1. A computer-implemented method for managing power modes of a continuous analyte monitoring system, comprising:
monitoring, by a controller of a sensor electronics module and while a transcutaneous analyte sensor is positioned in a body of a host, counts associated with signals received from the transcutaneous analyte sensor for a first period of time, the signals corresponding to a measured analyte;
upon determining a first number of counts associated with the signals received from the transcutaneous analyte sensor during the first period of time exceeds a first threshold number of counts that is associated with the first period of time, initiating an operational mode of the sensor electronics module, the sensor electronics module transmitting estimated analyte value data to one or more display devices in the operational mode;
while the transcutaneous analyte sensor is still positioned in the body of the host and the sensor electronics module is in the operational mode, monitoring, by the controller of the sensor electronics module, counts associated with the signals received from the transcutaneous analyte sensor for a second period of time different in duration from the first period of time;
comparing a second number of counts associated with the signals received from the transcutaneous analyte sensor during the second period of time with a second threshold number of counts, different from the first threshold number of counts, that is associated with the second period of time, wherein a value of the second threshold number of counts is based on an expected number of a plurality of measurements of a current value from the transcutaneous analyte sensor that is indicative of an analyte concentration in a host within the second period of time, wherein the second number of counts for the second period of time divided by a length of the second period of time is equal to the first number of counts for the first period of time divided by a length of the first period of time, wherein the second threshold number of counts is less than the first threshold number of counts, and wherein the second period of time is less than the first period of time; and
upon determining that the second number of counts received during the second period of time exceeds the second threshold number of counts, maintaining the operational mode of the sensor electronics module.
