Power Is Always A Problem
The eternal struggle that engineers have been dealing with since we decided we wanted electronic devices sans wires is how to power them. The battery changed things, allowing us to use devices anywhere without an available plug. Rechargeable batteries took that one step further, allowing us to re-use the same battery again and again and again, with very little change in power capacity. However, that little downfall still remains. Reusable batteries, like those in the iPhone, slowly lose their luster depending on how often the device is used and how often you completely recharge it.
For a device that is not only used as a phone, but also as a web surfing device, a music player, and a gaming device, the iPhone performs admirably when it comes to battery life. Still, it isn't without its faults. There are still those who complain about the iPhone's battery having too little capacity, or claim that it fails to recharge completely each time.
App developers caught wind of this problem, and introduced a new app market that we had never seen: battery apps. These apps claim to do many things, such as charging your device quicker than is standard, and some even claim to help restore the original battery capacity of the device.
