Macbook 2015 Battery Capacity degrading fast ?

Note to those with rapidly diminishing battery capacity; Have your rMB checked by Apple as the Genius can run extended diagnostics. Some members of the forum have found that there was issue with the Logic Board (resistors), subsequently Apple replaced both the battery & Logic Board under warranty.
At very least you should ensure the issue is documented in Apple`s system, those in the EU and UK have strong consumer protection use it to your advantage...

Pass too many variables, ambient & operating temperature, discharge & charge rate, depth of discharge etc. It either will to it won't, bear in mind the battery is a consumable item, or are they vastly expensive.

12 cycle now and my battery health show 92%
what the problem actually on this macbook

Mine looks very similar to yours. Same manufacture date.
Have been down to 88% just for a few days ago.
It looks like as if it is stable at some point for some time. Then drops 5-6% really fast. Crawling up again 2-3% shortly after and then staying there for a few weeks before the whole thing repeats itself.
I don't think this is enough for a replacement at all. It might stabilize after some time (one year???).
I've heard that if the health is below 80% after 1000cycles or 2 years you can get a replacement. In Norway at least.
Yes, replaced my Macbook Air 2010 battery last October (2014) here in Norway. I like the consumer laws here, but sometimes you have to force them through. A functional knowledge of consumer rights isn't always the true motivation behind working in retail
I find interesting how 2 people who claim their battery is good...never post actual picture of their battery.
mine is at 82%, very soon I will be going to Apple store to get a new replacement. this is just pathetic

Seriously
I use the Notebook on battery when needed, when there is mains available I use that, would you like to see the battery spec`s for my 13" & 15" Retina`s they are also still in the 90`s. As stated previously those with rapidly diminishing battery capacity should have your rMB checked by Apple as the Genius can run extended diagnostics. Some members of the forum have found that there was issue with the Logic Board (resistors), subsequently Apple replaced both the battery & Logic Board under warranty.
At very least you should ensure the issue is documented in Apple`s system, those in the EU and UK have strong consumer protection use it to your advantage...
n.b. If you search you will find I have posted far more detailed information on my rMB`s battery usage.

However, when you said your battery was much the same as Alexrat1996, that was in no way true, I'm pleased to see.
Alexrat, are you talking about a MacBook Pro or something?
Sometimes one should apply common sense, as in his/her Mac`s battery is not depreciating excessively, that was the concern, the specifications are irrelevant...
FWIW it`s a 13" my own 13" rMBP is currently at 97.4%

That app is spot on. It shows the exact same reading as OS X system report every time. If there is any issue here, it is not Coconut Battery.
AT 90% of the original max value they won't replace it.
Mine has been going from 94% down to 89% and then sometimes up a bit. 150 cycles. Around 6 months old. Now resting at 89,8%. Can I get it replaced?
If it drops below 80-85% during the warranty period they could ....
