Abstract
A charging method includes: obtaining a first temperature at a preset position on an electronic device when constant-current charging is performed on a battery of the electronic device at a first constant current; in response to that the first temperature exceeds a preset first temperature threshold, obtaining a first voltage currently present at a designated position in the electronic device, and obtaining a second constant current preset in the electronic device; performing first constant-voltage charging on the battery at the first voltage until a charging current during the first constant-voltage charging is changed to the second constant current; and performing the constant-current charging on the battery at the second constant current.
