This is today, I charged my phone up to 92% and 4 hours later is at 73%. I used my phone only for a few calls.

In my case, the data saver is off.

What is a few calls? If you talked for more than 2h with so so reception, then I'm not surprised to see a 20% drop. Considering that you've also had some app working in the background using a lot of WiFi. The problem is that Android stats doesn't show everything, it tells you half of the story which makes it hard to read even for us

10% per hour of being on call? Dude thats straight up battery stealing if you ask me. For me it's 7-8 percent every hour with location off and that's decent battery life. Not the best if you ask me

i think same issue as what i am experiencing. battery is draining and phone is warm/hot near the vent side even on idle. i had a lightning cover but system lighting is disabled. Does screen refresh rate makes your phone warm? i tried it on 60 90 and 120 and same result even on idle. draining is evident.

Going through the menu on my phone to see which options can be turned off:
Here is another one under Developer option - Wifi scan throttling

These are only guesses now, so feel through to ignore.
