Tips to maximize the battery life (NW-A100/NW-ZX500 series)

    IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.

    The Walkman® consumes battery even when in playback standby, so the battery life will be shorter if the player is in standby for a long time. If multiple applications are running, the battery consumption will also increase and the usage time will be shortened. Battery life also varies depending on usage conditions, settings, and temperature.

    This article shows ways to reduce battery consumption and increase battery life.

    Settings to maximize the battery life

    Battery Saver

    Activating the Battery Saver function can help to reduce battery consumption when the battery level is low. n addition, you can set the Battery Saver function to activate at a desired remaining battery level.

    1. Swipe the home screen upwards, then select Settings.

    2. Select Battery.

    3. Select Battery Saver.

    4. Set Turn on automatically to On.

      Note: If you select TURN ON NOW, the Battery Saver function will be activated regardless of the remaining battery level.

    5. Set the AT xx% value to the desired percentage.

      Note: The Battery Saver function will be activated when the remaining battery level reaches the percentage value set.

    Other settings

    You can reduce battery consumption by changing how you use the player. Try the following suggestions to increase battery life:

    Note: When used in a cold temperature environment, the battery life will be shorter.

    In cold environments, chemical reactions become weak and electrical energy lowers. The battery cannot be fully charged in a cold environment. Even if you fully charge the battery in a warmer environment, the battery life shortens when you use it in a cold environment. (If you return to a warm environment, the battery life returns to normal)

    About the battery life

    Lithium-ion rechargeable batteries gradually decrease in charging capacity and duration depending on the number of charge/discharge cycles and the period of use.

    To reduce deterioration and extend the battery life:

    • Stopping the battery charging before reaching full (Don't charge up to 100%) can help reduce the deterioration of the battery.
    • If the rechargeable battery is stored for a long time in a totally empty or fully charged condition, the battery tends to deteriorate. In order to prevent deterioration, charge the battery to about 50% once every six months to one year.

    Estimated replacement time:

    • The number of charge/discharge cycles, usage period, and conditions can all affect the capacity of the battery and reduce the battery life.
    • If the battery life is reduced to half as what is mentioned in the manual even after the fully charged, the battery may need to be replaced.
