That an iPhone gets hot is not necessarily a bad thing, since there are situations in which it is even normal. However, if you have been noticing that during charging it heats up excessively or even turns off due to temperature issues, you should be concerned. And it is that this last case is not at all common in a process as standard as recharging the battery.
The main reasons for the problem
One of the reasons why the iPhone gets unduly hot while charging is due to the cable and/or power adapter being used. They may be defective, either from the factory or due to use, but it may also be due to not being MFI chargers (Made For iPhone), which is the standard offered by Apple to manufacturers of this type of accessory that meet its efficiency regulations.
On the other hand, use fast charging It can also be a reason for heating. And it is not that iPhones are precisely characterized by supporting very fast charging, but the most recent models support up to 20 W of power and on these occasions they tend to heat up more than necessary, although it is not very normal for this to happen either.
It is also possible that if you are using a wireless charging pad notice a greater heating, being completely normal. Although in the end the cause that causes a higher temperature is usually always that of use while chargingespecially if the use is intensive with applications and/or games that require high consumption.
Similarly, the room temperature Where you find yourself can be decisive. It is always recommended that the iPhone be in slightly humid environments and with a temperature below 25ºC and without the sun shining directly on it. And if it is charging on top, all the more reason, since in itself it is a process that raises the internal temperature.
Therefore, and as a summary of these points, you should always keep this in mind to prevent the temperature from rising during charging:
- The cable and adapter you use are in good condition.
- Don’t abuse fast charging.
- Use chargers that are MFi, although they are not original Apple, there are many that have this standard and guarantee a good charge.
- Do not use the device while it is charging and even less so to play games or carry out similar processes.
- The temperature of the room is adequate.
What if the battery is defective?
If you make sure to comply with the advice given above and despite this you still consider that the temperature of the iPhone rises too high, you will have no choice but to go to the technical support. And yes, we know that it can be tedious and you can probably not give it much importance, but it can be crucial.
Both liquids and high temperatures are enemy agents of electronic devices and could end up leading to major failures. For this reason, even if it is only as a precaution, it is best to have it checked by a specialist. It may even be due to a factory fault and you do not have to pay anything for the repair, since these are covered by the iPhone warranty.
