How long does the battery last, and how do you charge it?

According to our engineering tests, Clever can be opened thousands of times without a single recharge. When it does run out battery, Clever recharges extremely quickly using any micro USB cable and smartphone charger. Plus, you can always view your Clever lock’s current battery life through the official Clever App.
