SMALL WI-FI DEVICE ENERGY RECORD

Prepared September 8, 2026. Editable planning and measurement worksheet.

Use exact hardware manuals and an appropriate measurement setup.
This sheet specifies no generic wiring, battery rating or radio approval.

Device/module/board/antenna/enclosure:
Firmware/SDK/configuration:
Payload bytes, reporting interval seconds and required confirmation:
Power input/voltage/measurement instrument and sampling settings:
Loads included or excluded (regulator, host, LEDs, sensors, display):
Test access point, location, signal conditions and application endpoint:

State / duration seconds / current mA / voltage V / measurement source:
Boot or wake:
Associate/authenticate/address:
Connect application/send/confirm:
Retry or recovery:
Sleep:
Cycle duration and repeat count:
Peak supply demand and observed minimum voltage:
Delivered records, failed attempts and time to confirmation:

At one voltage and measurement boundary:
Average current mA = sum(current mA * state duration s) / cycle duration s.
For different rails, compare energy at a common input and include losses.
Separate battery capacity, temperature and cutoff analysis is required
before estimating real battery life.

Fictional example, one 300-second cycle:
120 mA for 3 s, 0.05 mA for 297 s -> 1.2495 mA average.
120 mA for 15 s, 0.05 mA for 285 s -> 6.0475 mA average.
These invented values exclude other loads and predict no actual product.

Repeat under intended enclosure conditions and supported recovery cases.
