Abstract

The invention discloses a charging method and an electronic device. The charging method comprises the following steps of determining that a current charging mode of a battery of the electronic device is a first charging mode at a current moment; acquiring M charging voltages of the battery within a preset time frame before the current moment, wherein arbitrary one of the M charging voltages is a charging voltage corresponding to a moment when the electronic device is separated from a power supply; determining N charging voltages of which the voltage values are lower than a preset voltage value from the M charging voltages, wherein N is an integer less than or equal to M; and controlling the current charging mode to be adjusted to a second charging mode from the first charging mode if N is greater than a preset value, wherein the second charging mode is a mode that the fully-charged voltage of the battery is smaller than the voltage of a battery core. With the technical scheme provided by the embodiment of the invention, the technical problem of relatively single condition existing in the switching charging mode of the electronic device in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charging method and electronic equipment. Background technique [0002] With the continuous development of science and technology, various electronic devices, such as smart phones, tablet computers and notebook computers, are constantly updated. [0003] For electronic equipment, batteries are an indispensable part of electronic equipment. With the continuous updating of electronic equipment, the requirements for battery capacity and cycle life of electronic equipment are also getting higher and higher. In the prior art, in order to extend The cycle life of the battery, after the battery is used for a certain period or stored in a high-voltage state for more than a certain period of time, the control battery is switched from RT (Runtimemode, longest battery life mode) mode to LS (Lifespanmode, longest lifespan mode) mode, Its control conditions are relatively simple and ca...
