Battery life depends on a number of factors including the number of recordings, duration of recordings, distance from the Smarthub, ambient temperature. Based off 5-6 minutes of recording a day, you should be getting 3-4 months between charging. If you are using the cameras in a high traffic area, you should consider an outdoor AC power supply or at least a solar panel. There is the additional benefit of Arlo Foresight with AC power - 3 seconds of pre-recording before the motion was detected in your video clips. The other aspect that a lot of people don't realise is that with Activity Zones, your camera still records and transmits video on motion detection. The video is analyzed by the Arlo cloud servers and they decide if the video goes to your library. So if there are swaying trees in the view that trigger the camera, you might be draining the battery with recordings that don't make it to your library. One way to check this is to compare what is saved to local storage vs what is in your library
