Abstract: This application relates to terminal devices, and discloses a method. In the method, a battery protection voltage parameter is determined based on battery usage data, where the battery protection voltage parameter is used to change an original voltage parameter corresponding to a battery level; a second mapping relationship between an actual battery level and a target battery level is determined based on the battery protection voltage parameter; and the target battery level is determined based on the second mapping relationship and the actual battery level of the battery. Alternatively, a correspondence between an actual battery voltage and a target battery level is determined based on the battery protection voltage parameter; and the target battery level is determined based on the correspondence and the actual battery voltage of the battery.

Abstract: This application discloses a charging method and an apparatus. An example apparatus (e.g., an electronic device) includes at least one processor, a wireless coil, and a battery. The at least one processor is configured to determine that a charging port is connected to a charging port. The at least one processor is further configured to, when a temperature of the battery is lower than a first temperature value, control the charging power supply to supply power to the wireless coil to cause the wireless coil to generate heat that increases the temperature of the battery. The at least one processor is further configured to, when the temperature of the battery is higher than a second temperature value, control the charging power supply to charge the battery, wherein the second temperature value is greater than or equal to the first temperature value.
