    Hi guys,

    I just bought a used MBA 2011. Great, except concerning the battery, which gets depleted really fast.

    I ran Coconut battery in order to check its state, and it says that the battery is in good shape. This is strange.

    Any idea ? Here is a picture so that you can see what I mean... It says "3:39 left" on the top, with 91 % of the charge. Yet the battery's health is great.

    From the BATTERY LIFE FROM A CHARGE section of the following link:
    The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

    Thanks a lot, I'll make sure to read that. I quickly read the beginning, and before I posted I checked the CPU activity. I have had a white macbook for 5 years before this MBA, so I know that the estimates may fluctuate. However, in my case they never fluctuated beyond very low figures, with CPU idling. :(
