I have Sprint service, and have had my Samsung Galaxy 3 since launch. The first couple months the battery lasted the whole day without any problem. The last couple weeks the batter is down to 20% by noon, and I haven't downloaded anything new that would effect it. It's since the last time the phone did an update, it just sucks. My Girlfriend has one with T-mobile and is experiencing the same thing since a phone update a couple weeks ago. Anybody else experiencing the same thing? It sucks having to throw the thing on the cigarette lighter charger in just 4-5 hours. I would trade back to my Epic 4G if I could, the phone is awesome, but the battery dies way too fast...
