Guess I'm not upgrading my iPhone 6 to iOS 11. Just saw a bunch of comparison videos 10.3.3 vs 11 and clearly 11 has some noticeable sluggish here and there, especially on the camera app wich is what I use the most and the fact it drains battery faster than 10.3.3 is a deal breaker to me. Too bad I'm broke at the moment to upgrade to a new model of iPhone. Hope this can be improved on future updates but not holding my breath anymore
