1. almost every generation has some kind of hardware defect that you only find out later that lots of people report in enthusiast forums. Be it the loading cable, display bending, weird issues around refresh rate straining your eyes.. it never ends. And no, the hardware doesn't even feel better than the competition anymore. I had the iphone 13 in my hands and it felt like any cheap plastic phone.
2. The UI is horrible, the false perception of iOS being "simple" is perhaps the biggest marketing success in human history. I had an iPhone 13 for a few hours and there were already countless things I found incomprehensible. E.g Undiscoverable gestures or extremely hard to achieve gesture to swipe up to remove an opened app. For one ui menu on the right middle side I had to press part of the hardware button on the right (what on earth, a hardware button to activate a touch ui!). Since when is the point of using a touch device to: ignore the touch interface and instead use a hardware button. Not even considering yet the weird annoying popup ui in the first place, why would you ever put something like that on the middle of your screen.
3. scrolling is slower, they have some kind of terrible human-like algorithm where you have to gear up the scroll speed as if you're manually accelerating a dial every time you want to scroll down. This is why they had to invent all these little tricks to scroll back up to the top of a page with a shortcut. Scrolling is just too slow, on huge pages it's fingerhurting work to get to the bottom.
4. The notch is objectively terrible, it was never good, it was never acceptable to put camera holes or notches into the display but the notch is the worst, most biggest affront to visual consistency. It almost has comical qualities, "oh yes, please put a huge black block directly into my visual field and make it so I am forced to look at it, I can't even install an app to hide it".
5. The amount of popups when I open any kind of app or the appstore is incredible. I think I had at least 4 consecutive popups before it lets me do anything.
6. The prices are a riot, it's a designer luxury item. I guess in the US the prices seem somewhat acceptable but anywhere else in the world the value for this phone does not match the money you pay for it.
7. [insert here every other criticism, e.g about iTunes being required or any other of the dozens and dozens of legitimate problems]
This list is nowhere near complete. Meanwhile when I use my Android, my only complaint is that Samsung installed some default apps I don't want. That's literally it. Everything else works fine for me. I had an iphone 5s for years, while I was using it I liked it but nowadays when I have a comparison with a fluid, new android phone it cannot compete. To me it is clear that the success of Apple is a psychological success of two things mixed together: speed and beauty. The ui is always fast, therefore there is a false impression that it's simple and good. Beauty likewise gives a false impression that the ui is good in a general sense when in reality it's not better.
