If I replace the battery in an iPhone 6 myself and the phone doesn't work afterwards, does that defray the trade in value?

If you replaced it yourself.yes it does.

It will break. Get the iPhone X it's better

Yes it voids the warranty

Well yea. The phone is inoperable.

If I replace the Vulcan engine on my Taurus and try putting in a Duratec and I mess up and it doesn't work, does that lower the value of my almost worthless car? Yes.

A working car (or in this case, phone), isn't worth as much as a working one.
