    I have noticed that my battery seems to be draining fast while the macbook is sleeping.

    Its a blackbook, core duo, 2gb ram.. According to iStat Pro my health is 92% and the cycle count is 102.

    Earlier today the battery was at 80% i just opened the mac up to write a email and closed it right back.. about 3 hours later the battery dropped down to 76%..

    Seems kind of hight 4% for 3hours..

    Am i just worried or does that seem right?

    That's normal. I don't have an exact number/time and probably varies from user to user but the battery will drop approx. 1% each hour.
