iPhone 6s, iOS 12.0.1
Plugging the phone into a computer to charge produces an "Unlock iPhone to use accessories" message and the phone refuses to charge.
How do I fix this nonsensical behavior? I know Apple added a privacy feature where the phone disables the data connection on lock to thwart hacktools that plug into the phone and brute-force the access code, but there's no reason to disable charging-only while it's locked. In this particular case, I only need to charge the phone over a computer; it doesn't need data access.
I'd like to avoid having to buy additional hardware such as a separate power-only limited USB cable.

Are you sure it's because the iPhone is locked? Maybe the USB port just won't supply enough power. (In the latter case, it may in fact be charging, just very, very slowly.)

I'm 100% certain that the USB port works properly. It worked fine before updating to iOS 12. Additionally, if I unlock the phone and plug it in, it charges normally on that computer. I assume a low-power port would produce a different error, likely a silent failure such as apple.stackexchange.com/questions/287157/…

Just to be clear, a lower power USB port is working properly—you could in fact argue it's the higher power ports that are borked, because they're technically breaking the USB spec. But yeah, if the phone charges once it's unlocked, your assessment is likely correct.

No, but I'm 100% certain the cable is OK as well. It works with a regular plug charger. Additionally, if I unlock the phone it charges normally on the computer, so the cable isn't broken.

The iPhone will charge from a pure charging port, so you just want to put a data blocker on the USB so that the phone won't reject a computer and see a charge only device.
- https://www.amazon.com/PortaPow-3rd-Data-Blocker-Pack/dp/B00T0DW3F8
There are many of these and you generally get what you pay for in low cost USB accessories. I'd expect to pay $10 for either one good blocker or a pair in the US. I know you didn't want to buy hardware, but unless you can get your computer to stop signaling it's a USB data connection, iOS is going to shut down the port since that's "what it do".

Voting this up for being partially helpful; however an answer needs to work with my existing hardware to be properly accepted. As an interim solution I temporarily disabled the USB restricted mode while waiting for Apple to implement what should have been obvious from the start. Moral of the story: unreasonably strict security "features" are no practical protection if they significantly damage usability simply because people get fed up and disable them
