Battery life...that is exactly why I have the phone I got. Granted, it's freakin' slow, now because I've got too much junk on it. I'd get a new one in a heartbeat if it wasn't for Verizon's silly policy of having to pay full price for a new phone to keep your unlimited data plan. I'll probably upgrade to the Note 4 when it comes out, if it outshines the latest iPhone. I'm sure it will. It'd better...or I'll wait longer.I hope manufactures take on the attitude of, "My battery is bigger than yours." We need that. My Droid RAZR MAXX could be twice as thick for all I care. A 6400 mAh battery would've been awesome. Overkill? No. Some of us forget to charge our phones.
