No. I lost 10% mostly due to it's age. But now I kind of regret that I didn't get it down to at least 80% as apparently Apple instead of servicing the batteries in these 2012 Retina MacBook Pros, they replace the whole machine with the new equivalent for the same money they ask to service the battery as they don't have any parts in stock.
Got a tip for us?

Battery dead after 63 cycles

I would disagree its because of age. I have a 5 year old MBA with 85.8% health remaining at 1228 cycles. So my computer is older, has 16x the cycles and the battery health is almost at par with you. Not using the battery degrades the battery quicker.
It is very relevant......
You said his battery life all has to due with amount of usage (low cycle count), this is completely incorrect.
Apple says nothing about low usage and low cycle count as a factor in battery life.....battery life has to due with amount of charge in the battery and temperatures of battery. Thus my post....
Battery life obviously also depends on high cycle count, but not low cycle count as you suggest.
I did not say that. Please point out where I said that. I said batteries need to be used to maintain health. Which is a 100% factual statement. What you posted is about storing, again not relevant as we are talking about keeping it plugged in 24/7 without letting the battery be used.
And read the next sentence. It's a complete statement. If your not using the battery your cycle count is going to be low. That's obvious. But the next sentence is the meat of my argument and is valid. Again. That has nothing to do with storing the battery.
You seem to be missing my point and that is fine. There is no need to continue going back and forth. It's not leading to anything productive.

If it is indeed 100% factual please point me to information from Apple that says so.
I'd like to be informed if this is indeed true....not hearsay.
Why is my 18-month old 72 battery cycle machine at 96% battery life?
This is one reason why I question this whole theory.

Why does Apple need to be the source. Just google it. Leaving your computer plugged in 24/7 does more harm than good. The battery needs to be used.
The fact that you think 96% health after 72 cycles is good is laughable. The battery is rated for 1000 cycles at 80%. At your current rate you will only get 360. That's 36% of what the battery is rated for. That alone should be your proof.
I'm at 86% health. 5 year old computer. 1228 cycles. I have a half dozen computers with similar battery stats as mine in my family. That alone should tell you something is wrong with yours.
72 cycles at 96% is terrible.
Here are more examples. My iPad Air 2 is 2 years old. 99 cycles. 95% health. It's rated for 1000 cycles. At this rate, it will get 396.
My iPhone 7 Plus. 8 months old. 145 cycles. 98% health. This is rated for 500 cycles. At this rate, I will get 1450.
When batteries are not used, their health deteriorates more quickly. If you want to think that this is incorrect, more power to you. Remember when general wisdom of Lith-ion batteries was to fully let it die at least once a month? Apple even had that on their website. As time goes on, battery technology changes and we learn new things. I really don't think this needs to drag out any longer. So I will leave it at this. Feel free to respond if you want, but I won't any longer.

Go back and read my posts.....nothing laughable at all, except your reply and wasted bandwidth.
96% is what it was right out of the box......zero change in 18-months and 72 power cycles......still at 96%
Zero change!
So, my question & your hearsay remains.......your turn.
Hello All,
just to avoid opening new thread - I have a question - would rMB 2016 or rMB 2017 battery fit in rMB2015 - connector,size etc. If someone has done it or seen it somewhere please let me know as i was searching in google, but could not find any info. I have rMB 2015 and battery health is 84% at 205 cycles that is very low. Need to know as is probably easy to get hold of 2016 or 2017 battery. I am not the original owner, but I assume whoever used the machine before has been keeping it plugged in almost all time hence the low cycle count and low health on the battery.
Thank you.

AFAIK you cannot replace the battery yourself. You will have to take it to an Applestore or servicepoint.
I read in another thread that the 2015 model will get a new 2015 battery. This was after the 2016 model was released.
I should be able to change it, why not. All I need is to know if the 2016 or 2017 rMB fits as I don't want to put another 2015 battery. Is the pinout of the 2016 or 2017 batteries the same as the 2015 battery? Size should be the same and is all glued down to the bottom cover of the MacBook. Does not seem to be that difficult. I have done way more difficult things than that many many times before, so skills is not an issue at all. The only reason I am asking you guys is because I do not want to buy 2016 or 2017 rMB battery and is all different.
Thank You

Good luck on that one, without mangling things or making it look like you used a can-opener.
I'd let Apple do it, cost is not bad considering the huge risk involved!
They wreck it, they fix it....

do you know if the battery health degrades on macbook keep in store for sale?
it some times happens to find deals on new products that is maybe one year old, can they have battery issue?
