Well, it maybe small sample, but that doesn't change the fact that there may indeed by some intrinsic issue. So it is not nonsense like you said.
Of course it is you have made a blanket statement about a product with no real evidence to back it up, there could be a problem means nothing. There could be a problem with almost anything.
As I explained this is a risk with any lithium ion battery and if you asked this question about any generation of any laptop computer you would get a similar number of results. Go on go and ask on dells forums, or microsofts or Lenovo or ask the same question on here for a 2013 MacBook pro or a 2014 MacBook air etc etc etc.
Its an underlying issue with the technology which we accept because they are currently the best battery option for a portable device that simple.
