Pixel 4 has had to restrict brightness and refresh rate to make up for the smaller battery capacity compared to pixel 3.

So you get a phone advertised as 90hz refresh rate, but does 60 most of the time and only hits 90 when the screen is at a specific brightness.

The max brightness had to be capped at about half of what a similar Samsung can do. Deep inside the kernel there is a disabled high brightness mode, meaning without root access and some hacks, you can’t even get the phone it hit its physical maximum. Leading users to complain about the phone screen being too dark.

What a heap of utter shit.
