Protect your tech: How to keep your phone cool during the heatwave 

Our phones are very rarely away from our hands, but during a heatwave, it’s all too easy for these devices to get dangerously hot, which affects battery life and may cause the device to temporarily shut down.  

With most of the UK being hit by a heatwave this weekend as the Met Office predicts highs of 30 degrees, here are some top tips to ensure your phone stays healthy this weekend.  

It goes without saying but keep your phone in the shade and try and reduce the amount of time spent on your phone. By keeping the screen off and engagement with the device reduced, it will impact the heat produced. You can also activate battery-saver mode to limit app functionality.  

You could also look to remove any additional cases or covers you may use to aid airflow and prevent temperatures from rising to higher levels. But be careful, you don’t want to drop, scratch, or smash your device without its protective casing on it.   

Avoid excessive use of your phone when outside in direct sunlight or operating at maximum screen brightness. Playing high-performance video games or streaming videos for a long time can make even the latest smartphones heat up.  

The brighter the screen is, the more power your phone battery is using, and the more battery is consumed, the more heated your phone can become.  

If you’re outside and you need to check your phone, seek shade nearby and lower the brightness of your screen.  

If, even after turning off power-hungry apps, you find your phone is still heating up, turn on your phone’s built-in power-saving mode. This mode will close background apps, reduce brightness and enable faster screen locking.  

Even if your phone comes with the highest rating of water resistance, it’s a bad idea to submerge your phone in cold water to forcibly cool down.  The same applies to leaving your phone inside a fridge or cooler.  

Doing so will cause condensation from inside your phone, which will damage the device in the long run. Just let your phone cool down in its own time.
