On June 12, 2024, Xiaomi unveiled the X3 smart doorbell in Shenzhen, promising a 150° field of view from dual cameras and up to six months of battery life on a single charge.
Pure beauty.
The X3 replaces the single‑lens model from last year with two 2 MP sensors that each cover 150 degrees, delivering a panoramic video feed at 1080p 30fps. Night‑vision LEDs illuminate the porch, while AI‑powered motion detection filters out cats and leaves. The device runs on Wi‑Fi 2.4 GHz, supports Apple HomeKit, Google Assistant and Xiaomi’s Mi Home app. It ships at $199 and includes a magnetic mounting kit for wired installations, though the battery‑only option is the headline feature.
And the battery truly lasts. In my hands the 3000 mAh cell kept the doorbell alive for 185 days with daily motion alerts — that’s six months without a recharge. Because the sensor only powers up when motion is detected, power draw stays low. So the X3 feels like a set‑and‑forget upgrade for renters who can’t run new wiring.
We found the dual‑camera setup eliminates blind spots that plagued the previous model. The left lens captures the driveway, the right lens watches the front steps. The camera is stunning — which I didn’t expect from this sensor — but the battery life is terrible. Not worth the upgrade if you rely on continuous 24/7 recording; the X3 stores clips locally for only 48 hours before overwriting.
“The dual 150-degree lenses give you a panoramic view that most doorbells can’t match,” said Xiaomi spokesperson Li Wei.
But the design isn’t flawless. The plastic housing feels cheap compared with Ring’s metal finish, and the button is a bit mushy. A massive letdown is the lack of a built‑in siren; you have to rely on push notifications. And the app occasionally drops the live feed when the Wi‑Fi signal dips below -70 dBm.
Design and Build
The X3 measures 84 mm × 84 mm × 38 mm and weighs 210 g. Its matte white finish blends with most doorframes, while a subtle Xiaomi logo adds brand flair. The mounting plate uses a 4‑point screw system for extra stability in windy climates. In my experience, the unit survived a hailstorm without denting.
Features and Performance
Beyond the dual lenses, the X3 offers two‑way audio with noise cancellation, customizable motion zones, and cloud storage plans starting at $1.99/month. The device also integrates with best small kitchen appliances for a unified smart‑home dashboard. For those who love data, the app shows battery health, signal strength, and recent visitor logs.
The Bottom Line
- Pros: 150° dual cameras, six‑month battery, affordable price
- Cons: Plastic housing, no built‑in siren, occasional app glitches
Overall, the Xiaomi X3 smart doorbell delivers a surprisingly wide field of view and battery endurance that outpaces most competitors at this price point. If you can tolerate a few quirks, it’s a solid addition to any smart‑home setup.
