Well here is some things you can try to improve battery life:
1. change to stock ROM and see if the problem persists
2. try some battery saving tips such as setting brightness low, turn off auto sync and background sync.
3. not sure if this would actually work, but try downloading battery monitor from market, and if it has not detected it is a 2000mah battery, change it to 2000mah.
4. it is a faulty battery try a new one.
