I have a new 2016 Retina MB 12" and it has a lot of weird issues with battery. First off, when I plug in the charge, it's not recognized. When I click on the battery icon in the toolbar, sometime it'll say "not charging" Sometimes it'll still claim to be on "battery power" when it's plugged in. It does seem to charge fine, though. Second, when in use, the battery percentage reads 100% and doesn't go down. BUT.. when I activate the screen saver or lock the screen, the actual lower battery percentage will show in the toolbar. Then when I log back in, it's back to 100% Sounds like classic SMC stuff - I went through the reset procedure (shut down, unplugged, left shift-ctl-opt + power for 10 seconds, then restarted) but it hasn't fixed anything. Any help?
