Samsung Galaxy Watch 4 and Galaxy Watch 4 Classic: Everything you need to know
With its new flagship smartwatches, the Galaxy Watch 4 and Galaxy Watch 4 Classic, Samsung takes a big leap into the unknown. There are plenty of hardware upgrades and design refinements to look forward to. But the big news here is that Samsung canned its familiar Tizen operating system in favor of the new Wear OS it co-developed with Google. We considered its predecessor one of the best smartwatches for Android users, and Samsung’s latest are primed to take its place on the list. Here’s everything you need to know about the Samsung Galaxy Watch 4 and Galaxy Watch 4 Classic.
Samsung Galaxy Watch 4 and Galaxy Watch 4 Classic at a glance
Samsung launched two smartwatches, the Samsung Galaxy Watch 4 and the Samsung Galaxy Watch 4 Classic, on August 11, 2021. For the most part, the two feature similar specs and design cues but are built for different users.
The Samsung Galaxy Watch 4 is the spiritual successor to the Galaxy Watch Active 2. (It just has a nicer name this time.) It’s the sporty one, comes in better colorways, and has an overall smaller form factor. The Samsung Galaxy Watch 4 Classic is the direct successor to last year’s Galaxy Watch 3. It’s bigger, classier, and simply offers more.

The physical rotating bezel — which we adore — returns on the Galaxy Watch 4 Classic, while the vanilla Galaxy Watch 4 has a touch-enabled bezel similar to that of the Active 2.
Both devices have bigger, brighter displays than before, offer longer battery life, and have new health features that aim to give you a more holistic view of your current health conditions. Again, these are also the first two devices with the new Wear OS on board.
There are a few different versions to choose from. The Galaxy Watch 4 is available in two different sizes — 40mm and 44mm. On the other hand, you’ll get 42mm and 46mm variants of the Galaxy Watch 4 Classic. There’s a $30 difference between the two size versions in both cases. You will also have the choice between Bluetooth-only or LTE variants, with another $30 surcharge for the latter.
Are the Galaxy Watch 4 or Galaxy Watch 4 Classic worth buying?
Yes, absolutely. If you’re looking for the best smartwatch you can buy that isn’t made by Apple, the Galaxy Watch 4 or the Galaxy Watch 4 Classic are it. However, with two distinct smartwatches this time around, users have a choice to make.
The Watch 4 and Watch 4 Classic are quite similar. The Galaxy Watch 4 is smaller, thinner, lighter, and uses a capacitive touch-based virtual rotating panel instead of the physical rotating bezel you get with the Classic. You’ll still get the same display sizes across the board, though. You’ll also get the same set of features, similar internal hardware, and an identical software experience. These are some of the most fully featured smartwatches you can get.

Adding to the breadth of fitness tracking and health monitoring features available, the Galaxy Watch 4 series also comes with an optical heart rate sensor (PPG), electrocardiogram (ECG), and bioelectrical impedance (BIA) sensor. There’s an unfortunate catch here in that you’ll need a Samsung phone to use some of these new features (more on this later), but we’ll hopefully see better support down the line.
The Galaxy Watch 4 and Galaxy Watch 4 Classic are cheaper than what their predecessors cost at launch. However, depending on the size and connectivity options, they can get pricey. The regular Watch 4 starts at $249 and goes up to $329, while the Watch 4 Classic will set you back between $349 and $429. These aren’t the most expensive smartwatches around by any means, though, and it’s great to see them priced to compete in an increasingly packed field.
What reviewers are saying about the Galaxy Watch 4 and Watch 4 Classic
In his review, Android Authority’s own Jimmy Westenberg says, “all of the smartwatch features work well, the fitness features are abundant and improved, and both devices can be customized to your particular size and style.” He adds that while the Galaxy Watch 4 series is in a league of its own in the Wear OS ecosystem, it isn’t quite perfect.
There aren’t too many issues with the watches, but the lack of device support is disappointing, with features like ECG readings and blood pressure monitoring only available with Samsung phones. The software experience is good, but it’s more Samsung than Google in this case, so it’ll be interesting to see how other Wear OS watchmakers adapt to the new software. It’s also still early stages, so plenty of software features are still to come, the most glaring being the lack of the Google Assistant. However, despite some quibbles, he concludes that “the Samsung Galaxy Watch 4 is a fantastic smartwatch that I wouldn’t hesitate to recommend to any Android user.”
