  • USB Charging issue for two devices after update

I'm just here to report that my Pixel 4 XL has also lost the ability to retrieve charge data from the battery after the most recent update, so I don't think OP's issues are necessarily isolated incidents (aside from the moisture component). I understand that the device is end-of-life and I don't expect support for it, but I wanted to make mention of this issue because it might urge someone to take a closer peek to see if there's something that can easily be tweaked and rolled out in the next update.

My device caught the update when it was at 16% battery capacity, and after reboot, it couldn't be charged above 16%...at least according to the indicator and several other battery-monitoring apps. However, I've tested running a heavy load (recording 1080p video), and the level never dropped below 16%.

I believe my device is charging fully, but has lost it's ability to retrieve the charge state, and stuck at the level it was when the update occurred. Can't afford a new device right now, just gotta stick this one out until I can, but figure at least it's better than reverting to stock.

Don't mean to hijack the thread, but if rolling back to a previous build is the most logical step, I'd be grateful if someone could advise on that. Otherwise, I'll start my own thread, but I don't necessarily expect support and won't raise a stink if no one comes to my rescue.

    The original poster reported the devices, a 4a and a 5, would not charge, and also were reporting moisture and debris alerts. So your situation, with a 4 XL that is stuck at reporting 16%, seems like something independent, and I would recommend a new thread.

        You're right, they are different issues. However, I'll just note that after my issue had persisted for weeks, today I left my phone unplugged for a short time and discovered it had shut itself off, and would not turn back on with the power button. I plugged it into a wall outlet, the battery charge indicator showed it taking a charge, so I left it charging for a bit and after less than an hour it showed it had reached 94%, so I attempted to turn the phone back on and it worked! The battery indicator at the top of the screen now shows a full charge!

        I stumbled on this thread by searching for "GrapheneOS not charging after update", and this thread was the first result. I won't be making a new thread because the Pixel 4 XL is no longer supported and my issue seems to be resolved, but I'll leave this info here in case someone has the same issues I did, and found this thread by the same method.
