6. Serious Battery Life Improvements
Given that abilities between devices are shoring up, it's clear battery life is going to be the more important spec going forward. If you can't use it all day without having to charge it, there's a problem. iOS 7 should improve on battery life from existing idevices by at least 10 percent. There's gotta be a way of making existing iPhones last longer without diminishing capabilities.
I'm cool with things if it means that you have to learn how I use my device and then only turn certain radios on when I'm in specific locations, or at specific times of the day, etc. What I need is to be able to use my iPhone for more of the day without fearing that I'll run out of juice.
