This watch is a step up over the Garmin Vivoactive 4. I own both the Vivoactive 4 and the Vivoactive 5. The Vivoactive 5 has a clearer display and the battery stays charged much longer than my vivoactive 4. I only get about two days of charge with the vivoactive 4. The Vivoactive 5 gives me eight days before I need to charge again. I like the Vivoactive 5 very much.

# Garmin vívoactive 5: Great Fitness Watch, Terrible Sleep Tracker ## Rating: 2/5 for Sleep Tracking I've been using the Garmin vívoactive 5 for sleep tracking over several weeks, and while it's a solid fitness watch, the sleep tracking is fundamentally unreliable. If accurate sleep data matters to you, look elsewhere. ## Major Sleep Tracking Failures ### 1. **Completely Misses Sleep Periods When You Change Locations** The watch frequently fails to track entire sleep sessions if you move to a different bed or room mid-night. Multiple times, I woke up in the middle of the night, moved to a different bedroom, went back to sleep for 2-3 hours, and the Garmin simply stopped tracking—pretending I was awake the entire time. This isn't a minor glitch; it's a fundamental flaw that makes the data useless for anyone dealing with fragmented sleep. ### 2. **Cannot Distinguish Between Sleep and Watching TV** The watch regularly mistakes lying still on the couch watching TV for sleep. On multiple occasions, it logged 1-2 hours of “sleep” that was actually me lying down watching Stranger Things or other shows. If the device can't tell the difference between unconscious sleep and conscious TV watching, what's the point? ### 3. **Fails When You Remove the Watch** If you take the watch off during the night (for a shower, for example), it ends the sleep session entirely. No recovery, no second tracking period—just missing data. This happened multiple times and makes the watch unusable for anyone who might need to remove it briefly during the night. ### 4. **Co-Sleeping Interference** When my toddler slept in bed with me, the watch's tracking became even less reliable. Movement from another person seems to confuse it, leading to either missed sleep periods or wildly inaccurate wake time calculations. ### 5. **Inconsistent Data Accuracy** Comparing the Garmin's data to my actual sleep experience revealed huge discrepancies: - **Dec 14**: Watch showed 3h 45m of sleep ending at 3:26 AM. Reality: I was awake 2:30-6:00 AM (3.5 hours), then slept until 8:30 AM. The watch missed an entire sleep period. - **Dec 15**: Watch claimed I went to bed at 10:51 PM. Reality: I was watching TV until midnight. - **Dec 17**: Watch showed no data at all despite wearing it all night. When your sleep tracker can't even get the basic start/end times right, the detailed sleep stage data (deep/light/REM) is meaningless. ## What Actually Works To be fair, the watch does work reasonably well when: - You sleep in the same bed all night - You don't remove the watch at any point of the night and reapply it - You're sleeping alone - You go straight from awake to bed (no TV time) In these ideal conditions, the sleep stage breakdown seems plausible, and the efficiency calculations are probably in the ballpark. But who has perfect sleep conditions every single night? ## The Bigger Problem The fundamental issue is that the Garmin treats sleep tracking as a simple motion + heart rate algorithm. It has no way to verify whether you're actually asleep or just lying still. It can't handle anything outside its narrow assumptions about how sleep “should” look. For someone trying to address chronic sleep issues—the exact use case where accurate tracking matters most—these failures make the watch actively unhelpful. You can't identify patterns or measure progress when the data itself is fiction. ## Bottom Line **Buy this watch if:** You want a fitness tracker with decent battery life and you only care about general sleep trends (e.g., “I usually sleep 7 hours”). **Don't buy this watch if:** You need accurate sleep data for medical reasons, sleep therapy, or tracking actual sleep patterns. The tracking is too unreliable to be useful for serious sleep ----- **Tested with:** Garmin vívoactive 5 **Testing period:** December 2024 (2+ weeks of nightly use and external journaling) **Use case:** Sleep restriction therapy for chronic middle-of-night insomnia​​​​​​​​​​​​​​​​

Does exactly what I was hoping for without overwhelming me. I was looking for something to help me understand my fitness and track my exercise as well as sleep. I still wanted it to have smart watch features as well, though. It does all of this well. How I have it set up, the battery lasts me 7-10 days. Battery life was another important feature to me.

My third iteration of this product line. Purchased to replace aging Vivoactive 3. Significant upgrade with much more health data and improved accuracy, particularly in sleep measurements. Much better in my lap swimming. Hats off to Garmin for making it affordable and significantly improving its usefulness and performance.

The watch is intuitive, easy to customize and simple to integrate into daily life and planning. Great fit for walking, running, lifting and cycling. I refer to it often and it's helped a great deal in working towards my health goals. It's easy enough for a beginner to use, but has enough info that a seasoned athlete would benefit from it. Battery life is great, especially if you aren't using the gps feature.

Mine works great, for the most part. It does have a habit of coming out of sync with Gamin Connect though. This last time it took forever to get it back in sync. Now, every time I happen to walk about 25 feet from my phone it vibrates and sends a message, "Phone Disconnected." And when I walk back within that range, it sends another message, "Phone reconnected." This has become rather annoying.

This item is very thorough at collecting overall statistics about a persons health. It is a hreat little tracker if you dont need all the bells and whistles. If you are apprehensive about having all your health stats in the hands of Google like the fitbit and Google tracker, this is the one for you.

I've owned a few Garmin watches and this one has been the worst. With only 2 lasers on the back it often times won't track, well anything. It's pretty and smaller, which is great, but definitely needs to have the 4 lasers like all of my other watches.

I used a vivoactive 4 for quite a few years and I was overall happy with it. I have been looking at the 5 for months and my wife bought one for me for Christmas. There is a bit of a learning curve, perhaps slightly frustrating at times but now that I've worked through that, actually prefer the interface. I still occasionally forget how to do things like advance set in a work workout. I did just notice a couple scratches on edge of the bezel and crystal. I don't think I am particularly hard on it wearing it exclusively on the back of my wrist, where I often (especially in the beginning) work the 4 on the inside of my wrist, where I believe it was more at risk of being knocked around. I think the crystal was better protected by the bezel, so I may need to be more aware of what I may be doing to cause the scratches. My wife has frequent problems with shut downs on here Watch from a competitor, when we take a boxing class which I never experienced with the 4 or 5 Garmin. I have suggested she talk to others in the class about her experience. Overall, I would purchase again.

My old Vivoactive HR broke down and it was time to upgrade. I bought the Vivoactive 5 even though there is a newer version since it was less expensive. The Vivoactive 5 connects to my phone immediately where the HR model took a while to connect after a run or workout. The display is bright and colorful and there are many options for the watch face. The only change I would like to make it to have the time of day on the workout option. Maybe there is a way to add this but I haven't figured it out yet. This model does so much that I can't imagine the Vivoactive 6 having even more features. I'm sure it does but the 5 has plenty of features for me.
