Factors that may cause your phone to heat up

If your Galaxy phone gets warm during use, there are several reasons this may be the case. When you use features or apps that require more power or use them for extended periods, your device may temporarily heat up due to increased battery consumption. Also, during wireless charging or fast charging, your phone may feel warmer to the touch. The following are examples of situations in which the device may overheat. Depending on the functions and apps you use, these examples may not apply to your model.

  • During the initial setup after purchase or when restoring data.
  • When downloading large files.
  • When using apps that require more power or using apps for extended periods.
  • While multitasking or when running many apps in the background.
  • When using a large amount of data for syncing with the cloud, email, or other accounts.
  • When the device is placed in direct sunlight.
  • When using the mobile hotspot and tethering feature.
  • When using the device in areas with weak signals or no reception.
  • When charging the battery with a damaged USB cable.
  • When the device’s multipurpose jack is damaged or exposed to foreign materials, such as liquid, dust, metal powder, or pencil lead.
  • When you are roaming.

Note: Results and symptoms may vary depending on the device and model being used. Some solutions will not apply to certain devices.
