How to Fix Galaxy S23 Overheating When Gaming

Intense 3D games can really heat up your Galaxy S23 during long play sessions. I know how frustrating it is when your phone gets too hot to hold comfortably and starts lagging.

Excessive heat can also drain your battery faster. Don’t worry – with a few tweaks and adjustments, you can keep your S23 running cool even when gaming heavily.

Fix Galaxy S23 Overheating When Gaming

Common Causes of Overheating

Gaming pushes the CPU, GPU, RAM and other components to their limits. This high demand generates excess heat, especially if there are inefficiencies or lack of cooling. Common culprits for S23 overheating when gaming include:

  • Graphically intensive games that max out the GPU
  • Having many background apps running
  • Brightness set to maximum
  • Clogged air vents or a tight phone case trapping heat
  • Bugs, glitches or processes hogging system resources
  • Hot ambient temperatures with no airflow

Solutions to Prevent Overheating

Here are the top troubleshooting tips to resolve overheating issues when gaming on your Galaxy S23:

Close All Unused Background Apps

Having too many apps running in the background consumes RAM and processing power. This added load makes it harder for your S23 to stay cool when gaming. 

Closing out any unused apps frees up resources so your phone can dedicate more effort to cooling itself. Always close all apps before starting a gaming session.

  1. Press the Recent Apps button. It’s usually the square button at the bottom left corner of your screen.
  2. Swipe left or right to find the app you want to close.
  3. Swipe up on the app to close it.
  4. You can also tap Close all to quit all apps at once.

Lower Screen Brightness

The display is one of the biggest battery hogs. Max brightness levels may look crisper, but they generate substantial heat. For cooler extended gaming, lower the brightness to around 30-50% rather than 100%. This reduces energy usage and thermals.

  1. Swipe down from the top of the screen to open the Quick Settings panel.
  2. Tap the Brightness icon.
  3. Drag the brightness slider to the left to lower the brightness.

Disable Unneeded Features

Features like Bluetooth, Wi-Fi, GPS and syncing use extra resources that contribute to overheating. Temporarily turning them off reduces background processes so your S23 can focus on your game’s graphics and cooling the SoC. Disable unnecessary features before you game via Quick Settings.

  1. Swipe down from the top of the screen twice to open the Quick Settings panel.
  2. Touch the respective tiles of features you want to disable.

Remove Phone Case

Phone cases are important for protecting your S23, but the downside is they trap heat against the chassis during intensive gaming. Removing the case allows more heat to dissipate away from the phone’s components by exposure to open air.

Update Software and Games

Developers regularly release bug fixes and optimizations that improve stability and efficiency when gaming. Update your games via the Play Store and install new Samsung/Android software updates. This reduces the chance of glitches causing resources to be misused and heat to build up.

To update the software:

  1. Go to Settings > Software updates.
  2. Tap Download and install.
  3. Follow the on-screen instructions.

To update games:

  1. Open the Google Play Store app.
  2. Tap your profile picture in the top right corner.
  3. Tap My apps & device.
  4. Tap Updates available.
  5. Tap the Update all button next to the game you want to update.

Use Power Saving Mode

Power saving mode throttles CPU speeds, limits screen brightness, and reduces background app activity. This decreases the phone’s overall power consumption, allowing it to stay cooler. 

Turn it on before starting a gaming session, but performance may be reduced.

Here are the steps on how to use Power Saving Mode on your Galaxy S23:

  1. Go to Settings > Battery & device care > Battery.
  2. Tap Power saving mode.
  3. Toggle on Power saving mode.

Power Saving Mode will reduce the performance of your phone and limit vibration, location services, and most background data to help improve battery life. You can also customize the settings for Power Saving Mode to make it work the way you want.

Factory Reset Device

If all else fails, a factory reset will wipe any bugs or processes causing excessive heat, restore optimized default settings, and give you a fresh start. Make sure to backup data first, as this erases everything.

  1. Make sure your phone is turned on.
  2. Go to Settings > General management > Reset > Factory data reset.
  3. Tap Reset device.
  4. Enter your PIN or password, if prompted.
  5. Tap Reset again.

Your phone will start resetting. This process may take a few minutes.

By proactively managing device resources, utilizing cooling accessories, ensuring updated software, and resetting your S23 when needed, you can enjoy smooth lag-free gaming without overheating headaches. Play on!


  1. Why does my Galaxy S23 get hot when gaming or using apps?

    Excessive heat is usually caused by intensive 3D games and apps pushing the CPU, GPU, and RAM to their limits. This high resource demand generates more heat, especially if the phone lacks proper airflow or has background processes running.

  2. Is it normal for the S23 to get a bit warm?

    Yes, it’s normal for the S23 to get slightly warm when performing demanding tasks like gaming, streaming videos, or using navigation. A moderate temperature increase indicates components are working as expected. Overheating occurs when it gets uncomfortably hot to hold.

  3. Does overheating damage my S23?

    Extreme overheating can potentially degrade the battery faster, cause performance throttling, and damage internal components over time due to thermal stress. It’s best to avoid sustained high temperatures by troubleshooting cooling issues.

  4. How can I keep my S23 cool when gaming?

    Closing background apps, reducing screen brightness, using a cooling accessory, updating software, wiping the cache partition, and factory resetting can all help prevent overheating. Proper airflow and removing thick cases are also beneficial.

  5. When should I be concerned about overheating?

    Noticeable sluggishness, warm air from the earpiece, apps crashing unexpectedly, or the phone getting too hot to hold comfortably when gaming are signs of problematic overheating requiring troubleshooting.
