The Epic 4G Touch is definitely one of the better Android phones when it comes to battery life. Its 1,800 mAh battery was able to power through a full day with moderate usage and even idled without issue.
I also appreciated the option to toggle between 3G and Sprint's 4G WiMAX network. With only 3G on, I was easily able to get through a full day with moderate usage. With 4G WiMAX enabled, it's obviously a different story.
