Managing power-consuming resources on a first computing device by time-based and condition-based scheduling of data delivery from a plurality of second computing devices. A scheduler executing on the first computing device has knowledge of recurrent schedules for activation by the second computing devices. The first computing device determines availability of the power-consuming resources and adjusts an activation time for the schedules to use the power-consuming resources when the resources are available. Managing the schedules associated with the second computing devices preserves battery life of the first computing device.
