Why Smartphones Overheat and How to Prevent Your Phone From Overheating

By Mabel Ekperen

Why does my phone overheat? It’s a question that we’ve all asked ourselves at one point or another, especially if it’s happened to you in the middle of an important task. Whether it’s an Android, iPhone, or Windows phone, the device is likely similar to your computer, with a processor and other internal hardware doing a lot of the heavy lifting. This can take up energy and cause phones to heat up. Here are some causes and tips for preventing your smartphone from overheating:

Why Smartphones Overheat

There are a number of reasons why your phone might start to overheat, but the most common cause is when you use it for too long at a time. The battery is the main reason for this, as it produces heat as it discharges energy. If you’re playing a game or watching a video on a screen that’s bright and large, this will also make your phone work harder and therefore produce more heat in return.

Charging Your Phone

Charge your phone in a cool place. Heat is one of the main reasons that phones overheat, so you should always try to charge them in places where the temperature is cooler. Charge your phone overnight. You don’t necessarily have to wait until you’re dead on your feet before charging up, but if you do decide to charge it right before bedtime and then leave it plugged in all night, make sure that you turn off any unnecessary features like Wi-Fi or Bluetooth these can help save power and prevent overheating as well.

Use a quality charger and cable when charging your device; this will ensure that they work efficiently while also preventing damage to them through overuse or improper use (i.e., using an older charger with worn-out wiring).

Using Your Phone in a Hot Environment

If you’re using your phone in a hot environment, it’s especially important to make sure that you don’t use your phone for too long. Try to avoid using your phone in the sun or in a car. Also, never use your phone in a sauna or hot tub.

Keeping Your Phone in Your Pocket

The next most common way to experience overheating is by keeping your phone in your pocket. You may be surprised to learn that pockets get hot! In fact, the average body temperature of a person is 98.6°F (37°C), and anything higher than that can create heat on its own.

Keeping your smartphone in your pocket when you’re sitting down will cause its internal temperature to rise rapidly if it’s near the back of your thigh or buttock regions, so don’t do it! If you really want to keep it handy while in an air-conditioned environment, try placing it somewhere where it won’t be constricted by clothing and exposed directly to cool air flow—like on top of a vent or out at room temperature.

How to Prevent Your Phone From Overheating

Turn off your phone. It’s a simple solution, but turning off your phone is the best way to prevent it from overheating. If you don’t plan on using your phone for a while or overnight, then turn it off.

Use Airplane Mode: If an app is causing your smartphone to overheat and die, then try using a type of “offline” mode called “airplane mode.” This disables all radios on the device so that no calls or texts can be sent or received while allowing other functions like GPS and camera usage when appropriate.

Keep it Cool: Try leaving your phone in someplace cooler than normal like another room when charging overnight

  • Take good care of your battery.
  • Charge your phone when it’s half full.
  • Do not leave your phone charging overnight
  • Don’t overcharge your phone.
  • Turn off unnecessary apps.
  • Turn off location services.
  • Turn off Bluetooth.
  • Turn off Wi-Fi.
  • Turn off auto-updates.
  • Turn off auto-play on videos, music, and games (this will keep the device from constantly checking for updates).
  • Check your settings to see if your phone can automatically sync with iCloud or Dropbox, and turn it off if it’s set to do so automatically (this may be under “iTunes & App Store,” depending on what device you’re using).
  • You might also consider turning off notifications for social networks like Facebook and Twitter until you get a chance to check them manually. It’s easy for these programs to send out dozens of notifications in one day!

Don’t leave your phone in a hot car, out in direct sunlight (or any other bright place), or exposed to water or moisture for an extended period of time if at all possible this will shorten its lifespan and damage internal components like the battery or motherboard.

Use Airplane Mode More Frequently

The first step to keeping your phone cool is to turn off all of the radios that are constantly emitting electromagnetic waves. This means disabling Wi-Fi, Bluetooth, and location services, turning off battery-sucking apps like Facebook or Instagram, and turning off push notifications, auto-sync, and background processes on all apps.

Turning off NFC will also help keep your phone from overheating. This technology allows you to connect two devices by simply touching them together but it can be an unnecessary drain on battery life (and therefore heat). GPS is another culprit while helping you navigate with turn-by-turn directions, it’s also a major source of heat for smartphones because it requires extra energy from the processor in order to update location information every second or so. Turning this feature off could eliminate as much as 10% of the heat produced by your device.

Smartphones overheat for a variety of reasons, but there are steps you can take to help prevent overheating, some of them include:

  • Avoid keeping or leaving your phone in a hot car
  • Don’t charge your phone overnight.
  • Don’t leave your phone on the bed.
  • Don’t leave your phone in your pocket or bag while it’s charging.
  • If you’re using it outside on a hot day, keep it in an air-conditioned area as much as possible (or just avoid using it at all).

Even if you follow all of these rules and still experience overheating problems, that doesn’t mean there isn’t anything else you can do to help prevent them, it just means that there are other factors at play besides what we’ve already discussed.

One thing to consider is how much you use your device; depending on how much time you spend browsing the internet, playing games, or watching videos (especially in high definition), more frequent use may cause phones to heat up faster than usual even if everything else seems fine.

In Conclusion

Smartphones are complex machines that run many different processes simultaneously. Heat is a natural byproduct of any electrical process, but some phones do have issues with overheating. There are solutions to these problems as we have discussed earlier. If your phone gets too hot, first make sure it’s not in direct sunlight or in a hot car for extended periods of time.

Next, try restarting your phone if it frequently overheats and then uninstalling any apps you think may be causing the problem; this should resolve most issues. If it doesn’t, contact customer support for additional help or take your phone back to the store as soon as possible (since heat can cause irreversible damage).
