Oh that makes more sense now. You don't use your phone. For the rest of us that do we're averaging about 10 hours. An extra 200MAH won't do squat for us.
Actually, I use my phone plenty (what I would consider light-moderate use during the week and moderate use on the weekend, but I would not consider myself a "heavy" user), its not just sitting in my pocket or desk all day long with the screen off. While everyone's use is different, I do all the normal things that anyone would do with this phone: emails, texts, calls, games, apps, streaming audio, internet, facebook, chat, camera, time & weather, calendar, news, etc. Sorry you only get 10 hours, sounds like you are a heavy user and need to keep a charger handy or buy the HTC 2750 extended battery instead of the Seidio.
