Summer is finally here. And while that means barbecues, beach days and time outdoors for many, it could also mean permanently damaged iPhones.
Most of us probably know that heat isnâ€™t great for computer systems. Most larger computers have a fan to try and mitigate some of the effects of overheating, but iPhones donâ€™t.
And while Appleâ€™s handsets are designed to protect themselves against and warn users about dangerous temperature changes, problems can still occur in particularly hot environments.
Hereâ€™s everything you need to know about keeping your iPhone safe in the heat.
âŒ iPhone Problems Caused By Heat
In most cases, iPhones can generally recover from overheating without any permanent issues. When an iPhone gets too hot, itâ€™ll automatically enter a â€œcool downâ€ mode and will give its user a temperature warning.
But extreme temperatures or prolonged exposure to heat can have lasting effects on your Apple handset â€” so itâ€™s smart to be cautious.
Apple itself notes that low or high-temperature conditions could cause your iPhone to â€œchange its behavior.â€ Its recommended ambient temperature for iOS device usage is between 0Âº and 35Âº C (32Âº to 95Âº F). Of course, it can become much hotter than that upper range in many parts of the world, or in enclosed spaces like the interior of a vehicle.
In the long term, this could result in damaged batteries. Apple says in a support document that â€œusing an iOS device in very hot conditions can permanently shorten battery life.â€
Heat can wreak havoc on lithium-ion batteries, causing a variety of issues like internal fluid evaporation, voltage component damage, or chemical reactions with the internal structure of the battery.
And that might be a best-case scenario. While lithium-ion batteries are generally safe, they can quickly become dangerous if damaged or significantly overheated.
âœ… Tips to Avoid Heat-Related Problems
- Donâ€™t leave your iPhone directly in the sun for extended lengths of time. Even on relatively cool days, direct sunlight can affect your iPhoneâ€™s internal temperature.
- Donâ€™t leave an iPhone in the car on hot days. We all know how hot enclosed cars can get on summer days â€” donâ€™t leave your pricey handset in one.
- Be mindful of where you keep your iPhone. Confined spaces like pockets can reduce your iPhoneâ€™s ability to cool off. It might also be smart to remove any external iPhone case if your iPhone is running warm.
- Consider forgoing intensive apps. Apps like video editors or graphically demanding games can cause your iPhone to heat up. That could pose a problem if itâ€™s already in a hot environment.
- Turn on Wi-Fi or enable Airplane Mode. Your device will get warmer if itâ€™s relying on cellular data to connect to the internet. GPS can also be a contributor to increasing device temperatures, so try not to use any location- or navigation-based apps.
- If you get a temperature warning, leave your device alone. Your iPhone will automatically enter â€œcool downâ€ mode if it gets too hot. You can facilitate this by keeping it out of the heat and refraining from using it.
- DON’T put a hot iPhone in the freezer. Rapid temperature changes can cause even more issues with your device â€” including permanent damage.
