System Performance

Following our Snapdragon 855 device overview, we should be relatively familiar with how the Xiaomi Mi9 performs. The chipset is by now a very well known component and various devices with the silicon will only ever differ by the software stack implementation by the vendor.

In Xiaomi’s case in the Mi9, I didn’t see anything particularly standing out for the phone, performing quite well but also not particularly distinguishing itself as being among the best nor worst performers amongst its Snapdragon 855 siblings.

Unfortunately, in the default mode in PCMark, the Reno 10x didn’t quite keep up with some other Snapdragon 855 devices, ending with actually some of the worst scores amongst its competition, something particularly visible in the web browsing and writing sub-tests. Here it looks like Oppo chose to tune the software quite conservatively compared to other vendors.

In the JS browser performance tests, we also find that the Reno 10x lands amongst the lower performance devices, although the absolute differences here are more minor.

In my subjective experience with the phone, it’s again much like on other Snapdragon 855 phones: Whilst the Oppo does feel ever so slightly slower than other flagship devices, the difference isn’t all that big and it’s still a plenty fast phone. I suppose it’s a balance Oppo chose to make in order to improve the battery efficiency of the phone, which we’ll get back to in a later section.

    Page1: "The display is an AMOLED panel featuring a 2340 x 1080 resolution and comes at a rather large diameter of 6.6”. " diameter should be diagonal. Reply

    "Oppo alleviates this concern by including a small raised nub below the cameras, causing the phone to never actually be flush against any surfaces and thus vastly reducing possible scratches of the back glass near the cameras."

    Does this mean that if you set it down on the table and try to use it you're going to have a wobbly bad time?

    It wobbles if you press the top of the screen, the bottom 2/3rds are stable. Reply

    Since almost all flagship phones have night mode, can we do a shoot out and provide us strength and weakness plus overall winner. I guess best time would be when Pixel 4 is released. Reply

    -Needs front stereo speakers which allows you to hear youtube videos, movies, emulator games, camera videos, etc in full volume.
    -And wireless charging which is extremely useful, no port wear, start charging faster/with one hand, magnetic charging mount in the car.. Still use it all the time on my Nexus 5. Wireless charging pad cost me $3.00 on ebay.
    -The missing 3.5 headphone jack is not really ideal..

    I’m not convinced that a pop up camera is a good idea, particularly if all that mechanics and electronic is there to just eliminate a hole in the screen.

    Notice that there’s no water and dust rating. That’s because it’s almost impossible to keep water and dust out of the slot. I can see grit from wind picking it up, being deposited inside that slot, eventually scratching the lenses and eventually causing the module to grind to a halt. Moisture too. It will remain in the slot for some time, causing problems.

    Thanks Andrei! Agree with you and others here that the pop up camera is a gimmick that adds complexity and weight, not to mention anything that moves is another thing that can break. Too bad Oppo didn't put the extra weight and complexity to make a really good periscope style optical zoom camera - if done correctly, they can be spectacular.
    @Andrei: Lastly, one question and request: what about the call quality of this and other phones? Please add a sentence or two on this to your reviews, good call quality is a non-negotiable for me and probably many others.
    I do use my smartphone as my main phone, and had to bench/retire my Xiaomi Mi Max 3 phone due to really horrible call quality (on both sides, got many complaints over poor voice quality). I loved many aspects of that phone, especially the big screen and battery, but it was basically useless as a daily driver. Now back to an older LG phone, not as good otherwise, but I can make and receive clear phonecalls.

    I believe the top of page 2 comes from a previous review and you need to edit it for the Oppo. Reply

    I have no idea how your Oppo10x zooms scores so low in benchmarks. My UK version scores very high in all benchmark scores. Antutu score of 370k, geekbench 4score 3514/11314 . Pcmark work2 performance score is 10564 Reply
