Claim Text:
1. A method, comprising: receiving, by a first device, a user's selection of a charging criterion for balancing stored charges in the first device's own battery and in a second device's rechargeable battery, and a use case characterizing a use of the first and second devices; monitoring, by the first device, a present level of stored battery charge in the second device's rechargeable battery and a present level of stored battery charge in the first device's own battery; accessing, by the first device, battery characteristics data for the battery of the second device, and a profile of power consumption of both the first and second devices for the use case selected by the user characterizing the use of the first and second devices; determining, by the first device, from the profile of power consumption of both the first and second devices for the use case selected by the user characterizing the use of the first and second devices, charge consumption of the first device for selected use case and charge consumption of the second device for selected use case; determining, by the first device, whether recharging of either the first or the second device's rechargeable battery is required, based on whether the stored battery charges in the first device and in the second device are sufficient to satisfy the user's selected charging criterion for the selected use case; computing, by the first device, an amount of charging required for either the first or the second device's rechargeable battery, in order to satisfy the user's selected charging criterion for balancing stored charges in the first device's own battery and in the second device's rechargeable battery for the profile of power consumption of both the first and second devices for the selected use case; and controlling, by the first device, power flow between the first and second devices, by transmitting, by the first device, power provided by the first device's own battery, to the second device, for charging the second device's rechargeable battery until the present level of stored battery charge in the second device's rechargeable battery reaches the computed amount of charging required, if charging of the second device's rechargeable battery is determined to be required, and by receiving power, by the first device, from the second device, provided by the second device's rechargeable battery, for charging the first device's rechargeable battery until the present level of stored battery charge in the first device's rechargeable battery reaches the computed amount of charging required, if charging of the first device's rechargeable battery is determined to be required.
