My Apple Watch sensor burns

I’ve had my watch for over 2 years and have only recently started getting burn marks on my arm from wearing it. I wear my watch every day and use it for tracking exercise and movement. I’m so disappointed I can’t wear it

If you are feeling the watch is hot on your wrist (or generally hot to touch) a genuine heat burn is possible, but relatively unlikely because the watch battery is only small and does not really have enough power to make the watch hot for long enough to cause burning. You would certainly notice if this was happening, because making the watch hot would discharge the battery fairly quickly and you would be complaining about battery life.


It is more likely you have become sensitive to something in the watch or watch band, or possibly some kind if irritant like a soap or detergent trapped under the watch and not easily rinsed away. Take a look at this support document, and if you are unsure then consult your doctors who can look at the relevant arm with their own eyes.

It isn’t an allergic reaction though. I’ve had my ultra since it was released and it’s only now burning my skin. If it were an allergic reaction I would’ve been getting burned by it since it bought it. I only started getting burned since the last 3 updates


There are many substances that might potentially trigger allergies or irritations.

Those contributed by the materials of the watch among those in the soup surrounding each of us.

The photos posted here look a whole lot like dermatitis or another skin irritation.

But again, see your medical provider.

This is also my experience with apple too after my phone call with them. They asked if i was in any immediate danger, as soon as i said no. It seemed they couldn’t care any less and proceeded to end the call.

the watch was also sent off to their specialist repair centre and i was told nothing is wrong with the device and to wipe device just reinstall the update.

What did your doctor say?

I had thought it was just me and dermatitis until I saw this thread. I had exactly what people are saying here - been wearing an Apple Watch for over 3 years with no problems at all until suddenly one day last month I saw a massive red weal appear overnight. It’s taken over a month to heal and there’s still a red patch there.

The only thing I noticed was that the watch was unexpectedly nearly flat when I woke up so it does appear it drained the battery massively, which might fit with the sensor being stuck on full power.

I have had an Apple Watch for years and my current watch for well over a year. Suddenly the watch is making my wrists very sore, it looks like it’s burning my skin. It gets itchy and develops little blisters that seep. I switched wrists and it started doing it to the other wrist. I have seen other posts about this but no explanations as to why. I don’t think I’m going to be able to wear my watch anymore. I’m very disappointed as I track my steps, exercise and sleep. Any help out there?

I have been having same problem. My skin blisters leaving an exact imprint of the underneath of the watch case as ‘burnt’ circles

I reported to Apple some weeks ago but they show no interest in actually looking at my watch but their engineer team have pronounced no defect with the watch ( despite never inspecting it) They suggest going to my gp but I am no longer wearing the watch so no burn marks atm. Has anyone’s watch actually been inspected by Apple? I have no known allergies so feel like I’m being ‘fobbed off’

This happened to me too for the first time last night! I‘ve been wearing my watch for almost 3 years now and it is the first time this happened.


I am quite experienced with dermatitis etc, but this is very clearly and visibly a burn mark. Plus I woke up during the night when it happened and felt that my watch was very hot. My skin turned leathery over the reddened part. It is burning and frankly, I find it annoying that there are commenters in this feed dismissing what people are writing about their injuries. There are 55 people atm who clicked the me too button, so this seems to be a prevalent and frequent issue.

I am hoping this was a one off incident with my watch, but I won‘t be wearing it anymore during the night, in case it does happen again. It took me a while to wake up and notice it and my mark is pretty bad now. It looks like it will leave a scar.

Have been wearing my Apple Watch for over 1.5 years. Last night I awoke with pain and burning on my wrist. At first I thought ant bites or irritation from the band, but when I took the watch off I found a well demarcated area of erythema with a central area of small blisters also in a well defined pattern. I am a radiation oncologist so I have seen lots of skin reactions in the past 30 years and this is not the result of insect or chemical exposure. Seems to be due to energy deposition from the sensor.

I encountered a similar situation. The day after, I reached out to Apple, and our call lasted 56 minutes. They asked numerous questions and requested photos of my burned wrist. After that call, we scheduled another for two days later, and it just concluded. I was disheartened by how their investigation unfolded. They seemed unwilling to acknowledge that the issue stemmed from their product. From the outset, I explicitly mentioned that I wasn't seeking compensation; rather, I wanted them to be aware. As a concerned citizen who's noticed many teenagers and adults wearing Apple Watches, the safety of all users should be a priority. Unfortunately, Apple doesn't seem inclined to take responsibility for their customers. It's truly disappointing.

I bought one of the new watches in October. My wrist burns when I wear it, under the strap. I still have a mark a month after stopping wearing it. Apple told me to send it back to them but never gave me a correct address label so UPS won’t take it. I’ve sent numerous emails and have spent over £35 on calls to Apple. No idea what to do with it, I can’t wear it and have gone back to my Garmin. The times did an article about it yesterday but Apple wouldn’t comment!!

Yesterday I was at my local mall and my watch burnt me for the first time. I had a mark and after burn feeling for about 2 hrs after. I stopped in the Apple Store and they proceeded to tell me they have never seen this and kept asking if it was to right. I wear my band loose l. I told them this. And the watch does not get hot at all. I’m wondering what I need to do? I also put it back on later that night thinking maybe it was just from getting sweat, that was not the case it instead of on my wrist it went to my hand and I have a red line all the way across my hand.

Just bought the watch on the 6th of Jan 2024 for my daughter who was starting varsity. She only started wearing it in feb when she started varsity and few weeks later it burnt her on her wrist(round burn mark)


i took it to istore in South Africa and they made me answer lots of questions as if i was part of a survey, only to come back to me over a month later to say they will not exchange or refund me. Im so angry
