  • Patent number: 11036272
    Abstract: The present disclosure relates to a method applied to an electronic device with a screen. The screen displays a display interface. In one example method, a current value of a current sampling point is obtained. Based on the current value, whether power consumption of the electronic device meets a criterion is determined. The display interface is adjusted when the power consumption of the electronic device does not meet the criterion.

  • Publication number: 20190324086
    Abstract: Embodiments of this application disclose a battery leakage current check method, apparatus, and circuit, and relate to the battery field, so as to check for a leakage current inside a battery. The battery leakage current check method includes: when a power adapter supplies power to an electronic device, controlling the battery to stop supplying power to the electronic device; obtaining a voltage parameter and a duration parameter, where the voltage parameter is a difference between voltages of the battery at two different moments, and the duration parameter is duration between the two different moments; and determining, based on the voltage parameter and the duration parameter, whether a leakage parameter of the battery meets a preset condition. The embodiments of this application are applied to battery leakage current check.
