And truly surprising that when you add faster components, bigger screens and many, many more functions, phones require additional battery power. At this point, my phone can make it from my wake up at 7am easily until 3am if I'm out late, and that's enough that I don't have to worry about it (though obviously I won't say no to battery improvements).
I use to be able to get weeks of use from a single charge of my old Motorola Razr.
