76 Chapter 3 Using Your MacBook Pro
If the battery icon in the Finder menu bar is set to show the percentage of charge,
sometimes the battery won’t show a full 100 percent charge when the power adapter
is attached. This is normal behavior; battery life is saved when charging is not
continuously cycled on and off when the battery’s charge capacity is between 95 and
100 percent. When the battery level eventually drops below 95 percent, it will charge
all the way to 100 percent.
