It is worth reading through the rationale behind MIT’s decision. In particular the announcement you linked to talks about how at MIT passing a rigorous calculus programme is critical to progressing. So the SAT, with its high mathematics content is useful to determine who is well prepared enough to be successful in the MIT programme.

To me this seems logical - the university is testing for preparedness for their own programme which includes a must pass to progress exam. As far as I can see from the argument they are not saying that their decision should be universally applied.

As one of those who excel with assignments and research type work, but struggle in an examination environment, it would be great if MIT had an alternate path to prove capability and subject mastery, but it is their prerogative to structure it this way.

Very interesting story and I have a data point to add: I bought my iPhone 6 new in 2014 and as of about two months ago the battery (which was at more than 750 cycles - Apple rates it for about 500) was getting really flakey. The reported capacity of the battery started varying between 45% of its rating and 85% with random power offs becoming common below 10%. So last weekend I finally bit the bullet and put a new battery in - fiddly but doable in about 30 mins. I then reset the phone and left it to fully charge overnight.

Since changing the battery the iPhone has been subjectively faster to launch apps and display information. So this report that Apple may have something in iOS that compensates for a failing battery doesnâ(TM)t seem implausible.

Though I would have thought that a better thing (or perhaps as well as) would be if Apple gave the user an alert once 500 cycles exceeded advising them that the battery was wearing out and linking them to the official Apple page for getting it changed.
