The HTC Evo 3D ships with a bigger 1,730mAh lithium ion battery than the Evo 4G and has a rated talk time of 6 hours. Though we’re still conducting our battery drain tests, we’ve already noticed better battery life in day-to-day use. Starting with a full charge in the morning and with moderate to heavy use (including playing 3D games and video), we were able to go a full day, sometimes early into the next day, before needing to recharge. As soon as we complete testing, we will update this section with our battery talk time results. According to FCC radiation tests, the Evo 3D has a digital SAR rating of 0.885W/kg and a Hearing Aid Compatibility Rating of M4/T3.
Now that is a site doing some battery testing folks! Battery myth debunked!
