Features of the Galaxy Watch 4 The standard Galaxy Watch 4 sports a contemporary design and features brushed aluminium lugs. These aluminium lugs were used to enclose the black-polished metal body of the watch. Concerning the Galaxy Watch 4 classic, it made use of a style similar to the Galaxy Watch 3. A conventional style is evident with the use of stainless steel for the body and a physical rotating bezel for interaction. The display quality on both Galaxy 4 models is the same. The display has a pixel density of 330ppi and is equipped with a 1.19in or 1.36in circular AMOLED. Compared to previous versions, the physical buttons on the watch's right side now work with the Bio-Active Sensor branding concerning the overarching fitness hardware inside the watch. The top button now functions as the home key, while the bottom key, when tapped, brings up an interface that sources information regarding the body's water retention, bone density, and BMI. Essentially, the watch has been equipped with a new Body Composition app. According to Samsung, the Watch 4 can take blood oxygen readings and track your sleep. Just like the Galaxy Watch 2, it has something like the ECG, which has now been approved for usage in over 40 regions of the world, especially those that already feature the previous editions of Samsung products. Furthermore, Google has teamed up with Samsung to fuse Wear OS and Tizen OS into a single entity. As confirmed by Samsung, it is set to power the next generation of Samsung watches coupled with features like wellness and fitness apps (supplied by Fitbit, which Google owns).Following Galaxy Watch 4's announcement, Samsung quickly clarified that Samsung powers Wear OS on the Watch 4 Series to stand out from the crowd as other manufacturers will adopt the OS platform in the foreseeable future. Tizen, called One UI Watch, was prominent in previous Galaxy watches, and the Korean company is making the most of the incredible platform. In the Galaxy 4 classic, it made use of a physical bezel. This makes it easier to access Google Maps, use the Google Play store, and use Google Pay, which improves the user experience. As regards hardware, the Watch 4 Series debuts new components. They include Samsung's latest wearable-centric chip, the 5nm Exynos W920, which promises to be better than the best Qualcomm currently offers, the 12nm process Snapdragon Wear 4100+, and the Galaxy Watch 3's 10nm chip. Also, Samsung promised that this latest silicon would be 1.25x faster in processing information than the Exynos 9110 and "8.8x smoother in graphics performance." It has 1.5GB of RAM and doubles the storage of the Galaxy Watch 3-from 8GB to 16GB, and the battery experience has also been improved. Samsung noted that the Galaxy Watch 4 series could last up to 40 hours per charge; that's the next level. The full specifications
The Samsung Galaxy Watch 4 (stylized as Samsung Galaxy Watch4) is a smartwatch developed by Samsung Electronics. It is the first Samsung watch to run Google's Wear OS since the Samsung Gear Live, and the first watch to run Wear OS 3, co-developed by Samsung and Google. The device largely followed the design language of the preceding Samsung Galaxy Watch Active and Galaxy Watch 3, but including all new software. The watch also included EKG, body compositional analysis, and blood pressure monitoring via the new Samsung BioActive sensor.It was announced on August 11, 2021, at Samsung's Unpacked Event alongside the Samsung Galaxy Z Flip 3, Samsung Galaxy Z Fold 3 and Galaxy Buds 2.

Design and comfort

Regardless of what color you choose for the aluminum frame, the Galaxy Watch4 series has a safe, generic round design that lets your watch face make the statement rather than the aesthetics of the overall watch. There are tons of options for watch faces and different watch hands, but one thing that bothers me is the limited color options for the faces and hands. I would have loved a green color option for the watch face below, for example, but it's not available for some reason.
The Galaxy Watch 4 has standard and classic versions that vary in thickness and strap design.
Antonio Villas-Boas/Insider
The Galaxy Watch4 is the thinnest and lightest smartwatch of Samsung's recent smartwatches, and it's a comfortable watch for it. The Galaxy Watch4 Classic is a little thicker, thanks to its rotating bezel. The included silicone straps are also comfortable, but they're pretty stiff — the strap sticks out quite a bit where they connect to the watch itself. Specifically for the Galaxy Watch4 Classic's included strap, the loops that keep the excess strap from flailing around are ineffective. That's a shame, and I'd feel the need to buy another strap had I bought the Galaxy Watch4 Classic.

General usage


Telling the time with the Galaxy Watch4 is best with the always-on display

The Galaxy Watch4 doesn't reliably show you the time when you do the "raise-your-wrist-to-tell-the-time" gesture, unless you cartoonishly exaggerate the gesture, tap the screen, press a button, or rotate the bezel on the Classic version. The easy solution is using the always-on display mode, which reduces battery life, but the watch still lasts a full day with ease.

Notifications are helpful on the Galaxy Watch4

Smartwatches are great for checking notifications without having to look at your phone, as well as receiving messages and making calls from the watch. When the Galaxy Watch4 is connected to your phone via Bluetooth, all this works just fine. When you're beyond your phone's Bluetooth connection, however, the Galaxy Watch connects to your WiFi network (or LTE if you opt for that option. Almost everything still works fine when the watch is connected to a WiFi network, except for phone calls, which is a shame to find. In fact, I wouldn't even get a notification for a phone call when I was outside of Bluetooth range from my phone, but text and messaging notifications came through. There's also the occasional time when the Galaxy Watch4 struggles to find my WiFi network or stay connected to WiFi when I move around different parts of the house with a mesh WiFi system.

