I'm especially referring to 6s owners. Mine got quite slow, and no, it's not from the animations, after updating to iOS 11. TBH, it was also slow 1-2 months before that but it's really noticeable on iOS 11. There are many articles about Apple slowing down their older devices so the sales go up. I personally kinda knew that was true but never cared because I didn't have issues when switching from iOS 9 to iOS 10. Another thing is my battery seems to drain faster. I'm actually using my replaced 6s because the first one was from the defected batch. Any feedback?
