Note: Continuous playback time was tested after playback by locking the hold switch and putting the LCD to sleep, and then leaving it untouched. This was done to confirm that this is the average performance of the purchased battery group, eliminating human operation. This is not based on actual use. In reality, the playback time will be considerably shorter due to power consumption by the LCD each time you operate it, such as by changing songs or adjusting the volume. In that case, it seems that the playback time will be longer if you minimize the LCD brightness. Note: All units are initialized with iTunes, after songs are loaded, operation is confirmed, and only normal units are finally initialized and shipped. This is a listing for a used, working unit only. Battery replaced with a new one (2025/12/7) LCD has not been replaced. There is some age-related degradation (yellowing). It displays normally.
