Keep Your Phone at Its Normal Operating Temperature
Your phone operates optimally at a normal temperature range. While it may feel warm or even hot under certain conditions, like charging, this does not affect your phone's lifespan or performance. If the phone does get too hot, it will stop charging and may even shut down automatically.
External factors that impact your phone's temperature
Although your phone may get warm, it has built-in safeguards to alert you and protect itself if it exceeds normal operating temperatures. Check out the CTIA's useful tips on safe phone usage for more information.
Here are some outside factors that can affect your phone's temperature:
Reasons your phone warms up:
Using your phone outside of normal operating conditions, which are ambient temperatures between 32 and 95 degrees Fahrenheit.
Placing your phone near a heat source, leaving it in a parked car on a hot day, or continued use in direct sunlight.
Using multiple apps for an extended period of time, or using processor-intensive apps such as gaming or GPS tracking.
Initial setup and data transfer from a previous device.
When your phone warms up
When you use features or apps that require more power or keep your phone on the charger for an extended amount of time, it may temporarily heat up. Here are some tips on what to do if it does heat up, and what you can do to avoid overheating.
Solutions for when your phone warms up:
Disconnect the phone charger and close any running apps until the phone cools down.
Try using a different USB cable. A defective cable can cause overheating.
Remove metal or magnetic material between the phone and the wireless charger.
Keep the phone's software updated.
Turn off Wi-Fi, GPS, and Bluetooth when you're not using them.
Delete unused or unnecessary files and apps.
Turn down the screen's brightness.
Do not use the phone for a while. If the phone is still overheated or hot, you should contact Samsung.
When your phone attempts to cool itself down
Caution: If the phone powers down due to overheating, let it cool off completely before you begin using it again.
Your phone is designed to regulate its operating temperature. If it gets too hot, you should remove your phone from any of the conditions listed above and let it cool down. In this situation, the phone may power off, close apps, temporarily stop charging, and/or dim the display. Your phone will also display notifications like the ones below that let you know your phone needs to cool down.
Note: Wording may vary by model.
