How Long Do Batteries Last In Smart Locks?

How long do batteries last in smart locks? The answer varies depending on various factors.

Smart locks that work with Z-Wave or Bluetooth can last up to two years without recharging. Yet, locks that link to the Wi-Fi directly only last one to three months.

This article will give you a complete answer for the battery’s lifespan.

Let’s read on to discover!

How Long Do Batteries Last in Smart Locks?

Bluetooth, Z-Wave, and Wi-Fi are the three types of connections available in electronic locks. The type you opt for affects the battery life.

Type of connection Battery longevity
Bluetooth 12 to 20 months
Z-Wave 12 to 18 months
Wi-Fi 1 to 3 months


Bluetooth locks are perhaps the most popular model. They’re famous because they’re affordable and typically simple to purchase and use. All you need is a mobile application, and you’re ready to go!

These devices are the most potent variants available. Depending on usage and the lock mechanism, they require very little energy and may last anywhere from one to two years.

Bluetooth appears to be a low-power frequency range. It isn’t too heavy on the battery because it simply interacts with your phone occasionally.


Z-Wave technology combines the benefits of both Wi-Fi and Bluetooth locks into one convenient package.

Z-Wave is a Bluetooth system that links to a hub within your house rather than a mobile phone. The hub is joined to Wi-Fi after being hooked in.

Rather than the battery-powered locking, the hub receives all of the actual power-intensive duties.

With a Z-Wave-based key, you may expect to use it for 12 to 18 months before having to charge the battery.

Z-Wave hubs can be expensive and hard to set. They do, however, allow you to integrate different devices, such as security systems.

Wi-Fi-enabled locks are the most sophisticated available. Regarding features, they generally include all the whistles and bells.

The gadgets are cost-effective and perform just as claimed. Many of them are overengineered and also have a wide variety of functions.

These devices can only last one to three months. Replacing the battery regularly is not a big deal, but it may be annoying to some people.

Factors Affect The Lifespan Of Batteries In Smart Locks

The lifespan of these batteries also depends on other factors, such as the frequency of use and weather.

Frequency of use

The more often you use it, the more battery it takes. This idea is self-evident, and it stands true for intelligent locks.

The battery longevity changes depending on the number of times you lock and unlock your door. The electronic lock employs the battery to perform this task every time you access your door.


Though it may come as a surprise to some, a study has shown that weather impacts the battery capacity of your smart lock.

Some batteries may drain quicker in certain weather conditions. Meanwhile, others will drain faster in other situations.

As a result, it’s critical to consider the battery’s temperature sensitivity before buying a product.

How To Extend The Lifespan Of Batteries In Smart Locks?

The battery longevity varies from model to model. The way you use it also plays a role in the battery’s durability. Fortunately, there are some tips to enhance its lifespan.

Use lithium batteries

The most excellent option for extending the life of electronic lock batteries is to get lithium batteries. They are more durable and reliable than regular AA (alkaline) ones.

Many people believe that a lithium battery will last twice as long as an alkaline cell. You should expect a lithium-ion battery-powered smart lock to last a very long time.

You may use a Z-Wave gateway with a lithium-powered lock to boost efficiency. This system offers more than just remarkable features. You also get a long battery life, which simplifies everything.

Before purchasing a smart lock, be sure it can run on lithium batteries. Using lithium cells in a non-lithium lock might cause a lot of problems.

Lithium technology is a good way to go 

Avoid deadbolt friction

Check that you have correctly aligned the lock and the strike plate in the door frame. Moreover, make sure there is no friction when you push the deadbolt.

The motor will have to work extra hard to move the deadbolt, which will decrease battery life.

Smart Locks With Most Durable Batteries

If you find replacing the batteries for your lock unpleasant, you can opt for the models equipped with long-lasting cells.


Schlage is a leading company in the industry that produces some of the top options.

If you’re looking for a lock with long battery life, the touchscreen deadbolt is the way to go.

The cells in this lock can last for one to two years before recharging.

The usage of lithium batteries, which last longer than ordinary batteries on average, contributes to the lock’s durability. It also connects your smartphone to the lock through Z-Wave technology.

As said before, the locks that link through Z-Wave have a longer lifespan than those that work with Wi-Fi.


Yale has been producing the most fantastic locks with cutting-edge technology. While they are more costly than the ordinary, they give sufficient value to warrant the premium cost.

The long battery life of many Yale locks is an example of what you can refer to as value.

The Deadbolt T1L and the Z-Wave Deadbolt, for example, offer long-lasting batteries. They are also the most popular products from the brand.

Like the other types on this list, Yale electronic locks are Z-Wave compliant. Above all, this feature aids in reducing energy drain and the advancement of better battery life.


The price, simplicity of use, efficiency, and elegant design of these locks have made them famous.

If you are looking for a lock that doesn’t require regular power maintenance, an August lock is a wonderful choice.

The August Pro, for example, is one of the best products on the market. This device is compatible with Z-Wave tech, which aids in battery life improvement.

If you don’t have a Z-Wave hub already, you’ll most likely need to purchase one. August’s long battery life makes it worthwhile to pay a little more despite the additional cost.


Kwikset is another excellent option to choose. You may want to get a 916 Touchscreen from this brand due to its battery durability.

Other Kwikset models share the same features, such as the SmartCode 909, 910, 914, and many more.

Because these devices work with Z-Wave for connection, Kwikset electronic locks feature long-lasting cells.

Smart locks are wonderful, but changing the batteries so often might make them less pleasant to use. As a result, you should choose a model that ensures power efficiency.

While purchasing electronic locks, you need to consider issues other than efficiency. It would be best to look for a lock that provides a good blend of functionality, reliability, and cost.
