If you’re noticing that each time your lightning cable charger is plugged into your iPhone for a while, it starts to get hot to touch. Usually, it’s the iPhone charge cube that gets hot – this is the plug plugged into the socket. Sometimes it the cable itself that gets hot alongside the connector itself.

You should know that it’s not normal for your cable to get hot or even the cube. If you’re in a hot climate, then your cable might be ever so slightly warm to touch but if you’re not in an extremely hot climate, then you shouldn’t be experiencing a hot cable. This problem would have happened to most iPhone and iPad users while using their iOS devices.

Why Is My iPhone Charger Hot?

Your iPhone cable is overheating because of the actual USB itself.

There can be all sorts of problems wrong with the internal electronics of the lighting cable but since your cable is covered by an insulator, you can’t open it up to see if there’s anything wrong with the cable.

Your iPhone’s lightning cable may be fake which is another reason why it’s going to start heating up when you charge your iPhone or iPad. This problem can easily be fixed so you shouldn’t have anything to worry about.

The last reason your charger is getting hot when you charge your device is water damage. If the cable of your iPhone has come into contact with a lot of water, this can cause it to get hot when you charge your device.

If you notice that your charger and cable get very hot when you’re charging your iPhone, it’s a sign that you should stop using that cable and get it replaced. If you continue to use that cable, it could warrant some serious problems down the line such as a sparking socket or the cable melting which isn’t something you want to happen.

Why Does my Cable Start Breaking?

There are plenty of factors that can be involved when your charger starts to go bad. My iPhone cable went bad and I wasn’t aware of the reason. It’s not necessarily your fault if your cable goes bad because it can happen because of a reason you’re not aware of.

You’ll usually notice that the white plastic covering the wires start to push to one side. The reason this happens is unknown and it’ll start to happen when you’ve had your cable for quite some time.

The best way to stop this from happening is to stop bending you cable frequently or stop curling up your charger.

How To Stop Charger From Getting Hot

There are a few things that you can do to make sure that your charge no longer overheats. Of course, the safer bet would be to make sure that you replace the charger because any charger or cable that’s getting hot is faulty.

Plug it Into a Single Socket Rather Than an Extention

If your charger is plugged into a socket and you notice that it’s getting hot, the first thing to do would be to plug it into a single socket and check if it overheats when it’s plugged into there. Sometimes when there are other things plugged into an extension, it could cause your cube to overheat so you want to plug it into a single socket to make sure that your charger is the only one there.

Check If the Charger is MFI Certified

The main reason your charger is going to overheat is that your cable isn’t real. Fake iPhone chargers can have all sorts of problems and one of them can be overheating.

To check if the cable is MFI certified, you need to look at where you got the charger from and you need to look at the packaging it came in. If you got your cable from an unreliable source, there’s a high chance that this is going to be fake.

If you look at the packaging of the charger, you should see a white and black logo that says ‘Made for Apple’ or something similar. If you can’t see this anywhere on the packaging, the charger is most likely fake and this may be the reason it overheats.

MFI is a certification given to lightning cable manufactures and it basically means that the charger meets Apple standards. Apple meets the same standards when making their cables so, they give the MFi certification to other manufacturers that follow the same procedure.

Can an Overheating Cable and Charger Cause Damage to my iPhone?

It’s unlikely that an overheating charger can cause damage to your iPhone or iPad. Your lightning port can handle pretty much any issue even if it’s the cable heating up. The only thing that can really harm your iPhone via the port is water damage and major physical damage.

There’s only really one way that the cable can harm your iPhone, and this is a short circuit. If there’s a short circuit in your cable, this can cause damage to your iPhone and the lightning port. A short circuit happens when two or wires that are not supposed to come in contact with each other touch.

A short circuit can result in a very high current flowing through the circuit and therefore, damage your iPhone or iPad.

Get a New iPhone/iPad Cable

The best way to fix this issue is to simply get a new iPhone cable. This most likely going to stop the cable from overheating. If your iOS device has experienced major physical damage or water damage, then you may still experience problems even if you buy a new cable.
