“a very cool smart watch with infinite battery life”
“don't expect to have the watch without charging for more than 10 days. The good thing is that, in contrast to instinct 2x, this one can indeed charge quite rapidly with the sun”
“Design was awesome, too bad software and battery is complete crap.”
“For Garmin to launch a $500 outdoors-focused hiking watch without offline maps in 2025 is pretty hard to swallow.”
“Getting 40 days of battery and potentially even more with sun is insane.”
“honestly I think it was an expensive mistake.”
“It's very strange for me, because if we add sleep time to this (I mean where the display is off during the night) it will be 2 month of screen work to reach this point.”
“it's just leagues better than the Fitbit. You won't be disappointed. More accurate data, comfy fit, long battery life. Recommend.”
“Lacks maps - perhaps unforgivable in a mid-tier navigational watch.”
“I see high drain of about 10% a day with any custom watchface from Garmin watchface builder (3rd party) even basic ones.”
“Surprisingly not on instinct3 but it has a much more vented band.”
“After installing CIQ and any applications (for example battery monitor), the watch starts to discharge 1-2% per hour.”
“The Garmin Instinct 3’s MIP screen is pretty damn good.”
“The blue pixels in AMOLED burn out quickly. But 4 months is too fast.”
“Big pluses for me are the low-key display that also helps the battery last week's/months, the shortcut to custom timers such as 4 mins for epi on arrests, and the built in flashlight”
“I hiked for about an hour, and my Instinct3 lost 7–8% of battery.”
“Garmin Instinct 3 is good. Basic display with no touchscreen, which I find much easier to view and control when kiting. Also gets much better battery life than my Fenix did.”
“I ended up with the Garmin Instinct 3 Solar. I was looking at the Forerunner’s but went with this one because it’s a little heavier duty, I’m rough on tech, and the battery life is incredible.”
“switched a month ago to a Garmin Instinct 3 and not looking back. Battery life + workout are a whole different game on the Garmin”
“after 9 days of heavy use 20-25hours gps tracking and constant bt conection with the phone the watch its still on 40% battery”
“Watch face displays I have 36 days remaining right now, and it will charge simply by being in ample ambient light or outside”
“Garmin instinct3 is rugged price of work if you’re okay with the basic looks. Lasts almost 3 weeks on a single charge”
“Garmin Instinct 3 Solar. 36 days battery baby! Had several Garmins over the years, never been disappointed.”
“contrast is substantially better on the Garmin Instinct 3... best of any watch screen I have ever seen.”
