The recently announced OnePlus 7 Pro smartphone continues to be at the center of discussions in mobile forums and
As you know, the OnePlus 7 Pro is the firsta smartphone whose display supports a refresh rate of 90 Hz. What gives such an ultra-fast frequency, you ask ... A smoother animation, a stunning effect when scrolling content and while interacting with the device. To date, such a chip is rarely seen in the phones.
However, there is one nuance. As it turned out, the user will not be able to constantly enjoy 90 Hz, even if the 90 Hz option is activated in Settings. In fact, the manufacturer took care of the automatic selection of 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 thatforce 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 the phone to the PC with a cable and use the ADB commands.
adb shell settings put global oneplus_screen_refresh_rate 0
After activation, both switches in the settingsscreen refresh rates will be disabled, and the text of the parameter summary in the display settings will display “60 Hz”. But this is just a mistake, because OxygenOS does not assume that users will be able to select this hidden mode of update frequency. To return 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 90 Hz all the time as the use of the battery increases. Trust the automatic adjustment of the desired frequency!
