Can you wire the USB power to the battery contacts…?

It sounds like a good idea until you remember that USB provides 5V and the battery contacts are designed for a Li-ion battery and its management circuitry.
Wiring USB directly to the battery contacts would basically be like noticing your car runs on petrol and pouring it directly into the engine instead of the fuel tank. The general concept of “engine needs fuel” is technically correct. The implementation leaves something to be desired.
The USB port and the phone’s power-management circuitry exist for a reason, and bypassing them could damage the phone or make it behave in exciting new ways.
A properly regulated dummy battery, however, might actually work. Unfortunately, that means I now have another terrible idea to investigate.
