Apple Watch Shuts Down While Exercising
Several users have reported that the Apple Watch shuts down without warning while exercising. Your Apple Watch lets you track your exercise with the Workout app.
There are several types of workouts you may do, such as walking, running, swimming, or hiking. If your watch shuts down itself in the middle of your exercise session, you may lose all of your workout data meaning you won’t know how much you exercised.
This article explains how you can troubleshoot if your watch unexpectedly shuts off while you are working out. A lot of factors can create this problem: low battery, outdated software, or problematic third-party apps. This guide will help you find out what the issue is, and ways to fix it. Please, after each step, try checking your watch to see if you have fixed the problem.

Such a bummer. Apple Series 3 with these symptoms.
Always shuts off during light-medium activity. I coach/ref youth sports and specifically bought it for the timing features.
Updated multiple times, un&re- paired, restarted, etc etc.
Was going to buy I new one, probably just kick the down to someone and buy a Garmin that actually works.
Everytime I commit my digital life to the Apple ecosystem, I get bitten. Time Machine that fried all my data, bunk MacBook laptop that they didn’t have parts for, now this. I guess it has been 25 years of using their products, but still.
I have been experiencing this same issue intermittently for a few months. I hit an exercise, looks good, but the watch shuts off about a minute into exercise. Watch will not restart unless placed on charger. Restarts and shows full charge.
Hey this is exactly what happens to me and seems to happen when I’m outside so I can’t put back on charger till I get back home. What did you end up doin
Same issue. AW 6, 3 months old running 7.3.3. + iPhone 11 pro running 14.4.2. I skate ski all winter / roller ski all summer. Got it for heart rate, distance and time. I use the Apple Watch app on the ‘Cross-Country Ski,’ setting because it’s the closest to skate skiing (though actually different from CC skiing). At least half of the time it turns itself off mid-workout. It’s even alerted me with haptics in the middle of a hill climb asking if I’m done with my workout. Heart rate is spiking and what? It thinks I’m napping in my car? The app sucks. I wonder if sweat is the issue? Or the sleeve of my glove or jacket rubbing across the watch face? We just need a simple ‘Lock On,’ setting on it so it keeps recording until users tell it to stop. Love to have one of their designers come out on trail to see if they can keep up. Too much coding in high design infinity loop chairs. Not enough field trials. To date : fail.
Same issues as you all , very frustrating , phone shuts down when cycling , can’t restart until on charge 2 secs later it all working with full battery
After months of my watch shutting down in the middle of my runs (not only am I trying to keep track of pace/distance, it’s also my music source) I almost took off my watch to throw it in the road! Sooo very frustrating, and I have tried multiple fixes…going to try again tonight when I get home from work!!!
My watch shuts off just after I begin a swim work out. It won’t turn back on unless I put it on the charger. Once it’s been on the charger for a few seconds, it turns back on (Apple logo appears). If I immediately take it off the charger, it continues to reboot, and when it’s done, I have 80% charge left on the battery.
My Apple I watch stops onThe middle of an app called Workout. I agree with the many people who have experienced same issue. Please fix this bug with updates to software.
I charge and watch continuously blacks out and says low battery. My iPhone Does same thing. I have wasted two days resolving and do not wish to correct my typos. Please update software.
This is exactly what I’ve been experiencing for the last few months with my Apple Watch 4 cellular.
Battery full, go for run, watch turns off mid run. When I turn it back on, the battery is at 10%. I was using the Nike Run Club app. Sometimes, it wouldn’t turn off mid run but still the battery would go down from the run from 95% to 10-15%—ridiculous.
After I updated the Watch OS, things improved and 1) it didn’t turn off and 2) the battery only went down to 60-70%.
Then today…same story, but now using Strava. Watch turns off mid run. When I press the button only the time shows with the lightning bolt meaning battery is very low. So I put it on the charger, and right away it goes to 70% battery.
This is terrible!
I am having the same problem.
Happens to me even using the apple-installed workout app! I almost threw my watch into an on-coming car this morning I was sooooo mad!!!
This happens to me all the time lately when I am working out. Today during my Spin class it shut off in the middle. When it finally came back on, half my workout was over and my battery said it was at 85%. I did not mistakenly turn it off with my wrist. I’ve unpaired/re-paired it. Software is updated. I’ve done all the things that have been suggested and this is still an issue. Why is Apple denying they have an issue? They are making it sound like the consumer is doing something wrong! I’m about ready to just go get a FitBit.
I’m having the same problem again now, seemed to be better after a couple of the updates over recent months, but has returned on every run I’ve tried since the most recent update.
My Apple Watch is turning off in the middle of my run! I see the red lighting bolt indicating my battery is low and my watch turns off, but when I get home and connect to my charger I had 65% battery. The frustrating part is I lost my run data 😞. I expected better from Apple! Please find a fix for this issue.
My AW4 does the same thing. Any one know if the AW6 has been crashing as well?
Yes I have this problem with AW5 9 months old, battery condition showing as 94%. During workout the watch will randomly shut down, often at about 50% charge. It won’t restart at all or shows it’s on reserve, but when put on charge it shows as around 50%. I’ve spent about 8 hours talking to apple service and it’s been back twice. First time they just said the battery’s fine. Second time they said they won’t repair it because it has a scratch. But I’ve seen a number of reports of exactly the same issue.
I’ve started to experience the exact same thing with my AW 4 cellular. I’ve used it for about two years without any problems, but now I can’t use it for my workouts anymore.
It’s really frustrating.
Hi Terry, literally what you have described is word for word the same as my aw5. Did you find a solution in the end? I went into Apple today and they just unpaired and repaired which I have already done, they said there was no issues with my battery. Iv noticed this only seems to happen on outdoor run and not ever on walking workouts.
I have had exact problem. Does Apple want people to purchase a new I watch?
I am having this same issue. I have tried all of the above on several occasions. Since there was just a new update, I will try the factory reset and unpairing one more time. This is soooo frustrating. I just deleted the Nike App thinking that was the problem and moved to Strava… same thing happened this morning.
My Apple Watch 5 has started turning off while I am running. My earbuds say, “Apple Watch lost,” and I look at my watch—it is completely turned off. All three times I have come back home, put it on the charger and it turns back on, it is nearly completely charged. I have tried all the above suggestions.
I’ve been having this issue for since I purchased the apple watch series 5 back in December/January. It seems to have gotten worse as well. I’ve been talking to apple support about the issue for a while and we’ve tried sending in the watch for repair. However, the watch was returned without being repaired because the issue could not be reproduced. Since then I’ve learned from support that this is a known issue for some users. They say that an update is in the works with a fix. After 6-7 calls and chats with Apple Support I have to say, this is the worst Apple experience I’ve had yet. Thank you for writing about the issue.
