Peephole Cam Battery drain

I have had this peephole cam for 2 weeks now and have tried every setting to extend the battery life. It uses at least 4% a day which means I would have to replace the battery after less than a month. I would be happy if I could get the usage to 3%, then that would last over a month and could change it when I change my furnace filter, etc. Settings are snapshot capture off, motion frequency minimal (periodically), advanced motion detection on, video recording length 20 seconds, motion zone setup for only 10ft front porch, and motion sensitivity set to approx. 15%. But still drains 4% a day. Tried new battery. Guess the problem is that it triggers every time the front door opens so alerts mount to XXXX a day. Any way to extend battery life? Post about changing knock detection makes no sense – it is motion. Forgot to mention wifi is in the same room, RSSI -45ish
