Our Vivoactive 4 review was first published as a "first look" on 5 September 2019. It's now been updated after full testing of heart rate, health, sports and other features.
The Garmin Vivoactive 4 is a sports watch that does a damned good job at playing smartwatch.
Like the Vivo series watches that came before it, this is Garminās riposte to the Apple Watch, Samsung Galaxy Watch and the rest of the full-fat smartwatch clan. Itās all about offering something thatās equally adept at tracking your runs as it is letting you know what the weather's going to be tomorrow.
Successor to the Vivoactive 3 Music, which launched last year, the Vivoactive 4 shifts the emphasis back on health and fitness adding features like respiration tracking, support for Garminās Coach run training platform and the ability to follow workouts for the likes of yoga and pilates from the watch screen.
On the smartwatch front, itāll still dish out your notifications, offer contactless payments and let you take your music out on your run sans smartphone including support for offline Spotify playlists.
The Vivoactive 4 comes in two sizes with the smaller 40mm model priced at Ā£259.99 in the UK and the 45mm coming in at Ā£279.99. In the US, both sizes come in at $349.99.
That makes it cheaper than the Venu, Garminās first watch with an AMOLED display, which offers the same features plus a full color touchscreen display. That also puts it in the same pricing realms as the Samsung Galaxy Watch Active 2, though it is still cheaper to own than an Apple Watch Series 5.
On paper, itās another well-priced watch that offers a whole lot. But with the Venu now on the scene, should this be the Garmin smartwatch you should go for? Weāve been putting the larger Garmin Vivoactive 4 through its paces to find out. Hereās our full verdict.
Garmin Vivoactive 4: Design and interface
After ditching that blocky, rectangular form of the first Vivoactive, Garmin thankfully decided to move to a circular watch design with the Vivoactive 3. Then when the Vivoactive 3 Music arrived on the scene, it took that very same design and gave things a bit of a spit and polish, specifically in the watch face department.

Itās retained that same glossy finish up front, which does a pretty impressive job of making that transflective display a bit more lively. It helps to create the illusion that thereās actually a more vibrant screen in place here.
Itās also kept that attractive black bezel and thankfully thereās been no signs of scuffs or scratches in our time with it. You still get one of Garminās 18mm quick release bands keeping it in place, which does mean you have the option to swap in another strap and thereās a decent bunch to choose from though a little on the pricey side.
It also gets the pretty customary 5ATM waterproof rating that means you can go swimming with it up to 50 metres depth.
As mentioned, the Vivoactive now comes in two different sizes. We spent our testing time with the 45mm version, which offers a slightly larger frame than the Vivoactive 3 Music (43mm). Does that jump up in size dramatically change the experience of wearing it day-to-day? Weād say no. It takes up roughly around the same space on your wrist. Itās been comfortable to wear all day and at night to track sleep for us too.
Itās about as attractive an undeniably sporty smartwatch you can find right now. Itās not too thick and that band is clearly up to the task to withstand the sweatiest of workouts.
In terms of other redeeming physical features, Garminās Elevate heart rate monitor tech lies around the back, while thereās two physical buttons on the side of the watch flanking the touchscreen display. Itās a responsive touchscreen display too, showing no signs of lag when youāre swiping up and down to view your data screens.
Speaking of those data screens, Garmin hasnāt introduced the same dramatic UI changes itās made more recently on some of its Forerunner and Fenix watches. That means you donāt get the benefit of larger font displaying your data or increased data fields. Though itās still a version of its UI thatās easy to get to grips with.
Pretty much everything you need is accessible from the main watch face screen letting you swipe up and down to see an overview of your day, resting heart rate data, calendar appointments and more. If you press and hold the lower physical button, that will push you into additional settings that will let you access and downloaded apps, add additional widgets and change up the watch face.
You do have Connect IQ support here, giving you access to more watch faces, apps, widgets and data fields if youāre not already satisfied with the abundance of features that are already on board.
Garmin Vivoactive 4: Fitness and health tracking
Outside of Fitbit, Garmin has always impressed us with what it offers on the fitness tracking front and thatās no different on the Vivoactive 4.
Itās got the best that Garmin has to offer here. Itāll do the basics like count steps and automatically monitor sleep. But thereās also Garminās other staple features like the Move Bar that springs into action when youāve been inactive for a period of time. It will adjust daily step goals based on your step counts previously logged too.

