My kid's Pixel 8 has had GrapheneOS installed for quite a while. Recently it stopped accepting charge via USB - the screen SAYS charging, but if you put a volt meter on the USB line you see no current is being drawn. And if it's a fast charger, the voltage keeps resetting over and over... we tried plugging in while it's in Fastboot mode, no change. Have tried multiple chargers and cables, including dumb USB A-to-C on a simple 5V source. (sometimes you can get a trickle of charge, 1-2% but slowly)
It charges wirelessly OK, but I'd like to find out how much this might cost to repair. I'm assuming it's something about the PD charge controller chip or component nearby. Unless someone has board-level soldering skills I suspect we're looking at a new main board?

Pixels are known to have usb c ports that go kapootz and be a headache to repair
Seeming as you clearly know what you're talking about in terms of power draw amperes etc, I'd just stick to wireless charging, not sure if it'll be a grapheneos thing, but the charging board / BMS being funky

yes I'm quite sure the charge controller/BMS (or a nearby passive component) is faulty, I'm wondering if there's any hope of repair aside from replacing the whole main board? At first I thought Pixel 8 had the charging hardware on a daughterboard like some phones do, but apparently it does not. I'm gonna also guess that even if I find someone with surface-mount solering skills, the parts needed to replace whatever's gone wrong will be hard to come by. But before I commit to replacing the main board and/or junking this phone I thought I'd ask to see if I'm overlooking anything... (BTW we eliminated Graphene when trying to charge from Fastboot mode)
