Verify Battery Life Targets

Verifying IoT battery life targets requires measuring whether the device can meet its expected runtime under representative operating conditions. Battery-life requirements are often based on assumptions about sleep time, active time, duty cycle, radio usage, processing activity, and battery capacity. Small changes in firmware behavior, operating frequency, or subsystem activity can cause actual runtime to fall short of the design target.

Engineers need a repeatable way to compare measured device behavior against the battery-life requirement. By evaluating current consumption across the operating modes that define expected runtime, they can determine whether the design meets its target, quantify any runtime gap, and identify which activities may need to be adjusted before product release.

IoT Battery Life Target Verification Solution

Verifying battery life targets requires measuring current drain across representative device operating modes and converting the measured charge profile into a runtime estimate. This solution combines current measurement, event capture, and event-based power analysis to align sleep, idle, transmit, receive, and subsystem activity with charge consumption. Engineers can calculate runtime from measured current behavior, expected duty cycle, and battery capacity, then compare the result against the device's battery-life target.
