Silly people, it is well worth the hassle. I have my wife's cast of 5 and before the exchange it lasted two hours on a charge. I dug out my 4s and had it switched back on by Verizon while my 5 was a way and switched back when Apple returned it. Pretty seamless really and the 5 now lasts all day.On a side note; I have to say I really loved the size and weight of the 4s though ... I am the odd one out I guess but I kind of preferred it. It just feels so 'solid'.
