Fix: Samsung Note 20 / 20 Ultra Overheating Issue

To recall, the Galaxy Note 20 model is backed by a 4,300mAh battery with 25W fast charging support and the Galaxy Note 20 Ultra model has a 4,500mAh battery with 25W fast charging technology. However, the device overheating issue may appear due to overcharging, exposing the device to direct sunlight for a while, streaming content or playing games, or even talking with someone via a call, etc can trigger battery overheating a lot.

It will eventually occur the battery draining and unexpected device behavior apart from app crashes, slow performance, the slow boot time of the system, longer loading time, and more. Sometimes background running apps can also occur overheating issues that we can’t deny. Whereas the overheating issue can also happen due to the internal hardware fault because thermal pads for cooling with vapor chambers & copper thermal heat pipes aren’t working.

1. Close Background Apps

First of all, you should try closing all background running apps on your handset to easily increase the system performance. Except for the necessary background running apps, make sure to close other ones by following the steps below.

  • From the Home screen, tap on the Recent Apps key to view all apps that are still running in the background.
  • Make sure to tap on Close All to end or force close all background apps.

3. Enable Battery Saver and Optimization

It’s also recommended to enable the battery saver mode for maximum optimization of the power consumption. Although this feature will block some functions on the device to reduce battery draining, you’ll find it useful enough while the battery is low or it’s draining too much. To do so:

6. Install Pending App Updates

You should also try installing all the pending app updates on your device before jumping to any other conclusion because an outdated or corrupted app version can trigger several issues with the system performance whatsoever. To do so:

  • Open the Google Play Store app on your device > Tap on the hamburger menu icon from the top-right corner.
  • Now, check for the available app updates on your handset.

7. Don’t Overcharge the Battery

8. Avoid Exposing the Device to Direct Sunlight

Do not keep your Galaxy Note 20 or Note 20 Ultra directly under the sunlight for a long time because it may get overheated and can reduce the battery strength easily. Keep it under a normal temperature to cool it down if it gets overheated.

9. Don’t Use While Gaming or Calling (Multitasking)

Make sure to avoid using your handset extensively while gaming or calling as multitasking because it can seriously impact the battery life. Your battery health and life cycle will go down faster. Try not to use your device heavily while charging the battery.

10. Try Disabling Unused Apps or Services

Make sure to disable the unused apps or services manually if you haven’t used them for the last couple of months. That means even if you’ve installed some apps or they come preinstalled, you don’t find them useful enough to use. In that scenario, just disable those apps.

  • Press and hold the specific app icon to see a pop-up menu.
  • Tap on App Info > Select Disable. [If in case, you don’t want to uninstall]

For future reference, if you want to open or use any app that has been disabled, simply tap on the app icon again to activate it. That’s simple!

11. Reset App Preferences

Sometimes improper app configuration or settings can easily trigger system performance issues apart from the battery draining issue. It’s worth mentioning that the battery draining is one of the results of overheating. Try resetting the app preferences to the factory default by following the steps below:
