his has been a concern for me, as I rely on my watch for various tasks and functions throughout the day, and I don’t want it to malfunction or become damaged due to overheating.

Fortunately, I have researched a few possible solutions that may help fix your watch 4. I will share these solutions with you in this article and hopefully help you get your Galaxy Watch 4 back to functioning properly.

Let’s get started!

Why Does Your Galaxy Watch 4 Overheating

Here are the possible reasons for your Galaxy Watch 4 overheating issues. However, before going deeper, you have to take a quick look at its possible reasons.

Low cellular signals
Unnecessary or sideloaded apps
Software bugs, install the latest software update.
Protective cases stop exhausting.
Incomplete installed & running in background applications

Cellular Signals

While using the Galaxy Watch 4 LTE to make calls over the mobile network, we noticed that the watch experienced a significant increase in temperature when it was in areas with weaker reception.

This issue also occurred when the watch was connected to mobile data. The watch was not paired with a smartphone via Bluetooth during our testing.

This overheating issue seems to be more prevalent in areas with lower reception or when using mobile data rather than when connected to a smartphone through Bluetooth.

As a smartphone, the Galaxy Watch 4 LTE also uses extra energy and power to improve its reception strength in weak signals.

This increases the power consumption and causes the watch to heat up and also drain its battery faster.

The compact size of the Watch 4 makes it difficult for it to dissipate heat quickly, leading to overheating issues.

Software Update

Sometimes this issue occurs while the watch software is in sustained work. Such as when the watch software updates over WiFi or directly LTE without connecting the watch via Bluetooth to your phone.

Although installing or updating the apps can actually cause this issue in a few cases. On the other hand, it might be a software error or bug.

And Samsung should pay attention to fixing this bug. Address Samsung customer support with this issue, and they will release the latest update with the issue fixed.

Sideloaded & Unnecessary Apps

Another reason can be installing or using unsupported apps on your Watch 4. That leads your watch to get overheated.

Although installing mobile APKs on your Galaxy watch, such as WhatsApp, and Google Assistant Go, can be helpful for you but are not optimized for using the Watch 4 processor.

So, using these kinds of apps on your Galaxy watch will cause an increase in your watch temperature.

As with mobile phones, your Watch 4 comes with pre-installed apps, and few of them we don’t need. So these apps can cause the watch to overheat.

Background Updates

Apps running in the background will be the reason for Watch 4 the overheating issue; they continually utilize your watch sensors, antennas, and processor.

Background app updates or installation also increases WiFi or cellular connection use. So, all these apps cause excessive use of Watch 4 components and cause overheating.

Get in Touch With Heat

If the watch is placed closer to the heat exposure, it is common to get the watch to overheat. And the other reason will be while using the watch in extremely hot weather and the direct sunlight can overheat the watch.

How to Fix Watch 4 Overheating Issue

These are the possible solutions that will fix your Watch 4 overheating problem.

Move to Area With Better Signals

When using the watch in areas with no better signals, you should move to the other areas with good Cellular or internet signals.

Because the watch consumes a lot of power to get better signals and causes overheating. Before making calls or using the Internet over the watch, ensure three signal bars are in your Watch 4.

And then, check the watch to verify if the overheating issue is fixed. If the issue still persists, you should read the further following steps.

Remove Protection Case

Another possible solution is removing the protection cases from the watch. However, the protection case is a good choice for protecting the watch from dents and scrapes.

Although these cases prevent your watch from losing heat in its surroundings. So, removing these cases is the solution, especially while you are receiving calls or using the Internet.

Connect Watch to Phone

If the watch is disconnected from the phone, there is a chance of the watch overheating. The connection loss can be checked by a small icon at the top of your Watch’s screen.

So, when your watch disconnects from the smartphone, it will be forced to utilize the Internet or mobile data, causing it to quickly warm the watch up if any update starts running in the background.

Update Software

If your Watch 4 is running on an outdated software version, that can cause the watch to malfunction. You should check to ensure the watch software is up to date.

However, outdated software will be the main reason for overheating the watch. To fix this software bug, you should instantly install the latest version.
