The included battery on the Viliv X70EX lasted 4 hours and 8 minutes using CNET's video playback battery drain test, which replays a video file over and over until the battery expires. This is a more extreme usage of the Viliv battery than Web surfing would require, and the X70EX should last longer in casual use. In fact, we found that when using it around the office it lasted the better part of a day. Still, the X70EX's battery performance is significantly worse than the smaller but thicker S5.