What other reviewers around the web are saying about the Samsung Galaxy Watch 4 and Watch 4 Classic
- Tech Radar’s James Peckham says that the Galaxy Watch 4 is “a great choice for anyone who owns a Galaxy smartphone.” He adds that it’s still worth getting if you don’t have a Samsung phone, but you will miss out on features like blood pressure and ECG measurements. Peckham also says battery life wasn’t a huge concern and that the watch has “good fitness features, strong battery life, and a comfortable design.” However, the compatibility issues may be disappointing for potential buyers.
- Tom’s Guide’s Kate Kozuch calls the Galaxy Watch 4 “the first Wear OS smartwatch worth your money.” She adds that it’s an excellent upgrade with design updates, refreshed software, and a breakout BIA (bio-impedance analysis) system. And the fact that the series is cheaper than its predecessors is surprising but welcome. She would have preferred better and more consistent battery life and finds that the new Wear OS is missing some key features. That said, she concludes that “the Samsung Galaxy Watch 4’s success comes down to integrating as obnoxiously well with Galaxy devices as the Apple Watch does with the greater Apple ecosystem.”
- SamMobile’s Danny D. says the hardware upgrades make the Galaxy Watch 4 series noticeably fast and that “the hardware improvements alone justify the upgrade” if you have any older smartwatch. The even more exciting update is on the software side, saying, “the work that Samsung has done with Google on Wear OS will benefit the entire Android smartwatch ecosystem.” He adds that Samsung seems to have priced the new watches to be more attainable and that they offer “incredible value for money with great new features, a completely new chipset and access to Android’s vast library of apps.”
What people like you think of the Galaxy Watch 4 and Watch 4 Classic
There was a lot of hype surrounding the Galaxy Watch 4 and Watch 4 Classic, especially after Google mentioned details about the new collaboration with Samsung and Wear OS 3.0. To find out how excited (or not) you were about the new smartwatches and software, we issued a few polls before and after the launch of the watches.
After a leaked marketing video showed off the UI in action about a month before the Galaxy Watch 4 series was officially announced, we asked you whether you liked the new UI. An overwhelming majority was in favor of the new user interface. Out of the 1,560 votes in total, 93% of AA readers liked what they saw.
Before the launch: Do you like the new UI of the Samsung Galaxy Watch 4 series?
After Samsung announced the Galaxy Watch 4 series, we put a simple question to our readers. Is the Galaxy Watch 4 hot or not? Once again, most of you think that Samsung has a winner on its hands, with more than 80% positive votes out of the 1,422 total.
Samsung Galaxy Watch 4 hardware and design
The Galaxy Watch 4 and Classic models offer different designs and are made for different users. Both Galaxy Watch 4 models offer thinner cases than their respective predecessors — good news if you weren’t a fan of the Galaxy Watch 3’s bulkier design.
The Galaxy Watch 4 is made of aluminum, and the Watch 4 Classic has a stainless steel case. You’ll also notice the bigger overall footprint of the Classic model due to the rotating bezel for navigating around the interface. You can navigate around the regular Galaxy Watch 4 by swiping along the side of the watch case, but most users will likely just use traditional swipes and taps on the touchscreen.
The Galaxy Watch 4 and Watch 4 Classic are for different users, but you'll get a great-looking device whichever model you choose.
The Watch 4 and Watch 4 Classic both come in two sizes. The standard model can be configured with a 44mm case and a 1.36-inch display or a 40mm model with a 1.19-inch display. The Watch 4 Classic comes in 46mm or 42mm case sizes, with the same display sizes as the standard Watch 4. All displays in question are AMOLED panels, and they all offer higher pixel densities than their predecessors.
The Galaxy Watch 4 and Watch 4 Classic can use the same 20mm watch straps despite the different sizes. The silicone straps you get with the watch aren’t the best, but there are plenty of excellent third-party options to choose from.
Both of the bigger-sized watches come with 361mAh batteries, while the smaller models have 247mAh batteries. Samsung says all Galaxy Watch 4 devices should last around 40 hours. It depends on your usage, though. In his testing, Jimmy managed to push it to that mark. But with more than average usage, he needed to charge the watch every day. When you’re low on battery, leaving the watch on the charger for 30 minutes will supposedly earn you 10 hours of usage. Charging from 0-100% will take about two hours, however, which is quite slow.
Samsung has finally upgraded the SoC, RAM, and storage with the Galaxy Watch 4. All models come with Samsung’s new 5nm Exynos W920 chipset, 1.5GB of RAM (up from 1GB), and 16GB of onboard storage (up from 8GB). The chipset is a big deal, though. Not only is this the first 5nm chipset in a Galaxy watch, but the company also says it’ll offer a 20% increase in CPU performance. The chip is made with two Cortex-A55 cores and a Mali-G68 GPU. Coupled with 50% more RAM, the Galaxy Watch 4 should have no problem moving through the new Wear OS software.
