Aura shouldn't noticeably affect your battery in normal use, because blocking is handled by iOS rather than by anything Aura runs in the background.
Two things do use power while they're on screen:
- Camera Reps, because the camera and pose detection are running. A long set
uses roughly what any camera app would.
- A focus timer, if you leave the screen on to watch it. Lock your phone
instead. The session keeps running, and that's rather the point.
If you're seeing real drain outside those, check iOS Settings, Battery, and see what it attributes to Aura. Send us a screenshot at help@downloadaura.app.
