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.
