Concerns about the autonomy of New MacBook Pro Batteries were the subject of an article here a few weeks ago. Shortly thereafter, Apple made macOS Sierra 10.12.2 available to all users, and it brought a rather controversial change: it removed the estimated battery usage time from the operating system menu bar.
It doesn't take any genius to link something else, especially since OS X macOS has had that estimate forever. To further contribute to the "coincidence", Apple last week opened job openings in search of battery experts.
The problem is so serious that for the first time in history Consumer Reports * no * recommends buying new MBPs precisely because of these inconsistencies in the batteries. The three models tested by the 13-inch Touchless and 15-inch Touch Bar and 15-inch Touch Bar have not passed their tests in this regard, with longevities ranging from 3.75 to 19.5 (!) Hours, while the expectation is that between trials the variation is not more than 5%. Apple's official promise of “up to 10 hours” of autonomy is worth remembering.
Perhaps one of the most widespread proof that there are optimizations to be made (on the software side, which is reassuring) that CR has achieved more battery life with the new MBPs running tests on Google Chrome instead of Safari. This makes absolutely no sense at all.
Apple, move it.
