MacBook Battery time remaining

Apple removed the “battery time remaining” indicator from the battery status menu in the latest version 10.12.2 of macOS. Apparently it wasn’t accurate.

Did you know that MacBook batteries have a dedicated chip that keeps track of how much energy goes in and out of the battery during all times? For example, the 13″ MacBook Pro from 2015 uses a BQ20Z451 “battery fuel gauge chip” from Texas Instruments.
