Reasons why smartphones overheat

Overheating warning on iPhone

Hot weather and outdoor trips can cause your smartphone to heat up. If the temperature gets too high, your device may stop charging or display an overheating warning.

In other cases, overheating will cause the phone to shut down or break completely. Therefore, users need to find out the cause and how to prevent it properly, helping the smartphone operate stably.

According to CNET, some reasons why smartphones heat up include leaving the phone in direct sunlight, using it in a high temperature environment, or using it while charging.

Other causes include a faulty charger or battery, faulty software, malware-infected operating systems, and cases that prevent heat dissipation.

In most cases, overheating on smartphones is not a serious problem. When this happens, the back of the phone will overheat, reducing performance, charging speed or signal quality.

Overheating can also cause the phone to shut down or stop working with the flash. In more serious cases, the smartphone can be permanently damaged, forcing the user to get a repair, replace the battery, or buy a new phone.

There are several solutions to help prevent overheating on your phone. First, avoid leaving your smartphone in direct sunlight for long periods of time.

Dangerous places to leave your phone include beaches or car cabins. Unless it is an emergency, keep your device out of direct sunlight, such as a pocket or backpack.

Users should not charge their smartphones while watching movies for long periods of time.

Not only sunlight, you should also avoid leaving your phone in a high temperature environment for too long. For example, if you leave your car exposed to the sun, the cabin temperature can reach 60-70 degrees Celsius after an hour.

According to Apple, the optimal operating temperature of smartphones is 0-35 degrees Celsius. To avoid overheating, the environment around the phone should be kept between -20 and 45 degrees Celsius.

CNET also added some ways to prevent your phone from overheating. First, you should not turn on apps that require high performance processing (games, movie viewing apps...) while charging.

In addition, it is necessary to update the operating system and applications on the smartphone to the latest version. In some cases, faulty software can cause overheating.

Finally, avoid using poor quality chargers or cables. Faulty or poorly designed accessories can cause your phone to overheat, leading to serious problems like battery swelling or fire.
