One embodiment provides a method to store electrical energy in an electronic device, which has a central processing unit (CPU) to provide operating-system and application processing in the device. The method includes controlling, from the CPU of the electronic device, communication sent from the device and received at a wireless charger within communication range of the device. The method further includes computing, in the CPU of the electronic device, a set-point condition for wireless energy flow from the wireless charger to an energy-storage component of the device, and regulating the wireless energy flow based on the set-point condition.
