How long are those movies, about 1.5 - 2 hours? I just tested an hour long video and my battery went down 10%. Wireless was tuned off, and screen brightness was in the 30-40% range.
When I look at my battery usage, the android system, android os, and media server take up the most power (about 50% altogether). But I wouldn't know where to start to improving battery life.
With wifi turned on and doing casual web browsing and watching YT, I still get about a 10~15% decrease in one hour.
