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.

    I don't think I've ever thought about or ever noticed phone weights. Size and bulk? Yes. Weight? Never.

    It’s one of these things that you don’t notice until you pick up a phone that passes the point of being too heavy.
    I agree with the op, I hate the feeling of having a brick in my jacket pocket.

    That's a good point. If I still had to wear a suit everyday then the weight would be problematic.

    For those that don't have to wear suits, I actually like the slightly heavier phones, though anything more than 200g is still too much even for jean pockets.

    Fuly agree, I find my Note 8 at 195 gram too heavy. I never felt the same in regard to my S7 Edge at 157 gram. And I find the Nokia 3310 at 85 gram a bit too flimsy instead. Depending on the individual of course, but to me a weight of 120-140 seem perfect. The S4 for example is 130 gram. Not feeling flimsy, still very thin and light.

    The entire design trend of phones needs a rethink. At least one major OEM should put things in reverse and do things like a *plastic* or *metal* back, bezels on the top and bottom (with stereo speakers for the occasional time when you have to use your phones sound), and a SLIGHTLY smaller screen. As far as a headphone jack, I'd rather just see a dongle in the box TBH. The whole headphone jack thing is overblown. Pumping audio through the USB-Type C port means you get a clean digital signal, making it possible to do things like optical out, etc. Combine that with a built in amp on the phone (along with the 'quad DAC' that some LG phones have) and you get a nice clean signal that can either be converted to a headphone jack or hooked up to a soundbar or surround sound system.

    I'd also like to see micro SD cards return and have a storage manager built into the system that combines internal and external storage. Encrypt it if you want, but as quickly as prices have fallen (I just bought 4 128 GB microSD cards for $15...and they are REAL. Ran a tester on them.), External storage will be the way to go when you run out of space. I'd also like to see an AOSP style release without vendor junkware.

    The problem is I wouldn't pay a premium for those features. Such a phone would be worth about $499 if it had 4 GB of RAM and a Snapdragon 855 combined with a 2560x1440 AMOLED screen.

    I agree with a lot of that, but definitely not the headphone jack port. It should stay, as as a connector it is more durable when in use because it can rotate. We're finding out that many USB C ports are not that much better than microUSB ports in terms of durability.
    Besides, all headphones end up analogue.

    It's not like the USB C port would suddenly lose audio transmission capability.

    They could easily dispense of some weight by using plastic.
  • drexnx - Wednesday, September 18, 2019 - link

    all that heftiness and chunk and they still couldn't find room for a 3.5mm jack?

    "Low-light Conclusion - Terrible


    Overall, the Reno 10x does adequately in low-light, which is something great to see as it means that future devices from the vendor will only continue to iterate and improve upon the current results."

    So.. um.. which is it?
