Here's one for #Apple users: Your phones'battery will soon be lasting up to a week from a single charge. Yes, a SINGLE charge!!

It seems Apple is determined to improve the battery life of its various devices after years of complaints from owners.

The tech firm has been awarded a patent for a 'fuel cell system' that would replace the clunky, toxic batteries found in its Macbooks with cells that have the potential to last 'days or even weeks.'

It is the second time, in a matter of weeks, Apple has been reported as looking to revamp how it powers its devices using the smaller, more environmentally-friendly technology.

The patent was filed to the US Patent Office in March this year and has already been awarded.

It details a 'fuel cell system for a portable computing device, comprising a fuel cell stack which converts fuel to electrical power [and] a fuel source for the fuel cell stack.' 

The files specifically make reference to the MagSafe connector seen on Apple's range of Macbooks, suggesting the cell system would initially be designed for its laptop range.

However, the technology can be made smaller, which would make it suitable for the iPhone or even the Watch and it may be introduced in future models.
