Tips to protect your Galaxy device from overheating

Do the following when the device heats up:

• Disconnect the charger from the device and close any running apps. Wait for the device to cool down and then begin charging the device again.
• It is recommended to use Samsung-approved battery, charger, and cable specifically designed for your device. Incompatible battery, charger, and cable can cause serious injuries or damage to your device.
• If the lower part of the device overheats, it could be because the connected USB cable is damaged. Replace the damaged USB cable with a new Samsung-approved one.
• When using a wireless charger, do not place foreign materials, such as metal objects, magnets, and magnetic stripe cards, between the device and the wireless charger.
• For models which support wireless charging feature, if the device is not placed on the exact center of the charging pad, the charging pad may overheat than normal. 

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. Close any running apps and do not use the device for a while.

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.
• Downloading large files.
• Using a large amount of data for syncing with the cloud, email, or other accounts.
• Using a navigation app in a car while the device is placed in direct sunlight.
• Using the mobile hotspot and tethering feature.
• Using the device in areas with weak signals or no reception.
• Charging the battery with a damaged USB cable.
• The device’s multipurpose jack is damaged or exposed to foreign materials, such as liquid, dust, metal powder, and pencil lead.
• Using apps that require more power or using apps for extended periods. (playing high-quality games, recording videos for an extended period, streaming videos, when connecting to a TV).
• Conflicts between running apps may cause the device to heat up. Restart the device.
• While multitasking (or, when running many apps in the background).
• If the device overheats or feels hot for a prolonged period, do not use it for a while. 

If you begin to feel uncomfortable due to the device overheating, stop using the device. When the device heats up, the features and performance may be limited or the device may turn off to cool down. The feature is only available on supported models.

• If the device overheats and reaches a certain temperature, a warning message will appear to prevent device failure, skin irritations and damages, and battery leakage. To lower the device’s temperature, the screen brightness and the performance speed will be limited and battery charging will stop. Running apps will be closed and all calling and other features will be limited, except for emergency calls, until the device cools down.

• If the second message appears due to a further increase of the device’s temperature, the device will turn off. Do not use the device until the device’s temperature drops below the specified level. If the second warning message appears during an emergency call, the call will not be disconnected by a forced shutdown.

Your device may heat up due to the environment in the following conditions. Use caution to avoid shortening the battery’s lifespan, damaging the device, or causing a fire.

• Do not store your device in very cold or very hot temperatures.
• Do not expose your device to direct sunlight for extended periods.
• Do not use or store your device for extended periods in very hot areas, such as inside a car in the summertime.
• Do not place the device in any areas that may overheat, such as on an electric heating mat.
• Do not store your device near or in heaters, microwaves, hot cooking equipment, or high-pressure containers.
• Do not use a cable whose covering is peeled off or damaged, and do not use any charger or battery that is damaged or malfunctioning.
