    Hello everybody.
    I recently bought a MacBook Pro 13.3'' Core i5 and I face a problem with the battery.
    I use it mainly for browsing and for listening to the music on iTunes and then I shut it down (it is always plugged in). I open it next day (it is still plugged in, the charger led is green) and it shows that battery status has dropped to 99%. Two days after and while still plugged in, battery drops to 98% and so on. This means that by the end of the week and while plugged in, it reaches 94% and starts to charge again till 100%.
    I have read this article http://guides.macrumors.com/Laptop_Battery_Guide and I have let the battery fully drain, until it went to sleep.

    I contacted local Apple Support and they informed me that this is the normal behavior of all MacBook Pro batteries.

    Should I be worried? Should I use MacBook Pro on battery for a few weeks, without being plugged in?
