. 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 

. 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.

Check your charger

Is your charger faulty or **bleep** 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

. 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 once5. 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 iconPress and hold on the Power off icon until you see the Safe Mode iconTap 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 SettingsTap on Battery and device careTap on BatteryTap 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 SettingsTap on Software UpdateTap 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 phoneConnect your phone to the PC via USBWait until the message shows your phone is being chargedPress and hold the Volume Up key and the Power key.Continue to hold both keys until Android Recovery menu options appearPress the Volume down key and navigate to Wipe cache partitionPress Power key to selectPress the Volume down key to highlight Yes, then press the Power key to selectWhen the process is complete, Reboot system now is highlightedPress the Power key to restart the device10.
