Rechargeable battery packs (often with a spare included) reduce downtime, but real-world longevity varies by settings like always-on face scanning and Wi-Fi usage, ranging from weeks in max scanning mode to months with power saving.
Battery design is a tradeoff: AA cells are easy to replace and often quoted to last many months to about a year, but some reviewers prefer rechargeable options and note that heavy Wi-Fi use can increase drain.
Battery life is often rated around 8 months on four AA cells and many users report strong endurance, while a few long-term accounts cite faster drain. USB-C emergency power and a physical key mitigate low-battery scenarios.
The lock uses four AA batteries with widely cited claims of roughly 12 months of life, while keypad battery life is often quoted around several months. Downsides include no battery percentage meter for the lock in the app and at least one report of unusually fast keypad drain or loose batteries during installation.
Battery life is a recurring pain point on Wi-Fi setups, often quoted around three months and sometimes closer to 5–7 weeks in heavy use, and the app commonly lacks a clear battery percentage until late in the cycle, making low-battery lockouts more plausible.
