3 things you need to know about Wireless Charging

 In Informative

Wireless charging is a convenient way to charge your device by removing the need for charging cables that fit your device. Below are 3 things you should know about wireless charging.

1. Qi Wireless Charging

The standard for wireless charging is called Qi. Qi (pronounced “chi”) technology is used in brands from iPhone to Samsung to Google etc., so the same wireless charger can be used for any wireless compatible device, similar to WiFi and Bluetooth technology.

A device must be Qi-compatible to be able to use wireless charging technology.

Wireless charging works by transferring energy via electromagnetic induction from the charger to a receiver. Using an induction coil, an electromagnetic field is created, which the receiver coil converts back into electricity and delivers power to the battery.

Wireless charging is very simple, but there are a few things that could interfere with delivering a successful charge to your device.

The most common issue is that the phone’s receiver does not line up with the charging coils. Even if your phone is just a little off-center, your device may not charge.

This is a simple fix – keep your eye on your phone and if you do not see the charging message initiate, reposition your phone until it works. The images below demonstrate where the charging coils sit inside a iPhone X and Samsung Galaxy S9. These coils should be aligned with the wireless charger that you are trying to use.

Use the location of the blue rings in the images to see where the wireless charging coils and receivers are located in different devices.

Another common issue is the thickness of the case on the device. Most wireless chargers can deliver power through 40mm (1.5in) of material. If your device is not wirelessly charging, your case may be too thick. Simply remove the case wile charging.

Do you have a metal receiver or magnet in your case? Some mounts or cases add metal components to allow them to function. This will also interfere with the wireless charging connection.


Wireless charging is slower than conventional charging using a cable. Each device can accept a different amount of power that influences the charging times for the device. Wireless charging has a lot of pros and cons in regards to its convenience and compatibility, but its charging speed falls to be its biggest downside to the technology.
