Not sure what my battery was at out of the box, but I did the calibration and now it is at 99%. 6888 out of 6900

Do you calibrate your battery the first use?

Well I haven't actually got a chance to use the computer I did the transfer data from my old one then shut it down It was fully charged during that. I just turned it back on and ran it down to about 84% decided to plug it in and do the battery calibration. Should be fine when finished.
Take a look at this:
My PB has 80% of the original battery capacity remaining after nearly 6 years. I leave my PB plugged in 24/7 unless I unplug it to use on a couch or bed. I do let it sleep at night, plugged in. When it is unplugged I usually run the battery very low (ignore the warning and go down to a few percent) before plugging it back in. I performed the recommended initial calibration and since then have performed maybe 2 or 3 intentional calibrations. Other calibrations occur when I forget to plug it back in, which is not very often. I guess what I'm saying is that if you intend to have a mix of both plugged in and battery powered use, don't worry too much about regular calibration.
On the other hand, if the laptop will be used as a desktop replacement and never unplugged I would highly recommend a regular calibration routine.
Adaptive Charging
On Apple's website, it says that the batteries in the new MBPs use a process called Adaptive Charging. I'm not sure if this is just with the new MBPs or not, but the process sounds a lot like what a Battery Tender does.
For those who may not have heard of this device, a Battery Tender is a "smart" charger. It's supposed to be able to correctly charge your, say, motorcycle battery properly depending upon how much of a charge it currently has. It's safe to plug a fully charged motorcycle battery into a Battery Tender, as it will detect its charge level, and just supply it with a "float" charge when needed. The Battery Tender will revert to deep charging for a severely drained battery, and can even "repair" a "dead" battery. Altogether the Battery Tender is supposed to lengthen the lifespan of a battery you entrust to its care, and there are many motorcycle enthusiasts who plug their motorcycle batteries in to Battery Tenders or similar smart chargers every time their bikes are parked in the garage.
(Recommend Googling the above to see for yourself, but that's an accurate summary as far as I can recall.)
At any rate, Adaptive Charging sounds similar based upon the few paragraphs I could find on the process on Apple's site. If that's the case, I'd imagine it would be safe or even good to leave your MBP plugged in all the time.
I'm not sure how that might possibly conflict with the advice to regularly calibrate the battery, though.

wow very impressive. I would love my new macbook pro battery to last that long
I just dropped a new HD into my i7 MBP and am in the process of re-installing some apps. Do I need to run the battery calibration again?
No, not for a new HD. If you get a new battery, yes.
No, it's not the same as a battery tender. And Apple specifically states:

Oh dear, oh dear, oh my paws and whiskers.
Iam an utter new boy, I believe the nomenclature used is a switcher.
And this 'permissions' business is news to me.
Am I missing out.
Have I been doing everything wrong so far.
Oh, and whilst I am here is there a way to maximise a window a'la PC style?
I would love to press a button or two and have the window in question fill the whole screen covering the dock at the bottom?

There's no need to worry about repairing permissions unless you're addressing a particular problem. If you're not experiencing a problem, you have nothing to worry about.
Mac OS X doesn't work that way. While it took me a few days to get used to it at first, I've long since learned the benefit of not filling the entire screen with one window (unless it's a full-screen movie, photo viewing, etc. which have full-screen options).
By the way, you may find value in using MRoogle to search the forum, as it will usually find answers to most of your questions.
so is it normal for the battery to run much less on the first go? I just got the computer today and am in the process of running it down to 0 now and it seems that it will last 6 hrs on light use versus whatever it is supposed to be (10 according to Apple)..will calibrating it increase the battery life, or should I expect what I am getting now?
Thanks
Thanks
It should help. Before I calibrated when i unplugged the charger with nothing running but the screen on 50% brightness it showed me 13:46. Now after calibrating with the same screen brightness but safari open with this tab it shows me 14:15. I know it's just a calculation, but at least it's something.
