How long does the battery last?

On average, the Canary Flex battery life is two to three months of normal use. Canary calls the Canary Flex lithium ion battery an “extended-life rechargeable battery.” It only draws battery power when unplugged, so if you leave it plugged in at all times, it will use the battery as a backup power source.

Canary FlexCanary Flex also uses a passive infrared sensor. When the sensor sees motion, it activates Canary Flex’s camera and tells it to communicate with the servers, greatly reducing its battery usage when no motion is present. In other words, Canary Flex spends most of its time in sleep mode.

The battery status is always available within Canary’s app, and low battery alerts will notify you when it needs to be recharged. When it’s time to recharge, you can use the included propriety charging prong to give the battery a boost.

A few ways to extend the Canary Flex battery life is by changing how you use it. For example:

  • Only have the camera alert you of motion when everyone is away from home by enabling geofencing. This uses the location of your phone to know when you come and go.
  • Limit the number of times you check its live status. If you’re always pulling a live feed of your camera, it drains the battery life.
  • Extreme weather can also drain the battery life faster. Since Canary Flex is easy to move, you can bring it indoors when the temperature is very high or low.

Outlet power is an option

If you’d rather not deal with recharging the battery, you can still opt for plugging in your Canary Flex instead. One important note is that, while the USB cable that it comes with is weatherproof, the power adaptor that plugs into the wall is not. This means that you need to get a waterproof outlet cover to protect the AC adaptor if you decide to plug in Canary Flex.

There are some big advantages to plugging in the Canary Flex. First, when you want to view a live feed of the camera in the app, Canary Flex can give you a faster live view from the camera when it’s plugged in. This is because it’s not in sleep mode, but is always on.

We compared this device with a few other outdoor security cameras in our article Nest Cam vs Canary Flex vs Arlo Pro. There are some strong advantages and disadvantages. For example, the Arlo Pro has 7 days of free cloud storage, which is much more generous. But it also requires a base station (similar to a hub) to plug into your router. Head to that comparison for all of the details on the other cameras.

    I have a Canary Flex and it won’t charge. I don’t remember when I bought it. I have tried and tried to charge it and it won’t. What is the problem or do I have to buy another one.

    I had a canary all in one but sold that and now have a flex mounted outside which I bought brand new 1 year ago.
    I have it constantly plugged into the electrical socket at home and I look at the live feed about twice a week. The battery is alway dying on me and when I’m away it shows off line because of the battery. It’s always plugged in so this shouldn’t happen should it…
    I then take the camera off it’s mount and take off the magnetic cable for a few seconds and it will charge up to 100% but again only lasts about 3 days, Help…..
