Why is My iPhone Overheating While Charging?

It’s not normal for your iPhone to get hot while charging. Overheated phones can become damaged, and the battery can lose its capacity. There are several reasons why an iPhone might overheat while charging.

Faulty Charger

A faulty charger is a common reason that iPhones overheat. If a charger does not work properly, it could send the wrong signals to your phone and cause it to overheat. 

Using an Apple-certified charger with your device is important, as non-certified chargers may be of poor quality and cause overheating.

External Factors

External factors such as direct sunlight or high temperatures can cause your phone to overheat while charging. Make sure you’re not leaving your phone in direct sunlight or other hot environments when charging it.

Faulty Adapter

The adapter to connect the charger to the wall outlet may need to be fixed or low quality. This can cause your phone to overheat while charging, so make sure you’re using an adapter compatible with your device and in good condition. You can order for one from amazon.

Internal Damage

External factors such as high temperatures or direct sunlight can cause your phone to overheat while charging. Keep it away from direct sunlight and other heat sources when charging it up. 

Additionally, avoid using cases that block air vents on the back of your device, as this will trap heat inside and make it more likely to overheat.

Broken Port

If the port on your phone is damaged or broken, this can also lead to overheating when charging. If you notice any signs of damage in the port, such as bent pins or debris, take your phone in for repair as soon as possible.

How to Fix iPhone Overheating While Charging

You can try a few solutions if your iPhone is overheating while charging. Here are some tips to help:

At this point, it is important to unplug your device immediately when it overheats. This will prevent further damage and allow the phone to cool down before you can troubleshoot the issue.

2. Cool Your iPhone

Cooling down the phone can help to reduce the temperature. This can later reduce the chances of your phone being damaged. 

While waiting for it to cool down, you can use the following methods to speed up the process:

2. Check Your Cables: Your charging cable may cause an overheating problem. Check to make sure that it is working properly and not damaged in any way.

 If you notice some bulging, fraying or blackened cables, it indicates that you should replace your cable. Switch to a certified Apple charger for better results if you use a third-party charge.

3. External Factors: Is your phone exposed to direct sunlight? Or is it in a very hot place like your car’s dashboard? Such external factors can cause your phone to overheat. If this is the case, move your device to a cooler place. 

4. Minimize CPU Activities: Your phone may be overheating due to the heavy processing activities that it is doing. To reduce the temperature, try to minimize your CPU activities. Close all the running apps, and turn off the Bluetooth and Wi-Fi connections.
