CHARGING METHOD, CHARGING APPARATUS, AND ELECTRONIC DEVICE

Provided are a charging method, a charging apparatus, and an electronic device. The method includes: collecting a charging current and a battery voltage of the to-be-charged device in real time; according to the charging current and the battery voltage collected during a constant-current charging phase, increasing a charging voltage according to a preset step voltage and controlling an increasing speed of the charging voltage; according to the charging current and the battery voltage collected during a constant-voltage charging phase, decreasing the charging voltage according to the preset step voltage; and charging the to-be-charged device according to the charging voltage and the charging current. With this solution, high-efficiency charging is implemented through the reduction of an energy loss.
