i am on a maxx, they cahnged my razr to a razr maxx. I was thinking, maybe sell my maxx out right with otterbox case, and then buy a used s3 or even a bionic with extended battery, something that gets 5+ hrs of use
If you are on the Maxx now then we should figure out what is causing your bad battery life, you are not going to find a phone out right now that can beat the Maxx in those terms.
Do you have it set to 4G all the time or do you use the TB App to change it to CDMA only? Try that battery monitor I suggested or even what does your stock battery meter say is using all your battery now? Screen should be the top contented for battery consumption, if something is using more than the screen that might be your problem.
