How to Fix OnePlus 9/9 Pro overheating Issue

Not less than a month after OnePlus released its all-new flagship lineup, the OnePlus 9 and 9 Pro, the company already released three software updates for these devices. These updates included the newest Android security patches and various optimizations and improvements for the system, connectivity, and cameras on the two smartphones.

However, there is one significant flaw with the OnePlus 9 Pro that has yet to be resolved. According to Android Police, the OnePlus 9 Pro has an aggravating overheating issue that renders the phone unusable for a short period. The problem is most noticeable when taking photos or movies with the phone. Still, user comments on the OnePlus Community forums suggest it can also occur when conducting other strenuous tasks.

If your Oneplus 9 or 9 Pro overheats, the first step to take is to update the device to the latest version. This action should fix the overheating issue, but don’t worry if you have done this and still have overheating problems. This article explains how to fix OnePlus 9 and 9 Pro overheating issues.

Why Your OnePlus 9 and 9 Pro Overheats

Your OnePlus 9 and 9 Pro 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 OnePlus 9 and 9 Pro should not be desirable. 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 OnePlus 9/9 Pro is overheating. Of course, it doesn’t matter what brand of phone you have.

Possible Causes of Overheating on the OnePlus 9 and 9 Pro 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 pretty 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 OnePlus 9 and 9 Pro overheats after updating to the latest OS. Here is what one of the users facing this issue has to say;

I’m making this post to see if other oneplus 9 pro users are having the same issue. I was hoping for the overheating issue to be fixed after the updates, but several updates later, the phone constantly overheats. The camera gets pretty much unusable sometimes, recording videos is a fantasy since it overheats after one minute. It constantly overheats while I’m on a video which is extremely frustrating. After paying so much money for this device that I really want to love, I’m having second thoughts now. I wonder if other people have the same issues and if so, is there something we can do to alleviate this? Is this a hardware defect or a software issue? Thanks in advance.


If you update to the latest Oxygen OS, v11.2.3.3, and still have the same issue;

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 OnePlus 9 and 9 Pro 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 OnePlus 9 and 9 Pro is overheating. Apps are 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

The Snapdragon 888 5G chipset powers your OnePlus 9 and 9 Pro. This chipset is very powerful and can generate heat quickly. Your smartphone does not have a heat sink as your laptops and computer does.

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

Try removing the phone cases or cover if you are using any phone casing or cover with your OnePlus 9 and 9 Pro. Use your phone without the container 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 set entirely before pressing it.

Also, the fault could be from a faulty or wrong 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 OnePlus 9 and 9 Pro Overheating Issue

Lower Display Brightness

The OnePlus 9 and 9 Pro peak brightness is 1300nits. 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 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 OnePlus 9 and 9 Pro, 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.
  • Navigate to Wipe cache partition by pressing the Volume down key.
  • To choose, use the Power key.
  • To select, hit the Power key after pressing the Volume down key to highlight Yes.
  • Reboot system now is highlighted after the operation is finished.
  • 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.
