Garmin created the best alternative to the Apple Watch when it came out with the Vivoactive 3 Music. For 2019, Garmin has updated that device with the Vivoactive 4 series, which includes the 45mm Vivoactive 4 and the 40mm Vivoactive 4s. Minor hardware changes accompany equally minor smartwatch software changes in this device, but that's because new fitness features steal the show.
This is the 3rd generation Vivoactive fitness tracker I’ve owned. The 4S is much improved over the Vivoactive 3. Longer battery life, more functions/measurements and it recognizes activities once programmed for the individual. Readability is good even with the slightly smaller face. The lower profile and smaller band make it attractive. Select an option to add your device to your Garmin Connect account:.

If you have already paired another device with the Garmin Connect app, from the or menu, select Garmin Devices Add Device, and follow the on-screen instructions.
Garmin added a ton of fitness improvements to this watch, including optional all-day pulse ox measurements, hydration tracking, new breathing exercises (that don't suck), new custom workouts, on-screen animations, and more. Unsurprisingly, all those improvements add up to the Vivoactive 4's $349 starting price, which is at least $100 more than what the Vivoactive 3 Music goes for nowadays.
Those features add a lot of value and push the Vivoactive 4 ahead of even the Apple Watch in terms of fitness, but I still have a soft spot for the Vivoactive 3 series—and plenty of happy users may skip this upgrade.
New hardware
I tested the 40mm Vivoactive 4s and immediately noticed the newly added sleek-and-shiny touches on the watch's case. The circumference now has a thin casing of metal, and the two side buttons are metal as well. The Vivoactive 4s includes an additional side button for lap, back, and menu access. While it took a few tries to get used to the new input method, I was able to navigate the watch using that side button, the other side button, and the color touchscreen fairly easily.
The display itself is a backlit, transflective memory-in-pixel panel, which, in comparison to LCD panels, uses technology that allows it to consume less power. That's one of the hardware factors that lets the Vivoactive 4s get up to seven days of battery life (by Garmin's estimation). It has essentially the same quality as previous Vivoactive displays, so the watch face is always visible, and you won't have trouble reading it while running outside in the sun.
While familiar, this display is in stark contrast to the AMOLED panel on the new Garmin Venu smartwatch, which was announced at the same time as the Vivoactive 4 series. That device, however, starts at $399 due not only to its AMOLED panel, but also for some additional features that aren't present on Vivoactive 4 devices (keep an eye out for Ars' review of the Venu in the coming weeks). Thanks to that big hardware difference, the Venu will more closely compare to the Apple Watch Series 5.

