No hill score after 42,000’ of elevation gain in 3 weeks

5922749 — Thu, 16 Apr 2026 02:27:38 GMT

I’m using my Enduro 3 daily to track my Appalachian Trail hike and still don’t have a hill score. Any advice? I have GPS and heart rate on.

Battery 100%

With software 21.39 after a recent charge, the battery has been stuck at 100% for 3 days.

21.39 Morning report still causes reboot

Cuba1hr — Sun, 12 Apr 2026 06:31:07 GMT

Hi guys. Does anyone still gets crash and reboot while scrolling through Morning report? It happened to me 3-4 times now on 21.39. Not every morning. It was solved in previous firmwares, but now it happens again.

Usually I have to go to widgets - Sleep score to end "sleep" after the restart, but today it already remembered today's sleep score and it stayed in sleep focus on main screen.

It happens after Today's suggestion (I think), just before the advice for today.

Also the 21.39 firmware (or the one before) messed up the order of my widgets.

Update in version 21.39

7964763 — Fri, 10 Apr 2026 09:56:07 GMT

Enduro 3 FW 21.39, beta versions disabled
A notification appeared that an update is available
Has anyone installed it? Are there any new bugs?

After the latest patch 21.39, there are still plenty of bugs, especially when the game freezes or reboots.

Is there any word on a smaller form factor (42-45 mm)?

user624 — Wed, 08 Apr 2026 21:23:18 GMT

Is there any word on a smaller form factor of the Enduro 3 series? With the Fenix series moving to AMOLED, the Enduro seems to be the MIPS solar sapphire series now. I have a smaller wrist so I need something in the 42-45mm range. I could maybe get away with 47mm, like the Fenix, but 51mm is definitely way too large.

Solar power capped 250%

PeterFdeVries — Wed, 08 Apr 2026 11:06:08 GMT

Hi fellow Garmin users,

I am on the latest stable version (21.39) and I saw that charging it in full sunlight now gives a 250% solar charging.

Wasn't that more in earlier versions? Is the solar charging capped to 250% now or was it always like this?

I am curious about your thoughts!

Notification center doesn’t work with since FW 21.39

2844325 — Mon, 06 Apr 2026 18:56:33 GMT

since latest FW enduro 3 doesn’t show notification from apps. (iPhone) and on Notification Center it says waiting for data with a red ! I tried to fix this on my own and it worked normal for a day or two. Have no idea what I did though. But now it doesn’t work.
also since latest FW. I get storm alert reports a couple every day. Sometimes after an activity is started.
please fix this bugs

Bug Report: No turn by turn alerts on reverse course

Marc Krawitz — Sat, 04 Apr 2026 18:14:17 GMT

I did a 15K point to point race today. Rather than taking the bus I ran from the finish to the starting line following the provided route but using the reverse function. I failed to receive any turn by turn alerts on the reversed course.

However when running the official race in the forward direction, the turn by turn alerts worked quite well.

My altimeter is crazy inaccurate

jtshaw — Fri, 03 Apr 2026 22:26:56 GMT

I've noticed in the last 2-3 months the altimeter is way off on my Enduro 3. Routes I run frequently are showing 50+% more vertical gain than they used to with the same watch (the old results were correct). I ran a 100k two weeks ago that had just under ~12k feet of vert and my watch recorded 16.5k. It used to be REALLY accurate when comparing routes to CalTopo and compared to officially measured course and now I can't trust it anymore. The watch appears clean and when I calibrate it outside it calibrates correctly, but often drifts to crazy off numbers.

Attached as a screenshot that shows how variable and weird it is. My house is ~240 feet above sea level which is pretty much exactly what it says when I calibrate it with GPS. I walked up a hill that is ~200 feet higher and back to my house in the time on this graph and now it's saying is 474 feet at the house... rebooting, etc. doesn't appear to help.

Daily Suggested Workout 173bpm for 15 minutes?

ajwms2222 — Wed, 01 Apr 2026 01:38:00 GMT

I'm 45 and my watch keeps adjusting my max hr to like 203bpm and then gives me suggested runs that would make my heart explode. Why

Issues with heart rate measurement when using HRM pro+

2times4 — Mon, 30 Mar 2026 13:07:01 GMT

Hi all,

With the latest update on the watch i noticed issues when using the HRM pro+ belt. It seems that there are issues with the connection. The display on the watch shows a black heart and instead of the value just ---

This happens while running (road and trails) and biking. Garmin Conect shows a graph like these below.

Anyone with similar issues out there?

