Yes, I'm sure a Shenzhen technician can replace a glued down iphone battery in no time. The difference is, a 9 year can replace, say, the battery on my Oneplus 2 in about 3 minutes, with the tools that are already in every tool box (no proprietary clover screw BS). I know, because my nephew did that for me recently.
