Theoretically you might be able to solder it to inside of USB connector, but that would risk normal USB operation.
I think in many phone there would no be enough free space between case and electronics in many thin phone models.

Is there any unuversal way of attaching the coil to smartphone internals, so it would sit under the phone cover inside the phone rather than being attached externally?

https://www.youtube.com/watch?v=CEGlmQS692w

In this video I’m testing a dangerous Wireless Charger (Qi Charger) from China. The efficiency is about 45% in the very best conditions.

The receiver has an overheating component, probably a resistor. It gets steaming hot and melts through the cover. You are supposed to put the receiver inside your smartphone, so it is squeezed against the battery. Yes, a red hot resistor is pressing directly onto the flammable Li-Ion battery! This amazing device is going to set your mobile phone on fire or make it explode.

“coming up: Fireless charger”

In this video I’m testing a dangerous Wireless Charger (Qi Charger) from China. The efficiency is about 45% in the very best conditions. The transmitter has a poorly aligned connector which you have to fix yourself before you can use it. But the best is coming. The receiver has an overheating component, probably a resistor. It gets steaming hot and melts through the cover. You are supposed to put the receiver inside your smartphone, so it is squeezed against the battery. Yes, a red hot resistor is pressing directly onto the flammable Li-Ion battery! This amazing device is going to set your mobile phone on fire or make it explode.
