I'd like to see the Air-vs-Pro graph in terms of mAh instead of percentage of factory capacity. Better yet, in terms of expected running time on a full charge.

Re: The De-evolution of My Laptop Battery
#22I've only recently started collecting data for my Early 2011 MBP, but I'm starting to see a pretty steep decline. From 72% capacity down to 58% in a little over a month feels like I might be nearing the end of life for my battery.
date | capacity | loadcycles

#23This is why I prefer replaceable batteries. Ultrabooks look nice, but ultraportables are more practical in my opinion.
Re: The De-evolution of My Laptop Battery
#24Wow, this is an excellent article! Nice visualization of the battery life. I am quite nervous about the battery sealed inside my own new Macbook. Is it better to attempt to use the battery as much as possible in order to get a new one before the 3 year Applecare Warranty expires? Or to maniacally keep the machine plugged in if at all possible? Or simply not to care? The price of a replacement will be high, and I wond…
I believe Apple charges $199 for a battery replacement, which is definitely not cheap, but might be worth it if you were still happy with the rest of the machine. I'm not sure how long it takes them to do it, though. I'd expect they'd continue to offer that service for quite a few years to come.
As other posters have mentioned, it seems to me like the glued-in batteries don't rapidly decline like the old ones did. I don't have any numbers, though, just impressions.

#25anyone know how to do something similar on a windows laptop?
I have no experience with this kind of stuff for Windows, but I really hope somebody wiser than I can do it easily. I assume there must be an equivalent to cron in win8?

#26Is this guy really a developer? I can't imagine using a single 15" monitor to accomplish anything at a productive pace.
Single tasking is the new multitasking.

No true Scotsman would do such a thing.

imo very conscious decision on part of Apple (and PC makers) to provide short battery half lives, rather than spending more money to deal with the size and heat/cooling constraints of laptops, especially the thin lightweight variety.
not only saves them money short term, but helps push users to new versions before they really need to jump...

Apple batteries cost no more than competitors' batteries, and that includes getting them exchanged. Sure, it's annoying you can't do it yourself, but that's about the extent of the downside.
Of course you cannot get third party batteries … but surely no one would get those for laptops amyway. (Well, some batteries are not yet glued in, so those can easily be replaced. But i don't think getting third party batteries is very wise.)
Re: The De-evolution of My Laptop Battery
#30One other possibility; does the "battery health" metric actually mean the same thing it did four years ago? My 2012 MBA is showing 92% capacity, and seems to last about as long as it did when new. My 2007 MBP shows ~70% capacity, and lasts about an hour; it lasted about four hours when new. I'm not convinced it's that meaningful a metric.
