How Wireless Charging Works On Android Smartphones And How To Get It On Your Phone

First off when the word "Wireless Charging" comes to your mind I'm sure you had the same thoughts I had at first about it. -"Electric currents flying in the air unseen and possibly may shock someone if there's an issue with the charger".

I know that's a pretty dumb theory but don't judge me , your own initial thoughts about it could be worse. Nevertheless, In this post I'll be explaining how wireless charging works and the fun part is that you can get on pretty much any Android device but I'll only tell you how to do that at the end of the post. So how does wireless charging actually work?

If you didn't skip physics class you should get a vivid imagination of how it works from this explanation. Wireless chargers use magnetic induction. They use magnetism to transmit energy. First, you place a smartphone on the wireless charger. The current coming from the wall power outlet moves through the wire in the wireless charger, creating a magnetic field. The magnetic field creates a current in the coil inside the device sitting on the wireless charger. This magnetic energy is converted to electrical energy, which is used to charge the battery.

 Devices must have the appropriate hardware in them to support wireless charging—a device without the necessary coil can’t charge wirelessly.
I really prefer the Qi (pronounced Chee) standard of wireless charging as it supports magnetic resonance which means the device can be up to 45mm away from the wireless charger’s surface rather than touching it directly.

 Although it is not as efficient as magnetic induction, however there are some advantages—for example, you can place a wireless charger under a table surface and you can place a device on the table to charge it. It also allows you to place multiple devices on a single charging pad, and have all of them charge at once.
Although I can't really understand why most Android OEMs have been moving away from wireless charging and Samsung just kept it on their high end smartphones so I'm guessing it's to reduce production costs. Here are a couple of devices that support wireless charging

Apple iPhone 8, iPhone 8 Plus, and iPhone X
Samsung Galaxy Note 8 , Galaxy Note 9 and Galaxy Note 5
Samsung Galaxy S8, S9, S9+,S8+, S8 Active, S7, S7 Edge, S7 Active
LG G6 (US and Canada versions only) and LG V30
Motorola Moto Z, Moto Z Play, Moto Z2 Force

Now if you aren't using using any of these devices, here is how you can get wireless charging working on your phone. There are a couple of methods to achieve this but the easiest way is by using a s tick-on wireless charging adapter.

Stick-on adapters offer a more universal solution. If your phone doesn’t have the circular RF induction coil that’s the core of any wireless charging device, just add one on. It’s a flexible solution that needs only a few basic models to cover almost any phone.\
The advantage to stick-on adapters is availability. All you have to do is just place one of these external pads up to your phone’s charging port (USB-C, Apple Lightning, or MicroUSB), stick it on the back, and you’re good to go. They’re also much cheaper than wireless charging cases, and they’re slim enough to fit underneath the plastic of a standard, non-charging phone case.
