Tens of millions of old iPhone users were left in the dark why all of a sudden the phone was slowing down to the point where it was becoming unusable. Millions of people probably spent hundreds of dollars otherwise they wouldn't need to spend if they know this was something they can fix with a new battery.
I personally have been using iPhone 6 for 3 years until this CPU-Battery disaster struck. So I ended up buying an Android phone. I love my Android phone now, but it's still money I wouldn't have had to spend.
This is a huge scandal. I like the response by Apple, but it's too late and millions of people already spent money they could've avoided spending. Good bye iPhone. I won't be coming back.
