INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Various embodiments of the invention provide methods, systems, and computer-program products for charging a battery of a first mobile device from a battery of a second mobile device. In particular embodiments, a request is received identifying an amount of charge to provide from the battery of the second device to the battery of the first device. Accordingly, a determination is made as to whether the amount of charge requested is likely to result in a battery charge of the second device dropping below a threshold value before the battery of the device is recharged based on historical battery charge usage data of the device over a past period of time. If the amount of charge is not likely to result in the battery charge dropping below the threshold value, then the battery of the first device is charged with the amount of charge from the battery of the second device. ## Claims ### Claim 1 A method for regulating current battery usage of a mobile device, the method comprising the steps of: monitoring the mobile device by a computer-program application residing in the mobile device for a triggering event, the triggering event comprising an activity beginning that requires power to be provided from a battery of the mobile device to function;
