Help Help with battery drain...Juice Plotter

[clone1008]

For some reason in the last couple of days after a full charge Juice Plotter has started showing that my battery will only last about 9 hrs, it used to show between 18 and 20 hours. What should I check that is causing this difference? I haven't done anything different that I am aware of.

Is the battery draining a lot while you're using the phone, or also while the phone is sleeping? If it drains a lot no matter what, have you checked to see if your phone is sleeping?
