I have owned an Evo for about 18 months now and while I love it, I am always interested to see what some of the newer phones have to offer. The only complaint I have about my phone is of course the battery life. I have 4 batteries for my phone and I just switch them out when one of them runs down. What I want to know is since I have 4 batteries, is there a way I can find out which other phones would use the same batteries so I can still use my extra batteries with a new phone?
