This tool is intended to estimate the power consumption of a sleepy TI 15.4-Stack Sensor Device using SimpleLink TM CC13X2/CC26X2 Wireless MCUs: devices which provide ultra-low power performance for every power constraint.

Through this tool, it is possible to assess and optimize the potential battery life by configuring stack and usage parameters. However, this tool only estimates the power consumption as several other factors (board design, transmission retries, etc.) can draw additional current. This tool assumes the device will operate under room temperature conditions.

This tool does not include the first time network join operation or any power consumption due to the device losing the parent or rejoining the network (if any). Results do not include current consumptions due to any peripherals such as LED, LCD, button presses, and active sensors; any of which will increase the current consumption. Results do not factor in battery condition, age, temperature, discharge rate, and other factors as they will vary based on the battery used.

In order to accurately determine the power consumption for a sleepy end device under specific user conditions refer to the 'Power Configuration' section of the TI 15.4-Stack User's Guide for a guideline.
