The internal battery is a consumable part.
Each time the internal battery is recharged,
the battery usage time per one charge
gradually decreases.
･
When the battery usage time per one charge
becomes about half of that at the time of
purchased, replacing the internal battery is
recommended because the internal battery is
near the end of life.

Watching 1Seg etc. for a long time while
charging may shorten the lifetime of the
