Why your iPhone may stop working in hot weather – and how to avoid it

With temperatures in both the UK and US soaring this month, people have flooded outside to enjoy the sunshine.

But while you might remember suncream to protect your skin, you might not be so aware about the dangers to your iPhone .

Several users have seen warning messages appearing on their iPhones, cautioning that the iPhone needs to cool down before they can use it.

But what happens when your iPhone gets too hot?

Here we explain what’s really going on – and what you can do to avoid it.

What temperature does your iPhone work at?

According to Apple, iPhones work in areas where the ambient temperature is between 0º and 35º C (32º to 95º F).

Temperatures outside of this range might cause your iPhone to change its behaviour in an attempt to regulate its temperature.

What happens when your iPhone gets too hot?

Using your iPhone in temperatures beyond 35º C (95º F) can have a serious effect on the battery life.

On Apple’s website , it says: “Using an iOS device in very hot conditions can permanently shorten battery life.”

This battery life shortening happens to protect the internal components and prevent them from overheating.

Other changes you might notice include slow charging, a dimming of the display, and a weak cellular signal.

The camera flash will also temporarily be disabled, while performance in graphic-intensive apps will slow.

Additionally, if you’re navigating, the device might show this alert and turn off the display: "Temperature: iPhone needs to cool down."

Thankfully, navigation still provides audible turn-by-turn directions.

How can you prevent your iPhone from overheating?

If you see the temperature warning screen, there are several ways to cool down your iPhone.

Apple explained: “To resume use of your device as quickly as possible, turn it off, move it to a cooler environment, and allow it to cool down.”
