I have an iPhone 4, 32GB. So far I am impressed with everything but the battery life. It's much better than my 3G. But I was just hoping for much more from the battery. So that brings up some questions for me. How do you maximize your battery life? And I'm I'm not talking about lowering the brightness, not playing games, etc... I'm talking about the amount of time it holds a charge when it's brand new, compared to how long it holds a charge a year later, usage being the same. I know not to leave it in the car when it's really hot out. But what about the way you recharge it. Does that matter? - Is it a good idea to let the battery run all the way out? Or should you avoid that? - Is it okay to keep recharging it when it gets down to 75% or should you wait until it's lower like down below 50% or 25%? - When you charge it, is it best to not stop charging until it reaches 100%? These are questions I have had for a while but I never seem to be able to find answers to them. Thanks!
