And how long does it last?
When I bought my last phone (a Moto G), one of the decision points was the fact it was actually made in Ft Worth, Texas.
7 months after I bought it, that plant was shut down. So much for helping support "American made"
Also, wafer fabs are literally multi-billion dollar facilities now. If you can influence even 1/10th of a percent of that price, then you can have a say where it's built.
