Real-World Testing Reveals Significant Battery Drain
The eufy E330 Video Smart Lock, featuring a 2K camera, doorbell, and fingerprint access, showed a significant gap between its advertised and real-world battery performance in a test by The Gadgeteer. While eufy claims 8–12 months of battery life, the lock lost 58% of its battery after just 11 days under typical settings, suggesting it could require recharging roughly every 20 days.
Video and Smart Features Come at a Battery Cost
The test found that reaching the advertised battery life requires disabling several key features, including video recording, auto-lock, and notifications. This highlights a major challenge for video-enabled smart locks: adding cameras and always-on smart features can significantly increase power consumption and create a trade-off between functionality and battery life.
Battery Life Emerges as a Key Differentiator
The findings underscore battery longevity and charging frequency as increasingly important factors in the smart lock market, particularly for camera-equipped models. This also creates an opportunity for DESLOC’s solar self-charging approach, which is designed to reduce the need for frequent recharging. For competitive comparisons and product listings, the messaging can emphasize “less charging, less maintenance” and the convenience of long-term, self-sustaining power.
