Duty cycle
Measure real active time.
Boot, sensor warm-up, radio association, retries and firmware behaviour can make active periods longer than a planning assumption.

POWER PLANNING
Model the battery assumption.
This simplified estimator converts a daily active/sleep duty cycle into approximate mAh use and battery life. It is a planning aid, not an electrical design sign-off.
Enter non-negative duty-cycle values, keep active time within 24 hours and use a battery capacity above zero.
DIRECTIONAL ESTIMATE
Estimated battery life—
Estimated days—
Average use / day—
This intentionally simple model excludes temperature, self-discharge, regulator losses, battery ageing, retries, network conditions and peak-current limitations. Validate on real hardware.
READ THE RESULT CAREFULLY
A useful estimate tells you what to validate next.
Battery life is often dominated by assumptions that a simple average-current model cannot see. Treat the result as a sensitivity check rather than a product guarantee.
Environment
Temperature and ageing matter.
Usable capacity changes with chemistry, temperature, discharge profile, self-discharge and battery age.
Network
Retries can change the picture.
Weak coverage, reconnection and repeated transmissions can materially increase radio-on time and energy use.

This estimator is a self-service engineering tool for exposing assumptions early. Critical battery-life decisions should still be validated against real hardware, operating conditions and project-specific engineering data.
