Power Saving implemented is to keep the power consumption to the minimum in order to extend the battery life while doing time-lapse shooting. This can be set in Settings on ATLI Cam App. You can either choose “On (Common)” or “On (Mandatory)”. The Mandatory mode is intended to keep the Power Saving active to further extend the overall battery life when a power bank/portable charger is connected. Power Saving is triggered when the following criteria are met. 1.Time-lapse shooting is in progress. 2. The ATLI Cam App is inactive for more than 10 minutes. It first turns off the Wi-Fi and then goes further to sleep while not shooting. When the time comes, it wakes up to shoot and then goes to sleep again. Please note that Status LED turns off while it is sleeping and then turns on (orange color) when it shoots.If the shooting interval is long, you will have to wait in order to see Status LED is on. It is important to note that the App won’t be able to connect to the camera anymore while the camera is in power saving mode. You will need to press the power button momentarily to turn on the camera (ready in 30 seconds when Status LED turns green).
