The battery life is short.
If your Walkman is used in an environment where the temperature is below 5 °C (41 ºF), the battery life becomes
shorter due to characteristics of the battery. This is not a malfunction.
Charge the battery until it is full.
The battery life can be extended by using wired headphones instead of Bluetooth audio devices.
More battery power is consumed when the Bluetooth function is used.
More battery power is consumed when the noise canceling function is used.
When [Battery Care] is set to [On], the maximum recharge capacity is limited to about 90 %, resulting in the first bar
of the battery indication disappearing quickly.
You can preserve the battery life and get more use from each charge by changing your Walkman settings and
managing the power appropriately.
Depending on the environment in which your Walkman is used, the battery may deteriorate if it is not used for over a
year. Contact your nearest Sony dealer.
If the usable battery life is half that when new even after sufficiently charging the battery, your battery may have
deteriorated. Contact your nearest Sony dealer.
