100% Switches off
Once the battery is fully charged, the
battery charging state indicator
switches off to conserve energy.
If the battery has not been used for a
long time and has run down, it will
switch to safe mode. As a result, the
battery charging state indicator will
only respond after approximately
30–60 minutes.
