Abstract: Methods, systems, and devices for wireless communications are described. A device may identify modes from a set of modes in which at least one modem functional block of a set of modem functional blocks of a chipset operates during a portion of a time interval. Each modem functional block may include a set of units classified to have a power response that satisfies a power trend metric for at least one mode. The device may select power calculation equations from a set of power calculation equations based on the set of multiple modes, calculate an power consumption level for the chipset for the time interval based on the selected power calculation equations and a proportion of the time interval a respective multiple modem functional block of the set of modem functional blocks operates in a respective mode of the set of multiple modes.
