The scrolling on the OnePlus 10 Pro is bad, and OnePlus should feel bad
The OnePlus 10 Professional has a serious scrolling drawback, and it makes the telephone borderline unusable.
To place it merely, the telephone reveals large stutters and delays when scrolling in sure apps. My understanding is that that is led to by the best way OnePlus has configured the dynamic refresh charge system on the show.
Earlier than going any additional, here’s a demonstration of how this works. First, let me attempt scrolling by way of a mean Instagram timeline, which over the course of time has come to be populated with extra movies than pictures. The importance of this shall be defined later.
Now this is scrolling in Flamingo, a third-party Twitter app. Whereas Flamingo is now not offered on the Play Retailer, it continues to be up to date.
The scrolling within the two apps is completely different however noteworthy both approach. The necessary factor to note, nonetheless, is the little refresh charge counter within the prime left nook of the telephone’s display screen.
To know what is occurring, you must understand how the show is configured to work. The utmost 120Hz refresh charge is not everlasting and the show can clock all the way down to a number of different values relying upon what is occurring on the display screen. A few of the values I famous embody 90Hz, 60Hz, 30Hz, 10Hz, 5Hz, and even 1Hz. The rationale to ramp down the refresh charge is just to avoid wasting energy.
In comparison with earlier OnePlus telephones, the OnePlus 10 Professional is extraordinarily aggressive in relation to lowering its refresh charge. Sadly, it additionally tends to do that even when it is not alleged to.
One of many examples we gave in our assessment is when you could have Apple Music open and the lyrics are scrolling mechanically on the display screen. You are not manually interacting with the display screen so it by no means goes as much as the total 120Hz refresh charge. Nevertheless, as a result of the telephone ramps all the way down to an aggressive 30Hz, the lyrics auto-scrolling look noticeably uneven. The telephone does appear considerably conscious of the movement on the display screen and may go as much as 60Hz because the textual content scrolls up nevertheless it would not do that each time and even when it does, 60Hz nonetheless seems notably worse than 120Hz.
Nevertheless, the more serious offenders are apps you actively work together with. Instagram is probably the most effective instance of this; the app has static photos and video components. The software program is designed to ramp down the refresh charge when it detects a video on display screen to both 30Hz or 60Hz relying on the video (OnePlus is unaware of 24/48fps and 25/50fps video, however that could be a dialogue for an additional day).
Now each time you scroll by way of your timeline and a video seems, the show immediately drops all the way down to 60Hz and even 30Hz in a knee-jerk response. This occurs if you are nonetheless actively interacting with the machine, which makes the complete scrolling expertise comically unhealthy.
The 60fps video above ought to offer you some thought of that however it could possibly’t fairly seize what it feels wish to be whiplashed between 120Hz, 60Hz, and even 30Hz backwards and forwards inside one single scroll of your finger. And it is the switching that causes probably the most drawback; whereas 60Hz by itself is not ultimate, a constant 60Hz is completely usable. However being made to ping pong between 60Hz and 120Hz as you scroll feels actually horrible and is simply not usable.
The instance with Flamingo is especially nasty. Right here, there are not any video components enjoying on display screen. Nevertheless, the telephone demonstrates a wierd rubber band impact to scrolling, the place it simply snaps backwards and forwards with a delayed response that’s onerous to clarify. That is so unhealthy you may see it even in a 30fps video. The display screen is in such a rush to drop all the way down to 1Hz that it forgets the person continues to be scrolling and in addition can not seem to ramp again up quick sufficient.
Whereas Instagram and Flamingo are two of the worst offenders I’ve come throughout, the scrolling is loads unhealthy even in different apps. The show will simply randomly stick itself in 60Hz mode for prolonged durations of time whereas scrolling by way of apps, solely to right itself after some extra scrolling. Typically it is onerous to inform what triggered the show to ramp down its refresh charge mid-use and it simply appears to have a thoughts of its personal.
I will not belabor the purpose additional as the 2 movies above are all the pieces you could see. The difficulty is that the telephone has had this drawback since we first acquired it previous to its launch, and the issue has continued by way of two subsequent software program updates (the telephone is at present on A.13). The second replace truly made it worse, particularly in Flamingo, which was largely usable earlier than. As is commonly the case, we had introduced up the difficulty with OnePlus prior to now, to not point out included it in our day 1 assessment.
That is an costly telephone and we anticipate lots higher. A difficulty like this would not be acceptable even on a price range machine so there is no motive why we should always proceed to disregard it on a flagship machine.
At this level, all we will do is concern a PSA and advocate not shopping for the telephone till this concern is mounted. The aim of that is to make sure the corporate takes discover of it and works on a repair. We are going to present an replace when that occurs. Till then, caveat emptor.
