What If My Phone Gets Really Hot or Really Cold?
I live in Utah, and in our dry, desert climate, we can get temperatures over 100° in the summer and below 0° in the winter. I’ve seen the effect weather plays on iPhones when skiing on a below-freezing day and when leaving my phone in the hot sun by the pool.
The official operating temperature of an iPhone is generally between 32° and 95° Fahrenheit. When an iPhone reaches temperatures well outside this range for a certain amount of time, it will become unresponsive. In fact, usually when it’s too cold your iPhone will shut down completely; and, when it’s too hot, your phone will display a warning that it needs to cool down before you can use it.
To avoid these issues, keep your iPhone in the shade when out on a hot day. This will prevent the phone from becoming hotter than it should and will prevent damage to the device. In a cold climate, try to keep your iPhone in a warm pocket or shut it down if you know you will be outside for an extended period.
