No matter how powerful and energy efficient our smartphones get there is always one thing we'll need more of and that's battery power! However, it looks like Nokia is one-step closer to delivering the next-gen charger and they're developing a technique to charge your smartphone without having to plug it in. Read on to find out more about the Nokia developing the self-charging smartphone...

Fancy charging your smartphone as you move around? Well, it seems that Nokia is in the early stages of developing such a charger. A story popped up over on stockwatch that suggests that Nokia is working on a battery charger that draws its energy from the every day movements and motion the average smartphone is put through.

Apparently, self-charging through kinetic motion has been around for some time but it usually only applies to bigger and heavier machinery. This is due to the need for a large power frame and radio transmitter connected to the battery and completing the power circuit.

The trick with the Nokia technique is that this frame is a great deal smaller. Sure, it still uses strips of piezoelectric crystals that when compressed produce the juice to power the smartphones. what's more, Nokia has juts patented the technology - check out what it looks like in the images below.

It's still early days for this technology and we're hardly likely to see such a device in commercial use for some time. Still, it's good to know that Nokia is working at cracking the need to charging our phones every few days or so.
