Battery Life — Continuous Playback Music Notes

The values shown in this topic are the approximate battery life when content is played continuously at the default settings. Even if the player is turned off for an extended period, a small amount of battery power is still consumed. Battery life may vary depending on volume settings, conditions of use and ambient temperature. The battery is consumed considerably when the screen is on. The battery life may become about 70% shorter when some of the sound quality settings are active.
