User activity on a mobile device is monitored and collected, and a resource usage model is constructed. The resource usage model describes a set of contexts in which the mobile device, and is the basis for determining a first exhaustion point for a resource. Based on the monitored activity, a prediction of a second exhaustion point for the resource time is made. If the second exhaustion point is prior to the first exhaustion point, usage of the resource is reduced.
