Can heat damage iPhone screen?

We’ve all been there. You leave your iPhone in the sun on a hot summer day and return to find it overheating. But while we may worry that the heat has caused damage to the device, the truth is that our phones and tablets are designed to withstand extreme temperatures. But that doesn’t mean you should leave your phone in the sun for too long. The heat can still cause damage to the iPhone’s internal components, and in some cases, it can cause the screen to crack.

Temperature Range Effect on iPhone
32°F to 95°F (0°C to 35°C) Safe for use
96°F to 113°F (35°C to 45°C) May cause temporary malfunctions
114°F to 131°F (45°C to 55°C) May cause permanent damage

Apple states that the iPhone should be operated at temperatures between 32°F (0°C) and 95°F (35°C). Anything outside of this range can cause the device to malfunction or even cause permanent damage. For instance, if the device is exposed to temperatures of 114°F (45°C) or higher, the battery may suffer permanent damage. This could mean that your iPhone’s battery will not last as long as it should.

It is also important to note that while the heat can damage the internal components of your iPhone, it can also cause the screen to crack. This is because the heat causes the iPhone’s metal frame to expand, which can put stress on the glass and cause it to crack. So even if the heat does not cause any permanent damage to your phone, it can still cause your screen to crack.
