Rule-of-thumb model: 80% usable battery, typical radio transmit current and airtime, plus a small sleep current and protocol overhead. Ideal conditions: excludes self-discharge and retries. Real results vary with temperature, signal quality and firmware. Treat as a planning estimate; battery life is shown capped at 10+ years.
