Battery life: 6:11 hours

Our Observations
With Leica Calonox View, the manufacturer states that the battery life is approximately 5 hours. We tested the device, and our measured time was 6:11 hours.
We tested the device at 22.7 – 24.5°C, as you can see in the video. The temperature was similar to the temperature that is usually used for testing.
Please keep in mind that while testing the device, we did not use any functions. Using different functions (such as video recording, Wi-Fi, etc.) usually affects the battery, so we can expect that the battery life will be a little shorter in real-life situations.
We tested the device with the default settings, as it comes out of the box.
Leica Calonox View monocular has a built-in battery, which you can charge with the type-C charger.
This thermal monocular also has a Standby option, which is a useful battery-saving feature. If you wish to enter the Standby mode, you just press the on/off button. To use the device again, you must press the button again, and it becomes instantly responsive to users’ actions.
The device is a bit bulkier and heavier, but it is still comfortable to use. It has a very nice and smooth design with Leica’s classic features. With the purchase of the device, you also get a case, which is a nice touch. It is easy to handle, and the buttons are comfortable to press, even if you are wearing gloves.
