As seen in the attachment, my battery health is 91% after 19 weeks and 71 cycles (maybe that's too much cycles for this amount of time?) I am a little worried about my battery life. I seem to not get even 4 hours out of a full charge, and I just use the laptop for basic tasks, such as emailing, browsing, pictures and stuff, screen on low brightness and all. It has been bothering me for a while. I've never calibrated the battery because I just found out about it today, I'll do it later this week. Anyway, after I upgraded the OS for Lion, the battery seemed to be draining even faster, and the laptop seemed to be running hotter. I've read a few comments and a lot of people seem to be dealing with these problems. I tried a few tricks but I am not sure if the problem is solved. I am wondering if anyone has any tips for me, or you guys think I should just take the computer to be checked at an apple authorized or something.
