Charging does not start, or left and right earbuds stop charging at different levels using Battery Care (WF-1000XM6)

    Battery Care is a feature that limits the maximum charge level to help extend the battery’s lifespan.

    The following behavior is normal when Battery Care is enabled.

    • When Battery Care is enabled, charging may not start depending on the remaining battery charge, or may stop before the battery reaches 100%. The exact charge level at which charging stops can vary depending on ambient temperature and usage conditions.
    • After using the headphones for a while and the remaining battery drops below a certain level, charging will resume when the headphones are placed back into the charging case.
    • Additionally, because the left and right earbuds may consume power at different rates, they may also stop charging at different battery levels. As a result, one earbud may resume charging while the other does not.

    If you want the earbuds to charge to 100%, turn off Battery Care in the Sony | Sound Connect app first, and then place them in the charging case.

    How to turn off Battery Care

    1. Open the Sony | Sound Connect app, and select Device settings.
    2. Tap Power/Battery.
    3. Tap Battery Care, and set the Battery Care setting to OFF.

    Note: If you turn off the Battery Care and then turn it back on again, charging will stop until the remaining battery charge drops below a certain level.
