Why Your Samsung Galaxy Z Fold 3 or Z Flip 3 Overheats

Your Samsung Galaxy Z Fold 3 and Z Flip 3 Overheats. Is it, however, occurring on its own or as a result of a particular app? Is it because you’re watching a lot of videos or because it’s just too hot outside? It’s challenging to establish the exact cause of your smartphone’s overheating.

When a phone becomes too hot, it begins to slow down. It may shut down automatically until it has cooled down in some circumstances. You don’t want to miss a crucial call?

It’s worth trying to consider what hot is and what it isn’t before moving on. Under normal circumstances, your Samsung Galaxy Z Fold 3 and Z Flip 3 should not be hot. If your phone gets hot to the extent of almost burning you, then you’ve got a problem.

Warm, on the other hand, should not be interpreted as hot. It’s natural to feel somewhat warmer after 15 minutes of gaming. However, if your phone displays an overheating alarm or feels unusually hot to the touch, you should look into it.

To troubleshoot, you’ve probably already closed a few apps or rebooted your device. Perhaps you’ve even looked up a few error messages on Google.

You’ll almost always come across a list of the same old reasons for your phone overheating:

  • The brightness of your display is set too high.
  • Your Wi-Fi has been turned on for an excessive amount of time.
  • You’ve been playing too many games (often accompanied by the warning “it’s not a game console”).

However, these arguments are only applicable to older phones. For any of these reasons, no smartphone on the market today should overheat. It’s most likely due to various factors if your brand new Samsung Galaxy Z Fold 3 or Z Flip 3 is overheating. Of course, it doesn’t matter what brand of phone you have.

Keep reading if you want to know why your Samsung Galaxy Z Fold 3 and Z Flip 3 are getting hot and how to fix them.

Possible Causes of Overheating on the Samsung Galaxy Z Fold 3 and Z Flip 3 and how to fix them

Overheating during and after initial setup

If your phone gets hot after the initial setup, you don’t need to worry, as this is a regular thing. Initial setup can be quite resource-intensive, and some heating is to be expected.

Give your phone some time to cool; if the phone does not cool after a few hours, go to the next step.

Overheating After Updating

Some Users complained that their Galaxy Z Flip 3 or Z Fold 3 overheats after updating to the latest OS. Here is what one of the users facing this issue has to say;

My fold 3 started to be hot near camera like im playing games but all the time. It started after i updated a system yesterday. When i pick up the phone and turn on screen its becoming even warmer. Any ideas?

If you notice the issue started after you updated to the latest One UI before the overheating started;

Check your battery status to see any app running in the background consuming battery (up to 20% in the background). If you find any, clear the cache and restrict background usage.

Operating phone in Hot Temperture

The ambient temperature of a place where you can operate your phone should not exceed 35 degrees Celcius or 95 degrees Fahrenheit. When you run your Samsung Galaxy Z Fold 3 or Z Flip 3 in areas where the temperature is too high, then your phone gets hot. The best thing is to avoid a hot environment.

Apps with Abnormal Usage

This is the most typical reason your Samsung Galaxy Z Fold 3 or Z Flip 3 is overheating. There are apps running in the background that consumes a lot of energy.

  • Close all background apps by tapping the recent key, then tapping the Close all button.
  • You can also identify apps on your phone that consume power a lot by going to the Battery Status. If these apps are not essential, uninstall them.
  • Enable safe mode and check whether the overheating issue disappears. Your phone will only run native apps in safe mode, and all third-party apps will be temporarily disabled.
  • To Enable Safe Mode, Hold down the power button until the Power off icon appears. Hold down the Power off icon until the Safe Mode icon appears. To restart your phone in safe mode, tap the Safe Mode symbol.
  • If the overheating goes away in safe mode, it was most likely caused by a third-party program. Identify the app(s) and remove them from your phone.

Phone Cases or Cover

Your Samsung Galaxy Z Fold 3 and Z Flip 3 are powered by the Samsung Galaxy 888 chipset. This chipset is very powerful and can generate heat easily. Your smartphone does not have a heat sink like your laptops and computer does.

Samsung created some form of cooling through the casing, and the phone dissipates heat out through the case.

If you are using any phone casing or cover with your Galaxy Z flip 3 or Z Fold 3, try removing the phone cases or cover. Use your phone without the casing for two days to see if the problem suffice.

Some cases trap heat created by the phone, which makes the phone overheats (happens even with light use).

Charging and using your phone

When you are charging and operating your phone at the same time, you might experience phone overheating. Allow your phone to charge completely before pressing it.

Also, the fault could be from a faulty or bad charger. Make sure the charger you’re using is Samsung-approved. Anything that isn’t Samsung certified should be avoided at all costs. They can cause not just overheating but also harm to your phone. If you use the correct charger, the problem may go away.

Other Fixes for Samsung Galaxy Z Fold 3 and Z Flip 3 Overheating Issue

Lower Display Brightness

The Z fold 3 and Z flip 3 peak brightness is 1200nits. Try to lower your phones’ brightness. The brightness of the phone can drain the battery if it is set to the highest.

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

These services aren’t required all of the time. It doesn’t make sense to keep these services running while you go to bed, for example. They not only drain the battery, but they also heat up the phone, diminishing battery health and, as a result, battery life. When you’re not using them, turn them off. Directly from the Quick settings panel, you can turn them off.

Also, the standard of 5G is not yet settled. If you have 5G support in your area, it’s likely not faster than 4G LTE. Turn off 5G and use 4G LTE while browsing, as 5G could be draining your phone’s battery.

Update your phone to the Latest Operating System

Update to operating systems always contains security, privacy, and bug fixes. If there are any recent OS update available for the Galaxy Z Fold 3 and Z Flip 3, update them.

Turn on the power-saving mode

When you enable this option, it will disable all background services that consume the battery and potentially cause your phone to overheat. When you turn on the power saving mode, all activities like network usage, data syncing, location check, animation, brightness, and so on are disabled. Your phone will remain cool as a result of this.

Use the instructions below to enable power saver mode:

  • Go to the Settings menu.
  • Select Battery and Device Care from the drop-down menu.
  • Click Battery.
  • Toggle on Power saving mode by tapping on it.

Wipe the cache partition on the system

Whether the problem persists after attempting the solutions mentioned above, consider erasing the system cache partition to see if the overheating issue is resolved. Use the instructions below to wipe the system cache partition:

  • Switch off your phone.
  • Connect your phone to your computer via a USB cable.
  • Wait until the message indicates that your phone is being charged before proceeding.
  • Press and hold the Volume Up and Power keys at the same time.
  • Hold both keys down until the Android Recovery menu appears.

  • To choose, use the Power key.
  • To select, hit the Power key after pressing the Volume down key to highlight Yes.

  • To restart the device, press the Power key.

Perform a factory reset on your phone.

If none of the other suggestions work, you can factory reset your phone to return it to its original settings and see if it solves the problem. However, make a backup of all of your vital data and contact information beforehand. Use the steps below to perform a factory reset:

  • Switch off your phone.
  • Connect your phone to your computer via a USB cable.
  • Wait until the message indicates that your phone is being charged before proceeding.
  • Press and hold the Volume Up and Power keys at the same time.
  • Hold both keys down until the Android Recovery menu appears.
  • Navigate to Wipe Data/Factory Reset by using the Volume Down key.
  • To choose, use the Power key.
  • Press the Volume down key to bring up the Factory data reset menu, then choose it with the Power key.
  • Reboot system now is highlighted once the reset process is completed.
  • To restart the device, press the Power key.
