Can fully charge, and camera dead in two days.
Hello, thank you for your feedback 
Generally, under normal triggering frequency, battery life should be significantly longer than two days. We need to further confirm whether the high-frequency triggering is draining the battery or if there is a battery malfunction. The following aspects may need to be checked:
Approximately how many times has the camera triggered recording in the past two days? (e.g., dozens or hundreds of times per day)
Suggestion: You can appropriately lower the sensitivity setting and adjust the detection range to reduce invalid recordings.
Is the current weather cold? Low temperatures can affect battery life.
If the above measures do not resolve the issue, you can find online support on the Aosu app; they will provide you with more professional solutions. Hope this helps, thank you for your support.
