Abstract
Embodiments of the present disclosure provide a charging method, a charging device and a terminal. The charging method includes: when detecting that a battery is charged with a trickle current, acquiring a voltage of the battery; determining a preset voltage range to which the voltage belongs; acquiring a charging current corresponding to the preset voltage range; and charging the battery according to the charging current. During a process that the battery is charged with the trickle current, the battery may be charged with a different charging current when the voltage of the battery belongs to a different voltage range, thereby improving the flexibility of a trickle current charge phase.
