Abstract:
A device, system, and method enhances battery performance on a user equipment. The user equipment includes a rechargeable battery, a charging circuit, and a processor. The charging circuit controls a recharging operation for the rechargeable battery. The processor determines an activity condition and a charge condition, the activity condition based on a foreground activity running on the user equipment, the charge condition based on a charge capacity of the rechargeable battery being above a capacity threshold. The processor selects a first charging rate at which the charging circuit recharges the rechargeable battery when at least one of the activity condition and the charge condition is absent. The processor selects a second charging rate when the activity condition and the charge condition are present, the second charging rate being less than the first charging rate.
