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.
You can also try following the steps below to clean background running apps more prominently. To do so:
- Open the Settings app on your Samsung Note 20 / 20 Ultra.
- Tap on Battery and Device Care > Tap on Optimize Now.
- Open the Settings app again > Go to Battery and Device Care.
- Go to Memory > Select the background apps that you want to close.
- Now, select Clean Now, and reboot the device to refresh the system.
2. Force Restart your Device
The second thing you can do is simply restart your device forcefully so that it can clear out temporary glitches on the handset. To do this:
- Press and hold the Volume Down + Power keys for at least 10 seconds.
- It will forcefully shut down your device and power on again.
- Once the Samsung logo appears on the boot screen, make sure to release both keys and wait for the device to boot up.
- This should fix the crashing issue on your Samsung Note 20 / 20 Ultra. However, if the problem still persists then you can jump into the next method.
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:
- Go to the Home screen > Swipe up or down on the screen.
- Tap on Settings > Make sure to scroll down and select Device care.
- Choose Battery > Tap on Power mode.

- Open the Settings app again > Go to Battery and Device Care.
- Go to Memory > Select the background apps that you want to close.
- Now, select Clean Now, and reboot the device to refresh the system.
4. Uninstall Battery Consuming Apps or Games
Sometimes issues with the rogue third-party apps or games may cause overheating or draining of your battery. It’s better to remove all the battery-hungry apps or games from your handset to easily fix multiple issues whatsoever.
- Tap and hold the app icon whatever you want to delete.
- Select Uninstall and confirm the process. [If it’s showing App Info then tap on it and select Uninstall]
Do the same steps for each application whatever you need to remove from your device.
5. Update System Software
In some cases, updating the software version can easily resolve multiple issues with the system glitch or content streaming freezing issue. To do that:

- Tap on Software update > Tap on Check for Updates.
- If there is an update available, make sure to tap on Download and Install.
- Now, you’ll need to wait for the device to finish the updating process.

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.
- From here you can either install app updates individually or you can tap on Update All to install all app updates automatically.
- Once all app updates are installed, you can simply reboot your handset to check for the issue.
7. Don’t Overcharge the Battery
Try not to overcharge your handset because it can eventually drain the battery or decrease the lifespan of the battery. Don’t let your device charge overnight. Once the battery level is around 20-30% make sure to charge it up to 80-90% and use it. No need to fully charge the device if the device is new or you don’t use the handset extensively.
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:
- Go to the device Settings menu > Tap on Apps.
- Now, tap on the 3-dots vertical menu on the top right corner.
- Then select Reset app preferences > Tap on Reset.
- Once the reset process is done, you can reboot your device to apply changes.
12. Wipe Cache Partition
The chances are high that somehow the cache partition data on your handset becomes corrupted or outdated enough. In that case, it’s recommended to wipe out the cache partition data from your Galaxy Note 20 series to improve system performance and clear out temporary glitches. To do this:
- Make sure to switch off your phone > Press and hold the Power + Volume Down keys for around 8 seconds.
- When the Samsung logo appears on the boot screen, you should release both keys and wait until the device enters recovery mode.

- Finally, press the Power key to select Reboot system now.
