    After a full charge it only goes up to a 1:47 in time left until it dies WTF? I got this laptop in febuary and it really has never gotten good battery left. 2:30 was the highest I ever gotten with it. Any ideas? I'm using the lower GPU to help battery life and thats not really helping.

    I'm on a desktop right now but go into system profiler and see the capacity of your battery, or I believe there is a program called coconut battery that can tell you the stats of your battery.

    That would be your problem, I'm pretty sure thats a very high number of loadcycles for a 4 month old computer. My nearly 3-year old Macbook only has 375, try doing a battery calibration to be sure, but otherwise phone Apple, they should replace the battery for you.

    That is pretty crazy, my 1.25ghz PowerBook G4 only has 298 load cycles. What's the capacity of the battery on that same screen?

    That is a high amount of cycles, I got my unibody on launch and I'm only on 188 and thats with me and the g/f constantly using it, moving it, taking it to uni, leaving it downloading etc.

    I haven't calibrated it in a while now and it's still at 98% health so with that it will most likely bump it up again like it has every time I've done it.

    What is the health of your battery?

    I'm on the 9600 at the minute with Safari ( about 7 tabs ), skype and mail and I have 3 hours of life predicted so there's clearly something wrong with yours.

    Something is seriously screwed up.

    1) 2.5hours was the highest you ever got, mines at 98% and I couldn't kill it in 2.5 hours if I tried.

    2) if you're really going through 4 cycles per day, and you're at 216 cycles, you're battery health should not be 100% like coconut is reporting....

    contact apple

    I'm confused OP was that photo taken when you had been running off battery power for awhile? Like does it get all the way up to 4600 if you charge it?

    Hi,
    can you download MiniBattery Logger and run it. Then click on the "Details" icon and you should see the same windows as the one I attached. Can you post it please ? There is the "Amperage" value which says how much battery is being drained. If it is low (1000 - 1500) and still you get a low estimation then I guess it's the battery which is not working.

    Full brightness on mine, just browsing, 3:30 . Terrible. Wi-fi on, Hitachi 500 gb 5400 rpm drive, one of the most power efficient. Also only have the integrated 9400m processor.

    Terrible. I expected another 1 hr more my matte penryn macbook pro given that there is now a 73 wH battery and integrated graphics now.

    Skyping in a small window (tiny video chat) for 1.5 hours, now I have 1:20 remaining on the battery. Either skype uses a ton of processor-intensive work or the battery life is bunk.
