Wireless charging is a new feature that comes along with iPhone 8, 8 Plus, and X. When I ordered my 8 Plus I got a wireless charger, too because why not? There seems to be many benefits to wireless charging rather than wired charging. It's been a few months since I started using it and I thought I would note my experience.
A few years ago, Phil Schiller, Apple's VP of marketing made a comment about wireless charging. Phil stated that wireless charging didn’t make sense because it still involves a cord. Of course it involves a cord. However, it's a nice convenience. It may not seem like it, but the ability to just set your phone down and have it charge is really nice. No need to search for the lightning cable which slid off the table sometime between you disconnecting your phone and you coming back home anymore. No need to stand it up on a dock either. No need to sacrifice listening to music while charging. Just simple wireless charging occurring.
Some of the wireless chargers available are ugly. There are a few ok looking ones. I look forward to when Native Union debuts one. They seem to be the only company to create Apple accessories with a true standard of creating beautiful products. What's superior to stand alone charging pads are integrated ones, though. Ikea has a couple of nightstands and lamps featuring built in wireless charging pads. I'm sure more will become available in the future.
Doesn't Replace A Standard Dock
The need for a dock is still necessary at times. Whether you want to have your screen at your desk and upright for easy viewing. Or maybe you want to FaceTime while all working on your computer. These can't be achieved with a dock because the phone has to be flat on its back.
If you are someone who currently uses a dock or a stand, you will want to keep it around for the occasions where you need them. Besides that, I highly recommend a wireless charger. It seems frivolous, but it is actually convenient enough to be worth the purchase.
