TOPPING up your tan shouldn’t come at the cost of your tech.

Apple has cautioned customers that as temperatures peak, you may see an alert pop up on your iPhone saying it “needs to cool down before you can use it.”

Apple’s iOS and iPadOS devices perform best between 0º and 35º C (32º to 95º F).

Extreme high temperature conditions can permanently shorten battery life, according to Apple.

If your device is laying around in temperatures over 35º C, you’ll likely be met with the message above and will need to make an effort to cool it down.

While an iPhone showing this message may still be able to make emergency calls, it’s less than ideal.

But the tech giant has a three steps customers must do to get their device back up and running.

“To resume use of your device as quickly as possible, turn it off, move it to a cooler environment (away from direct sunlight) and allow it to cool down,” Apple said in a support forum on its website.

According to James Brown, tech expert and director of insurance firm  Protect Your Bubble, time is your friend when it comes to cooling.

So, it is smarter and easier to keep your phone in the shade and try to reduce the amount of time spent on it in a bid to get it working again.

“Avoid excessive use of your phone when outside in direct sunlight or operating at maximum screen brightness,” Brown explained.

“Playing high-performance video games or streaming videos for a long time can make even the latest smartphones heat up.”

The brighter and more active the screen is, the more power your phone battery is using, and the hotter 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,” Brown added.

“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.”

iPhone owners should also consider removing chunky cases that may restrict airflow around the device – so long as you’re not overly clumsy or travelling over hard floors any time soon.

Finally, don’t leave your device in your car, because temperatures in parked cars often exceed the 35º C limit, particularly in a heatwave.
