9 Exposing It to Extreme Temperatures

Your iPhone, along with most electronics, is designed to be used within a specific temperature range. Apple’s recommended range is between 32º to 95º F (0º and 35º C). While a simple recommendation, it’s definitely advice that you should take — since extreme temperatures aren’t good for your device.

Normally, your iPhone will deactivate itself and send you a temperature warning when it’s hit a certain threshold protecting itself from damage. But that doesn’t mean damage can’t occur. Over time, charging or using your iPhone when it’s hot can lead to irreversible battery damage. On that note, it’s smart to remove your iPhone’s case before charging, too.
