This is a battery spec, so you would only use it if it is on a mobile device. One can use User agent string to determine if you are on a mobile device. Otherwise, might consider to change this attribute to a “state” attribute of enumerated type of (charging, discharging,undefined).

The attribute MUST be set to false if the battery is discharging, and set to true if the battery is charging. If the battery status cannot be determined, the implementation should raise an error or an undefined state. Absolutely not. The average case is that I'm on a desktop. We do *not* want average cases to trigger exceptions. Nor do we want them not to work. --------------------------------------------------------------------- This transmission (including any attachments) may contain confidential information, privileged material (including material protected by the solicitor-client or other applicable privileges), or constitute non-public information.
