Security is enhanced for a user of a mobile device by monitoring and controlling resource usage. Usage information associated with a mobile device is collected. The collected information is used to build a usage model for a user of the mobile device that describes a set of contexts in which the mobile device is used. User activity on the device is monitored and the model is consulted to determine a first time after which it will be acceptable for a battery of the mobile device to fall below a threshold charge level. Based on the monitored activity, a prediction of a second time is made for when the battery will fall below the threshold charge level. If the second time is before or a predetermined amount of time before the first time, usage of the battery is reduced, else, usage of the battery is not reduced.
