The Apple system that prevents this from happening
It is likely that you have ever noticed that, when you grab your iPhone, it is hotter than usual. This generally occurs when the device is running heavy processes or several of them at the same time. Indexing data after restoring, processing a high-resolution photo, graphics-demanding games… So that’s completely normal.
Based on this, you may wonder if with a high demand for several minutes and hours the battery or something similar can catch fire. And no. Apple implements a protection system for the iPhone against overheating that prevents the device from reaching temperatures that could endanger the terminal itself or yourself.
When iOS detects that the iPhone is reaching these high temperatures, it closes all open processes and shuts down, simply displaying a message warning that the device will not be functional again until the temperature is reduced. At this point it is impossible to turn it on, so the risk of greater evils occurring is practically nil.
The use you should do to avoid problems
Perhaps on some occasion you have read or seen a video in which a burned iPhone is shown. And although we do not want to deny such a fact, the truth is that it has never become generalized nor has sufficient evidence been provided to indicate that those few users have not exposed their iPhone to non-recommended conditions.
And, if you follow a series of simple guidelines, nothing like this should ever happen. Guidelines that are also dictated on many occasions by common sense. At the point where the iPhone cannot be turned on due to high temperatures as we discussed earlier, you should not expose it directly to sunlight or high temperatures that do not favor its cooling. Although it is not advisable that you take it to excessively low temperatures suddenly. And no, a fridge either, since the contrast could also be dangerous.
It is also recommended that when the device is in this state do not put it to load, since energy would be entering it that would only favor it to continue heating or, failing that, that the temperature it currently has does not drop. It is also recommended remove the cover, if it has, so that it can favor the regulation of its temperature.
So, following these tips and thanks to that native protection system, we can affirm that there is no risk of an iPhone battery exploding. And to be honest, in the rest of the brands it seems also difficult to find these problems if recommendations such as the ones we have discussed are followed.
