When using your Galaxy S21 FE 5G, you may notice that the smartphone can get hot.

You can take a look at this troubleshooting guide from Seeking Tech to see how you can prevent, and potentially fix, overheat issues with this Samsung device.

How to prevent your Samsung Galaxy S21 FE 5G from overheating

In order to prevent your Galaxy S21 FE 5G from overheating, you can try taking the following precautionary steps:

1. Make sure you use your phone within a temperature range of 32°F to 95°F (or 0°C to 35°C).

2. You should also avoid prolonged exposure of your Galaxy S21 FE 5G to direct sunlight.

3. Furthermore, you shouldn’t place the smartphone near any heat source, such as a space heater, inside of a sauna or on the car dashboard on a hot day.

4. If you have multiple apps opened for an extended amount of time, then these combined will take up a lot of resources, causing your phone to work extra hard and generating heat as a result.

5. Some applications, such as videogames and those that require GPS tracking, are really intensive and will cause your phone to heat up quickly.

6. Having Bluetooth, Wi-Fi and/or Location connections enabled even if you aren’t using them will also cause the phone to heat up.

7. Moreover, we recommend that you don’t use your Samsung Galaxy S21 FE 5G while it is charging.

8. When recharging your phone, make sure you don’t cover it or you will end up trapping the heat from being able to properly dissipate.

9. A non-Samsung charger or defective charger can cause the Galaxy S21 FE 5G to heat up as well.

What happens when the Galaxy S21 FE 5G overheats

If you continue to let your Samsung Galaxy S21 FE 5G continue to rise in temperature, then the smartphone will automatically take action on its own before the heat could cause permanent hardware issues.

The device should send you a message about it overheating. It will then try to cool down by dimming the display screen, closing apps, stopping the battery from recharging or even completely powering off.
