Abstract
A portable device, for example an offender monitor, can utilize a GPS receiver or other location detector to provide locational information for the device. The portable device can communicate over a cellular network, for example using a radio to transmit location readings over the network. The location detector and the radio can draw power from an onboard battery. The portable device can operate in at least two modes. When charge of the battery drops below a threshold, the device can switch from the first mode of operation to the second mode to conserve power and avoid fully depleting the battery.
