The following reasons may cause the battery lifetime to not as expected:
Battery quality and cold temperature will affect the battery lifetime.

Too many unwanted false triggers cause the battery to drain quickly: branches or weeds that can be blown by the wind, and trigger the capture.

Excessive settings cause the camera to capture too many redundant and repetitive pictures, leading to fast battery consumption.

Please try the following trouble shootings:

Please use brand new batteries to power the camera, and use 1.5V lithium batteries when the weather is cold to get a better battery lifetime.

Set the camera working mode reasonably according to the usage scenario.

Check the camera settings such as Photo series, Sensitivity motion, shot lag, etc. To reduce unnecessary triggers. For common usage, we recommend ‘Photo series’ is 1 Photo, ‘Sensitivity motion’ is Middle, and ‘shot lag’ is 10s.

Video mode requires the camera to stay in action longer, which will consume the batteries faster. Also, the longer the video, the faster the batteries will drain. To conserve batteries, limit the video length to 30 seconds.

Avoid false triggers: avoid objects such as branches or weeds that can be blown by the wind when placing the camera. If the frequency of using the camera is very high, we recommend using an external power supply to power the camera.
