Prevent Your Phone From Overheating This Summer

Keep Your Phone From Overheating This Summer

Summer is here. It’s time to be outside enjoying the sun! Whether you’re headed to the beach or out to the park for an afternoon, summer is all about getting out with friends and family.

Phone overheating is a major problem at all times of the year, but especially in the hot summer months. Knowing how to stop a phone overheating, or how to cool down a phone if it does overheat, can prevent lasting damage to your device. 

Why Do Phones Overheat?

Phones overheat for a number of reasons, the most common cause being exposed to high temperatures. Direct sunlight can cause overheating, as the phone’s internal temperature rises in response to outside temperatures. Leave a phone on a car dashboard in full summer sunlight, and it’s going to overheat pretty quickly. 

How you use your phone can also increase its internal temperature. For instance, your phone may overheat if:

  • You run too many apps, causing the battery to drain faster and release heat
  • You use the phone constantly, raising the temperature
  • You leave the phone charging after it’s fully charged
  • You run apps that place high demands on the battery while it’s charging

What Happens When a Phone Overheats?

When a phone overheats, it may force a shutdown to prevent damage and not restart until the temperature drops. Overheated phones also experience faster than normal battery drainage. 

If the temperature of the phone gets too high, internal components may be damaged, and the phone may not restart after a forced shutdown. In extreme cases, overheating can melt the phone’s central processing unit. It’s even possible for a phone to explode when exposed to extreme heat, although this is a rare occurrence.

How To Stop a Phone Overheating

There are a number of ways to prevent phone overheating. The easiest is to minimize the phone’s exposure to direct sunlight or locations where it may be exposed to heat sources. Don’t leave the phone in your car on a hot summer day, for instance, and use it in shady, cool areas as much as possible. 

How you use your device also influences overheating. Try the following strategies:

  • Keep app use to a minimum: Turn off unused apps so they do not place demands on your battery. Your phone won’t need to work as hard, heat buildup will be reduced, and your battery will last longer.
  • Reduce your screen brightness: The brighter your screen, the harder your phone has to work, which generates heat. Keep your screen brightness low and purchase an anti-glare screen cover so you can see the screen in environments with bright light. 
  • Turn on airplane mode: Airplane mode turns off nonessential features and places less stress on the device’s battery. You’ll still be able to use basic functions.
  • Take the case off: Yeah, we know — removing a phone case increases the risk of physical damage to your phone. Cases act as insulators, however, trapping heat within the phone. If you think your phone is overheating, take off the case and put it somewhere safe and cool. The phone’s heat vents will work more efficiently, so the phone will cool faster. Once it’s cool, put the case back on for safety. 
  • Use the right chargers: Cheap, no-name chargers are not designed specifically for your phone and can result in overheating. Use chargers designed specifically for your brand of phone.
  • Don’t use phones while they charge: Playing games or streaming movies while your phone charges puts extra pressure on your battery. Under such circumstances, phone overheating can occur quickly.
  • Charge phones on hard, flat surfaces: Don’t plug in your phone and leave it charging on a soft surface like a bed mattress, couch, or pillow. Such surfaces have insulating properties and will trap heat in the phone. 

How To Cool Down a Phone That’s Overheating

If your phone is overheating, turning it off and putting it somewhere cool and shady is the best way to reduce the internal temperature quickly. While it may be tempting, do not put the phone in the refrigerator or freezer. Exposing phones to sudden temperature extremes can cause damage, and placing a phone in a fridge or freezer can cause moisture condensation inside the case, which can cause serious damage.
