Reasons Why Your Phone and the Wireless Charger Get Hot
Not lining up correctly. The key for wireless charging is the coils in the charger and the phone. If the coil in your phone does not align with the one in the wireless charger, more magnetic energy will be consumed and more heat is produced.

Such objects will reduce efficiency and cause overheating during wireless charging.
Wrong wall adapters or cables. For wireless charging, you should use the original adapters and cables from the charger or from your phone. If you use the wrong or damaged one, it would heat up your phone. For example, a damaged USB cable will cause the lower part of the phone overheats.
Using the phone a lot during charging. Gaming for long periods of time, watching YouTube or movies, using power-consuming app such as Google Map, or doing video calls during wireless charging will make the phone hot and even cause overheating that will shut down the phone.
Environmental factors. If you charge your phone on a wireless charger in a hot place, such as outside in the sun or in your car in a hot day, it can cause the phone getting hot easily.
App or software issues. If an app has conflicts or bugs, it may cause your phone to overheat by overusing the phone's processor. Software does the same.
