How Smart Locks Use Battery Power

Smart locks are categorized based on the “protocols” used to communicate with smart home systems and with smart-phones. There are three main types of communication protocols: Bluetooth, Wi-Fi, and Z-Wave.

Smart locks use power differently depending on how they communicate. Below is a comparison of how different smart locks use power based upon their communication protocol.

Bluetooth-compatible locks

Bluetooth is a popular smart-lock protocol. It’s known for its simplicity and ease-of-use. Bluetooth-based locks are low on power and last a long time. The batteries in a Bluetooth-type smartlock can last for 12-20 months.

Bluetooth-based smart locks are efficient because they use very little energy and have a low frequency. A Bluetooth smart lock connects with your smartphone only occasionally, so it has a lower impact on your battery.

However, Bluetooth’s greatest quality is also its greatest undoing: the low frequency makes connection possible only in short ranges. Only when you’re within 300ft or lesser can your phone connect with the smart lock. This means you cannot do things like granting entry to people while you’re away.

Z-Wave Locks

Z-Wave is another popular communication protocol for smart locks. Z-Wave smart locks can be connected to a smart hub instead of a smartphone, unlike Bluetooth. The smart hub must be plugged in and connected to a WiFi router. Once you have completed the setup, you can access your smart locks from anywhere.

Z-Wave-compatible locks are energy-efficient, which is a big advantage. From what we can tell, their batteries can last for a long time—think 12 to 18 months.

The only perceivable downside to Z-Wave smart locks is that you need to buy a smart home hub like Samsung’s SmartThings. Still, getting a smart home hub is beneficial in some situations—like when you have other smart home devices.

Wi-Fi locks that work

Wi-Fi, apart from Z-Wave is the most advanced communication protocol. Typically, you’ll install an accessory to make the connection between your smart lock and your Wi-Fi network. Once you’re done with that, you can control your lock from anywhere, so long as you have an internet connection. You can unlock your door remotely to allow people entry in your absence and monitor your lock’s activity.

But, Wi-Fi-based locks have a downside: they use less battery life. Wi-Fi smart locks consume more power than other locks. According to reports, Wi Fi smart locks last for 1-3 months.
