If you think that's bad, you should read up on the procedure
to change a battery. The parts have to be "registered" with

a secondary market consisting of stolen batteries :-)

I wonder if they stole the idea from Apple? One of Louis Rossmann's
videos complains that you can't even swap batteries between two
identical recent iPhones without getting warning messages that you're
using an unapproved battery.
