So many people I know (especially in the US) constantly carry their iPhone charger cables with them when they leave the house. We need better battery life!!! Though each new model has increasingly better battery life, it also has increasingly better apps/options so we are increasing our usage. I think this is something that Apple should focus on. A dead battery renders all other amazing parts of the phone useless.
90% of the time I don’t need nor want my apps to multitask.The home button should by default close the running app and for example swiping two fingers downwards across the screen to send the app in multitasking.
It would also be great if we could swipe the apps out of the multitasking bar to close them.
Replace the iPhone standard connection with a mini USB connection this will allow much more flexibility to charge the iPhone without carrying the Mac cable all the time. Mini USB charger is becoming the standard for nearly all the new generation of mobile phone, Why not the iPhone5?
