My COROS PACE 3 is having multiple issues, and I’m losing confidence in COROS
I’ve had my COROS PACE 3 for less than two years, and I use it for running and swimming. I genuinely loved the watch and its user experience, but over the past week, I’ve started experiencing several frustrating issues.
Severe battery drain: The battery is draining much faster than usual, even when I’m not recording any activities. As you can see in the screenshot, I charged it to 100% and went to sleep, but the battery usage was unusually high.
Touchscreen issues: The touchscreen started freezing and sometimes stops responding completely.
Heart rate sensor problems: The heart rate sensor only seems to work when I’m recording an activity.
Random restarts: Sometimes the watch restarts by itself.
Strange noise: I occasionally hear a strange electronic sound coming from the charging contact area while I’m wearing the watch, even when it’s not connected to a charger.
All these problems have started recently, and honestly, I’m getting tired of dealing with them.
I really liked COROS and was happy with the overall experience, but having so many issues with a watch that’s not even two years old has made me question its reliability.
I’m now seriously considering switching to Garmin, even though I used to really enjoy using COROS.
Has anyone experienced similar issues with the PACE 3? Could this be a software problem, or does it sound more like a hardware failure? I’d appreciate any advice before deciding whether to switch to Garmin.

I have been in contact with coros for my watch problems. And they sent me the Coros pace 4 since they finished the Coros Pace 3. (Mine was the pace 3).

So I feel very happy and satisfied with how Coros handled this problem. Thanks for everything I have made this update for the people that want to know what happened

I have had my Coros watch for about 2 years and absolutely love it. No complaints at all—until recently. I got into a cycling accident which shattered my watch (as well as a couple bones...). I reached out to Coros about getting a repair. For ~$80 USD, you can trade in your broken but functional watch for a refurbished one. Sounds great. Except the process takes forever, and I've now been sans watch for 3 weeks...

First, it took several days for the "repair team" to even approve the repair, despite the support team always getting back to my emails immediately, asking for patience. Then, I dropped the package off at the post office with the label they provided, and again wait several days for it to be delivered to their warehouse. Now, it was delivered 5 days ago, but as far as I can tell, the replacement has not been shipped—again waiting for the repair team to review and approve.

All the while, I can't train as effectively as the Coros app does not automatically import with my Strava-tracked activities, which also (obviously) lack heart rate data, making Coros unable to estimate effort/training loads. Gah!! I love love love this brand, but this repair process is really a headache.

3% per day power consumption with smartwatch use only.

I have an original Pace Pro and I use the main running features primarily. I owned Garmins and they typically have a booklet or an online guide with hundreds of pages to show you how to use the watch.

Is there something equivalent to that from Coros? Something like a guidebook or complete guides that I can start to customise my watch further to my own likings or learn new hidden features that my watch can do.

Coros is testing my patience. I have a Pace 3. I try to charge it with the charger it comes with and it doesn’t work consistently. I try to charge it with the flat charger they sell and it doesn’t work consistently. So tired of waking up for my morning run and finding out my watch didn’t charge overnight. Anyone have any charging hacks to get these things to work consistently?

can I set up lap pace alerts when running a runna training plan through my coros pace 4? I know you can set up a pace alert by distance or position through the auto lap feature. but in any given run I can have multiple different lap lengths split up by rest periods and the pace alerts become irrelevant. i’d love a feature where you can automatically set pace alerts at the end of any lap, no matter what variables have changed.

how do lap pace alerts work when running one of coros’s built in plans? my current runna plan is about to end and considering my options as i’ve found porting over runna training plans to be clunky.

Is there any way to get rid of the option to just start this instead of picking the body part? I always end up forgetting to select one. Plus I manually add the sets afterwards it takes too much time durring the session

New to Coros. New to this watch. I've had it for a month. Always the same GPS settings.

The watch began the month by ticking down from a full charge at 1-3% per day, depending on if or how long I ran. It has never ticked down more than 3% in a day, even with 8-10 mile runs. I watched it religiously because it's new to me and I wanted to make note of the battery life as it was a selling point... I don't do much with it beyond a check of the temp, a glance at the time, and a run generally every other day.

Last night I charged it to 100% and it's already down to 90% today. I just looked at my watch face and was shocked to see that it had already dropped by that much. No runs, just sitting on my wrist.

My app had a hard time syncing with the watch this morning. The app sync just kept spinning. I ultimately disabled and restarted the bluetooth on my iPhone - and even then it took another 30 more seconds for the app to connect. I'm not saying that had anything to do with it, just a small point on the curve.

I'm seeing a million posts of varying degrees about possible resets and charging for an add'l time after 100%, etc.

But I'm wondering if anyone has had any similar experience with this particular Apex 4, or with a Coros in general. Nothing in my use would have kicked the battery drain 3-10x what it's been. And I can't imagine it's already lost that much of it's efficacy?

Thanks for any insight - - -

Después de actualizar el pace 3 empezo el drenarse la batería de manera exagerada, en menos de 2 horas pasa de 100% al 0%.

El reloj tiene poco uso (marzo 2026) me lo enviaron de reemplazo del anterior reloj que sufrió el mismo problema después de actualizar...

Hi everyone,

Does anyone know if COROS has released a new Halloween-themed watch face this year?

I’ve been checking the watch face options but haven’t seen anything new yet. Just wondering if there’s a new Halloween watch face coming soon, or if I somehow missed it.

Thanks!

May you help me with guidelines of how made the follow up?

Thank you 谢谢, 

Has anyone ordered a pace 4 pro recently? How long did it take to get shipped out? I am assuming next week being I just ordered last night.

I’m considering purchasing the APEX 4, but there’s one ridiculously simple feature that has me second-guessing COROS entirely.

Being able to see the actual time of day down to the SECOND at any given moment I want. If I’m spending $500 on a watch I should have the luxury of looking down to see the exact second of the time of day. Like, 3:00:33, not just 3:00.

From what I understand, certain COROS watch faces display seconds temporarily when you activate the screen, but they disappear after a few seconds. There just is not enough info on this.

I’m open to Coros and seconds don’t have to be on display 24/7. I just want the ability to check the exact time, down to the second, whenever I want.
For a company producing premium GPS watches with advanced training metrics, navigation, and incredible battery life, this seems like such a basic feature to overlook.
I’m coming close to pulling the trigger on a Garmin Enduro 2 instead, partly because of this.

Am I missing something, or does anyone else find this frustrating?
