The OnePlus 7 Pro's 90 Hz screen will sometimes silently switch down to 60 Hz

But, wouldn't you know it, it seems you won't get to enjoy 90 Hz at all times even if you go into Settings and make sure that the 90 Hz option is checked. In fact, internally, OnePlus calls it "Auto 90 Hz" since the phone intelligently chooses when to use 60 Hz and when to go up to 90 Hz.
Put down the pitchforks, there's good reasoning behind this!
Reportedly, OnePlus will limit your display's refresh to 60 Hz when using the Phone app, the YouTube app, the Camera, or any large scale game. Because, in these scenarios, you don't really need the high refresh rate. The highest frame rate a YouTube can go to is 60 FPS, and most games are coded around 60 FPS as the ceiling. The Camera is also all about recording at 30 to 60 FPS. OnePlus found it appropriate to throttle the refresh rate in those instances just to shave down some of the battery usage and lighten the load for the hardware in general.
However, some browsers may also not run at 90 Hz, which may be a compatibility issue... and that's not cool.
You can enable "True 90 Hz" mode, which will force the display to stay at the higher refresh rate at all times. To do so, you need to connect your phone to the PC via cable and feel comfortable enough with running an ADB command. You can find all the info in the XDA report.

Very logical decisions. Why refresh at 90 frames and the content refreshes at 60?

This is like asking for a display with 400 ppi when the average healthy human eye sees no more than 300 ppi.

That is only true for normal viewing distances, and for non-PenTile displays. You'll spot the difference the moment you take your phone closer to your eyes than you're supposed to. Mobile VR also needs the high resolution. A PenTile display has only two glowing points per pixel, so it takes a higher resolution to mask the effect.

Is that means screen throttle?

Something tells me this soo much noticeably smoother than 60hz is more placebo effect more than anything. If this is true that it's switched to and fro in certain applications and people were not made aware of it til this article, it only supports the claim.
