MacBook battery wear

FWIW my Full Charge Capacity is 4728 mAh after 257 cycles.
I have Applecare so not worrying about it until shortly before it expires.

Should have added, it is a 2016 MacBook, manufactured date 16th May 2016. Battery manufacture date 6th April 2016.

My Macbook from 2015 has 3943 mAh after 517 cycles so I think that is normal. I use both my MB and MBP without the charger daily, both home and on the run so I use alot of cycles.
It all depends on things like how much you run it without charger, on what kind of surface you have the computer on, temperature in the air, how hot you run the computer and other factors.

2015 (April) rMB: 4050mAh, 507 cycles. 78-80% health
The first 2 years (475 cycles) mostly on battery. Health was often below 80%. Last couple of months more on charger or RAVpower battery with usb-c PD.
Looks like the battery is more stable now and diminishing slower. Still holding 6 hours of light use (60% brightness)
No Applecare. The battery might last longer than 3 years the way I use it now. And a new battery might be cheaper than Applecare?
So according your stats, the 2016 (and 2017?) models are more or less like the 2015 then.

I think it is the same battery in all of three gens of the Macbooks, can't find any info. The newer processors and components are more efficient and do not use as much power so they may last a little longer for every generation.
Looking at our figures they look like the same so that is my guess.

Not so sure. I read somewhere in another thread some time ago that the original max of the 2016 model is closer to 5500mAh. The 2015 model is about 5300mAh. I don't know about the 2017 model.
The new (replaced) battery in the 2015 model had 5300mAh again. This was after the 2016 model was released.
So I assume there is some (small) difference in the respective models.
Here's my 2008 MacBook5,1 (aluminum unibody 13"). Not too bad, given the age and number of cycles. My 2009 MacBookPro5,5 hasn't fared quite as well though.

I have a 2016 model, purchased in the spring of '16, with 181 cycle count and it just started giving a Service Battery warning. No Apple Care, and the list price of battery replacement is $199. The Macbook has never been exposed to temperature extremes or charged on any other than the stock charger, this is obviously a manufacturing defect. Windows 8 drove me to the Apple world a few years ago, looks like I'll be headed back.
Search for ”mac service battery warning” on Google and try those fixes. It sounds like the SMC or something.
sorry to revive an old thread but how were you using it? did you keep it plugged it all the time?
It was a mix, I typically didn’t plug it up to charge if it was in the 80-90% range, but if it did need charging it might stay plugged up overnight.
what happens if the keyboard needs replacing under the 4year warranty period? Does that mean a new battery also, as is the case with MBPs, where everything is just glued together.
I've seen a lot of threads that these terraced battery design and the new chemistry that apple introduced w/ the 12" mb led to accelerated degradation in battery capacities. I have a 7-year-old 2012 rmbp 15" that has 200 cycles and is sitting on 91% capacity as I write this. I don't think these newer batteries on the current gen mb, mba and mbp last as long as the last gens.
I really don't know what changed but this degradation in battery quality over the years is really putting me off in buying another mb, even though I'm personally a fan of mb designs.

The fact I believe is Apple want us to replace our machines more often, like we do with iPads etc. So squeezing longevity out of the battery usability lifetime, is not really a priority any more.
