Display OnePlus 7 Pro 90 Hz automatically switches to 60 Hz

The recently announced OnePlus 7 Pro smartphone continues to be at the center of discussions on mobile forums and

Internet media pages. In addition to possible problems with the phone and negative reviews about its dimensions, one more nuance is now known, which concerns its main feature — display.

As you know, OnePlus 7 Pro became the firsta smartphone whose display supports a 90 Hz refresh rate. What does such an ultra-fast frequency provide, you ask… Smoother animation, stunning effect when scrolling content and while interacting with the device. Today you rarely see such a feature in phones.

However, there is one caveat.As it turns out, the user will not be able to constantly enjoy 90Hz even if the 90Hz option is activated in Settings. In fact, the manufacturer took care of automatically selecting the desired refresh rate — when to use 60 Hz and when — up to 90 Hz.

OnePlus limits screen updatesup to 60 Hz when using the Phone app, YouTube app, camera, or any large-scale game. Because in these scenarios you do not need a high refresh rate. The highest frame rate that YouTube can use is 60 frames per second, and most games have a maximum frequency of 60 frames per second. The camera also records at speeds from 30 to 60 frames per second. OnePlus considered it appropriate to adjust the refresh rate in these cases in order to reduce the load on the battery and the equipment as a whole.

However, there is a hidden mode thatwill force the display to work with a refresh rate of 90 Hz. And you can turn it on in an unconventional way. To do this, you will need to connect your phone to your PC using a cable and use ADB commands.

Once activated, both switches are in Settings.Screen refresh rates will be disabled and the summary text in Display Settings will display "60Hz". But this is just a bug, as OxygenOS doesn't expect users to be able to select this hidden refresh rate mode. To switch back to one of the officially supported modes, you just need to change the switch in the display settings.

The manufacturer itself does not recommend using 90Hz all the time, as it increases battery usage. Trust the automatic adjustment of the desired frequency!
