Define the Problem

A battery-powered device was failing to achieve its target operational life, limiting practical deployment.

Diagnose the Root Cause

Power profiling identified that several peripherals remained active during low-power states, causing significantly higher energy consumption than expected.

Key engineering challenges included:

• Strict battery-life targets

• Multiple active subsystems

• Limited hardware changes possible

• Existing firmware architecture

Deliver the Solution

We redesigned power management behaviour and optimised firmware scheduling to aggressively control peripheral activity and sleep states.

Key Outcomes

• Approximately 90% reduction in power consumption

• Achieved target battery life

• Improved operating efficiency

• Increased deployment viability
