Leaving the iPhone charging all night does not cause any damage, do not believe the hoaxes

Today we read in a blog within the network of the sports newspaper As called Betech that it is not a good idea to charge a smartphone during the night , which is when many of us have the habit of charging our iPhone ... we put it to charge before going to sleep and in the morning we have it at 100% capacity. In this article they link this study from The Battery University where they point out many of the factors that cause a battery to degrade prematurely, such as charging them at a higher voltage to accelerate the charge or temperature to which they are exposed when do they work.

Well, to make it clear from the beginning, there is no problem in leaving the iPhone charging throughout the night , because in fact, it does not charge during the whole nighteven if it is connected to your Lightning charging cable or if it is in a wireless charging base. The reason is that, as they also say in Betech, a system for charging the battery when approaching 100% capacity. In fact, loading from about two-thirds of the total load is done much more slowly precisely to degrade the battery less. It happens in smartphones, tablets, and even in electric cars, whose fast charge allows to reach 80% capacity in a few minutes but then requires much more time to reach 100%. Although the degradation of batteries in electric cars is not as serious as in smartphones due mainly to their size, all these systems allow to extend the useful life of any device that stores electrical energy.

In that article by Betech, it is said that although charging for, the temperature of the smartphone remains high. We can confirm that if the load is automatically stopped, the temperature does not increase ... in fact, it is substantially reduced. All we catch the iPhone rather chilly morning, even after having left overnight charging, for that reason. Unless there is no other source of heat near the iPhone, such as a lamp whose incandescent filament bulb is next to it, or heating, the iPhone will not heat up in the least and the battery, once charged, will maintain its load because the machine will be feeding directly from the charging cable.

If that not to connect the iPhone to its charging cable all night was true, a long time ago Apple would have indicated that to its users, or would have devised a system so that it was not a problem. This system has been implemented for a long time in laptops, tablets or smartphones, not only Apple, but virtually any brand. The chips in charge of controlling the charging systems nowadays are very sophisticated and advanced, and something like the heating of the system when the battery is charging, is already very controlled ... an unexpected increase, can result in the load to stop perform, as a security measure. Of course, when the battery charge is finished, they also monitor all temperatures and all this is recorded in a file that can then be checked in any Apple Store, with the program that evaluates from its intranet how it has been downloaded and charging the battery in recent days to determine if there are irregularities in these processes. If there are, it is suggested to change the battery, of course free of charge if the iPhone is under warranty, and if it is not,for € 29 throughout the year 2018 .
