Guide to the battery lifecycle
Battery is an expendable item so its life gets shorter when
used for a long time. It is time to replace when the battery
run time is less than half of the figure when purchasing.
If you won’t use the battery for a long time, discharge
it first for keeping. This will guarantee longer life of the
battery.
Using Samsung Battery Manager
Battery Manager is a management program that
allows you to use the battery efficiently. You can select
the optimized power mode depending on the system
environment.
