I did not see any loss of performance going from iOS 17 to 18. I would say in some ways it feels a little smoother, but that could be new and shiny placebo. More importantly my battery life remains consistent. I am quite pleased with everything performance wise, but obviously everyone’s experience will differ based on their needs and perceptions, as well as what is on their phones and how they use it. Though I no longer beta test, I am a day one updater. I can’t remember iOS 16 performance wise LOL.I’ve been hanging at 86% for quite some time now too on my 14 pro. I’m still on iOS 16.7.2. How is iOS 18? Still fast? I’m afraid to lose my launch software’s speed!