Good news for always-on display (AOD) users: the new smartwatch chip boasts a dedicated low-power display processor (the Cortex-M55), allowing the main CPU to stay off when in situations that require a small amount of power.
Samsung Galaxy Watch 4: Fitness and health features
Samsung always tries its best to incorporate all the fitness and health features you could want, but it can fall short at times. This year, Samsung hopes the new BioActive sensor on the Galaxy Watch 4 line will provide more accuracy than previous watches. The BioActive sensor comprises three hardware sensors: an optical heart rate sensor (PPG), electrocardiogram (ECG), and a bioelectrical impedance (BIA) sensor.
To be clear, the heart rate sensor and ECG hardware are the same sensors that appeared on the Galaxy Watch 3 and Active 2. But the Galaxy Watch 4 series has new algorithms to make up for those issues. In his review, Jimmy was actually impressed with the Galaxy Watch 4’s accuracy.
Samsung's improved algorithms help garner more accurate heart rate data — one of the Galaxy Watch 3's main pitfalls.
The new BIA sensor is worth talking about, as well. After 15 seconds of recording, your Galaxy Watch 4 will attempt to determine certain body composition metrics, including your skeletal muscle, basal metabolic rate (BMR), water retention, and body fat percentage. To get proper readings, you’ll need to provide some manual data like your height and weight. This was fairly accurate compared to Jimmy’s smart scale, but we couldn’t compare it to the accurate information you’d get with a professional body composition analysis machine.
Sleep tracking is important for many users, and now that the Galaxy Watch 4 can last over a day on a single charge, it’s likely many owners will wear their watches to bed. The Galaxy Watch 4 series tracks sleep stages overnight and provide you with a sleep score in the morning.
Now, though, the watch works in tandem with your Galaxy smartphone to provide snoring detection in conjunction with blood oxygen readings. Your smartphone can detect your snoring throughout the night and provide that data for you in Samsung Health. You’ll also get blood oxygen data each morning, which records every minute instead of every 30 minutes as we usually see on fitness watches.
Not much is new on the fitness-tracking front. The Samsung Galaxy Watch 4 series offers carryover features like a digital running coach (which we loved on the Galaxy Watch 3) and VO2 max data. Samsung says automatic workout detection will lock on much faster in this year’s devices.
Samsung Galaxy Watch 4 vs Galaxy Watch 3: What’s new?
The Galaxy Watch 3 launched in 2020 as Samsung’s standalone flagship smartwatch. The Galaxy Watch 4 Classic is the more direct Galaxy Watch 3 predecessor, while the regular Galaxy Watch 4 is the spiritual successor of 2019’s Galaxy Watch Active 2.
The Watch 4 series comes with two screen sizes, measuring 1.2-inches and 1.4-inches across. The physical rotating button gives the Classic model a larger watch face, with 46mm and 42mm options. The standard model features 44mm and 40mm faces. The Classic is also thinner and lighter than the Galaxy Watch 3. For the most comfortable feel, the standard Watch 4 is the thinnest and lightest of the lot.
Apart from the design differences, the Watch 4 and Watch 4 Classic are identical. So, we’ll pit the Watch 3 against the Watch 4 Classic for the rest of this comparison. The rotating bezel returns, and the only notable aesthetic difference is with the buttons. They remain on the right edge of the watch but are flatter and more elongated this time around.
There are plenty of internal upgrades, though. The Galaxy Watch 4 series come with 1.5GB of RAM and 16GB of storage, compared to the 1GB of RAM and half the storage with the Watch 3. If you’re looking to store a lot of music on the watch, which you can do with both YouTube Music and Spotify, the Watch 4 series is the way to go.
A new chip brings noticeable performance improvements as well. The Galaxy Watch 4 series comes with Samsung’s 5nm Exynos W920 SoC, which reportedly brings a 20% faster CPU and 10x GPU performance over the Galaxy Watch 3’s Exynos 9110. The larger models of the Galaxy Watch 4 and Watch 4 Classic when the battery capacity battle. They come with 361mAh batteries, compared to the 341mAh unit of the larger Watch 3. However, the smaller Watch 4’s and the Watch 3 keep the same 247mAh battery.
Of course, the biggest change here is the new software experience with the Galaxy Watch 4. It’s not as different at first glance as you might think. Samsung’s One UI Watch bears a striking resemblance to the Tizen OS running on the Galaxy Watch 3 — except that it is far more capable. We’ll talk more about the new Wear OS below, but it’s worth noting that the Galaxy Watch 3 will not get the new software.
Dive deeper: What are the differences between the Samsung Galaxy Watch 4 and Galaxy Watch 3?
