Can anyone help me out here?
- WiFi using 50% of my battery. What the hell?
- Android system using 20+ GB of data.

I find that my battery drains most when I'm on wifi, while wifi calling is active. It keeps wifi on, and for that to happen, the phone needs to be awake more often. If I turn off wifi calling and leave wifi connected, it can still "sleep". Not sure if you're not using wifi calling. Just my own observation.

Is Google Photos set to backup when on WiFi? Similarly, if you're on Instagram and YouTube those site can consume data which utilizes WiFi. Think that can drive the WiFi process up, which are shown as part of the Android OS utilization.
