I don't think anyone intentionally wants to write slow software. What would iOS and Android developers (both app and OS) stop doing or do differently?

Stop packaging mobile JS frameworks as native "apps".

Have you heard about the new fancy framework in JS ? It emulates x86 in css, then boots Windows Vista in to execute a Visual Basic Application in containing a webView with mobile react !

It's a bit slow on loading, but after that it's really fast !

Stop making everything animated or translucent?

I'm curious why you were downvoted. I have found animations do slow down my phone. When I press the home button, as the apps fly in, I can't scroll left/right until the animation is done playing. I have reduce animations turned on (accessibility settings, I think) as it makes my phone feel a lot faster.

Also, I remember the calculator app being unreliable due to animations: https://www.macrumors.com/2017/10/24/ios-11-calculator-anima...

Is this not a legitimate problem?

I know on Android there's an option in the developer menu to double the animation speed that can make an appreciable difference. Maybe something exists on the iPhone side too

Thanks for mentioning this. I've noticed the setting before but never played around with it until now. I didn't have any performance complaints (Pixel 2 XL), but disabling animations makes (nearly†) everything feel noticeably snappier.

† The google feed seems to have a consistent lag upon switching to it from the home screen (double tap on the multitasking button is normal) that the animations hide. It loads somewhere around 150ms slower than most applications, even taking longer than the first launch for unused apps.