Thereās also all-day stress tracking and Garminās new Body Battery feature to give you a better insight into your energy reserves for the day. Bottom line, if you want motivational fitness tracking features, youāre well covered here.
It also joins a growing list of Garmin watches that includes a Pulse Ox sensor. This is most relevant for offering richer sleep metrics, though switching on this sensor will impact on battery life. So thatās something to be aware of.
On the watch, that data is represented at a glance on the My Day widget. If you want to dig deeper, then you have the option to do that by tapping on the individual fields of data. Though generally it was enough for us to see the snapshot data.
From an accuracy point of view, we pitted its step tracking against the Google Fit app on Android and the Withings Sleep bed monitor to test its reliability for sleep monitoring.

Above and below are snapshots of a typical day and a night putting these features to use.
What we found is that step tracking tended to generally be within 500 or so steps of Google Fit. But the gap could be wider on occasions too. From a sleep tracking point of view, things were a little more erratic. Sometimes the Vivoactive 4 matched the Withings Sleep, and other nights it recorded one or two more hours of sleep data. It's really tough to accurately assess sleep outside of a lab.
Granted you do now get a breakdown of sleep along with pulse oximeter and respiration-based data too, but itās hard to trust when it can at times be wildly out from a sleep monitor weāve come to rely on.

Your health stats are also presented in a similar fashion to your fitness tracking on the watch itself. These comprise of heart rate, stress level, Body Battery score and respiration rate data. The data can be a little overwhelming in Garmin Connect and it's poorly labelled in our opinion.
The latter is a new addition for Garmin and goes beyond the guided breathing features that Apple, Samsung, Fitbit and Google Wear OS watches offer. Itās a feature powered by heart rate analytics firm Firstbeat and measures each breath you take in through heart rate variability measurements.
These respiration rate readings can be taken during some exercises, like yoga as well as during the day and sleep. Weāve seen this kind of respiration tracking promised by first generation smart garments that places sensors close to your chest to measure breathing rate during exercise.
The data offers another insight into your current state of fitness. Firstbeat says typical resting breathing rates should between 12-20 times per minute during rest and around 40-50 times per minute during intense physical activity.
The reliability of this data though is heavily reliant on the accuracy of the heart rate monitor where those measurements are being taken from. While Garminās sensor seem generally pretty reliable for all-day heart rate readings, Firstbeat does suggests pairing up a chest strap monitor for exercise, which casts some doubt over its reliability as a metric for exercise sans a chest strap monitor.
Garmin Vivoactive 4: Sports tracking
In typical Garmin fashion, youāre well catered for in the sports tracking department. All the key sensors are present. That includes GPS, an altimeter to measure elevation and an accelerometer to track indoor activities like treadmill running.

Core sports profiles are covered letting you track running, cycling and swimming (still pool only).
Thereās support for tracking a round of golf and a host of other activities. These all seem to be in normal working order. We ran, swam and recorded a bunch of indoor workouts and the Vivoactive 4 is clearly a very dependable sports watch.
Though as the screenshots below illustrate, the Vivoactive did have a tendency to report significantly larger calorie burned numbers.

