I changed this Android setting to instantly double my phone speed (and it works on any model)

Now that you’ve cracked the code to get into the Developer options, you’ll be presented with a long list of settings, toggles, and switches. Don’t be intimidated; we’re only here for one thing, and that’s the “Drawing” section. Scroll down the list until you find it.

From there, you’ll see three animation scale settings:

1. Window animation scale: The speed of apps and window pop-ups.
2. Transition animation scale: The speed of moving between home screen panels and within apps.
3. Animator duration scale: The speed of general UI animations, such as opening and closing apps, unlocking the phone, etc.

Tap on each one and change the scale rating from 1x (default) down to .5x. The lower the number, the faster the time it takes for the animation to perform. 

If you don’t want any animations on your phone at all, you can also set the value to “off”.
