Heatwaves have become more frequent over the years, with hot seasons now lasting 46 days longer than they did in the 1960s, according to data collected by the U.S. Environmental Protection Agency. The scorching temperatures can be great for traveling, but the sun also makes it easier for your smartphone to overheat, which can lead to future damage, such as your phone automatically turning off or, worse, stopping working altogether.

PHOOZY Thermal Phone Case

For those who don’t want to part ways with their current phone case, this thermal pouch will provide a cooling effect without having to tear off the flashy casing. What’s notable about this design is the spacesuit-inspired material, which can reflect over 90% of the sun’s heat away from your device, according to the official product description. It comes in two sizes: medium or large, and the case is compatible with both iPhones and Samsung devices, for added versatility.

Does a heat-dissipating phone case work?

While a phone case won’t completely prevent your phone from overheating, the cooling materials (silicone and thermoplastic polyurethane) will help regulate the temperature of your device and prevent it from reaching alarming levels of heat. The main purpose of a heat-dissipating phone case is to regulate heat by providing airflow and heat-dissipating materials to lower the phone’s temperature.

In addition to providing a layer of protection for your phone, you can also prevent it from overheating by not leaving it in direct sunlight or in a car on a hot day. Apple warns that smart devices that exceed 95 degrees may be at risk of damage.
