what if i remove the battery of iphone and connect to computer

Then you are the first person to connect an iPhone battery, that was removed from the iPhone, to a computer.

Best guess. You'll have a iPhone that doesn't work connected to a computer.

Don't you mean a battery connected to a computer? 😁

Oh thats easy. Twenty years too late you invented the portable computer. 🙂

I'm always too late to the party. 😁

It's still a good idea though. Maybe Apple can find a way to cut you a slice of the pie.

Yum! I like pie. 😀
