How can I prevent my Samsung Galaxy device from overheating

Last Update date : Apr 28. 2026

Galaxy devices may heat up during heavy use or charging, especially with gaming or multiple apps. Managing usage, settings, and environment can help prevent overheating.

What causes overheating

  • Using the device in very hot or direct sunlight conditions
  • Running multiple or heavy apps like games or GPS
  • Using incompatible chargers or cables
  • Performing updates or data transfers

Note:

  • Signs and results may vary by device and model.

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’.

Note:

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.

Note:

  • 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.
