Qi is the most popular wireless charging standard amongst the smartphones.

How Does Wireless Charging Work?
Wireless charging works by transferring energy from charger to the receiver in the back of the phone via electromagnetic induction. The charger uses an induction coil to create an alternating electromagnetic field, which the receiver coil in the phone converts back into electricity to be fed into the battery. They typically have to be in close proximity to each other and correctly aligned over the top of each other, although a set orientation is normally not necessary.

Are there any downsides of wireless charging?
The biggest downside is that wireless charging cannot be performed through metal with current technology. That means most wirelessly charging smartphones have either plastic or glass backs, the latter of which makes them more fragile.
