You sure can't do it with an iphone. I own one an iphone 15. Was beautiful when new. Even now it has started on the path of suck. Apple have "upgraded" it to have a more frustrating touchscreen because they clearly think I should give them more money to keep the experience I bought. They are not cheap.
Apple are the absolute kings of planned obsolescence.
Zealots going for silent downvotws because there is no case they can make to the contrary. Not what downvotes are for, says HN but we're all used to HN being used like this by now.
It is ridiculous to suggest otherwise. Go pick up an iphone 6 and try to do anything with it and then tell me that is how awful the ui was when it was released to apple orchestrated media fanfare. Or any older ipad. Imagine if that ui extreme sluggishness, random delay and the button moving just as you hit it is what they were showing off at launch. The laughter would have haunted them all the way to the accountants telling them their options were now worthless.
Apple latency degradation is not worth discussing with anyone who says it isn't happening. You can't solve whatever issues they have.
