Your Galaxy Watch is essentially a small computer strapped to your wrist. So, feeling a little warmth is not necessarily a sign that something is wrong. However, there is a big difference between your watch feeling slightly warm while in use or even while charging and it feeling so hot that you want to take it off. Unfortunately, some users have experienced the latter issue, with one Galaxy Watch 7 owner posting online how his watch had become uncomfortably hot while he was wearing it. This can happen if your watch is using more resources than usual, so check if your battery is draining faster than usual.
Unfortunately, there is no single explanation for why your Galaxy Watch might be overheating. Samsung says that CPU-intensive apps, GPS tracking, software updates, direct sunlight, and even incompatible chargers can increase the device’s temperature. So if you’ve noticed that your watch is overheating a lot, it might be worth sitting down and evaluating what chargers you’re using and whether you have a lot of apps running.
Your apps and settings could be making your Galaxy Watch hot
One of the first places to look is what your Galaxy Watch actually does while you’re wearing it. For example, prolonged GPS use, running multiple applications, and even initial setup data transfers can temporarily put more strain on the hardware and generate more heat. If you just updated your watch, you should expect it to also run hotter because it used more resources to download and install the update.
If you noticed the problem after installing an app, you can try temporarily removing it to see if that’s the problem. It might also be helpful to close any apps you’re not currently using and make sure your watch and apps are up to date. Some features, such as continuous health tracking, GPS, voice wake-up, and always-on display, may also increase the heat, depending on how you use it. You can always try turning off some essential Galaxy Watch features to extend your battery life a little more. It could also reduce CPU usage and help your watch run cooler.
Power saving mode could be another useful test. You can enable it through the Galaxy Wearable app under Watch Settings > Battery > Power saving. You don’t need to leave it on all the time, but if the watch runs much cooler with power saving mode active, that could suggest that a non-essential app is contributing to the problem.
Why your Galaxy Watch heats up while charging
You’ve probably noticed that your Galaxy Watch heats up while charging. Some heat is expected while charging, and we suggest following charging best practices to help keep your watch’s temperature low. However, if you notice your watch getting extremely hot while charging, unplug it and let it cool down immediately before putting it back on the charger.
If you encounter this problem, first check the charger itself. Samsung warns that incompatible or faulty charging accessories may cause excessive heat. It might be worth trying another compatible Samsung charger to rule out a charger problem. Also avoid charging the watch in direct sunlight or in an already hot place. Figuring out the best time to charge your Galaxy Watch based on your environment can be very helpful.
Most importantly, if you get an overheating warning, don’t ignore it. Samsung says the Galaxy Watch will begin to limit its functions as its temperature rises, and if this continues, it may eventually shut down. If the watch remains too warm to the touch after you stop using or charging it and allow it time to cool, contact Samsung Support and stop wearing the watch immediately.
