Use USB for ... > now out of charge. Help!

[blueade7]

In order to attach my phone (Nokia 7.1 on Android Pie) to a DAC/headphone amp, I set my phone via developer options to "use USB as audio".
I thought I'd changed it back to "use USB as charge", but perhaps I didn't. :-(
Anyway, the phone has now run out of charge, and will not re-charge or turn back on. I'm now pretty stuck. The battery is non-removable and does not charge wirelessly.
Any ideas?

Alternatively it could just be a problem with the usb port. To help diagnose the cause of the problem - whether my fiddling around with the usb functionality or a hardware problem - can anyone answer whether the phone *should* charge anyway even if set to use USB as audio or midi?

Welcome.

Was that in the option called Select USB Configuration? In the phone I'm using now, that is set to MTP rather than Charging - presumably as a default setting since I've never had occasion to change the setting on this particular phone - and yet it charges normally, and Developer Options are switched on.

Problem solved. Unclear what problem was - perhaps frozen screen when powered off. Suddenly leapt back to life with 30 % charge.

Thanks for your help. You're right - it charges regardless of USB function selection.

I'm glad that all is well.
