Why does my Samsung Galaxy Watch 4 keep overheating?

Let’s look at all the possible issues that might be causing your Samsung Galaxy Watch 4 to overheat,

1. Low Cellular Signal:

The Galaxy Watch 4 may overheat in areas with weak cellular reception. LTE usage without a Bluetooth-connected smartphone leads to increased power consumption, generating heat and causing battery drain. Cooling mode and airplane mode activation are necessary to manage excessive heat.

2. Software Updates:

During software updates, the Galaxy Watch 4 can experience temperature spikes when updated over WiFi or LTE without a Bluetooth connection. Certain app updates can also induce overheating. Maintaining a stable Bluetooth connection during updates is crucial to prevent excessive heat.

3. Sideloaded Applications:

Sideloading unsupported apps onto the Galaxy Watch 4 can lead to uncontrolled temperature escalation. Installing only apps explicitly designed for WearOS smartwatches is recommended to avoid overheating risks.

4. Background Apps and Updates:

Background apps on the Galaxy Watch 4 strain its components, leading to overheating. Continuous WiFi or cellular usage during background updates intensifies the problem. Monitoring and managing background apps can help prevent overheating issues.

Now that we know all the issues that might be causing the overheating, it’s time to look at all the possible solutions,
