5. The wearable apparatus of claim 1 , wherein: the command further comprises a command to operate in a medium-power mode, and the medium-power mode has at least one of a range of communication or a transmission rate between those of the low-power mode and the high-power mode.

6. The wearable apparatus of claim 5 , wherein the at least one processor selects a sampling rate for the at least one sensor based on the command to operate in the low-power mode, the medium-power mode, or the high-power mode.

7. The wearable apparatus of claim 1 , wherein receiving, from the at least one sensor, indicator of activity of the user comprises extrapolating an activity score based on measurements of the at least one sensor.

8. The wearable apparatus of claim 1 , wherein the operations further comprise selecting a power mode for the at least one sensor based on a power mode selected for the at least one transmitter.

9. The wearable apparatus of claim 1 , wherein the second sampling rate is greater than the first sampling rate.

10. A method of selecting a sampling rate, comprising:

receiving, from at least one battery of a wearable device, an indicator of a charge;

determining an available capacity of at least one memory of the wearable device, the at least one memory storing measurements from at least one sensor configured to measure at least one property associated with a user of the wearable device;

receiving, from the at least one sensor, indicator of activity of the user;

determining, using a scoring algorithm, a score based on the indicator of the charge, the available capacity, and the indicator of activity;

sending a command to at least one transmitter to operate in a low-power mode or a high-power mode based on the determined score, the at least one transmitter being configured to send data to a device remote from the wearable device;

when the at least one transmitter is in the low-power mode, sending a periodic command to check a strength of signal from the remote device; and

when a response to the periodic command from the at least one transmitter indicates the strength of signal is above a threshold, sending a command to the at least one transmitter to operate in the high-power mode for a predetermined period of time;

when the command is to operate in the low-power mode, sending a command to the at least one sensor to operate at a first sampling rate based on the determined score; and

when the command is to operate in the high-power mode, sending a command to the at least one sensor to operate at a second sampling rate based on the determined score.

11. The method of claim 10 , further comprising: weighting, using the scoring algorithm, the indicator of the charge, the available capacity, and the indicator of activity to determine the score.

12. The method of claim 10 , further comprising: when the command is to operate in the low-power mode, reducing a frequency of uploads to the remote device.

13. The method of claim 12 , further comprising reducing the frequency of uploads only when the available capacity of the at least one memory exceeds a threshold.

14. The method of claim 10 , wherein:

the command further comprises a command to operate in a medium-power mode, and the medium-power mode has at least one of a range of communication or a transmission rate between those of the low-power mode and the high-power mode.
