Although it is not a frequent occurrence, excessive overheating of a iPhone It can happen and should not be underestimated, especially to avoid consequences in the correct functioning of the electronic device: knowing the causes can help to remedy the problem.
But what could be the reasons? The first element that overheats is the drumsan event that occurs especially when the screen and especially the phone’s processor, the component that takes care of data processing, are used for a long time and intensively. Antennas also overheat easily, especially when you are in areas with poor reception and the search for signal reception is continuous: this happens, for example, even during car trips. As anticipated, the screen can also to warm up abnormally, which occurs when the iPhone is used continuously without ever turning off the display. To make the situation more complicated, especially during the summer season, direct exposure to sunlight on the beach.
In case the temperature of the device is excessive, that is, above 35 degrees centigrade (since the range is 0-35°C), iOS warns the user with an explicit message: “iPhone must cool down before being used“. The functions of the cell phone are then blocked preventively to avoid repercussions on the electronic device, with the exception of emergency calls. If the problem is exposure to direct sunlight, there is no need to worry and a very simple remedy can be found by sheltering the cell phone.
The situation may be more serious if the overheating is due to heavy use, but even in this case you can act autonomously: this happens when you use heavy games or apps, when the GPS is active or the applications remain running in the background also performing updates automatically. By disabling these functions you can prevent overloading the iPhone.
If, despite implementing these remedies, the temperature remains excessive and the iOS slows down significantly, it is still possible to implement some countermeasures. Apple’s first recommendation is to update the operating system and all apps used on the phone: outdated versions can hide problems and cause abnormal heating.
This sometimes also happens when the memory of the electronic device is too full: in this case you can free up space to do a further test, deleting videos, photos or “heavy” files.
The last hope is to make a backup and proceed with the restore, without installing any app as a precaution: if the heating persists it is advisable to contact support.
