If you are a trigger-happy iPhone shutterbug chances are you drain your battery pretty darn quick. The iPhone camera itself is quite power-hungry, not to mention shooting in bright daylight often means you will have to increase the brightness of the screen to get a good look at what you're shooting, thus using even more power. BUT...there's also a few nifty little gadgets and devices around that can boost your iPhone battery life and ensure you're battery is never dead when that perfect shot comes along.
