Your battery didn't go from 100% to 0%, with 30% of that being Ingress.
If your phone is currently at 90%, and Ingress is the only thing you actively did since your phone was last at 100% - then Ingress used 3% of your battery. So what used the other 7%? Still pretty small.
The questions are: how far from 100% did you go? And what used the other 70% of that number?

Haven't detected any drain on iPhone 12 with iOs 16.2(?) of my gf's young sister. What's Your specs?
Native refresh rate probably is the culprit here, your device is likely too old to handle the higher FPS
