Will a battery-powered motion sensor really last years?

High-trust community threads broadly confirm that low-power Zigbee sensors like the Aqara P1 and Philips Hue routinely deliver 1–3+ years on a single battery in real-world use, though manufacturer claims of 5 years are best treated as best-case figures. Verified-purchase reviewers occasionally report shorter life when sensitivity is cranked up or the sensor sits in a high-traffic area.
