The at least one processor may be configured to execute the instructions to: monitor a usage pattern of the battery while the electronic device operates in a first power management state; acquire, based on determining that the usage pattern of the battery is different from a reference pattern derived from a model, information on a location in which the battery is estimated to be charged and information on a time at which the battery is estimated to be charged using the model; and switch, partially based on the information on the location and the information on the time, the first power management state to a second power management state based on a second maximum driving frequency lower than the first maximum driving frequency.

A wireless mobile device in a public communication network receives network-initiated signaling or messaging, while operating in a battery-conserving mode, or modes that, keep(s) minimal baseband processing functions awake. The baseband processing functions process incoming signaling or data in a received message to determine whether to act further on information in the incoming message by enabling additional processing capability in the mobile device. The mobile device may have permanent template criteria values, either coded in firmware or implemented in hardware, or temporary template criteria values, stored in RAM or processor registers, that are compared to values of an incoming message or datagram from the mobile network to determine whether to perform additional actions, such as awakening an application processor. Multiple templates may co-exist to allow different incoming datagrams to cause the device to take some additional action, respond, or even ignore information in an incoming datagram or message.

A system of mobile devices that reduces the transmission strength of outgoing signals originating from a handheld device, and sends such signals to a second device, situated near or on a lower-body location, where the signals may be amplified to the current permitted maximum transmission strength vis-a-vis the brain (SAR), or above that level to the greater maximum strength permitted in the areas of, e.g., the feet and ankles, where the signal is then sent outward. The devices divert radio frequency (RF) radiation exposure downward toward the lower extremities. The intelligence and power of the devices may be split between two or more devices, resulting in longer use time, deeper and more complex computing capability, and fewer disruptions due to power. In addition, a benefit in one or more embodiments is better, more reliable reception, due to the use of two or more coordinated receiving antennas.

A hydrant apparatus may be employed to monitor a water distribution system, and may include a sensor, a processor, and a local clock source. The apparatus may wake from a low power mode to a sensing mode, receive the sensor data, associate the sensor data with a first local clock time, and return the apparatus to the low power mode from the sensing mode. The apparatus may subsequently wake to an operational mode, determine a second local clock time subsequent to the first local clock time, associate an external clock time with the second local clock time, determine an offset for the received sensor data based on the first local clock time and the association between the second local clock time and the external clock time, and transmit the sensor data and the offset to an external monitoring system.
