This computer's battery design sucks so bad. it seems like everyone has a battery capacity problem
Call Apple Support over the phone. Let them know the issues you have been facing with your battery. If they determine that there is a something wrong with your macbook, they will give you a case number. Then bring it to the service centre for servicing.
My launch unit was replaced a little over two weeks ago by Apple. They diagnosed an issue with a voltage chip on the logic board, and determined that having 89% design capacity on your battery after only 8 load cycles was probably not something that a user should have to deal with.
At first the Genius was going to replace the whole bottom tray (which includes the battery) as well as the logic board, but after I signed to authorize the repair, the system told him to replace the entire machine with a new one. They ordered me a new 1.2/512 on the spot, and I picked it up about a week later. this one is doing a bit better (98.7% after 5 Loadcycles) but that number has been going up and down each cycle. It started at 100.7% and has been down to 97.8% as well.
Another thing that I've noticed about this unit is that the keyboard is a little better. The old one I had had keys that were just not "right", some weren't level - where one side was higher than other, the delete and enter keys were difficult to press in the lower left corner, and they tended to look horrible because of the oil on my fingers after the first day of use. The keys on this one, for whatever reason, don't seem to get as oily as the other ones did. No, I wasn't eating french fries or anything like that before using the other one either.
If you're having problems with your battery, definitely go to Apple and ask them to take care of you. Especially if you have a launch unit.
My battery's manufacture date is 7/6/2015, and my Macbook's manufacture date is 7/20/2015.

So just figured out that all these coconut battery tests along with the system are lying generally. For me, my computer said i had 89% but I went to Apple Diagnositics and I had 99.87% capacity. I will not rely on these anymore
Taking mine to the Genius Bar Tuesday. Mine is down to 91% Health on 14 cycles. 5297mah down to 4831mah. Also, last night the computer was off put not plugged in and the battery totally discharged. Would not even turn on
Mine did a similar thing. The other thing mine did was totally discharge over night with the computer shut off but not plugged into a/c. No idea how this could happen. So, want them to check it out
Just got back from Genius Bar. They ran a test and found a voltage problem. They are keeping it for the next 48 hours to find out what they need to do.
Wow, all these battery problems are deeply concerning. I was going to buy one, and now I'm slowly backing away.
What program are you guys using to check capacity?

Keep in mind that people flock to forums with issues, and those without generally don't. Vast majority of Retina MacBook`s will have no issue with the battery, if it was a widespread issue the press would be on "fire" as Apple is a prime target.

Seems like this voltage issue is spreading, but it isn't. These genius bar employees don't know how to properly test the computer. YOU NEED TO HAVE THE COMPUTER PLUGGED IN when running diagnostics. Even their damn iPads state in a yellow box to redo the test with the charger plugged in. I have gone through five computers with each computer being the voltage issue. They finally found out that the computer needs power when the test is running. Also, coconut battery is a very rough estimate. 90% for me turned out to be 99% on their diagnostics. If you have time, go check it, but I bet you nothing is wrong with your computer. Yosemite just does not have good software to measure the new capacity for the batteries. Sometimes, with my computer charged for a day, my battery capacity is 102% while my battery is somehow charged only 90% of the way to its design capacity.
Actually when this was all going on I was using El Capitan so not sure if that had anything to do with it. The Genius asked me for my charger when running the tests at my appointment but I did not have it. Offered to go back out to the car and get it but he declined. So, it may be very possible as you say that the voltage and battery tests indicated problems because the computer was not plugged in. Unfortunately, I did not know this when he was testing and they now have the computer for repair. Still does not explain the loss of battery time remaining over the last few weeks and the total discharge of the computer over night when turned off but not plugged in. The Genius did say that my Macbook was the first one they had seen brought in for service. Also, the store was a mad house. Not even a seat at the Genius bar and I waited 45 minutes beyond my appointment. Maybe he just was in a hurry to and that's why he did not let me go for the charger. At any rate I guess I will no something in the next few days. Thanks for you input on this.
Then maybe you can explain why my rMB and the vast majority don't have any issue, think about it...
Q-6
Exactly what happened to me. its always so busy they rather replace it. Good luck on the new computer!
just got back rMB from Apple Service Centre and they can't detect anything, battery working fine.
BUT they cant explain why my rMB lost 10% Battery Design Capacity within 2 weeks!
also received an Case ID: Will call Apple Support for answer.
PS; there' no Apple Store in Singapore only authorised Apply resellers and their Service Centres.

I don't normally recommend this action, however it may be revealing in your case; fully discharge the MacBook and then leave it to charge up full over night, then check the battery status.

It may be no more than the SW calibration of the battery is "out" however the values can go down. I would also try to charge it in a relatively cool environment. My own 1.2 rMB is holding up fairly well, equally the average trend is clear (attached)
If your rMB does drop battery capacity significantly again, I would contact Apple directly and see what they say.

Just a quick question for all. They are giving me a new in the box replacement Macbook. I was entertaining the idea of just asking for a refund or selling it and going to a MBP 13" retina. I have an iMac so I don't really need any of power of the MBP but just an uneasy feeling about the Macbook and this battery issue. Just something I am thinking about and would welcome anyones thoughts on it.
I actually might just return it and hold out till the new skylake computers are released
You will find similar concerns over in the MBP forum, for the most part people are getting alarmed about a few failures. If you want the Retina MacBook keep it, just use your Mac normally and charge it with the supplied charger.
If you look at the trend for the 13" rMBP it`s not dissimilar to the rMB over the first six months, if anything the range of the 13" indicates more systems with significant drops in battery capacity (green silhouette) over time (23 months).
If your MacBook has an issue with it`s battery, the problem will surface rapidly, and you will likely be in the minority, as can be seen from the charts.
