How to Fix Samsung S22/S21 Overheating?

"Why is my phone overheating?" If you own a Samsung Galaxy S21, you've probably wondered about that a million times already. That isn't usually the case with a newly bought smartphone (particularly a flagship), but it is common with older handsets. Overuse of applications, apps operating in the background, and software difficulties can be the causes.  

Because your smartphone is an electronic gadget that needs a charger to function, it is normal to heat up sometimes during charging. If it's starting to heat up faster than usual, this is where we'll help you overcome your Samsung S21 Overheating problem.

Part 1: Fix Samsung S22/S21 Heating Issue

Here are some of the most sought-after solutions to your Samsung S21 heating issue.

Solution 1: Remove Galaxy S22/S21 phone cases

Your smartphone, like anything else, has to take a break now and again. You can speed up the cooling process of your phone by removing its cover, which is particularly beneficial when the weather is hot and humid. This will help the phone stay in its most 'natural' form and take the unnecessary load off its shoulders.

Solution 2: Check your charger

Your charger can have been defective or counterfeit. To avoid any heating issues, you must use a Samsung-certified adapter. Anything that is not Samsung-approved is not compatible with your phone. Not only can they cause your smartphone to overheat, but they can also lead it to malfunction. If you use the correct charger, the problem can be resolved.

Solution 3: Disable 5G and any other connectivity function

The usage of 5G when the phone is connected to a wireless network has been reported by several users as causing the handset to overheat. As a result, turn off mobile data and wait a few minutes before checking whether the problem persists.

If it's not heating, you can always ensure that the mobile data is switched off while connected to a Wi-Fi network. In addition, you can save a few critical megabytes of cellular data by using this method.

Moreover, turn off features that you aren't using regularly. This includes your Bluetooth, GPS, NFC, and other wireless technologies.

Solution 4: Restrict background data

Obviously, if you have 5-6 applications running in the background all the time, your phone will most likely overheat with time due to processor and RAM usage. That is why so many users have recently reported Samsung S21 Ultra heating issues. Try disabling background data use for applications and seeing if it helps solve the issue.

Step 1: Navigate to the Settings menu and select Connections.

Step 2: Then, pick Data usage from the drop-down menu.

Step 3: Choose the applications that make use of background data.

Step 4: Disable the use of background data.

Solution 5: Disable Multi-window

The overheating issue happens more often when many windows or picture-in-pictures are open. The fact that this is a big problem in a device that is meant to be excellent at multitasking is tricky.

As a result, deactivate multi-window mode, shut any running background applications, and lock the screen to save some power. Remove the gadget from its case and set it on a flat, ventilated surface to dissipate the heat.

Turn off the music and ambient sound if you're listening to music via headphones. Wait for 5 minutes and see if you see any changes in the phone's temperature.

Solution 6: Put unused Apps to sleep

The applications operating in the background might cause your phone to overheat. If you want to keep them from consuming your battery and dissipating heat, you can put them to sleep. Put the applications that you don't use too often into Deep sleep.

Step 1: Navigate to the Settings menu and choose Battery and device care.

Step 2: Choose Battery and then Background use limitations from the drop-down menu.

Step 3: Allow to Put any unused applications to sleep.

Step 4: Filter your applications and add them to the list of Deep Sleeping and Sleeping apps that you created before.

Solution 7: Use power-saving mode

As soon as you enable this option, it will switch off all background services known to deplete the battery and potentially cause the phone to overheat.

When you switch on the power saving mode, all your mobile's activities like network use, data synchronization, location checking, animation, brightness, and so on are suspended. This will help to keep your phone cool.

The following procedures should be followed to activate power saver mode:

Step 1: Navigate to the Settings menu.

Step 2: Select "Battery and device care" from the menu.

Step 3: Select Battery from the drop-down menu.

Step 4: Toggle the power saving mode on and off by tapping on it.

Solution 8: Update your Samsung S21

Overheating can be resolved by upgrading the software if a bug is the source of the problem. To update the software, follow the procedures outlined below:

Step 1: Navigate to the Settings menu.

Step 2: Select Software Update from the drop-down menu.

Step 3: To download and install the update, choose Download and Install from the drop-down menu (if available).

Solution 9: Factory reset your Samsung S21

You might try to factory reset your phone as a last option if none of the suggestions above successfully worked. Reset your phone to its original settings and see if it resolves the issue.

However, backing up all of your essential data is the ideal thing you would need to do first. And for that, we have MobileTrans as your best bet. It is one of the best software that can help you securely back up your data before factory resetting your phone. Here is how you can use MobileTrans:

Part 2: Tips to Avoid Samsung S21 from Overheating

Here are a few tips that can help you avoid the Samsung S21 Overheating issue.

• Do not use your Samsung phone when charging

Using your phone while it's charging simply isn't the wiser choice. It would help if you avoided it at all costs. Your phone while charging is already under one action; that is to re-charge the battery. On the other hand, it doubles up the load by discharging the battery, producing more heat when you start using it.

• Try to avoid hot environments

Ideally, the temperature range for your phone's typical operation should be between 0 degrees Celsius and 35 degrees Celsius.

If you use your phone in an environment where the temperature is too high, it will become prone to overheat quickly. Make sure to rest your phone from time to time and to allow it to cool down between uses.

• Do not run gaming for long periods

When you play games for an extended amount of time, the hardware components of your device get overworked and produce heat. Furthermore, the Samsung Galaxy S21 offers exceptional gaming performance.

• Keep your phone and apps up-to-date

An outdated device indicates that it lacks desired features and data that improve the device's functionality. As a result, if your Samsung S21 is out of date, seek an update in the device's settings. If the update is available, update the device as soon as possible.

Conclusion

The Samsung S21 Overheating issues are more widespread than you can imagine. Install the most recent updates, deactivate 5G while using Wi-Fi, and turn off multi-window mode to resolve the overheating issue. In addition, set your applications to Sleep or Deep sleep to save battery life. It's also vital not to use the gadget while charged. If you need to factory reset your phone, remember to backup your Samsung S21/S22 using MobileTrans first.
