function in the LG Smart
Assistant. You can limit
the battery charge to 80 %
of the maximum charging
capacity to increase the
battery lifespan.

use the battery for a while
before charging it rather
than keeping the battery
completely charged.
If you don’t use the product
for a long time with the
battery completely charged,
the battery lifespan may
decrease.
