Hihi, I am not tech savvy and hope that someone can enlighten me

 

I bought my MBP 15" on 26 Nov 2011 (Singapore).  I only realised after 1 month later that the MBP

had more than 15 battery counts when I only charged for less than 5 times !

 

And lately, I notice as well that under Battery Capacity (with CoconutBattery) that the Design capacity is 96900 mAh but

my Current capacity is 6751 mAh after 29 battery loadcycles.

 

CoconutBattery shows that age of my batter is 7 months....it is only 18 May 2012..and it should only be less than 6 months

since purchase date...and I do not understand why is that so as well

Is this acceptable for a MBP?   Thank you very much in advance

    It can only mean that the the computer was not new when it was sold to you. I received mine from the Mexican Apple Store (custom order, so was delivered by DHL) in 9 Dec 2011 and the cycle count was at 1. Capacity was at 7018, and it actually improved after a few cycles, peaking out at 7160. Today, 21 weeks and 24 cycles later, it holds at 7034. According to both coconutBattery and Battery Health, the standard capacity for these Macs is 6900.

     

    If possible, I would complain with the store.

    Check with Apple to ensure it is registered to you and that you are getting the full 12 month base warranty.

     

    No idea what kind of pressure you can bring to bear on the store for having sold an evidently used product labeled as new. In the US, any semi-competent lawyer would be salivating at the possibilities...

    Still, are you going to get 3 years or less? Is coverage going to end on 26 Nov 2014 or before? Can check here: https://selfsolve.apple.com/agreementWarrantyDynamic.do

     

    coconutBattery merely displays the info it is gathering from the computer, as also shown in the System Profiler. And any Apple tech can retrieve that info with their diagnostic tools.

    After reviewing the results you got from the Warranty link, we can agree that you seem to be all set for now and the only nuisance is the battery's age. But that is covered so, should anything go awry, only irritation will be getting the part replaced. Apple says that if  real max charge drops below design max charge  (6900) before the battery has 1000 cycles, you are eligible for a new one.

     

    Seeing that you've already discovered coconutBattery, it seems you're pretty much well on the way to wisely managing your resources. With these Macs twin GPUs, you may also want to download and install the gfxCardStatus utility ( http://codykrieger.com/gfxCardStatus ): it displays a i or d in the menubar, indicating which GPU is in use, and you can force the use of one or the other. The AMD Radeon gives stunning fast graphics but eats batteries for breakfast. Another useful tool for keeping an eye on all of the Mac's doings is the iStat Pro dashboard widget ( http://www.islayer.com/apps/istatpro/ ).

     

    Enjoy your Mac!

    Heh, heh, it's like when you take the BMW out for a spin the first time, right? Have trouble finding out where the A/C button is amongst the bunch....

     

    Anyway, don't trouble yourself for now, you'll get the hang of things soon enough. And before we know it, there will be the dilemma of whether to keep this kitty or migrate to its soon to be born new brother, Mountain Lion!

     

    Have a good weekend!
