    Mid-2009 MBP 13" Battery Life
    Is 3-4 hours normal for my 13" 2009 MBP? I used to get ~7 hours with Leopard, it dropped slightly with Snow Leopard, now with Lion, I only get 3-4 hours.

    In system information, it says the following for "Power":
    Charge Information:
    Charge Remaining (mAh): 2873
    Fully Charged: No
    Charging: No
    Full Charge Capacity (mAh): 4954
    Health Information:
    Cycle Count: 348
    Condition: Normal
    Battery Installed: Yes
    Amperage (mA): -894
    Voltage (mV): 11301

    Is this normal?

    (I've already done the SMC reset.)

    My 2010 13 inch has around the same amount of cycles but it may be possible that your battery is going dead. You could partition the drive with leopard or snow leopard on it to see if your battery life is any longer with them still.

    That's a really good idea. I can't believe I didn't think of that...
