Ok it is official. New update 10.12.2 fixed my battery I am up back to 9-10 hrs of regular use. Before update idle power consumption was not going lower than 6W, after 10.12.2 it is now < 4W (60% brightness, ALS on). With ~50Wh battery, it translates easily way over 10 hrs (if you are not doing much apart from safari). To get 10 hrs MacBook must average 5W (second attachment) - I get 5.3 Watts Safari browsing, mail, Fantastical2, Bear, Snappy and more apps in background. HOW ABOUT YOU?
