Yoga5841
I'm using a Pixel 8a. I also have a psim and a esim, and the radios seem to be kind of power hungry, as I loose 5% of the battery overnight (so without any interaction with the phone + no Internet connection active).
Yoga5841 "system apps" (which are annoyingly placed at the bottom of the list)
Never scrolled to the bottom, and I never knew that was there!
Yoga5841 When I view by systems, it's about 80% system (IDLE), 8% WiFi, and everything else is less than 5%.
You are not using cellular, are you? In my case, I have around 40% system (IDLE) and around the same for the mobile network.
