Why is my iPhone 6+ is slow since the last 2 updates

I bought my phone for 1000$ 3 years ago. I was very satisfied up to the last 2 updates. It becomes slow like a turtle. Why updating the iOS for slowing my phone and making it obsolete. I’m a big apple fan, but i am very disappointed by your politics to force Us to update a software that makes our phone obsolete.

Next time, i will think twice before buying an iphone. When I bought my iPhone I expected to have it for at least 6 years. Very disappointed by your attitude. I don’t have the budget to spend 1000$ per 3 year period for a phone (333$ per year).

At least give us the chance to choose not to update the iOS or to return the old version if not satisfied.

I’m pretty sure that I’m not the first customer to complain about that issue. Better for you to listen to your customers.
