The only phone that I've ever owned that poor battery life that could compete with the Amaze's battery life is the original Evo.
In other words, The Amaze's battery life is tied for the worst that I've ever seen from a phone. Any phone.
Custom ROMs should improve things, as will the Anker battery so I hear. I'm going to test these theories.
My goal is to get equivalent usage compared to other Android phones. That will be my standard, not trying to squeeze 24 hours of continuous video watching or something like that. Right now on stock, with my standard usage patterns, it's dead in 8 hours tops. (Again, my other phones would not have been dead)
