So I had my iPhone for just over a month and I like it a lot. My only thing I noticed is sometimes when someone calls me I have an option "accept" or "Decline" and sometimes I just get "slide to answer". Why is that? Is it something with the settings? I wish I can get the Accept and Decline all the time when someone calls. Also whats the best way to make the battery last long? So far i been draining the battery all the way and then charge it, is this the best way?
