    I have finally managed to buy a copy of Snow Leopard and install it this past weekend, but have been having battery problems on my MBP. The battery life seems to be half of what it was before at best. Could this be a problem with SL or is my battery just dying?

    Wow really?! Does Apple know about this issue? I really love Snow Leopard, but I can't live with such a short battery life :(

    No idea. I installed Leopard again today and my battery life seems to be back to normal...

    Well I got a Macbook Pro recently with SL and no battery problems here.

    Have you been calibrating your battery every 1-2 months?

    Do you get the 7-8 hours of battery life?

    Battery problems

    I recently purchased a mac pro 15" I fully charged the battery when I turned it on, but now if I want to run by battery I am only getting a couple of hours worth. So I end up plugging it in. Any suggestions as to changes I can make would be appreciated,

    I am new to the Mac World

    I did the SAME EXACT thing. I installed SL last weekend and my battery life (with all the same configurations) went from 6 hours to 2:45 hours.

    I almost immediately put 10.5.8 back on because thats one of the top 3 reasons I use a mac. I love the long battery life.

    Well I don't want to get in to the long story but I was basically forced into putting SL back on yesterday and when I did, my Battery life went back up to around 6 hours with the same conditions. Weird ehh?

    That really is weird. Maybe the first time something didn't install correctly?

    I've reinstalled SL 3 times though, on 2 different drives even. Did clean install (got the $10 update disc) every time though, might be why?

    The only time I used up the whole battery was to calibrate it so I don't know how long it would take if I used it normally, but it definitely took longer than 5+ hours.

    Almost immediately after install SL on my MBP my battery health went down to ~50% and SL started reporting that I need to replace my battery. Currently my battery health has gone down further to 36%. I took it to the Apple store and they said they couldn't do anything about it because I didn't have Apple Care.

    From what I understand, there is no real difference between the $10 update disc and the other versions out there.

    Well I think the thing with draining the battery might have some truth in it. With my old MacBook (late 07 I believe) I used it EVERY single day on battery until it was almost dead and until this day I can still get 4 hours out of it. Looks like I'll do a clean install of SL when I get the time, but right now I have so much work for my classes that that would not be a possibility.