Google's Wear OS operating system, brought to you by Samsung

One of the biggest upgrades to come to the Galaxy Watch4 series is the adoption of Google's Wear OS smartwatch operating system instead of Samsung's Tizen smartwatch (OS). That may cause concern for anyone familiar with Google's neglected and poor Wear OS, but with Samsung's help, it's actually pretty great on the Galaxy Watch4 series. It looks and feels like Samsung's excellent Tizen OS, but Google's Wear OS means the Galaxy Watch4 is compatible with significantly more apps from Google's Play Store.

Health and fitness


General fitness tracking with the Galaxy Watch4 works well

The Galaxy Watch4 has an array of health and fitness tracking features you'd expect from a premium smartwatch, including workout tracking, heart rate monitoring, blood pressure measuring, an ECG feature, sleep tracking, blood oxygen measuring, and stress tracking.
The Galaxy Watch 4 is always ready to record a workout session, which can cause some issues.
Antonio Villas-Boas/Insider
The basic workout and fitness tracking stuff work great, but it can be a little over-eager to automatically record a workout. For example, the Galaxy Watch4 thinks I'm working out while I'm taking a shower. Perhaps I shower more aggressively than the average person? Either way, it's annoying to delete my erroneous shower workout day after day to avoid messing with my actual workout tracking.

Sleep tracking with the Galaxy Watch4

For sleep tracking, it's impossible to tell if the Galaxy Watch4 is properly measuring my REM, light, deep sleep, and wakefulness without comparing its readings to a medical sleep test. Still, I can tell when I've been awake, as I'm waking up a couple of times a night to feed my baby, and the Galaxy Watch4 sometimes doesn't register those waking moments well at all. It makes me doubt that the Galaxy Watch4 is properly tracking the other sleep metrics.

Sleep tracking on the Galaxy Watch 4 doesn't seem to be very precise, though it does provide a decent summary.
Antonio Villas-Boas/Insider
Still, I guess I get an overall sense of my sleep quality — my sleep score in Samsung Health is consistently a poor 40 out of 100, which isn't surprising on account of my baby. But I don't need a smartwatch or health app to tell me I'm getting lousy sleep these days.

ECG on the Galaxy Watch4 can be hit or miss

The ECG works well, but it's extremely dependent on having the Galaxy Watch4 properly positioned on your wrist, and there seems to be a very narrow margin for that proper position. I'd easily get inconclusive readings when the watch wasn't well positioned, and I even got a reading saying that I was experiencing atrial fibrillation.
Heart rate monitoring on the Galaxy Watch 4, like most smartwatches, is often inaccurate.
Antonio Villas-Boas/Insider
Thankfully, cardiologist and Director of Cardiology for Dallas-based State of the Heart Cardiology, Dr. John Osborne, debunked the reading and said I wasn't experiencing atrial fibrillation. Dr. Osborne attributed the erroneous reading to a confused algorithm caused by external feedback like motion, talking, or even simply breathing. It's not uncommon for smartwatches with ECG features to be "fooled," he elaborated. Here's what a normal ECG reading should look like:
The sensors require precise positioning, which isn't ideal for daily activity or excessive movement.
Antonio Villas-Boas/Insider

Measuring your body with the Galaxy Watch4 is an awkward experience

The big new piece of health-tracking tech in the Galaxy Watch4 is the Bioelectrical Impedance Analysis (BIA) feature that measures body composition, like skeletal muscle, basal metabolic rate, body water, and body fat percentage. The fancy new body measurement feature with the BIA sensors seems fairly accurate. Every reading I took showed slightly different numbers, but they were largely pretty consistent, and that's fine to give you a general idea of your body metrics. With that said, taking a measurement was often a frustrating experience. Like the ECG feature, the BIA seems incredibly sensitive to where the watch is on your wrist to take a reading. Also, placing your middle and ring fingers on the two buttons on the side of the watch to take a body measurement is incredibly awkward.
The device's metrics, though no replacement for a doctor, can give you a sense of your body composition.
Antonio Villas-Boas/Insider
The overall takeaway here is that sleep tracking, the ECG, and BIA features are just meant to give you a general idea, and they don't replace a doctor or real medical measuring devices.

Battery life

The Galaxy Watch4 has a solid day-and-a-half-long battery life with the always-on display mode enabled and with general use (without workout tracking). Enabling bedtime mode when I went to sleep, which turns off the display and puts the watch into "do not disturb" mode, helped with getting that extra few hours into the next day. Even with a good workout, the Galaxy Watch4 will comfortably last a day until you lay it down to charge overnight. Longer workouts, especially those that use GPS like a marathon or a 100-mile bike ride, will likely considerably run down the battery. The Galaxy Watch4's battery life shouldn't be rated with the always-on display mode disabled, as it's such an important feature to keep on for the basic function of telling the time. You can help extend battery life into the second day by enabling bedtime mode when you go to sleep, which turns off the screen and notifications.
Overall, the watch is a solid choice for Android users.
Antonio Villas-Boas/Insider

Should you buy it?

The Samsung Galaxy Watch4 is the closest option Android users have to the premium Apple Watch experience and is the obvious choice for those looking for a comprehensive and quality smartwatch. Although Samsung now has the Galaxy Watch5 Pro (our pick as the best Android smartwatch), the Watch4 remains a quality budget smartwatch for Android users. However, it's a shame the ECG feature is limited to Samsung phone owners. If you do want a smartwatch or fitness tracker that works with most phones, you may want to consider a Garmin instead. The Galaxy Watch4, starting at $220, is also very well priced, especially for such a premium and feature-packed watch.
