    Last week only, I was able to use my laptop for about 3-4h while running on the battery however the past few days I've been getting maximum 1h30 of run time on the battery... I calibrated the battery twice yesterday...

    Here is the coconutbattery summarY:


    Isn't it weird that the current capacity is above the original capacity?

    Thanks for you help,

    You must be doing something that involves more power if you're getting a sharp decrease like that. Your battery looks fine.

    next time this happens, go to activity monitor (applications > utilites > activity monitor) and look for the process(es) taking up a lot of CPU... that's your culprit battery sucker