The big changes here though lie in improving how well the Vivoactive behaves as a workout partner. We had rep counting introduced in Garminās previous generation watches, though it wasnāt the most reliable or most intuitive of features.
With increased support for cardio, strength, yoga and pilates workouts, you can now go beyond tracking basics like heart rate and workout duration. You can select to follow preinstalled workouts with animations to follow on the watch or even make your own. It's important to mention here that in workout mode, it won't track your movement. It's just instructing you on how to perform the different exercises.
Take yoga for instance, which you can select from the workout tracking menu on the watch. From there you swipe up to pick from three different preloaded workouts. You can view the workout in full before you decide to take it on and then the watch will display a very simple animation along with a countdown around the edge of the screen for each exercise. Itās simple, works well and is easy to follow.
The nice thing is that you can also create custom workouts from the Garmin Connect app and then sync them to the watch. Itās thankfully very easy to do and thereās a good range of individual exercises to pick from to build a wide range of workouts. Hopefully the feature will evolve to Garmin building more of those prebuilt workouts for you to move onto the watch.
Garmin Vivoactive 4: Heart rate accuracy
Garmin includes a heart rate monitor on pretty much every one of its watches and that also includes the Vivoactive 4. Its inclusion unlocks a host of exercise-based and fitness based features, some of which weāve touched on already.
Our testing in this section is very much focused on its ability to offer a reliable measurement of effort levels during a workout. During workouts you have the ability to view heart rate zones, receive heart rate alerts and thereās also support to broadcast heart rate data over paired ANT+ devices.

We ran through it our usual tests taking it for runs, working out in the gym and putting it to the high intensity test all against a Polar H10 heart rate monitor chest strap. What we found was pretty much what we've found with Garmin watches that house its latest generation heart rate sensor tech.
Itās reliable for most workouts, but you should grab a chest strap if you yearn for reliable data for high intensity workouts.
The screenshot above is from a 40 minute high intensity indoor bike ride and average HR readings, maximum HR readings and the graphs produced by the Vivoactive 4 were well in line with the chest strap. Though a closer inspection of the graphs show that at one point the Vivoactive 4 is a little slower to react to the jump in effort level.
When we turned our testing attention to a running intervals session, itās a very similar story to what weāve found with other Garmin watches packing that latest sensor tech. It can be a little slow reacting to the drops and spikes in heart rate.
Garmin Vivoactive 4: Smartwatch features
Until Garmin Venu, the Vivoactive range was Garmin's only true smartwatch. It was one of the first to get payment support, proper music features and felt the closest in terms of what Apple, Samsung and others offer around this price point.
Essential reading: Best Garmin watch faces to download
Garmin ticks off most of the key smartwatch features here. You have notifications which you can respond to if you are paired to an Android phone (sorry iPhone people). You can play and control music on your smartphone and thereās music storage to pile on your own tunes or store offline playlists from supported music streaming services.
Thereās Garmin Pay to unlock payments and you do have that Connect IQ support. Thereās actually not a whole lot that we haven't already seen.
As a smartwatch, it goes about its business in a very competent way. Notifications pop up just as they do on your paired phone, thereās a nice dedicated widget for your calendar, though it wonāt nudge you when a big appointment is coming up. Music features are better implemented than other smartwatches that offer that functionality too.
Thereās a dedicated store to add additional watch faces, widgets, data fields and apps and things are improving on that front as Garmin has spent more time finessing this aspect of its ecosystem. Though when it comes to syncing and installing new things to your watch, it can be at times painfully slow and some times cause the app to crash.
Garmin doesnāt do anything groundbreaking on the smartwatch front. It covers the bases and features work without any major issues. Itās clear though that its storefront and syncing could be better.
Garmin Vivoactive 4: Battery life
Garmin claims that you should get up to eight days in smartwatch mode, which means not putting sports tracking or sensors like GPS to regular use.
With GPS and music streaming, itāll get you six hours. GPS battery life is up to eighteen hours. Those are all improvements on what the Vivoactive 3 Music, most impressively in the GPS only battery performance, which is up by five hours.
You donāt get the same battery saving modes that you get on pricier Garmin watches like the Fenix 6 series, though it doesnāt seem as essential a feature for the Vivoactive 4.
Youāll get a weekās worth of use with a mix of sports tracking, smartwatch features and fitness tracking in play. There are features that can have a significant impact on battery life performance. Music streaming for instance and particularly using the pulse oximeter all day or even just during sleep.
For hardcore users dabbling in marathons, ultras or full weekends of walking this is clearly not going to be enough. But if you want a sport-focused smartwatch that will get you through a whole week, the Vivoactive 4 will certainly do the job.
- Great screen
- Animated workouts are a nice addition
- Crammed with features
- Connect IQ Store still a bit flaky
- Pulse Ox sensor will drain battery
- Heart rate accuracy iffy at high intensity
