I’d lean toward the way you have it now. I like having the owner profile as my daily driver. Any app that I have doubts about gets its own profile.

If you haven’t already, check out the Graphene forum and search for profiles. There have been lots of discussions about this, and you’ll find some good examples for various privacy/security needs.

I’ve had the opposite experience. I’m on a Pixel 8 running Graphene. So far today (8.5 hours since last charge), I’m at 87%. The screen time meter says 90 minutes of screen time since last charge. I’ve been running Bluetooth for about 4 hours, and WiFi full time.

I’d typically be under 60% at this point when I was on stock Android.
