Apple - you know the company, the one with all the silver and black expensive gadgets - is looking at the age old problem of battery performance in phones.

The new technology has been uncovered in a patent by AppleInsider, which looks at increasing the power density in batteries - essentially keeping the same volume while improving the amount of juice inside.

This is achieved using a "multi-step constant-current constant-voltage (CC-CV) charging technique", which is science-speak for 'more sparky, same size-y'.

Battery to the Future

Such steps forward are pivotal if today's smartphones are to continue on the same path of more feature rich in a thinner frame, and Apple notes that this could be used for increasing the amount of tech in the same footprint, or making the phones even teenier.

But it's not all good futuristic science news... the technology is susceptible to battery life degradation when temperatures fluctuate and if the charge in the unit is kept too high, this will also hurt the life-span of the power-pack.

We hope Apple is feverishly beavering away at this new technology, honing and polishing until it gets it just right - there's no way we'll be seeing the improvements in the next iteration of the iPhone, so does the iPhone 6 suddenly make a lot more sense?
