In some cases, Apple will go so far as to inject code into your phone to begin to break down after the initial warranty is up
Is it a rumour or a fact ?
I always thought that the decline in performance in the devices over the years was a result of Moore's Law,
intentionally protracted integrating computationally heavy features into iOS,
but also necessary to have a homogeneous system & SDKs.
`Injecting code` seems like a bit extreme to me xD
Would still prefer iOS to the confusion of the Android code: elegance vs natural selection.
Being sure to receive updates is also in favour of iPhone and a consequence of the design of the device ecosystem.
Since Google Pixel is branded(TM), it's still a viable option in this sense.
