The disclosure herein relates to a method and system for providing device accessory illumination (e.g., glowing, lighting-up, and/or other illumination) based on device-related information. In some implementations, illumination may be provided at a device case (of a device) that interfaces with a charging device based on a charge status of the device, communication information of the device, and/or application information of the device. As an example, an illumination status for the device case may be determined based on the charge status of the device, the communication information, and/or the application information. Illumination may then be provided at the device case based on the illumination status. The illumination status may, for instance, indicate an amount, a color, a pattern, a time feature, a location, and/or other characteristic.
