Charging time

USB-based charging

Approx. 3 hours (full charge), Approx.1.5 hours (approx. 80 %)

Battery life (continuous playback)

By setting as follows, a longer battery life can be expected.

The times below are approximated when “New Song Pop Up”, “Clear Stereo” , “DSEE (Sound Enhancer)”, “Dynamic Normalizer”, “Equalizer” and “VPT(Surround)” are deactivated, and “Screensaver” is set to “Blank.”

Furthermore, for videos, the time approximated when the brightness of the screen is set to “3,” or when “Sound Quality Mode” is set to “Normal Mode”.

The time below may differ depending on ambient temperature or the status of use. Battery life may be shortened by the radio waves generated by ambient Bluetooth devices or wireless LAN devices, or by the communication distance between the player and the communicating device.
