So for the most part, I'm pretty happy with my new MPB [2.53], except for charging times. When I first turned on my MBP it was at about 68% battery, and it took quite a long time for it to get to 100%. At first I thought to myself "Its probably because I haven't calibrated the battery, I should do that now". So right now, I've been charging from 0%. Its been since 7:00pm, and it is now 11pm and its still charging, right now its at 95% with 50 min still remaining. Thats nearly a 5 hour charge .I've only been browsing the web, listening to iTunes [total CPU usage 8-12%], and my brightness on one bar. My previous PowerBook had bigger [58 watt-hour] battery, and a 65 watt charger, yet charged in about 2 hours. BTW, I'm happy with the battery life, I've been getting about 4 hours [give or take], its just the charge times that are frustrating.
