The accessory is fine. It's my charger. It works. There's no issues with it. I just want to turn off the pop-up permanently in software (again, the device and charger are fine, all ports are clean, everything works always, it's just being a bitch likely due to it being third party). I'll literally jailbreak my device to do it. please

The only time I ever had an Apple device read a charger as an accessory, was the charger being on it’s deathbed. I couldn’t tell you how to turn that popup off, but I would suggest replacing the box you’re using; if your iPad can’t define that box as a charger then there’s something internally wrong with it.

It's a USB-C to lightning cable that plugs into a port in my computer directly (I use this thing to draw, so I plug it into my PC to mirror screens with it). After a bit of testing today, however, the dastardly pop-up disappeared, although it did show up when I had literally nothing at all connected to my device upon waking it from sleep mode(?!)

The pop-up seems to have not haunted me further after that, no matter how much I wiggle the cable or how many unofficial external accessories (ooh, spooky) I connect. I don't...have any answers for why this happened to begin with. It just decided that it's fine now.
