US 12,308,672 B2 · Electronic device fast charging method, apparatus, and device

Abstract

A fast charging method for an electronic device is disclosed. The method includes obtaining, when the electronic device has a successful communication handshake with a USB host device using the USB interface, a corresponding charging data set of the electronic device under the charging current threshold by means of measurement according to a preset charging current threshold. The charging current threshold includes at least a first charging current threshold and a second charging current threshold. The charging data set includes at least a corresponding first charging voltage value and a corresponding first charging current value of the electronic device under the first charging current threshold, and a corresponding second charging voltage value and a corresponding second charging current value of the electronic device under the second charging current threshold. The method further includes determining, according to the charging data set, a maximum charging current value.

Dependent claims

An apparatus, comprising:

a touch display screen;
a memory configured to store instructions;
and
one or more processors coupled to the touch display screen and the memory, wherein the one or more processors are configured to execute the instructions stored in the memory to cause the apparatus to:
display a first graphical user interface (GUI) for selecting a charging mode, wherein the charging mode comprises a fast charging mode and a normal charging mode, and wherein the fast charging mode is associated with a first charging current value, the normal charging mode is associated with a second charging current value, and the first charging current value is greater than the second charging current value;
receive a first operation for selecting the fast charging mode;
be charged by another apparatus in the fast charging mode via the first charging current value in response to the first operation;
and
switch the first charging current value to a third charging current value when a temperature data value of the apparatus is greater than a first temperature threshold, wherein the first charging current value is greater than the third charging current value and the third charging current value is non-zero.
