Q-6
staying in the 'civilized' world for three weeks now and on regular mains.
My battery health has since dropped from 93% to 88%. 108cycles in 4 months. 4666. Original max was 5297.
Not impressed but enjoying my machine a lot.
My experience with MacBook Pro is quite different: I just sold one 2011 model with 500+ cycles still at 94% health. The previous 2009 model I sold after 2 years with 280 cycles and 95% battery health.
My wife's MacBook Air 11" is almost 5 years old, more than 300 cycles and still 88% of battery health.
It's hard to make a credible statistic with a few cases, but it seems that the battery of the MacBook is wearing quite fast. I see many cases of health under 90% after a very few cycles....
Unfortunately, I now tend to agree as can be seen below. The trend is now clearer, with the drop off in capacity for the rMB being more aggressive than 13" & 15" rMBP`s. Data from CoconutBattery; light dotted green line is the average battery capacity.
2015 1.2 rMBP
2014 13" rMBP
2012 15" rMBP
Q-6
Owned my rMB 12" since June, here's how mine stands:
Charge Information:
Charge Remaining (mAh): 5088
Fully Charged: Yes
Charging: No
Full Charge Capacity (mAh): 5141
Health Information:
Cycle Count: 37
Condition: Normal
Battery Installed: Yes
Amperage (mA): 0
Voltage (mV): 8654
It will go anywhere between 8-10 hours on a single charge. I have no complaints thus far.

This thread has been super helpful. I've been debating between the 12" rMB and the 13 rMBP, and my current battery in my 2012 MBP is already bad so I don't want that to happen so soon on my new machine! XD
Well, your 2012 MacBook Pro is from ..... 2012, so the wearing on the battery could be absolutely normal (how many cycles?).
Btw I think is too soon to make assumptions on MacBook battery health.
Maybe it drops slightly faster to settle around 85-88% for a long time.
It is what happened to my wife's MacBook Air
I am seeing the same on my own 1.2, time will tell as it`s still a little early in the rMB`s lifecycle, although the current trend looks to be deeper than the MBP`s it may well stabilise and to some extents that is what CoconutBattery`s charts is currently indicating. Nor is significant depreciation of the batteries capacity observed by all.

Just wanted to follow up that at 40 cycles my design capacity is fluctuating somewhat, back up to 92.8% on coconut
Unfortunately this is exactly why these threads more often than not tend NOT to be helpful. They generate FUD. People start finding problems where they don't exist. They start repeating these non-problems in other threads. People start making purchasing decisions based on a "problem" that doesn't exist.
you are ahead of me. 247 and 84%. which i'm not happy about given, i'm only losing 15% of reported battery life already with less than a year on it
most likely when it goes under 80. i'm taking it to apple
Dunno. But I intend to find out. The battery health report fluctuates, though; right now it's reporting 84% health so I probably will need to wait a few months until it's consistently crappy. AppleCare has always been very, very good to me. I'm sure they will take care of this failing battery.
Absolutely. Apple are infallible and this problem simply doesn't exist. All the battery figures people have posted of their own rMB are a lie! And besides, a 10% loss off the advertised battery time within less than a year is entirely acceptable. After all who cares about a potential half an hour to an hour's worth of usage. And if you keep your MacBook plugged in all the time, you'll never experience this supposed "problem". Nevermind the whole point of the MacBook being a mobile, cord free computer.
Ten percent? I'm seeing 20% in six months. It's not great. But, Apple does take care of its problems.
As an extremely heavy portable user, whenever this thread is bumped back to the first page I report my numbers:
342 Load Cycles
4414 mAh Maximum Charge
83.4% Battery Health
All according to Coconut Battery.
Of note, it's been as low as 80.1% and has steadily crept up to 84% over the past month.
I received this rMB the first week it was released last year. I did purchase AppleCare.
