The solar camera of the low-power type uses the PIR motion detection function. Only the detected person will trigger to start working, and it will be in a sleep state at other times. Under normal circumstances, the camera can continue to work for a long time in the absence of sunlight, depending on the number of triggers. A fully charged solar camera battery can typically provide 5 to 7 days without sunlight, assuming the camera works 24 hours a day.
In addition, the total capacity of the battery will also affect the duration of the charge. It depends on the type of battery.
Sometimes the battery is drained quickly, probably by leaving the app open all day/night to drain the battery. So as long as you regularly check for notifications or other notifications, the battery will never go away. As long as the number of triggers is small, almost no power is consumed overnight.
