Regarding battery life TSMC vs. Samsung chips, the link given in the other article (http://browser.primatelabs.com/battery3/search?dir=desc&page...) seems quite conclusive -- sorting by score, ratings in both 6s+ and 6s are clearly dominated by TSMC (motherboards without an "m").
This is of course as Apple states a fairly narrow and not necessarily representative test; but if I ever decide to upgrade from my 5s to 6s, I think I know which one I would want :)
Now, I'm not quite sure upgrade would be a good idea -- 5s seems snappy enough, and size does bother me quite a bit. On the other hand, I just noticed claims improved water resistance -- http://www.engadget.com/2015/10/02/iphone-6s-waterproof -- that make me seriously consider getting one...
