As the first Google Glass units came off the production line and started reaching members of the early-access Explorer program, we have first impressions. Unfortunately, the first feedback is bad as it seems that the battery life is extremely poor.
According to Robert Scoble, one of the first consumers to try out the Google Glass, explains that "one six-minute video took 20 percent of the battery." Google did mention that Glass can last up to one full day of typical use, but applications such as video recording and have a greater impact on endurance. Nonetheless, this could end up being a deal breaker for a lot of users and even it's not the final version we doubt anything can change.
