    My new MacBook Pro seems to take a long time to recharge the battery. I noticed for example that the last 12% to 100% takes about 90 minutes (88% to 100%). Is this normal? Thanks

    I dont have yet a MBP but I'd say that this is quite fast for a charging time.

    I've noticed the same with my new MBP. I am not sure that this is normal for a MBP but my late 2007 model MB definitely did not have this issue.

    My previous model did not do this either

    This is somewhat normal. It is referred to as trickle charging. 90 minutes seems to be a bit long, but it typically takes my machine about half an hour to get from 95% to 100% (this has been the case on my previous macbook [2 batteries] and macbook pro)

    EDIT: It is referring specifically to lithium-ion iPod batteries, so I am not sure how this differs with the lithium polymer in the new machines, but they say this:
    [It takes] about two hours of charge time to power an iPod to 80% capacity, then another two hours to fully charge it.
