Ways to fix Samsung Galaxy S4 overheating issue

  • First, you need to update all the apps by going to Google play store as corrupted applications and the apps which are not updated can create this error. So update all the apps, which show a message ready to update. Re-check the apps after updating, and if you find any apps showing as not updated even though you have updated it, delete it.
  • Faulty SD-card might be a strong reason behind this problem, so format the SD-card and then insert it in your phone to find out if the problem is reduced to some extent. Take a backup of all the data before formatting.
  • If you are facing the overheating issue due to the software-related problem, then OTA updates can fix the Samsung Galaxy S4 overheating issue.
  • Check the bloatware and background processes in your Galaxy S4 as sometimes it is the software to be blamed for such overheating issue and not the battery. In case the high number of background processes keeps running in the background continuously, it normally results in overheating of the battery and fast battery drain as well. Find bloatware apps and disable them and stop background processes. Also, go to the Settings > More > Battery to check what are the apps that are utilizing unusual amount of battery and delete them from the device.


  • Close the apps that you are not using as many apps that run at a time can overheat your phone. But if you don’t notice any change after closing the apps, then it might be a hardware problem, and you have to contact the service center.
  • Water damage can also create this overheating issue. If this is the case, the service center is the only way to get rid of this issue.
  • Disable the Bluetooth, GPS and also dim the screen.
  • If the phone is getting heated while using ear piece then you need to put your phone in CPU power saving mode. For that go to Settings > My Device > enable Power saving mode. Now you need to click on the power-saving mode tab and it will open a new page. There you will see three options, among them CPU power saving tab that needs to be turned on.
  • Putting your Galaxy S4 into the Airplane mode could be useful if the phone is getting overheated while charging. The reason is when the phone is charging the battery is in use continuously, searching Wi-Fi signals or network and in such a situation overheating problem occurs in some phones.


So check all these steps and if the problem still exists, then contact your dealer or service provider and ask for a replacement.

  1. Thanks for trying to help but I didn’t understand the first part of your instructions, can you please elaborate a little more and break it down in layman’s term?
    Faulty SD card format? What is a format? How do I back up the data before formatting? What is an OTA and how do I update this? And lastly, what is a bloatware and how do I check this?
    Thank you…….

    1. Hello Helen 🙂 I will try to explain the things you asked a bit more 🙂
      First, a faulty SD card meaning that your SD card is not working properly or that some files you have stored on it are corrupted and causing the problem. Formating means erasing the data on your SD card.
      To back up your data, you can read the following guide:
      Updating the software on your device can fix many problems, and you can go with OTA (over the air). This means you can connect to a Wi-Fi network, and then update the software. Here is the guide you may read:
      When you purchase a new phone, you will see many pre-installed apps. You probably won’t use many of them and even though they are not harmful in any way, they can slow down your phone as they usually use a lot of storage space on the phone. These apps can’t be removed, but can be disabled. Every phone comes with a different set of pre-installed apps. However, not all the apps should be disabled, because you may stop the app that is essential for the performance of your device. The pre-installed apps you SHOULD NOT REMOVE are the ones that have an Android logo (pic) right next to their name. To disable an app, go to Settings > Applications > All and then see the list of apps there. Tap on the app you want to disable, and click Disable. Do this only if you are sure this won’t affect the performance of your device.
      To close apps and processes that run in the background, hold the Home button for a few seconds. The list of apps will open. Tap and hold the app you wish to close and then tap Remove from list, or swipe to the right to close the app. Or, if you want to close all apps that run in the background, tap Remove all icon that is located in the bottom-right corner of the screen.
      I hope this helps 🙂

      1. Thank you Dana for taking the extra time to help me with my problem I am having with my phone. I understand it now that you explained it to me in detail. Thank you again for sharing your knowledge in repairing cell phones.
