... after disconnecting from the ac adapter, and the percentage before was like 98-99%.. is this normal?

its brand new, just got after the christmas. mbp 13" standard configuration, but with a ssd..

i did not calibrate the battery, since i thought that this wouldnt be necessary for new products..

have any ideas? thanks a lot already..

edit: and now its recharging again from this state, i am at 65%..
 
hmm, i didnt know that the calibraiton should have been done shortly after getting the laptops.. as far as i get this, it s just for accurate reporting of the battery status.. so it's normal and i didnt get a bad battery?

edit: coconutbattery says that my mbp is 4 weeks old, is it ok now to calibrate the battery? or have i walked into a dead-and-road?
 
You can still do it. Calibrating will make the figures more accurate. If you still have issues after calibrating, then it might be a bad battery

Read the Battery FAQ that wordoflife posted. It will tell you how and when to calibrate and how to care for your battery. It has all your answers.
 
follow those directions ... which is basically to kill the battery till dead/sleep, then fully charge it and allow it to rest for a bit after you unplug it.
 
I don't think that is calibration related. I would calibrate anyway and if it still does that, have Apple replace the battery under warranty. Lithium polymer batteries last a loooong time before they have any type of 'dump' capability wise.
 
well, i wasnt doing anything particularly.. just surfing on the web and listening to some online radios.. the second i plugged it out from ac adapter, it showed the classic "calculating..".. and then 59%.. the thing i forgot to mention is that even the mbb 4 weeks old is, i havent been using it for like 2-3 weeks.. after i first got it, i opened it for the first time, installed the os, charged it fully and put somehow aside, because i was going to a vacation.. and since i am back, i have been using it for like 2-3 days.. and it seems that i am not going to be able to calibrate the battery following days, cause i am going to be away for some time.. could that cause a problem, if i wont calibrate it as soon as possible?

Unplug it, use it, and let it shut off by itself - then recharge
