    Since going directly from Panther to Tiger 10.4.3, I'm only seeming to get 1 hour battery life, whereas it was more like 3 before.

    Any reasons for this?? Any suggestions what I should do?

    Using Coconut battery application it says this:

    Current Battery Charge = 420 mAh
    Maximum Battery Chaarge = 2115 mAh
    __________________________________

    Current Battery Capacity = 2115 mAh
    Original Battery Capacitiy = 4400 mAh


    So it seems to be telling me I've lost half the batteries original capacity!!
    Any clever tricks like zapping PRAM - pressing reset buttons ets??

    thanks all - and yes I've searched



    :( :( :(

    Have you calibrated it recently? Charge it up, fully discharge it and then fully charge it again. :)

    Oh, and that PMU reset is a good idea.
