How to Improve Your August Smart Locks Battery Life

While you can’t use rechargeable batteries to boost your August smart lock’s battery life, there are other proven ways to improve its battery life. Of course, August smart locks have good battery life and you only need some little tweaks to ensure the batteries are correctly utilized.

So here’s what you need to improve your lock’s battery life:

1. Proper Installation

If your lock isn’t correctly installed, odds are the errors may overwork the motor which could reduce its battery life. So you want to ensure your lock is correctly installed to prevent the motor from working harder than it’s programmed.

You should use the tailpiece adapter and ensure you get the wing latches in the right position—properly seated. If you’re not sure how to get your lock correctly installed, it’s best to have a locksmith handle the installation.

2. Improve Your Wi-Fi Signals

For Wi-Fi locks, they are equipped with Wi-Fi chips that capture and maintain the connection. And when you have poor Wi-Fi signals, the chip is forced to work extra hard to maintain a connection, which could overwork the battery and hence shorten its life.

You can prevent this by bringing your router closer to your front door and other doors you have the August Wi-Fi lock installed.

3. Reduce Deadbolt Friction

Friction between your deadbolt and the strike plate in your doorframe can force the motor to exert more force to make movement possible, and this could affect the battery life negatively. Make sure your deadbolt and strike plate are properly aligned to prevent friction during deadbolt movement.

4. Get an August Connect Wi-Fi Bridge

Built-in Wi-Fi locks consume more energy than other smart locks. This is because of the communication protocol—Wi-Fi. To improve battery life, August recommends using its Wi-Fi Bridge instead of your lock’s internal Wi-Fi to control your lock remotely. This helps to rest your internal Wi-Fi access point and thus reducing battery consumption. Read more about connecting your lock to a smart hub.

How to Check your August Smart Locks Battery Level

You cannot check your August lock’s battery level — whether through the app or the smart lock — as August has made no provision for that. However, you will get notifications when your battery is running low and needs replacement.

You may start getting notifications when your lock’s battery power is down to 25%. The notification will appear on your phone screen—perhaps your unlock screen, depending on your phone configuration. Also, your August smart lock may flash red light at intervals, which signifies low batteries. And you will get other push notifications and emails daily until the battery finally dies off.

Note: At 25% battery capacity, you can continue using your lock if you don’t wish to replace the batteries immediately. But timely battery replacement can help prevent a situation where your battery dies off and locks you out.
