Measure Battery Runtime Accurately

Estimating IoT battery life requires understanding how the device consumes energy across its full operating cycle. Battery-powered devices may spend long periods in sleep or idle states, then briefly enter higher-current modes for sensing, processing, receiving, transmitting, or peripheral activity. Even short active events can have a major impact on total runtime when they repeat over months or years of operation.

Engineers need to move beyond simple average-current assumptions and understand how each operating state contributes to total charge consumption. By characterizing the device’s real activity cycle, they can create a more accurate battery-life estimate, compare design choices, and identify which behaviors have the greatest effect on expected runtime before deployment.

IoT Battery Life Estimation Solution

Estimating battery runtime requires measuring current drain across real operating states and converting the measured charge profile into a runtime projection. This solution combines a direct current power analyzer, source measure units for battery emulation and current measurement, a radio frequency event detector, and event-based power analysis software. The workflow supports synchronized current, radio frequency, and direct current event capture so engineers can associate sleep, idle, receive, transmit, and subsystem activity with charge consumption. The measurement can be used to estimate total battery life and identify which events or subsystems contribute most to current drain.
