The on-off switch on my iPhone 5 misbehaved once in a while. You could
press it and nothing would happen. Maybe once every 50 times, no biggie.
So, I was in Annapolis near the local Apple store this morning and when
the store opened at 10 am, I asked if one of the techies could see if
there was a speck of dirt stuck under part of the switch, or maybe just
replace the switch.
"We'll just give you a new phone," he said. He transferred my SIM card
to a new phone, I "registered it," and then downloaded the nightly
backup I do from the Cloud, and, in 20 minutes, I was on my way. The
"old" phones are shipped to an Apple depot, where they are taken apart,
fixed, and sold as refurbished phones.
I don't know what was wrong with the switch and...I don't care. 
You seem to be going to your Apple store for repairs quite frequently.
