A reproduction apparatus includes a reproduction unit that reproduces digital data selected by a user; a prediction unit that predicts a reproducible time based on remaining power of a battery and a determination unit that determines whether the digital data selected by the user can be reproduced to the end or not based on the reproducible time, wherein when the determination unit determines that the selected digital data can be reproduced to the end, the reproduction apparatus causes the reproduction unit to reproduce the selected digital data and when the determination unit determines that the selected digital data cannot be reproduced to the end, the reproduction apparatus warns that the digital data cannot be reproduced to the end.
