1. A method comprising:
determining, by a first computing device and via ultra-wideband ranging, that the first computing device is proximate to a second computing device paired with the first computing device;
determining, by the first computing device, that the second computing device is able to perform ultra-wideband ranging with a particular set of one or more devices;
in response to determining that the first computing device is proximate to the second computing device and that the second computing device is able to perform ultra-wideband ranging with the particular set of one or more devices, setting, by the first computing device, an ultra-wideband component of the first computing device to a power-saving mode;
after setting the ultra-wideband component to the power-saving mode, determining, by the first computing device and via ultra-wideband ranging, that the first computing device is still proximate to the second computing device and that the second computing device is not able to perform ultra-wideband ranging with the particular set of one or more devices; and
in response to determining that the second computing device is not able to perform ultra-wideband ranging with the particular set of one or more devices, setting, by the first computing device, the ultra-wideband component to a normal operating mode for performing ultra-wideband ranging.
