I've found the opposite. Before that computer bricked itself I noticed capacity was fading fast. Apparently apples threshold was if you are under 85% within a year of ownership you have a defective battery, according to the customer service agent I was chatting with. So they had me open up system profiler and we confirmed my battery was well within threshold for replacement, and they set me up with an appointment. I took it to the apple store and told them what the Apple customer service representative told me about the battery being defective. They ended up running a battery test using their internal tooling and surprise surprise, it turned out a different capacity number than system profiler said I had, and it happened to be just above the threshold for replacement. 1 year of use for full time work should not mean losing 15% of your battery capacity, but evidently according to apple this was in spec.
