Extending battery life

An analyte monitoring system comprising:

• an analyte sensor;
• a display device;
• and
• a transceiver including a battery and configured to (1) execute functions including communicating with the analyte sensor and communicating with the display device, (2) be capable of executing concurrently two or more of the functions, and (3) avoid executing concurrently one or more of:
• (a) a number of functions greater than a maximum number of functions;
• (b) functions including one or more high current demand functions;
• and
• (c) two or more functions that would have a combined current demand higher than a current demand threshold.

A method comprising:

• using a transceiver to perform a battery level reading function to determine a battery level of a battery of the transceiver;
• using the transceiver to convey to a display device one or more of the determined battery level and a battery level alert, alarm, or notification generated based the determined battery level;
• and
• using the transceiver to time performance of the battery level reading function such that it does not occur at the same time as a period of high current demand on the battery.

A method comprising:

• using transceiver to execute functions;
• using the transceiver to concurrently execute two or more of the functions;
• and
• using the transceiver to avoid executing concurrently one or more of:
• (a) a number of functions greater than a maximum number of functions;
• (b) functions including one or more high current demand functions;
• and
• (c) two or more functions that would have a combined current demand higher than a current demand threshold.
