Man, i'm sorry i'm posting so many new threads, but I just bought my n770 off eBay and I need to know if something is wrong so I can return it before it's too late.

Just this morning, I unplugged my 770 from the charger, fully charged, and it immediately flashed a low battery warning followed by "recharge battery", then it shut off. This comes following a period of very bad battery performance. I was running OS 2007 HE before, and I couldn't even get 4 hours of standby time. I thought that it was just the experimental os, but I just reflashed with 2006, and the problems continue. Just yesterday, I unplugged it, again fully charged (supposedly), and it instantly went to 3 bars. It was at 2 bars in about half an hour (of usage) and was dead within 30 minutes thereafter. That's an hour of usage, nothing close to what I should be getting. Is there anything I might be doing to produce these problems? I got an amazing deal on the 770, and it's perfect otherwise, so I would hate to send it back.
