    ever since i got my macbook around a month ago, my battery hasn't lasted more than 2 hours at the most. i researched and realized i should calibrate the battery, that didnt do anything. then i downloaded istat and it shows everything as fine. i think i got a messed up battery. do you think they will replace my battery if i take it in?

    Go to Apple > About This Mac > More Info > Power, then look at the Health Condition of the battery in the list. If it says Good but is only giving you two hours, take it in and report a fault, they might give you a new battery. If it says Poor, and since you have only had your Mac a short period of time, they'll give you a new battery.

    It might just be because you have too many processes running even though iStat doesn't say so. If you have WiFi and Bluetooth turned on, you will not be getting near 5 hours like Apple says.

    Also, if you play games while on battery power, your battery won't last very long. I only get 1 hour of battery life playing games with only WiFi turned on.

    if your playing any games, going on the web, or using blue tooth, or listening to music. than yes that is correct battery life. to be more efficent turn off programs, sound or also blue tooth and wireless if your not using it.

    what does "about this mac" say about the condition of your battery?

    Amperage is NEGATIVE 1225? o.o

    Edit: Okay </panic> mine says the same thing too... Otherwise I was going to go and have a long hard look in my physics textbooks. Only my amperage reading is -1370 and I've been running on my battery for almost two hours (with three left to go).
