Battery life of less than a day on 4G is disappointing...
You can turn on/off 4G with one button so why wouldn't you to save battery life ??
Its not like calls when you don't know when its coming.
You know when you are using data heavily so turn on 4G when neccessary.
I have the HD2 and the battery is only 1230mah and its fine for me.
The EVO is 1500mah. It should be more than fine.
