I don't do any battery consuming things, all i do is text really, but sometimes use the browser for like 5 minutes.. It goes dead in about 4 hours, probably less if i was on it constantly. It even drains battery by just being on, as soon as i turn on the screen, the phone rapidly heats up to the point where it gives me a message that the screen is dimmed to prevent burn in, it all happens in about 5-10 minutes.
When i check what is consuming my battery, it shows the screen takes 80%. Nothing running except the android OS, UI, and some homescreen widgets. I tried turning down brighness and 4g, but it still went from 40% to 10 in about 10-20 minutes.
This is pretty crazy, i'd expect at least 8 hours on this. Also what is up with the heat? It nearly burns my thumb using it.
