iPhones are thin in the grand scheme of things and you can only pack so much punch into the battery life. If compared to a human, an iPhone is that skinny it needs a good home-cooked meal.

If a home-cooked meal is not that easy to find, then an energy beverage might be more the ticket. The Morphie Juice Pack is a rechargeable lithium polymer battery that says it will add up to an additional six hours of talk or surfing time to the iPhone. The pack adds about a centimetre of thickness to the phone while still offering a pass-through USB for syncing and charging.

The Morphie Juice Pack is available through selected retailers in Australia or online.
