch Active Plugin, Samsung Accessory Service, and then Samsung Health and Samsung Pay if you don’t already have them.

The Wearable app lets you control everything on the watch with your phone and enables you to transfer content like music and images. The app can also set up an SOS transmission to share your location with selected contacts in an emergency by quickly pressing the bottom button three times.

Samsung Galaxy Watch Active: Performance and battery life

  • 4GB internal storage
  • 0.75GB of RAM
  • 230mAh battery

The Watch Active performs well, and I had no noticeable issues with lag, stuttering, or crashes, barring the Plugin crashing when I tried to sync music (that was likely due to the Android Q developer preview, not the watch). Speaking of music, if you want to load your tunes onto the Watch Active’s internal storage, just be aware about half of it will already be used out of the box.

The Galaxy Watch’s battery is admittedly small but is only a little smaller than the small Galaxy Watch. Samsung promises 45 hours of battery life which is probably true if you disable pretty much everything. If you’re regularly tracking activities (as I would assume you would), you’ll be able to get through a day. If you’re streaming music that’ll drop to less than a day, use GPS and it’s half a day — you get the idea.

I found a day’s usage was pretty standard with an average mix of notifications, music, activity tracking, and interactions with notifications. This is neither better nor worse than most other smartwatches, but better battery life would have been appreciated for a watch designed specifically for an active lifestyle.

What’s perhaps worse is the extremely slow charging via the included wireless puck. Instead of using pogo pins, Samsung opted for wireless charging here. It’s painfully slow. The 230mAh battery takes almost two hours to charge, which is a horrendously long time for a watch you might just want to juice up quickly before you duck out for a run. You can wirelessly charge it on the go with the new S10 family, but it’ll take even longer to charge that way.

Samsung Galaxy Watch Active: Pricing and final thoughts

At $199, the Galaxy Watch Active is priced very competitively. As far as hardware performance goes, it’s up there, barring the battery and charging issues just mentioned. Where the Galaxy Watch Active falls, though, putting it squarely in the do-not-buy territory — is fitness tracking. Fortunately, this is something Samsung can absolutely fix and will hopefully do so soon. I’ve had a great experience with other Samsung wearables in the past, so I know Samsung can make amends.

Despite the 'Active' name, you shouldn't buy the Galaxy Watch Active if you need accurate fitness or health tracking.

If the actual data recorded by the Watch Active is not the reason you’re buying it, then go ahead — it’s likely a sound investment (especially seeing there are so many open box discounts already due to the number of returns retailers are seeing).

If you want a wearable for notifications, music, something to prompt you to move or relax, and tell you the time, then yeah, the Galaxy Watch Active is great. But add blood pressure monitoring, sleep tracking, heart-rate monitoring, step or floor count to that list of needs, and the Watch Active is simply not a good buy right now.


Looking for an alternative? The Fitbit Ionic has a similar feature set, price point, and isn’t bad at fitness tracking. The Garmin vivoactive 3 Music is also a great GPS running smartwatch.
