System Performance

One of the key aspects of the new OnePlus 7 Pro is its promised performance. OnePlus now for a few generations has made a large focus on the performance of their devices, opting to go the extra mile to optimise the software experience of their devices and the OS software. The new 7 Pro promises to thus to differentiate itself from other Snapdragon 855 devices.

Another way that the performance of the OnePlus 7 Pro should be much improved compared to the competition is the inclusion of UFS 3.0 storage as well as the new 90Hz display. Admittedly our testing setup for NAND is currently inadequate to fully test the storage speed, however the 90Hz refresh rate does have some immediate effects on some benchmarks, in particular our favourite, PCMark.

PCMark Work 2.0 - Web Browsing 2.0

In PCMark’s web browsing test, the OnePlus 7 Pro showcases some larger score discrepancy between its 60 and 90Hz modes. What is interesting is that the 60Hz score is unusually low, performing quite a lot worse than what we saw from other Snapdragon 855 devices who are 60Hz themselves as well. The 90Hz mode does up the score notably, however it still slightly lags behind the Galaxy S10+ as well as all other Kirin 980 powered devices.

PCMark Work 2.0 - Video Editing

The video editing score is in line with the majority of the pack, but again the OP7Pro is lagging behind the Samsung S10+ with the Snapdragon 855.

PCMark Work 2.0 - Writing 2.0

It’s in the writing sub-test, arguably the single most important workload of PCMark where the OnePlus 7 Pro manages to distinguish itself more compared to other devices. Here both in 60 and 90Hz modes the device manages to take the top spots in the charts.

PCMark Work 2.0 - Photo Editing 2.0

The photo editing workload is also an important indicator of general device snappiness. Here the OP7Pro again beats the competition from Samsung and LG with the same SoC. I think it’s possible that OnePlus has better and more optimised OS libraries and this is why this is seen as a performance advantage compared to the competition.

PCMark Work 2.0 - Data Manipulation

The data manipulation score again has a notable difference between the 90Hz and 60Hz modes, but much like the web-browsing test we’re again seeing some oddly low performance of the 60Hz mode, much below that of other Snapdragon 855 devices.

PCMark Work 2.0 - Performance

Finally the end-score of the OnePlus 7 Pro ends up just shy of the Snapdragon Galaxy S10+, losing some yet winning others. The 60Hz mode does have an effect of the score and in this mode the OP7Pro loses a few hundred points.

Browser JS Benchmarks

Speedometer 2.0 - OS WebView WebXPRT 3 - OS WebView

In the Javascript web-browsing benchmarks the OP7Pro is relatively in line with the LG G8. The odd thing here again is that Samsung’s Galaxy S10+ with the same chip offers a quite different performance fingerprint. This is particularly visible in WebXPRT where it has a lead over the OP7Pro. It’s to be noted that in the web benchmarks I haven’t seen any difference in scoring whether the device was in 60 or 90Hz display modes.

Device Performance Conclusion – A Lot Not Covered By Benchmarks

While the OP7Pro performed quite well in our system benchmark suite, there’s a few aspects of the phone that unfortunately aren’t really covered. One such things is the NAND storage and the experience that the 90Hz mode gives.

In terms of the new UFS 3.0 storage, its addition to the phone was something that I immediately noticed in regards to application installation speeds. Here the OP7Pro was significantly faster than any other Android device I’ve had before, shaving off significant chunks off of installation times.

Another subjective aspect that is hard to objectively convey in benchmark numbers is simply the vastly improved UI fluidity brought forth by the 90Hz refresh rate of the phone. Any PC user with a higher refresh rate monitor will know what an immense difference this makes compared to the more traditional 60Hz. The very first time I held the OP7Pro at our pre-briefing I immediately saw the massive difference this makes to the fluidity of scrolling and very much knew that this would be the killer feature of the phone, no matter how all other aspects would end up.

While in terms of UI snappiness, the OnePlus 7 Pro isn’t any faster than say Samsung’s S10, its fluidity just stands out as something beyond any other current device (Asus Rog Phone & Razer phones aside). OnePlus’ combination of high-refresh rate on an OLED screen makes for an incredible selling point.

While the 90Hz is fantastic, I have some serious doubts about the 60Hz mode of the phone and whatever OnePlus did to the software stack in terms of implementing this. For some odd reason, it makes things notably slower, and I’m not just talking about simply there being less frames, but actual reduced responsiveness and an impression of more sluggishness and jank. In fact, in 60Hz mode the phone feels notably more sluggish than the Galaxy S10, when in theory it should have been equal. The fact that the OnePlus 7 Pro somewhat performs more similar to the G8 in some web benchmarks has me suspect it actually has similar BSP performance issues, and the 90Hz mode somehow just counter-acts these negatives. It’s really odd.

That being said, just stick with the 90Hz mode and you’ll have a fantastic experience beyond that of any other phone out in the market right now.

    Correct and at the same time wrong. Yes, heat degrades batteries faster, but it's not the only factor. How fast you put charge in the battery also leads to degradation. Enough materials on the web to explain in details - google it. Reply

    I bought that phone, tested it for about 30 minutes, then sent it back.
    The curved display is just not for me, especially because they made it so much more curved than on Samsung phones.
    1. Things tend to "fall off" the edges and give the impression that the screen is too narrow, it's annoying.
    2. Colors are shifted on the edges, especially if you don't hold the phone exactly parallel to your eyes. White appears grayish green.
    3. Glare is more frequent as light can be reflected not only from the front of the display, but also from its sides.

    What a waste.

    I'll just add that I don't understand how most reviewers overlooked these problems. Is it just me? Reply

    Nope, I hate pretty much all curves besides 2.5D since it makes it easier to grip, but it doesn't mean the image display itself has to be curved. Reply

    It is good to know that this phone does come with compromises built in, unlike some other sites that make you believe that this phone (like the phone released a week ago) is going to change the whole industry, just because it is cheap.

    Some points
    1. Do you have some power measurements at peak sustained power or it has been done before ?
    -> Am I the only one who thinks that increasing performance on mobile, by implementing heat pipes, coper plates and fans, and run it all as hot as possible is just ridiculous ?!?
    2. This device supposedly comes without display lamination ! Can someone confirm/deny ? OLED's will get destroyed when exposed to humidity.
    3. Regarding high refresh rates, we really need an Apple implementation- custom T-CON, GPU regulating the refresh and continuously variable refresh rate in a wide range (like 24-120 fps) to save energy. To my knowledge this is possible thanks to IGZO backplane iPad pro uses. And no OLED panel is using that yet. Is there a compatibility problem ?

    I could not care less about the camera and the rest looks like an amazing package(bar lack of 3.5mm), but this is a skip for me because WiFi 6 is on the horizon and I'm going all in when it arrives. Reply

    If I was looking for a new phone right now, this would be the obvious one (I love my OnePlus 5T), but it looks like the price has creeped up to near top-end pricing. Not only that, but OnePlus seems to realize that too with the OnePlus 7 and 7 Pro. Unfortunately the 7 is not available in my market, which is very frustrating. I'd have to pay for a battery-sapping screen and 2 additional novelty cameras that I'd never use.

    All in, if I broke my current phone tomorrow I'd have to go on a hunt for my new phone instead of just going back to OnePlus because this phone is just too expensive and it's only too expensive because of those gimmicks.

    >>This is not only because it’s OnePlus’ first ever 1440p screen which is a great improvement in sharpness,

    Can you tell the difference between 1080p and 1440p on a 6" device?

    Yes, very much. Reply

    Can I flash this damn thing and run WIndows ARM on it? Reply