As good as the Galaxy Watch 3 was, its health-tracking abilities weren’t the best. Heart-rate tracking and sleep tracking were unreliable, and some fitness tracking features were hit and miss. The Galaxy Watch 4 not only improves health tracking across the board but adds new sensors to the mix. You get body composition analysis with the BIA sensor, blood pressure monitoring, and ECG measurements. There’s a pretty significant catch, though. You’ll need a Samsung phone to see this data, and blood pressure monitoring is only available in Australia for now.
The Galaxy Watch 4 Classic is priced cheaper than the Galaxy Watch 3’s launch price as well. The latter launched at $399 and is currently available for around $340. Instead, you can get the base model of the Classic for $349. If you’re looking to save more, the $249 starting price of the standard Watch 4 is quite compelling.

What does the new Wear OS bring to the table?
There are many new things to talk about in design, health and fitness, and software, but we all know why you’re here — to see the new Wear OS. You’ll find a detailed breakdown in our Galaxy Watch 4 review, but here are some highlights.
The Galaxy Watch 4 series now runs on Google’s new Wear OS platform with Samsung’s One UI Watch overlay. This is the first time Google is allowing OEMs to customize the look and feel of the smartwatch platform. This means the software on Samsung’s new watches will look much more like the version of One UI that appears on its smartphones. That could be a good or a bad thing, depending on how you feel about Samsung’s design language. Still, it allows for more customization options throughout the entire OS, including a way to theme your watch to match your Samsung phone.
Don’t miss: Everything you need to know about Wear OS
Thanks to the Wear OS software, the new Galaxy Watches also syncs important settings from your paired smartphone and auto-install compatible smartphone apps on your watch.
Speaking of apps, the addition of Wear OS means more Google apps are now available on Samsung’s smartwatches. There’s YouTube Music with offline listening support, Google Maps for turn-by-turn directions, as well as other popular Wear OS staples like Strava, Adidas Running, and more. Samsung Pay is also available on both Galaxy Watch 4 models, and users can download Google Pay if they’d rather use Google’s payment service. Unfortunately, there’s no MST support, so you’re working with NFC payments only.
Wear OS also has a much larger app library than the Tizen platform. If you couldn’t find the right app on your older Samsung smartwatch, there’s now a good chance it’ll be available on the Galaxy Watch 4.
For those hoping for quick access to Google Assistant on the Galaxy Watch 4, keep hoping… Samsung says Google Assistant will be available on the Galaxy Watch 4 series at a later date. For now, you’ll need to use Bixby.

Its redesigned on-screen gesture controls make it much easier to answer and dismiss calls and alerts. It also implemented a new quick-access widget — accessible from the watch face — that lets you check your connected earbuds‘ battery, manage touch controls, and change noise cancellation options straight from your watch. Also, the Galaxy Watch 4’s hardware buttons let you toggle between recent apps, just like on your phone.
Android Authority asked Samsung about its update commitment with the new Wear OS software, specifically how often it’ll release major OS or security updates to the watches. The company said it could not commit to a schedule but will fix bugs as they pop up. Software support will make or break the new Wear OS experience, so we’re hopeful that it’ll be better than it ever was with older versions of Google’s watch OS.
What are some good Samsung Galaxy Watch 4 and Watch 4 Classic alternatives?
If you’re hoping to get a smartwatch running the new Wear OS, you might have to wait a while. That said, while the Samsung Galaxy Watch 4 and Watch 4 Classic seem pretty great, they will not be the watch for everyone. Here are a few of our recommended alternatives:
- Apple Watch Series 6: This one’s a no-brainer if you have an iPhone. For iOS users, the Apple Watch is hard to beat. It rivals the Galaxy Watch 4 in terms of fitness and smart features. It’s a seriously great wearable. If you’re on Android, though, the Galaxy Watch is your best bet.
- Fossil Gen 6: The recently announced Fossil Gen 6 is the first to come with Qualcomm’s Snapdragon 4100 Plus and tacks on a new heart rate sensor, SpO2 tracking, and faster charging batteries. Unfortunately, you’ll have to wait till 2022 to get the update to Wear OS 3.
- Garmin Venu 2: If you want a smartwatch that prioritizes accurate fitness and health stats, the Garmin Venu 2 is a good option. It’s one of our favorite fitness watches of all time, thanks to its long feature set and relatively affordable price. It’s not as “smart” as the Galaxy Watch, but it’s likely the better fitness wearable.
- Fitbit Sense / Versa 3: Fitbit’s Sense and Versa 3 smartwatches should not be overlooked. They don’t run Wear OS, but they have many smartwatch features (including Google Assistant support) and stellar health tracking.
