Wireless charging of your phone means you don't have to mess with cables when you want to charge it. Pretty much all new, slightly more expensive mobile phones support wireless charging (Qi). Here's how it works.
Have you seen the technical abbreviation Qi and wondered what it stands for? It's a marking that has become increasingly popular in recent years, with basically all new phones featuring it. Qi is the technology that charges devices wirelessly and means energy flow in Chinese.
No more messing around with cables, all you have to do to charge your device via a wireless charger is place it on the charging pad.
Wireless charging is usually done via a pad connected to a cable, which is plugged into the wall. Your phone, or any other Qi-compatible device, is placed on the pad and it starts charging automatically.
You don't usually get a wireless charger when you buy a phone, so you may miss out on the fact that it supports wireless charging. You can easily check if your phone supports wireless charging by googling. Since many devices such as AirPods and many smartwatches support wireless charging, you can use the same charger for all these devices. Convenient, right? Only having to keep track of one charger.
How does it work?
The device placed on the pad sends information that it's ready to receive power, as well as how much energy it needs. An alternating current is then sent through a copper coil to create a magnetic field that affects the corresponding coil in the phone. This in turn generates current which then charges the battery.
