Battery Time shows the remaining time your MacBook can run on its battery in the menu bar.
The remaining time varies depending on usage, so you can see when your MacBook suddenly consumes more power.
E.g. when starting to watch an HD video after surfing the web, the time decreases after a few seconds.
When charging, Battery Time shows the remaining time to charge the battery up to 100%.
