Wireless Charging – The future, again?

iPhone X

2017 has been a year of many new smartphone trends with dual cameras, near bezel-less screens etc. With these in mind, Apple released it’s best ever flagship smartphone the iPhone 8 and iPhone X the latter featuring a gorgeous bezel-less screen with the infamous notch reintroducing a feature that many have previously overlooked, Qi wireless charging. Will this inclusion set the mark for more and more smartphones including the technology in the future or will the failures of the past remain most dominant?

How does the wireless charging work?

Qi charging is wireless however, it uses a wire to connect the base station to a power outlet, connecting the wireless charger to a source of electricity. We can then place the smartphone on to the base station without having to plug anything into the phone. Not every phone supports this charging method so a test signal is sent from the charger to the smartphone which responds to the charger confirming it received the ping and is supported to charge.

The base station then generates an electromagnetic field through its transmitter coil that induces an electric current to the receiver’s coil within the smartphone. The transmitter then adapts output to reach the devices full power level before entering standby mode once it is complete.

Qi charging has always had benefits over regular charging, no cables mean no tangling and increased longevity since they do not suffer from fraying like regular charging cables.

Another benefit that has come to light very recently is that since any Qi charger can be used for phones universally, regular Android and Apple smartphones can use the same charger. However, the main reason wireless charging never really took off as a proper alternative to regular charging methods is that it has always been less efficient and considerably slower.

With a higher cost of purchase than regular charging cables, they have always had the lower hand. The great news is that fast charging is supported and with the technology evolving we can expect it to be available at a lower price and with quick speeds.

Seeing as Apple is generally the trendsetter in the world of smartphones, it won’t be long until we see more and more Android handsets jumping on to the train, adopting the technology that Samsung and a few others have stuck by for all this time.

What we can expect is more and more refinements to performance that will eventually make it a more efficient and convenient form of charging. The goal of changing how we charge our personal devices will eventually be achieved, but even with this growth, there is very little reason and the chance of it adopting the place of a conventional charging cable.

Regardless of this, there is still the chance of a new technology being introduced that can further lessen the need for wireless chargers which casts a certain level of doubt on the technology.
