The Samsung Galaxy Watch 4 is a popular smartwatch known for its many amazing features. However, one issue that users may encounter with the device is overheating. This can be an annoying problem that can hinder the normal use of the watch. In this article, we will take a close look at the causes of Samsung Galaxy Watch 4 overheating and practical ways to fix it.

1. Excessive usage: Using your Samsung Galaxy Watch 4 excessively can cause it to overheat. If you use your watch for extended periods, you will notice that the back of it gets hot. The more you use it, the hotter it gets. This is because the watch comes with a small battery, which produces less heat than a battery in a larger smartwatch. The battery life may be long, but it isn’t infinite.

To fix this problem, you should reduce the usage of your watch. Avoid running multiple applications simultaneously, or leaving the Wi-Fi, GPS, or Bluetooth on when they are not needed. If you have a habit of turning on the Samsung galaxy watch 4 always on display feature, disabling this feature can help reduce the watch’s temperature. Also, try to keep your watch out of direct sunlight or a hot environment. You can dim the screen backlight or turn it off when not in use.

2. Software issues: There might be a software issue that is causing your Samsung Galaxy Watch 4 to overheat. If you have recently updated to the latest software and noticed your watch has been heating up since, the problem is likely related to the update.

You can fix this by restoring the previous software version or uninstalling the application that caused the issue. To do this, go to your Galaxy Wearable app, select the software update and then click on the “download and install” button. If this doesn’t work, you can try factory resetting your watch to its default settings.

3. Battery issues: Another reason why your Samsung Galaxy Watch 4 may be overheating can be battery-related. If the battery is worn out or damaged, it may not be able to power the watch properly, causing it to overheat. Also, using a third-party charger or an incompatible charger can cause damage or result in a defective battery.

You can prevent this issue by using only the original charger that came with your watch for charging. Always monitor your battery use and don’t overcharge it. When the charge is full, disconnect it from the charger. Try to keep your watch at a temperature of around 25°C to extend its battery lifespan. You can get a new battery from a Samsung store or a certified retailer, and the battery will be installed and tested for free.

4. Hardware issues: A defective hardware component can also cause your Samsung Galaxy Watch 4 to overheat. If the watch is brand new and still covered by the warranty, you can take it to the manufacturer for repair or replacement. If not, you may need to visit a certified technician who has the experience required to handle hardware issues.

In conclusion, overheating is a common problem with Samsung Galaxy Watch 4. However, a few simple preventive measures can go a long way in fixing the issue. Reducing usage, addressing software and battery issues, and handling defective hardware components properly can help you enjoy your smartwatch without overheating problems.

How to Check the Temperature of Your Watch

If you suspect that your Samsung Galaxy Watch 4 is overheating, the first thing you should do is check its temperature. Here’s how:

1. Use the Sensor Push App

The Samsung Galaxy Watch 4 has a built-in temperature sensor that you can access using the Sensor Push app. This app lets you view your watch’s temperature in real-time and alerts you if it gets too hot. Here’s how you can use the Sensor Push app:

  • Download and install the Sensor Push app on your Samsung Galaxy Watch 4.
  • Open the app and wait for it to connect to your watch’s temperature sensor.
  • Once connected, you’ll be able to see your watch’s temperature in real-time.

The normal operating temperature for the Samsung Galaxy Watch 4 is between 0°C and 35°C (32°F and 95°F). If your watch’s temperature goes above this range, it may overheat and malfunction.

2. Use a Third-Party App

If you don’t want to use the Sensor Push app, you can also use a third-party app like CPU Temperature to check your Samsung Galaxy Watch 4’s temperature. Here’s how:

  • Download and install the CPU Temperature app on your Samsung Galaxy Watch 4.
  • Open the app and wait for it to connect to your watch’s temperature sensor.
  • Once connected, you’ll be able to see your watch’s temperature in real-time.

3. Check the Back of Your Watch

Another way to check the temperature of your Samsung Galaxy Watch 4 is to simply touch the back of the watch. The back of the watch is where the temperature sensor is located, so if it feels unusually hot, the watch may be overheating. Alternatively, if the back of the watch feels cool or normal, the watch’s temperature is likely within the normal range.

Advanced Tips to Troubleshoot Overheating


The Samsung Galaxy Watch 4 is a great wearable, but like any electronic device, it can suffer from performance issues. Among these issues is overheating, which can easily happen if you exert your watch to do too much at one time or if you wear it and indulge in rigorous physical activities such as running or other strenuous exercises. The good news is that you don’t need to give up getting the most out of your Galaxy Watch 4, even if it tends to overheat. Here are some advanced tips that you can try to troubleshoot the issue:

1. Turn off Always-On Display Mode

The Always-On Display mode keeps the watch face active all the time, which can lead to overheating issues. You can try turning off this feature to preserve your watch battery and fix the overheating problem. To turn it off, go to the “Display” tab in your watch’s settings, and turn off the “Always-on” display option.

2. Disable GPS and Bluetooth

The Galaxy Watch 4 comes with GPS and Bluetooth functions that can drain the battery and cause overheating issues. If you are not using these functions, then it is better to disable them to prevent overheating. To do this, swipe down from the top of your watch’s screen to access the Quick Settings menu, and tap the GPS and Bluetooth icons to turn them off.

3. Avoid Running Apps in the Background

If you notice that your watch is heating up, it may be because of too many apps running in the background. To avoid this, always keep your watch clean and try to close apps you are not currently using. You can close apps by swiping the screen from left to right and tapping the “Close All” button.

4. Reset Your Watch


If none of the above methods seem to work, you can try resetting your device to its factory settings. Resetting your watch can help fix any software issues that may cause overheating. Before you proceed with the reset, make sure you back up all your data and remove your Samsung account from the watch. To reset your watch, head to the Settings App > General > Reset and tap the Factory Reset option.

5. Check for Firmware Updates

If you are experiencing overheating issues with your Galaxy Watch 4, it is worth checking to see if there are any firmware updates available for your device.
