Why is my phone hot? | The Sun

CALLING the devices we rely on "phones" seems a bit of an understatement given how much they can do these days.

So much so, that, like us, they can get a bit hot and bothered when overloaded with tasks.

Why does my phone get hot?

Your phone can get hot for various reasons, like using applications that drain power, or using lots of apps at once.

It's not unusual for our device to become a bit warm when it's being worked hard, but if it persists it could be a more serious issue.

Common things that cause your phone to warm up are:

  • Gaming for extended periods
    • Gaming apps make use of your devices GPU and central processing cores which puts your device through quite a workout

    • Old apps
      • If apps aren't kept updated and have bugs, they can overuse the processor. Updates will fix bugs and ensure apps are working efficiently, and not putting the strain on your poor phone
      • It may have something to do with your device's settings. For example, leaving your screen brightness on full or using animated wallpapers, which will sap energy

        • Leaving it in the sun
          • May seem an obvious one, but many of us are so casual with our phones that they're left in all kinds of wacky places. Phones can easily overheat in the sun which drains battery. Water damage can also cause your handset to overheat.
        • Software updates
          • You may also find that your phone overheats after or during an update. This may be due to a bug that needed fixing, which meant your operating system need to use more power. Thankfully though, this is normally temporary, and shouldn't cause any long-term issues
