    Abstract: A stand for a cleaner is capable of holding and charging selectively a cleaner body or a battery. The stand for a cleaner includes a first charging terminal configured to be electrically connected to a cleaner body, a second charging terminal configured to be electrically connected to a battery, and a battery guide configured to guide the battery. The battery guide guides the cleaner body to be connected to the first charging terminal when the battery is mounted to the cleaner body, and is configured to guide the battery to be connected to the second charging terminal when the battery is separated from the cleaner body.

    Abstract: An electronic device and method for providing information for stress relief are disclosed. The electronic device includes a user interface, at least one sensor, at least one processor operatively connected to the user interface and the at least one sensor, and a memory operatively connected to the at least one processor. The memory stores instructions to, when executed, cause the at least one processor to collect stress-related information through at least a part of the at least one sensor, identify contextual information of a user when stress calculated based on the collected stress-related information satisfies a designated condition, and guide at least one of a plurality of stress relief methods through the user interface at least based on the identified contextual information.
