Hello. I bought a Macbook 2.16 GHz 1GM Ram C2D exactly one year ago. Now, according to iStat Pro my battery is still at 100%. Is this normal? I'm not complaining at all but I read a lot of threads on here of people who had their Macbook for 6 months and their batteries were at sub-80% health. My battery has gone through 151 cycles. Is that normal? I normally keep it plugged into the power adapter but I do run it off battery power until sub-20% charge occasionally. Now my roommate bought a Macbook in April, and I think it's the same model and specs as what's available now, 2 GM Ram, 2.4 GHz, yet when I used his Macbook off battery power it loses it's charge MUCH slower than mine. I can go from 100% to 80% in 15-20 minutes yet he'd still be at 92-93%. UPDATE: It is now (2) TWO years since I bought my Macbook .. and iStat Pro still shows that my battery has 100% battery health. I have gone through 236 cycles as per iStat and the Mac's System Profiler, and System Profiler says my battery condition is GOOD. Is this normal? I thought the more GHZ and RAM the more it drains your battery. Maybe I had a lot more applications open or something..
