I’ve had the problem that my IPhone is already pretty low on battery by the time I’m on my way home from work. And it’s not like I use my phone overly much – just the usual business calls, a bit of gaming during lunch break. I’ve been told to buy one of those backup batteries, but they’re SO expensive. I just decided to buy one of these here: Portable USB Cable for iPad and iPhone4. Only S1.80. It has pretty much solved the problem as I can keep a cable at home and the other at the office.
