Well after replacing my Android Tablet with a IPad Air 2. I’m really enjoying the Ios experience.
Would it be worth trading in my S9 and replacing it with the IPhone X or Xr?
My Mum has a IPhone 7 and its still as as the day she got it, whereas the Android devices have slowed down significantly after 15 months.
I guess it depends on whether you have invested money into the Android marketplace - as you won't be able to take those paid apps over to Apple's platform. If you really like the iOS experience and aren't invested in Android - then you've got nothing to lose really.
Touching on the slow down you mention - I have yet to see anything like that in either an Android or Apple phone, over the last ~12 years of using smart phones, so I wouldn't use that as an excuse to jump ship - certainly as you have an S9; a fairly new, and still extremely powerful Android phone. Most of the 'slow down' I hear people talk about, is probably where they have used newer (faster) devices, in work or whatnot, and then start to get used to that new level of performance; so start to feel their device is slowing down. Rubbish apps can also impact performance, but I am personally dubious that any modern tech will experience significant slow downs - unless there is a fault.
It's entirely your choice though - if you have the money/contract freedom to switch - then go for it; but make sure that you invest in as much capacity as you can afford - Apple devices [used to] run out of space rapidly, and you would be stuck having to delete you files to get the thing to work again. Android phones typically have SD card expansion - and some (probably not your S9) will allow you to move core apps off of the main storage.
