Wireless charging is something iPhone fans have been eagerly requesting for. Given the yesterday's details of the iPhone 8's alleged switch to forged stainless steel for its chassis, Apple will finally be able to exploit one of the new technologies that iPhone is not yet capable of and that is charging wireless.

A toughened glass for both the front and rear panels is required on Apple's apparent all glass construction usage which would also sandwich a strong central chassis of the forged steel. The said glass is definitely not just an ordinary sheet of glass.

It is somewhat similar to Corning's Gorilla Glass that will offer possible great robustness for iPhone user's daily use. The mentioned switch from a full metal backing plate to one made of glass will not only give the new iPhone a stylish look, it will also pave way for considering wireless charging.

There are a number of standards around wireless charging that many smartphones adhere such as the most common method, Qi. Apple may possibly work its own format too, but note that all its physical principles are alike.

Current is passed through electromagnetic induction and through a coil of wires in the charging base. A current will be made in any coil of wire close enough to the charging base which can then be used to charge a battery.

Metal black plates prevent electromagnetic induction which makes wireless charging not suitable with the current design of iPhone. To be able to integrate wireless charging to an iPhone or any smartphone or tablet, the back of the device needs to be plastic, ceramic or glass. There aren't enough details if Apple would really include wireless charging in the next iPhone, but it is a major possibility.

Wireless charging feature for iPhone 8 answers the ongoing issue of low battery life. "Quick charge" may be another option, wherein users will be able to charge their iPhones in a short period of time and would still receive a significant increase in its battery life.
