MacBook shuts down with 60% battery My laptop shuts off with 50%-60% battery levels without saying anything - just dims the screen go off. If I try to turn it on again, it shows me the big "low battery level" indication and won't start unless i plug it in. Is it normal?

MacBook Pro (Retina, 15-inch, Early 2013)

macOS Sierra 10.12.3
This is not normal, shutdown the laptop and the press the Power Button and hold down Command + Alt/Option + P + R. Hold these buttons for around 20 seconds. This might fix the issue. 

I had the same issue on a MacBookPro10,1 (15" Retina, Mid 2012) and reseting the NVRAM fixed it for me.

If that does not fix it, it might be a worth a trip to the Apple Store.
