Described are apparatus, systems, and methods that are operable to conserve battery power of a wearable device by monitoring a state of the user wearing the wearable device and adjusting power state of one or more components of the device based on the determined user state and/or altering a wireless transmission of sensor data collected by the wearable device from the wearable device to a portable device associated with the user. For example, if it is determined that the user is in a sleep state, the wireless connection between the wearable device and the portable device may be terminated, the wireless transmitter and the processor transitioned to a low power state, and sensor data stored in a buffer memory of the wearable device until a defined period of time before the user exits the sleep state and/or upon satisfaction of a buffer usage threshold.

Devices, systems, and methods are provided for gesture-based selections of devices. A method may include receiving, by at least one processor of a first device, an input associated with causing a second device to perform an action. The method may include identifying motion data associated with the first device. The method may include determining, based on the motion data, a gesture associated with the first device. The method may include receiving an indicator from the second device and determining, based on the indicator, that the gesture is associated with selecting the second device to perform the action. The method may include sending a command to the second device, the command associated with causing the second device to perform the action.
