    摘要： A method for determining a battery capacity, includes: acquiring a first inflection voltage, a first inflection electric power, a second inflection voltage, and a second inflection electric power of the battery, charging the battery and recording a first charging profile of the battery; determining a target inflection point of the battery according to the first charging profile; detecting the electric power until the charging is completed, acquiring a first charged electric power of the battery when the battery is charged to a first inflection point, and acquiring a second charged electric power of the battery when the charging is completed; and when the target inflection point includes the first inflection point, calculating a current capacity of the battery according to the first inflection electric power, the first charged electric power, and the second charged electric power. The first inflection voltage is greater than the second inflection voltage.

    摘要： A glitter module and an electronic product are provided. The glitter module includes a base material and a reflective graphic located on a surface of the base material. The reflective graphic includes multiple first-level regions. Each first-level region has multiple second-level regions. The second-level region is provided with a plurality of strip-shaped grooves. Each first-level region has a specified direction. An angle between an extension direction of a strip-shaped groove of a plurality of second-level regions in a same first-level region and a specified direction of a corresponding first-level region ranges from −20° to 20°. Along a preset direction of the reflective graphic, angles between specified directions of the plurality of first-level regions and the preset direction are in a gradient change relationship.