The Vivoactive 4s is packed full of fitness-tracking sensors: accelerometer, gyroscope, altimeter, optical heart rate monitor, onboard GPS/Galileo/GLONASS, pulse ox, compass, and a thermometer. Both the heart rate monitor and the GPS have been updated with new sensors, so they should be even more accurate and more efficient than those in previous Garmin wearables. There's also storage space on the Vivoactive 4s for music, and all Vivoactive 4 smartwatches have onboard music storage as a standard feature. That means you won't pay extra for it like you had to when Garmin first introduced the Vivoactive 3 Music after the Vivoactive 3 had been available for a little while.
Garmin has improved its devices significantly over the past year or two when it comes to music storage. I had a 'better late than never' attitude when Garmin finally added music storage to some of its wearables, and I was pleasantly surprised to see that the desktop interface for transferring tracks wasn't as horrid as those of other smartwatch makers. Since then, Garmin has added support for downloading tracks and playlists from Deezer, iHeartRadio, Spotify, and Amazon Prime Music, so paying subscribers can download music to listen to while running (and using a pair of connected Bluetooth headphones) without their smartphones present.
Overall, I'd argue Garmin has a better system for downloading and playing music from a smartwatch than Apple has and, therefore, the rest of the competition as well. While Apple makes it incredibly easy to pick tracks to sync and play music on its watches, you're limited to the music and other audio you have in your iTunes account and Apple Music (if you subscribe to the latter). LTE-equipped Apple Watches also make it easy to stream Apple Music playlists while working out. But users aren't locked into one ecosystem with Garmin, and I'll always prefer that flexibility over the alternative. Unfortunately, though, that means we will likely wait a long time for Apple Music integration to arrive on Garmin smartwatches—if it ever happens at all.
New software
All-day pulse ox
There are a lot of new fitness features on the Vivoactive 4s, but let's start by talking about one that directly affects battery life: optional all-day pulse ox. The pulse ox sensor inside the Vivoactive 4s allows it to measure the level of oxygen in your blood based off of the heart rate and breathing data it collects. Most healthy people will see a pulse ox percentage close to 100 in the Garmin Connect app after the pulse ox sensors gather enough data, but percentages dramatically lower than that could signal health problems. Like most consumer wearables on the market today, the Vivoactive 4s isn't a medical device, but it can capture useful information that users can share with their doctors who can then decide if there's a problem that needs to be addressed.
AdvertisementPrevious versions of Garmin devices like the Vivosmart 4 could measure pulse ox on the fly or during sleep to capture more data over the course of the night. Now, if you enable continued, all-day pulse ox measurements, the Vivoactive 4 will periodically take readings throughout the day.
But this constant monitoring will dramatically reduce battery life, and unless you have a known problem with your blood oxygen levels that you want to monitor in a new way, I wouldn't recommend it. For the first few days of testing the Vivoactive 4s, I enabled pulse ox during sleep, and I got roughly four days and four nights of battery life out of the smartwatch. That's a little more than half of Garmin's estimated battery life for the device in smartwatch mode (up to seven days). It's still a good battery life for a wearable by normal standards, but you will have to charge the Vivoactive 4s about twice a week if you choose to enable pulse ox while sleeping.
I still believe pulse ox information isn't necessary for most users, but it's encouraging to see Garmin include a pulse ox sensor in nearly all of its new wearables and actually use it. Fitbit has been touting the pulse ox sensor found in almost all of its wearables introduced since the Ionic, but the sensor isn't active in any Fitbit devices—and there's no telling when Fitbit will put it to use.
If you’re shopping for a fitness tracker, you might be wondering about the differences with the Garmin Vivoactive 4 vs 4s.
Garmin offers several lines in their smartwatch collection, and the Vivoactive line is designed for general fitness tracking. The Garmin Vivoactive 4 and the Garmin Vivoactive 4s are the latest models in this line, released in late 2019.
To help you make a choice, you should first think about what you need from your fitness tracker.
What Are You Looking For in a Fitness Tracker?
There are a couple of categories of things that might help you choose the right fitness tracker.
The first, and most obvious, is its fitness tracking capabilities. Does it track steps, measure heart rate, and map your GPS location?
Another feature that you’ll be looking for is different kinds of activity tracking. Can it differentiate between walking, running, and hiking? What about other activities, like yoga or weight lifting?
For the data nerds out there (like me), you might be looking for advanced analytics. Some smartwatches will track your sleep, measure your pulse ox, and estimate your recovery time. You might find these things useful, or you might never look at them.
The cost is of course something to consider. Garmins run the gamut from $100 to almost $1,000. So you should consider your budget and let that inform your choice.
Finally, does fashion matter to you? Some Garmin watches are designed with form and elegance in mind. Others are designed purely for functionality.
So What’s the Difference Between the Vivoactive 4 and 4s?
Here’s the good news. The Garmin Vivoactive 4 and the Garmin Vivoactive 4s are the same in most of those categories.
They have the same functionality in terms of fitness tracking and analytics. Each will track your runs, measure your heartbeat, and give you access to the Body Battery feature.
They’re also the same price – $350 MSRP. You can find them on Amazon for about $250.
The only real difference between the two watches is their form. The Vivoactive 4 is slightly larger and the Vivoactive 4s is slightly smaller.
Comparing the watch faces, the Vivoactive 4 is 45mm in diameter, and the 4s is 40mm in diameter. The Vivoactive 4 sports a slightly larger watch face (1.3″ to 1.1″) and display resolution (260x260px to 218x218px).
The watchbands are also slightly different sizes. On the Vivoactive 4s, the watch bands are 18mm wide and they fit a wist that is 110-175mm in circumference. Compare that to the 22mm wide watchband and the 135-200mm circumference on the Vivoactive 4.
Vivoactive Hr Watch Faces
The color options are different on the two watches, as well. The smaller Vivoactive 4s comes in rose gold, silver, and slate, while the larger 4 only comes in slate and silver.
The size also causes one functional difference in the two watches – battery life. There’s a slightly smaller battery in the Vivoactive 4s. It’s rated for 7 days of general use, compared to 8 days for the Vivoactive 4.
Garmin Vivoactive 4 vs 4s: Making the Choice
The only significant functional difference between the two watches is the battery life, and that difference is marginal at best. Unless you’re using it in GPS and music mode on a long hike, you’ll probably never notice.
That essentially leaves fashion and form as the deciding factor. Do you want a larger watch with a larger wristband? Get the Garmin Vivoactive 4.
Do you want a smaller watch with a smaller wristband? Or do you like the rose gold? Go with the Garmin Vivoactive 4s.

If you’re looking for something similar, but slightly cheaper, you may want to consider the Garmin Vivoactive 3. It’s very similar to the 4/4s, except without the ability to store and play music.
And if you’re looking for something that’s made just for runners – as opposed to general fitness – check out the Garmin Forerunner series.
