Apple slows your iPhone on purpose.

Good to know about the battery replacement. I was dreading replacing my 6 since no way am I getting an 8 or X or 7. $79 is better than $799... I've always bought Apple refurbished phones for my family with zero problems at a fraction of cost.

Good. I figured someone would benefit from the info. Apple's done a poor job in communicating this issue IMO and I'm the biggest fanboi I know.
