Unfortunately there is really no such thing as normal....each peron will have different usage percentages......monitor ur particular usages and then you should be able to figure out whats normal for you......menc-settings applications-running apps will help you to turn off some apps and give you better numbers tho
I am evaluating the battery drain with Battery Monitor Widget. If I get 70ma in standby mode I am happy. 90ma is still good, 60ma makes me really happy.
