So, I know that voice calls are normally pretty battery intensive, but when I had my Incredible, it was easily good for a few hours of calls without running the battery dry. Over the past few days though, I've noticed the Thunderbolt very quickly drains my battery. Today has been the worst I've seen. Battery just turned yellow, so there's 25% or less left. 50% of my battery usage has been voice calls. How long have I been on the phone for these calls? 12 minutes.....This would give me roughly 30-45 minutes talk time from a full battery to empty. Anyone else having this problem? Any solutions?
