So, you have got your hands on the latest Samsung Galaxy S21, S21+ or S21 Ultra but are facing overheating issue? That hurts and makes you worried. After all, you did pay a high price for this coveted device!

Don’t panic! This is common and there are some quick fixes that you can use to resolve the issue. Here is a list of few simple things that you can do to reduce the overheating on your Samsung Galaxy S21, S21+ or S21 Ultra. Read on!

How to fix overheating problem on Samsung Galaxy S21, S21+ or S21 Ultra

1. Try to avoid hot environments

The ideal temperature range for the normal functioning of your phone is between 0 degree Celcius to 35 degrees Celsius. Your phone will tend to overheat if you are using your phone in a place where temperature is too high. Make sure to rest your phone periodically and allow it to cool down.

2. Remove phone cases or covers

Try not to use covers or cases that do not have sufficient space for dissipating the heat. If the case is trapping heat generated by your phone (which normally happens even on mild use), the phone will overheat. Experiment by removing the cover to know whether it is the cover that is causing the problem or not.

3. Check your charger

Is your charger faulty or fake or a cheap replacement? You need to make sure that you are using a charger which is Samsung certified. Anything that is not Samsung certified is just not for your phone. Not only can they cause overheating, but they can also damage your phone. Use a proper charger and the issue may disappear.

4. Close all background apps

When too many apps run in the background, your phone can quickly heat up. Forcefully closing them can help to cool down your phone. To close background apps, follow the steps below:

Tap the Recent key to view all running apps.

Then tap the Close All button to close all these apps at once

5. Remove problematic apps

Some faulty apps can cause cause overheating problem. Try enabling safe mode and see if the overheating problem goes away. With safe mode enabled, your phone will run only native apps and all third party apps will be temporary disabled.

Here’s how to turn the safe mode on.

Press and hold on the power button until you see the Power off icon

Press and hold on the Power off icon until you see the Safe Mode icon

Tap on the Safe Mode icon to reboot your phone in safe mode

If the overheating disappears in safe mode, then mostly likely some third party app was the culprit. Try identifying that app(s) and uninstall it from your phone.

6. Turn off Bluetooth, 5G, mobile data, WiFi, hotspot, location services, etc.

These services are not always needed. For instance, when you go to sleep, keeping these services running doesn’t really make any sense. Not only do they eat up the battery, but they also heat up the phone, significantly reducing battery health and hence, battery life. Turn them off whenever you don’t need them. You can turn them off directly from the Quick settings panel.

7. Use power saving mode

When you turn this feature on, it will disable all those services that run in the background and drain the battery and even lead to your phone heating. Activities like network usage, data syncing, location check, animation, brightness, etc. are all stopped when you turn on the power saving mode. This keeps your phone cool.

To enable power saving mode, use the following steps:

Go to Settings

Tap on Battery and device care

Tap on Battery

Tap on Power saving mode and toggle it On

8. Update software

If there is some bug causing the overheating problem, updating software can solve the problem. Follow the steps below to update the software:

Go to Settings

Tap on Software Update

Tap Download and Install to download and install the update (if available)

9. Wipe system cache partition

If the issue doesn’t resolve with the above tips, you can try wiping the system cache partition and see if that clears the overheating problem. To wipe system cache partition, use the following steps:

Turn off your phone

Connect your phone to the PC via USB

Wait until the message shows your phone is being charged

Press and hold the Volume Up key and the Power key.

Continue to hold both keys until Android Recovery menu options appear

Press the Volume down key and navigate to Wipe cache partition

Press Power key to select

Press the Volume down key to highlight Yes, then press the Power key to select

When the process is complete, Reboot system now is highlighted

Press the Power key to restart the device

10. Reset all settings

Using this option will put your device settings and the settings of all the apps to their original settings. This will rule out any software conflict that can lead to an overheating issue. To do this, use the following steps:

Go to Settings

Tap on General management

Tap on Reset

Tap on Reset all settings

Tap on Reset settings button

Type in the passcode if prompted

Tap Reset to confirm the reset

11. Factory reset your phone

If none of the above tips work, you can factory reset your phone as the last resort to restore your phone back to its original settings and see if that fixes the problem. But before you do so, back up all your important data and contact information. To do a factory reset, use the following path:

Turn off your phone

Connect your phone to the PC via USB

Wait until the message shows your phone is being charged

Press and hold the Volume Up key and the Power key.

Press the Volume down key and navigate to Wipe Data/Factory Reset

Press Power key to select

Press the Volume down key to highlight Factory data reset, then press the Power key to select

When the reset process is complete, Reboot system now is highlighted

Press the Power key to restart the device
