The Nokia Lumia 920 is on its way to the market soon. The phone itself seems like a solid Windows Phone offering, but one feature really sets it apart from the competition. This will be the first phone to ever feature a built-in inductive wireless charging system. Wireless charging is nothing new to Android devices through the use of special accessories, but we’ve yet to see a built-in solution from any of Google’s hardware partners.

Android devices often led the pack when it comes to adopting new features and technology, and likely built-in inductive systems like found in the Lumia 920 are already in works. Perhaps even in devices like the rumored Samsung Galaxy S4? Inductive charging isn’t the only wireless charging option possible.

A new patent from Apple suggests that Tim Cook and company are working on an electromotive charging system. In theory, a movement-based charging system would mean that the devices would never need to be plugged into a charger at all.

The idea with this method is that flat coils would generate electromagnetic induction through the use moveable magnets. As you walk around with your phone in tow, the magnets would slide past these coils, and it would somehow manage to generate electricity. I won’t pretend to fully understand how electromotive charging works, but it certainly sounds cool.

On the other hand, a simple patent doesn’t mean this is something that Apple can bring out any time soon. It’s also possible that Apple’s system might not generate enough power to keep the iPhone going without traditional charging. If that was the case, this might just work to generate a little extra energy that allows the battery to last longer than normal.

More than likely such a solution is still many years away. It’s also more than possible that an Android device will beat Apple to the punch by providing something like this, if not a better solution. What do you think of the idea of a movement-based charging system? Would you like to see something like this hit Android devices, or not?
