How to prevent the overheating of your Galaxy device

Last Update date : Dec 27. 2021

Whether you're using a phone, tablet, smartwatch, or earbuds, all Galaxy devices have a set temperature range where they operate at their best. While they may feel warm under certain conditions, like charging, this does not affect the devices' lifespan or performance. However, these devices may temporarily generate heat on various occasions. Thus, we suggest taking precautions to avoid placing your device under these circumstances.

The following factors may affect the temperature of your Galaxy devices:

  • Using your devices in an environment outside of normal operating conditions (between 32 and 95 degrees Fahrenheit).
  • Placing your devices on/near a heat source, such as leaving them in a parked car on a hot day or continuously having them exposed to direct sunlight.
  • Running multiple apps for an extended period of time or using processor-intensive apps for gaming, streaming, and GPS tracking.
  • Using an incompatible, defective, or non-Samsung certified charger and / or USB cable.
  • Initial setup and data transfer from the previous devices.
  • System or firmware updates.

As your device generates heat, you may see warning messages. Please be aware that access to certain features/functions may temporarily freeze as a mean to protect the device.


  • Signs and results may vary by device and model.

Here are some solutions for what to do if your Galaxy devices generate heat.

Solution 1

Turn off the Wi-Fi, GPS, and Bluetooth functions when not in use.
In addition, reduce the screen brightness of your device.

➊ Pull down the 'Quick panel',
then turn off 'Wi-Fi' and 'Bluetooth'

➋ Turn off ‘Location’

➌ Minimize the brightness

Solution 2

Optimize the phone to minimize the heat caused by processor intensive apps that drain the battery.

➊ Go to ‘Settings’ and
select ‘Battery and device care’

➋ Tap ‘Optimize now’

➌ Tap ‘Done’

Solution 3

Unused apps in the background may heat up the device.
To resolve the issue, try ‘Background usage limits’.

➊ Select ‘Battery and device care’

➋ Select ‘Battery’

➌ Select ‘Power saving’

➍ Turn on ‘Power saving’

➎ Select ‘Background usage limits’

➏ Turn on ‘Put unused apps to sleep’


  • Please ensure your device has the latest app updates by checking regularly.
  • Screen images and menu items may vary depending on your model and software version.
  • 'Power saving’ limits the usage of network, data syncing, location info in the background.


What does
'Power saving' do?

- Turns off ‘Always on Display’
- Decreases brightness by 10%
- Limits CPU speed to 70%
- Turns off 5G
- Limits app use and Home screen

Smartphones may generate heat as their slim designs are not optimized for airing out heat or due to their excessive battery consumption. Both the device and the charger can generate heat while charging. The temperature may even feel warmer when charging with ‘Super Fast Chargers’ or wireless chargers.

Take the following actions if your device generates heat while charging.

Disconnect the charger, and close all running apps. Wait until the device cools down, then start charging again.

If the problem persists, try charging with another Samsung-authorized charger and USB cable. Please be aware that the charging port may generate heat due to a damaged or incompatible charging cable.


  • The warranty for the smartphone battery is a year. If a manufacturing issue is identified by the Samsung Service Center within the warranty period, it will be repaired or replaced free of cost. If the issue is identified as caused by the user, even within the warranty period, or any issue is discovered after the warranty ends, there may be a charge to you for the repair.
  • When using a wireless charger, make sure there are no metal substances, magnets, or credit/transit cards between the device and the charger.

Charge with a Samsung Authorized Wireless Charger,
