Some basics are important to help understand your phone overheating during charging. If you only want the reasons and solutions, jump to the 2nd and 3rd parts.

What’s Overheating on Wireless Charger? Overheating VS Warm

What’s phone overheating during charging? Overheating VS warm, what’s the difference?

Generally, a phone’s internal temperature can reach 37-43 degrees Celsius (98.6-109.4 degrees Fahrenheit), and this is considered normal.

You can install a temperature detection app on your phone. It should give you a temperature report so you will know if your phone is getting too hot, which can be consider to be overheating.

The most direct physical way is that if the phone is getting too hot to touch or if the temperature is physically uncomfortable, it’s overheating.

Most phones can sense the temperature and will stop charging automatically to prevent further heating to avoid damage. That’s why you may notice your iPhone stops charging at 80%.

Some phone even shut down automatically to avoid damage and more overheating.

A high quality wireless charger from a top brand can prevent overheating. It has built-in smart system to control heating up. But many in the market won’t. So it’s very important to choose a good wireless charger (we’ve covered this in the last part)

However, if overheating happens a lot, that will reduces the phone battery wear and tear; and if the phone is too hot, that will cause damage to the phone software and firmware.

Why Your Phone Gets Hot During Charging on a Qi Wireless Charger

Many inappropriate operations will cause your iPhone or Android smartphone heating up during wireless charging, and the wireless charger gets hot.

Below are the most common reasons for your phone overheating on a Qi wireless charger.

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.

Foreign materials. The ideal status for a phone to be wirelessly charged is to just place the phone on the center of the charger, no objects between the phone and the charger, especially metal objects, magnets and magnetic strip cards. 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.
