Back in the 19th century, engineering extraordinaire Nikola Tesla demonstrated the phenomenon of electricity to be transmitted through air, generating a magnetic field; the idea for wireless charging was born.
While wireless charging technology has been around for years, its recent introduction into the world of Apple has shaken things up and changed the way iPhone users experienced their smartphones. Introducing this type of charging in the iPhone 8, 8 Plus, and iPhone X, Apple unveiled its very own charging plate known as the AirPower.
The Qi-enabled wireless charging power plate runs at 7.5 watts to juice up your iPhone. It’s not only a cool new feature, but one that many iPhone users appreciated. Here is a brief guide on how wireless charging works for the iPhone.
What is Wireless Charging?
Just like the popular “hoverboards,” the moniker “wireless charging” can be a bit misleading. Like hoverboards don’t actually “hover” above ground, wireless charging isn’t like cell service or Wi-Fi. You can’t just wirelessly charge your phone while sitting feet away from the charging point. Most inductive charging technology makes use of magnetic coils in order to transfer energy. And for your iPhone to be able to charge properly, it needs to be within close distance of the coils’ magnetic field.
Also, unlike the name, wireless charging still needs wires to be able to charge your device. You will need to connect a wire from the charging mat to the power source. So you’ll still have to carry around a power cord. The point of being “wireless” is that you don’t have to connect the wire to the actual device.
Inductive wireless charging is pretty convenient. You don’t have to connect it to a wire so there’s no physical restraint. Also, we put our phones down a lot, so why not just grab a fast charge while you’re at it. You can put your iPhone down on the charging pad to charge it conveniently.
There is also the security factor coming into play. Connecting your iPhone to just any unknown charging cable can seem a bit unsafe. It can attract all sorts of malware and corrupt your iPhone. But placing it on a charging mat will need no physical connection and is pretty safe.
The drawbacks aren’t glaringly bad. Just like with a cord, using your iPhone functionally can become a bit harder. But with a charging cord, you can still move your iPhone around in the air. With wireless charging, the iPhone has to be placed flush against the charging plate for it to work. So you will have to swipe and tap on your phone against the table.
