I recently upgraded to CF03 and use SPB3 as well. While I don't get 2-3 days, it's definitely better than yours, which would lead me to suspect a hardware issue. The only other thing I can think of is if you have connection issues. I work in a basement that has a terrible signal. I've started turning no flight mode at work, but before I did that my fully charged battery would be drained by 10 am. The phone was constantly trying to get a new connection to the internet or the phone tower and it drained like crazy. Just some data points for you to think about.
