How Long Does a Garmin Watch Battery Really Last? Every Model Compared (2025)
Answer: Many days – much longer than Apple Watch. Let’s dive in
97% of Apple Watch owners are happy with their watches. That means they’re happy with charging their watch every one or two days. You’re not one of those people! You want Uber multi-day battery life, and Garmin gives you that, but the situation varies significantly between its watch models.
This article tells you how long the battery will last for every Garmin smartwatch when used as a basic watch. Recording sports uses considerably more battery, so I’ll include more information to indicate how long a recording time you get for sports. Even Apple’s $800 Watch Ultra 3 only gives you 14 hours of proper accuracy GPS recording. Hardly “Ultra”. Most Garmins are two, three or four times better than those for sports.
Battery Longevity
The more often you charge a battery, the sooner it will eventually wear out and need replacing. For Apple, that’s typically 2-3 years. With Garmin, it’s longer, usually 5 years or so. It depends.
Solar Charging
Garmin also offers a limited number of model options with solar charging. Its Instinct model effectively gets ‘forever’ battery life because of solar.

Why are you providing battery life with screen off? Is this year 2017 or what?
on or off, apple Watch owners perhaps don’t all appreciate the magnitude of diffrence to what they experience.
Haha fenix 8 pro 51mm, 27 days ! Mine won’t get past 2 weeks in smartwatch mode !
The asterisk on the official specs will have a crack at explaining the difference. Perhaps you’re not meant to move to get the 27 days?
Fenix 8 pro 51 mm charging every 5-6 days. 27 days xD tell me which one. Using LTE always on, not standby mode, charging every 2 days. 15k run, which last about 1h20min, took on LTE (which is not working at all) and music, about 15% of battery, so same like AW ultra 3. Fenix 8 pro is a nighmare, the worst garmin i have ever had, since more than 10 years.
5-6 days with trainings about 6 times per week. But even in smartwatch mode, there is no change to have 27 days. Maybe with everything off.
I am very happy with my Enduro 3 (and new eTrex Touch now too). I usually charge it from 20-30% to 80-ish, so I’m using like half of its capacity. With all that I charge it once a week (on Fridays, when I do my backups). It involves 10-14 hours of GPS related activities (running/walking/cycling) and some 2 hours of non GPS activities (strength, yoga). I use smart notifications, so Bluetooth is always on. I don’t measure SpO₂, only HR is on. I suspect, that using OH1 for running/cycling reduces battery usage somewhat, but no idea if really (I turned off the “backup” wrist HR, which is on by default on Enduro 3 and, probably Fenix 8 series).
Long distance hiking with constant map on with navigation and wrist HR reduces battery by ~1.5 %/hour for me. So all in all I’m very happy with its “longevity”, as I already performed long three full day hikes with one half-charge and still had plenty of it left.
I don’t track how much solar is involved here, but my outdoors activities happen usually during early morning, so half of the year in total darkness.
Just wondering: the Enduro3 has much better battery performance in smartwatch mode than the Fenix/Tactix solar but lacks in the GPS recording time deüratment…
Not that this really matters but looks doesn’t seem right.
