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?
