Is it true that you save iPhone 4`s battery by keeping it plugged in after it`s 100% charged? the sign in the screen changes as if it is smart enough to use cable power and save battery life...

Know how a laptop works? Iphone is pretty much same principle. Battery fully charged = less charging current needed, therefore the power needed to run the phone is considerably less (aka no battery usage)

As far as actual battery capacity/daily runtime, it all depends on how much you use your phone... If you game/text/surf the internet alot, your battery life will be less than one who just uses their iPhone for email checking.

I always thought that there is some kind of controller in the phone and battery that determines whether the battery is charged. And if it is, it directs the current depending on the phone power need.

Hello,

I think. You can also disable all Location Services, which is a good general rule for conserving battery life, as the iPhone's GPS can blaze through your battery. ...
