Overheated iPhone Warning!

In cold winter months or hot summer days, it can happen for an iPhone to be pushed out of its operating comfort zone. With the onset of Winter, I was reminded about this sensibility, just a few days ago. This is an article about how to handle extreme temperature warnings that appear on the screen of your iOS devices.

According to Apple, iPhones have an operating temperature ambient situated between 32° and 95° Fahrenheit, that’s 0° and 35° Celsius.
The manufacturer also provides information about a non-operating temperature interval ranging between -4° to 113° F, that’s -20° to 45° C.
If your device’s temperature drops below or rises above its operating limits, iOS will prompt you with a warning message and ask you to warm it up or cool it down.

Operating, Non-Operating & Dangerous Temperatures
This means that you can SAFELY store your iPhone or iPad, but NOT use them in an environment measuring between -4° and 31° F (-20° and -0.5° C) for the lower end. The upper limits being 96° to 113° F (35.5° to 45° C). Temperatures below -4° F (-20° C) and above 113° F (45° C) can permanently damage the functionality of your gadgets. The first thing that comes in mind is the built-in rechargeable lithium-ion battery, that could see its properties altered if exposed to such extreme temperatures.

iPhone Low Temperature Warning
frozen iPhoneIf you operate your iOS device in an environment that measures temperatures below 32° F (-0° C), for a long time, you risk to get a low temperature warning from iOS. You’ll be asked to warm up your device before you can start using it again. This can happen, for example, if it’s frosty outside and you forget your iPhone in your car, or you hold your device outside your pockets for too long.
To solve it, please warm up your phone gradually before you start using it again. The longer it stayed below normal operation temperatures, the more gradual the recovery should be. Else, you risk to shock your device. Using your iPhone intensively leads to warming up. If this comes sudden, before your phone recovers from its exposure to below freezing temperatures, dangerous condensation can occur. That’s tiny water droplets developing inside the housing of your gadget, because of the sudden temperature difference. Prevention is best and this is why I recommend you these iPhone hibernation tips!

iPhone High Temperature Alert

However, you should avoid exposing your device to direct sunshine. The iPhone’s fabric attracts and stores the heat pretty efficient. Your device can experience overheating even without being exposed to outside heatwave. If you abuse multitasking and overload it, it might warm up over the limit. A cool down break is recommended in this case. iPhones can sometimes overheat when charging, but as long as no alert is displayed on your device’s screen, things should be fine.

The emergency call function, is the only feature available on your iOS device, when the extreme temperature warning is displayed. But, if your battery levels where already low, your iPhone could shut down prematurely. In my case, my battery level was 35% when I forgot it outside. One hour later the frostbite warning was on and the battery indicator showed 1%. My device refused to turn on until I left it 30 minutes indoors. When it finally powered back up, it was displaying a 22% battery level. Will never misuse it again! ;)
