Charging in the battery care mode
You can reduce deterioration of the battery by using the [Battery Care] mode. The battery duration is approximately 10 %
shorter in the [Battery Care] mode, as your Walkman stops charging at about 90 % of the full charge.
1. From the Home menu, select
2. Select [Common Settings] - [Battery Care] - [On].
Note
In the [Battery Care] mode, the first bar of the battery indicator will disappear somewhat more quickly than normal.
This is because your Walkman stops charging at about 90 % of the full charge, and is not a malfunction.
