iPhone 6 Poor performance after upgrade to IOS 11

Apple, I have been a loyal customer for many years, 1980 (Apple II) onwards!

I currently have 4 Macbooks in the family, 4 iPads, 4 iPhones and an iMac.

A technology refresh is pending on some of these devices, probably next year.

The ONLY differentiator between Apple and others, is top quality, secure, products that last forever and work together and I, together with millions of others, have been prepared to pay a premium for that.

If you think I will be bullied into upgrading all of the iPhones and iPads because of the poor performance, battery life, security and stability on IOS 11, you are badly mistaken.

I will move to Android and Windows and never come back. Fix IT !!!
