Refresh rate issue. Constant 120 hz via OnePlus 9 Pro

    See I have spent almost minimum 4-5 mins on each screen and just see it stays constant 120 hz on these screens. The main reason your battery is draining faster is because oneplus has not optimized screen refresh rate.
    Only time it goes from 120 to 60hz is when i open keyboard for typing.

    This is why oneplus 9 pro fails with battery expectations.

    Yes the issue has been there since Android 10 and not fixed till date, same is the issue with other phone like 7 pro , 7T and now 9 . I have talked about this issue since 6 months ago still not fixed.

    The developer setting option is not capable of showing the true refresh rate of the dynamic refresh rate feature. It shows only the mode it is using.
    If you to control 60 or 120 beyond the automatic options you can use the app AutoHz.

    I disagree with this fact you stated. There is a color shit you can see if you look clearly. In my 7T in 90 Hz I can see the tint issue but not in 60 Hz , while using the 90 Hz when I use keyboard the tint issue goes away and refresh rate is shown 60 . Your might be talking about LTPO technology's dynamic refresh rate which is not the argument about for this case since 7T doesn't have dynamic refresh rate . This is a software issue, the best option is to report in feedback section.

    I responded to the tread owner (but could not quote the post due to using the app). That user is using a 9 Pro with LTPO. In that case 120 Hz is not necessarily always 120 Hz even if the monitor shows it (it only shows the mode it is in, not the real Hz).
    On a 9 Pro the 60 Hz mode may still be used in some situations. But in some cases 120 Hz could actually be more efficient since it can go below 60 Hz.
