Beat the heat

If you’ve ever used your phone outdoors on a hot day, you might know what it’s like to deal with overheating. Most smartphones are expensive, so naturally, you want to take care of the one you have to avoid buying a new one. Overheating can damage a phone’s battery and hardware, so it’s best to invest in a thermal case to use in hot weather. We rounded up the best thermal phone case options, with tips on how to protect your phone from damage.

What kind of phone do you have?

Before buying a thermal phone case, you first must consider what kind of phone you have. Some thermal phone cases have a universal design that fits nearly any phone, but others are for specific models.

For example, some cases only work with base model iPhones, such as the iPhone 13 and iPhone 13 Pro, while others have a larger build and can fit phones like the iPhone 13 Pro Max and Galaxy Note 10. Before purchasing a case, read the product description carefully to determine whether your phone is compatible.

Keeping the heat away

Thermal phone cases use insulation layers to deflect heat, so they have a bulkier build than traditional phone cases. Most thermal cases are pouches designed to hold your phone when you’re not using it and are the most effective at keeping your phone and preventing overheating. However, if you want to use your phone in hot weather, some phone cases use heat dissipation technology to filter out hot air and improve air ventilation.

What about water protection?

If you’re trying to keep your phone cool outdoors, there’s a chance you may encounter moisture in some form, whether you’re at the beach, hiking or cycling. The best thermal phone cases offer water resistance and typically keep your phone safe from splashing. However, thermal cases are not waterproof and can’t protect your phone from damage if it’s submerged in water.

Impact shock absorption

If you’re on the go and have your phone in a thermal case, it’s a good idea to ensure that it’s well-protected from accidental drops. Since thermal cases have a pouch design, they’re usually not made with sturdy materials like traditional ones that envelop your phone. However, the insulation acts as a cushioned layer and can offer significant impact shock absorption should you accidentally drop your phone on a hard surface.

Should I be concerned about cold-temperature protection?

Overheating is one thing and can damage your phone, but don’t overlook the importance of protecting your phone from frigid temperatures as well. Cold temperatures can damage your phone’s battery and hardware, but the insulation used in most thermal cases is also equipped to keep out the cold. That means you can use the same thermal case for sweltering and cold weather situations.

Stay connected

Because most thermal phone cases use several layers of insulation to keep out the heat, there’s some concern over whether it interferes with wireless signals. The best thermal phone cases do not affect connectivity and allow for stable cellular Wi-Fi, Bluetooth and Near Field Communication connections.
