IPhone charger that heats up, what to do?

Do you notice that your iPhone charger gives off heat when you plug it in? This phenomenon is not surprising as long as the heat emitted is not too high. However, when the temperature rises too sharply more than usual or other side effects appear on your iPhone, the problem may be more serious and require intervention. In this case we will see what can you do when your iPhone charger heats up.

First of all, we will see qThese are the causes that can cause your iPhone charger to heat up. Then we will see the solutions that exist to avoid the abnormal overheating of your iPhone charger.

Why does the iPhone charger get hot?

When your iPhone charger heats up, cause may be natural and not reveal any specific anomaly but it can also come from some malfunctions. So, learn to recognize the origin of the heat to better resolve it.

Natural causes for an iPhone charger to heat up

Is it normal for my iPhone's charger to heat up? Is there a risk to the charger, the smartphone or my health when the iPhone charger overheats? How normal is it to see the temperature of your charger increase? Here are all the questions that may arise when an iPhone charger heats up. However, rest assured up to a certain point, it is quite normal for this phenomenon to occur.

Indeed, during charging, the charger supplies the iPhone with direct current. When converting alternating current to direct current, energy is consumed. And this energy is released in the form of heat. So, you will understand, it is It is quite normal for the iPhone charger to heat up slightly during charging. Note, moreover, that Apple chargers tend to heat up slightly more than Android chargers. So, if you have just made the transition from one smartphone to another, you may be surprised at first.

Note: If you are using a fast charging apple charger, the heat output may also increase. Indeed, this is due to the fact that the current at the terminals is higher. 

So there is nothing to worry about seeing a slight increase in the heat of your iPhone charger until a certain point. Indeed, it can happen that it heats up much more than usual and that this is therefore a sign of overheating. In this case, this problem can be caused by different factors.

Causes of a malfunction resulting in overheating

When the your iPhone charger gets too hot, we say he overheated. The signs of this overheating can be various: a charging stop, a burning AC adapter, too slow charging, a burning smell etc. Of course, you can also notice it in comparison to your old chargers or if it suddenly gets hotter than usual.

Here is Factors That Can Cause iPhone Charger Overheating :

  • A ambient temperature too high and a room that is not sufficiently ventilated.
  • A faulty electrical installation with excessive voltage variations or peaks.
  • The use of a damaged iphone charger.
  • The use of a counterfeit charger, of poor quality and therefore not Apple certified.

When the temperature of iPhone charger becomes abnormally high, it will therefore be necessary correct the origin of the problem because this can lead to more or less serious consequences such as a failure of the load elements (capacitors, transistors), an electric shock or a total failure of the device. Then proceed to the troubleshooting steps below.

What to do to avoid overheating an iPhone charger?

We have just seen it, when the charger of your iPhone overheating, many factors may be at the origin. Then follow the troubleshooting steps in sequence to try to find the origin of the problem and thus solve it effectively.

why iphone charger overheating

Check the charging environment and electrical installation

At first, when you have a iPhone charger that heats too excessively, you will need to check that environment and electrical installation are conducive to its proper loading. To do this, carry out the following checks and operations:

 Make sure you charge your iPhone in an ideal environment. The place should be ventilated, dry and not too hot. Avoid direct exposure of the Apple charger to direct sunlight. Also be careful not to put it near a heat source (radiator, oven, hob, etc.). Finally, avoid covering it when it is charging.

How to conserve iPhone charger and battery for longer? Since iPhone lithium-ion batteries are temperature sensitive, avoid exposing your iPhone to temperatures below -10 ° C and above + 40 ° C. The rule applies in particular when recharging the battery. Also note that a charge level that is neither too low nor too high will increase battery life. So try to maintain a charge level between 20% and 80%. 

• Try charging your iPhone at a different wall outlet to verify that the AC outlet you are currently using is not having voltage problems.

• Check your iPhone charger for damage (stripped, folded, damaged etc). Indeed, its internal conductors can then trigger a short circuit. The charger still tries to maintain charging with the voltage needed to charge. As a result, it can cause the transformer to overheat.

• If you are using a power strip or an extension cord, remove them. Indeed, this equipment can cause electrical interference if other devices are connected to it. In addition, the more devices connected to it, the more voltage variations there are that can cause the iPhone charger to heat up. Then plug the AC adapter directly into a power outlet.

Note: To prevent premature iPhone charger failure, unplug your charger from the electrical outlet when you have finished charging the device. 

Use a quality iPhone charger to avoid overheating

When you own a iPhone charger overheating and that you have complied with the environmental and connection prerequisites, you must then pay attention to the quality of the charger.

For choose a quality iPhone charger, see to avoid fakes and that it is Apple compatible or certified.

Avoid fakes

Are you using a genuine Apple charger? Indeed, if your iPhone charger gets too hot, check that this one not be a counterfeit. There are several reasons why you should avoid them:

1 / Counterfeit or “generic” chargers are of lower quality in terms of their design and production than genuine chargers. In fact, in addition to the components used which risk being damaged much more quickly, their assemblies often leave something to be desired. Thus, they can cause various malfunctions such as overheating of the charger.

2 / The authentic chargers supplied in iPhone boxes, on the Appel site or in approved stores, all have a security made of sensors placed in them to stop the charge and prevent overheating.

3 / Counterfeit chargers of unknown or uncertified brands sometimes offer products that do not comply with the indications on the box.

Note: Also be careful if you have had the battery replaced so that it is genuine. 

How to choose a compatible or certified charger?

For choose a compatible and quality iPhone charger that does not heat up abnormally, first check the voltage, polarity and nominal charger current. The original direct current must be the same. For example, an original charger intended to provide a charging current of 3 amps for 12 volts should not be replaced with a charger which provides a current of 2 amps for 12 volts. Note that in any case, the charging current should not be lower than the original one because a under load capacity is the most common cause of overheating of the device. Conversely, higher currents will reduce battery life.

Un quality charger will also most certainly have a higher price because it integrates technologies and safety standards requiring a higher manufacturing cost. For example, they incorporate a charge management technology capable of handling the intensity of the current according to the internal temperature of the charger and the level of the battery. Counterfeits do not have such technology. They therefore do not have overload protection and therefore do not stop charging even when it has reached 100%. As a result, it will both cause overheating but also damage your equipment.

For be sure to choose a quality iPhone charger that is compatible with your smartphone, we advise you to opt for genuine Apple adapters and cables on sale on their website or in the Apple Store. You can also find it in stores and online sites. But once again be careful that they are reselling products Apple certified (and which therefore bear the MFI “Made for IPhone” badge). For Lightning, USB or USB-C cables, you can use compatible ones, but also be careful that they comply with national regulations as well as applicable international and regional safety standards.

Note: Also check the compatibility of the power adapter and the USB or USB-C cable. This is because a USB cable does not provide the same power as a USB-C cable. Thus, if you use an adapter of more than 12W, you should preferably use a USB-C cable. 

Buy a new iPhone charger

If you notice that your charger is not suitable as we have just seen or if during the uses of your iPhone charger (original or certified), you notice that it loses in loading efficiency and heats up more, the problem is most likely a short circuit or an electrical fault in the AC adapter or Lightning cable.

In this case, you will need to test whether the fault comes from cable or adapter, then you buy a new one. In the vast majority of cases, this will be the adapter. Once again, make sure that it meets the conditions seen previously.
