 So Matt, thank you. He says, I just listened and was excited to hear that Dave, you have the same problem I'm having with my iPhone 12 Pro battery. So mine is a 12 mini, his is a 12 Pro. Says it only drains excessively at home and on Wi-Fi. At home on Wi-Fi, I've seen battery drainage of at least seven to 10% per hour with minimal to no use of the phone at all. It just sits on my desk and I can see the battery usage chart show a scary rapid decline. Yes, exactly the same for me. He says, if I travel anywhere else, including being on Wi-Fi, my battery drainage stabilizes to a normal like 3% per hour. That's not fantastic, but it's definitely much better. He says, I've done Google searching up the Wazoo and haven't found many specific cases that mimic what I'm seeing. Like you, I also thought it must have something to do with the location setting, but for me, turning off those didn't help. Okay, same. He says, I've also tried limiting background updates, et cetera, et cetera. He says, I even drew a pentagram on the floor with candles and sacrificed a chicken to appease the angry iPhone gods, but all to no avail. He says, what I found actually helped much to my surprise was resetting my network settings. And this is the same thing I wound up doing over the weekend and it worked. He says, that forces me to reenter all of my Wi-Fi passwords again. I'll get to that, because it shouldn't. He says, and reset some cellular settings, but it does have a noticeable improvement on the battery drainage problem at least for a while. After resetting network settings and using my home Wi-Fi, I see the battery drainage go back to the usual 3% per hour with minimal usage. It doesn't seem to last very long for him. He says, I find that sometimes when I leave and come back to my house, if I don't use a Wi-Fi network in between, the battery will stay good. But if I say, go to my office and use the office Wi-Fi and then come back home, the fast battery drain will start again. Even then, however, the pattern isn't 100% consistent. He says, I'm sure resetting network settings is just masking whatever the real issue is, but at least it helps. So...
