Most charge indicators report battery status as both a percentage and as the number of minutes of
charge remaining:
● The percentage indicates the approximate amount of charge remaining in the battery.
● The time indicates the approximate running time remaining on the battery if the battery continues
to provide power at the current level. For example, the time remaining will decrease when a DVD
is playing and will increase when a DVD stops playing.
When a battery is charging, a lightning bolt icon may be superimposed over the battery icon on the
Power Meter screen.
