Apple Self Service Repair makes fixing an iPhone on your own easier... sort of
If your iPhone needs repair, you should probably bring it to the Apple Store to get it fixed, right? Well, maybe. I recently brought my iPhone 8 Plus to that store for a battery replacement, and the Apple "genius" accidentally broke my phone entirely! Yeah, they did the right thing and replaced it with a working iPhone 8 Plus, but still, it was a massive hassle to restore everything.
Of course, if I was able to replace the battery myself, I probably would have done that instead. I am no expert though, and I would probably not be happy with the results. Plus, Apple has historically frowned upon consumers doing repairs on their own.
