It's not just you. Take a look at the google trends data for "iphone slow": https://trends.google.com/trends/explore?date=all&q=iphone%20slow https://trends.goo

  That chart would seem to indicate that every release of iOS (usually in September) results in some people experiencing their phone as slow. Except, strangely, for iOS 10 last year, which had an extremely minor bump in comparison to the rest. Anyone know why? Was iOS 10 the "Snow Leopard of iOS releases", with more of a performance focus?

    It is my understanding (possibly mistaken?), that after a major upgrade iOS reindexes spotlight metadata. This is done in the background, but drains battery and kind of makes the device perform a bit more slowly. Same day right after an upgrade, my phone tends to be a bit pokey and the battery drains pretty quickly. Next day after an upgrade, my phone usually "feels" fine again and battery life is back to normal.

  I'm not sure that proves the iPhone gets slower with each update. Whenever I announce an update my users suddenly become hyper-sensitive and start reporting bugs that have been present for weeks/months. I wouldn't be surprised if there's a similar effect here.
