Eufy Doorbell and iPhone battery

Yesterday, I installed new Eufy wired door bell with chime. It is really nice door bell, video quality is awesome and working good except I noticed app is using quite a bit of battery on my iPhone!!! Since yesterday, battery usage is 56% just for eufy app on my XR. Is this normal? Also, I had few alerts today saying ‘human’ at the door but there was no one…just wind!!! Can that be adjusted? Thanks
