I think reviews overstate the battery life matter. Mine drops to 40-50% after a day of use from 8am to 10pm. I don't use any fancy app killers or anything like that, I just only turn on 4G and GPS when necessary, have my 3G radio set up to activate on-demand, and rely on Wi-Fi for my data needs (My apartment, favorite bar, and office all have Wi-Fi). The first few days of ownership I was actually struggling to wear my battery down to <5% so I could do a full charge cycle. Note: I have a "Rev B." Evo. My biggest complaint is that 4G service indoors is awful (close to non-existent unless you live in a house made of paper), and outdoors it is very latent even with a strong signal ( 200+ms)
