The charging indicator flashes in red during wireless charging (WF-1000XM4).

    IMPORTANT: This article applies only to specific products and/or operating systems. Check the Applicable Products and Categories section of this article before starting these steps.

    When the wireless charging pad becomes too hot due to charging or ambient temperature, the indicator of the charging case repeatedly flashes twice in red. This means the temperature inside the charging case is too high and that charging has stopped to protect the battery. When this happens, remove the charging case from the wireless charging pad, let it cool at room temperature, and then start charging again.

    Note when using the wireless charging pad:

    • Charging may slow down or stop, or the charging case may easily become hot if the charging case becomes misaligned with the wireless charging pad. For details on how to set the charging case properly on the charging pad, refer to the manual of the charging pad.
    • When charging, remove anything attached to the charging case, such as covers. Depending on the material or thickness of the cover, or due to foreign objects caught between the charging case and the cover, charging may not be performed properly, resulting in fires, burns, or injuries.
