In fact, nothing terrible will happen to the smartphone (provided there is no mechanical damage to the battery) – from overheating it will not let out its last breath in the form of a bluish plume of smoke, as it could have happened, for example, with an old Soviet TV.
According to Apple’s data, the iPhone must be operated in temperatures between 0 ° C and 35 ° C. When this range is lowered or raised, the smartphone can change its behavior in order to regulate the temperature. For example, using the device in a low temperature environment results in to the temporary faster battery discharge, whereas at very high temperatures the battery life may be reduced irreversibly…
At the same time, the temperature range for storing iPhone when turned off is -20 to 45 ° C.
What happens to an iPhone when it gets too hot
When reaching a really high critical temperature:
– the operating system will stop or slow down the charging process, including wirelessly;
– the performance of the device will decrease when using programs or functions with augmented reality or with high graphics requirements;
– the smartphone display dims or turns off;
– cellular communication modules will switch to lower power consumption (the quality of communication may deteriorate);
– flash and cameras will be disabled;
– a warning may appear on the iPhone screen Temperature: iPhone needs cooling before using…
So, let’s take a look at the most likely causes of iPhone overheating and how to fix them.

Resource-intensive applications (games)
This is the most obvious and common prerequisite for raising the operating temperature of an iPhone. Naturally, the design of the compact device does not provide for a cooling system, and at high loads the processor of the device works in a dense aluminum-glass box, which by itself leads to overheating. Especially when using augmented reality or graphics-intensive applications. IPhone will get even hotter if it is connected to the mains or actively using the Internet connection while playing.
In this case, you can cool the gadget in the most banal way – by eliminating the causes of heating. That is, you should close a resource-intensive application, disconnect the charger, or stop transferring data over the Internet.

Long conversation on the phone or downloading content from the Internet, as well as Tethering
Active operation of wireless modules during a long telephone conversation or transferring large amounts of data (downloading a movie, listening to or downloading music via the Internet, working in Modem Mode) can also cause an increased temperature of the device, but immediately after these processes are completed, it will drop to a normal value.

Dense “insulated” cover
Some accessory makers offer special cases for iPhone that prevent the smartphone from overcooling in freezing weather. Of course, the opposite effect also takes place – such “clothes” can lead to a slight, but constant overheating of the iPhone.

It is a very rare, almost mythological case when the iPhone overheats due to the fault of Apple developers who made mistakes in the iOS code. Even in beta versions of the apple operating system, this is extremely rare, however, to be faithful, especially vigilant users can be advised to perform a hard reboot or, in extreme cases, flashing the iPhone.
