Why iPhone gets overheated while wireless charging

You didn’t mention the overheat message before. That changes things.

You need to determine why your iPhone is overheating. The usual reason is an app that is consuming too much power. Go to Settings -> Battery and look at the Activity graph. It may show that your iPhone has constant high activity. The Battery Usage by App list will show which apps are consuming the most CPU or battery resources.

If your iPhone has detected a problem with your battery, that same screen will tell you about it.

Note that you are not talking to Apple in these forums. Commenting on your perception of product quality will get you nowhere, and will cause knowledgeable people to skip over your post rather than providing valuable feedback.

Because it is working exactly as expected.

If you are using a thick case around your iPhone, it may cause more heat and prevent heat from dissipating. Even if it is certified for wireless charging.

Wireless charging is inherently less efficient and generates more heat than wired charging. Particularly when charging for a long time.

Is continuous heat while charging iPhone batteries detrîmental to battery life time?

I have the same problem with an iPhone 11 it’s extremely frustrating and yet another indicator of apples arrogant attitude toward their customers ( and all else )

Does it hurt the iPhone when charging on a wireless charger and the phone gets hot
