Can a monkey save my iPhone?

Becoming increasingly frustrated with my iPhone's battery life I am turning to the only thing a man in a fix can count on - a monkey - and not just any monkey - this one is a Power Monkey.

Yep, this clever little device - essentially a portable energy store - should give me enough extra juice to keep my blessed iPhone alive after it gives up the ghost after 6 hours of moderate use.

I love the iPhone by why give it so much rich functionality if the bloody thing doesn't have the juice to pull it off for at least a working day.

I depend on mine for work as a lot of people do and the fact that it frequently dies on me is just not acceptable. I should really trade it in for something more practical with a better battery life like a BlackBerry but I just can't bear the idea of any other phone now - so it's up to the monkey to see me through.