Low Power Analog Clock/Watchface

Sepulchre — Sun, 29 Mar 2026 17:54:52 GMT

Maybe I'm missing something, but I could not find a low power analog clock/watchface when the battery saver is activated - just an hour hand and a minute hand, as the second hand will draw too much battery power to redraw the screen each second.

As someone who prefers analog vs. digital, I would much prefer the analog over the digital when I turn on battery saver to squeeze 90+ days. Just a simple hour/minute hand with battery level and date like the digital version.

If I'm missing a step in settings, please let me know. I found the other analog face, but like the Enduro face, it went from 90 days to 60 days. I'm looking for a low power analog face that will still give me 90 days like the default digital face. And I think if it is not an option, it should be in a future update.

Enduro 3 screen freezes (21.39)

9293580 — Fri, 27 Mar 2026 13:35:01 GMT

After nine months of using the watch, I started experiencing problems with the screen. I will try to explain it in more detail and provide a video. The problem can be seen in the video and can be summarized as follows. When I swipe the screen, it sometimes (not always, but often) leaves a "fingerprint" of the previous screen, with residual information from the last widget or app. I have reset the watch to its factory settings twice, but it has not resolved the issue.

Backlight Keeps Turning On After Flashlight Activated

Sepulchre — Thu, 26 Mar 2026 00:38:36 GMT

I have tried every setting that I can think of to remedy this. But my backlight keeps turning on when I turn the flashlight on. It's rather annoying and distracting at night or in the dark especially because you can still control the intensity via the side buttons.

Is this a bug? If this is hard baked into the ROM, will you please address this in a future update? I don't need two lights on.

Enduro 3 (21.39) Strength Training can't do tow training plans in one activity

BitByter — Wed, 25 Mar 2026 10:54:28 GMT

I have different training plans depending on what I want to do in the gym. (Some for worm up and different strength training plans)

If I start my session and select a training plan I can't change that during, or after I finished it to do another one.
Please change that so I can do one activity for my workout. At the moment I have to do separate strength activities for one work out. Which becomes a mess because I also run to the gym and back and do rowing in the gym, so I have at least 5 activities or more depending on how many training plans of mine I am doing.
And I can't use the group activity to record multiple activities in a row beaus training plans re not working there. (Activity to record multiple sports in a row no training plan working

)

Crashing while starting navigation to point of map

9e910c9073ce4fefb3a4080ddeb4fe3d — Mon, 23 Mar 2026 09:33:12 GMT

After starting a bike activity, I accessed the map navigation feature.
While attempting to scroll to my desired destination, the watch unexpectedly restarted.

is it possible to use two different GPX files (courses) within 1 continuous activity?

AmazingBikeToursThailand — Sun, 22 Mar 2026 11:48:59 GMT

Will be hiking from Chamonix, France to Zermat, Switzerland later this year.
I have the entire route saved as GPX files.
Is it possible to press start on an activity, in this case HIKING, select the required GPX file / course, reach the end of that course, then without pressing stop to end the activity, select the next GPX file / Course?
There will be times when I reach the end of a route / course and wish to continue hiking some more that day and I would prefer to record each days hike as 1 activity.
I have tried doing this as a test and I don't think it is possible.
However, like to know if this can be achieved.

Enduro 3 (21.39) still rebooting in Notification

parkdigital — Fri, 20 Mar 2026 15:05:33 GMT

Firmware 21.39 still reboots in Notifications. The interface seems really laggy when scrolling through notifications. When I try to open a notification, sometimes it reboots the watch.

21.39 Bluetooth song skipping still causes reboot

8455664 — Fri, 20 Mar 2026 01:21:40 GMT

Hi all,

Just ran and the watch still reboots when skipping songs via Bluetooth headset. I’m wondering if anyone else is seeing the same problem ? It happens when running with Stryd pod and core body temp. I’ve had the enduro 3 for nearly a year without any problems skipping songs and I’ve not received any update from Stryd or core body temp for a few months so it’s not a new app. I’m aware this has been reported by myself and others but the latest firmware was suppose to resolve the problem. I’m creating this ticket to keep visibility on the problem and allow others to report on problems

Enduro 3 (21.39) Climbing screen looks when screen look is deactivated

BitByter — Wed, 18 Mar 2026 09:23:10 GMT

I really enjoy using the climbing activity, but for some time now the screen has been locking automatically as soon as I select the difficulty of a route. I've disabled the screen lock in the activity settings, and the screen lock is generally disabled for all activities. Despite this, my screen and all buttons are still locked.
