Conclusion & End Remarks

The Xiaomi Mi9 was one of the missing flagship phones that was eager to cover this year but hadn’t had the chance to till now. Overall, I’m glad to have been able to test the device even though it’s later in the year, and it did reveal it’s still quite the good overall package and offers excellent value.

Design-wise, I actually do love the Mi9 simply because of its ergonomics that I find impeccable and extremely comfortable. Even though the phone’s screen is among the larger diameters at 6.39”, it very much feels like a smaller phone thanks to its very thin side-frame. The device is also relatively light for its size, comparable with what Samsung is able to offer in terms of size-weight ratio.

The display is very good and on par of what you’d expect of an AMOLED screen, offering excellent contrast and Xiaomi allows the panel to also get plenty bright. Colour calibration is also quite acceptable, being not great, but terrible. It should very much satisfy the vast majority of users.

Performance of the Mi9 is excellent thanks to the Snapdragon 855 SoC the company chose to employ in the phone. CPU and GPU performance that the phone is able to deliver is just beyond anything else that’s currently available in its price class, very much a Xiaomi tradition.

Battery life of the Mi9 is relatively average – the comparatively smaller 3300mAh battery capacity of the phone loses out to other devices which are in the 4000mAh class. On the other hand, Xiaomi also offers wireless charging in the Mi9, which is a bonus for quickly topping off every now and then, and the phone package bundles in an 18W charger.

In terms of cameras, the Xiaomi Mi9 surely offers a good amount versatility thanks to its triple-camera setup.

I found Xiaomi’s post-processing to be among one of the better ones out there, producing some of the best results out of the IMX586 sensor amongst the countless vendors and devices out there with the similar hardware setup. The wide-angle and zoom modules were also extremely competitive in daylight, producing sharp photos with competitive compositions.

Unfortunately, where the cameras completely fall apart in the Mi9 is low-light photography and video. The lack of OIS on even the main sensor of the phone is deadly, and the cameras just aren’t able to produce useable results. Xiaomi offers a Night Mode to help along with things and it does improve the situation, however the phone still remains plainly uncompetitive in terms of picture quality.

Other compromises of the Mi9 is in the audio department, although with a similar earpiece speaker setup as the OnePlus 7, the Mi9 lacks stereo playback and just has to rely on the bottom speaker.

Xiaomi is able to offer the Mi9 at such a low price thanks to some partnerships and advertising, in this case MIUI here and there can show ads, particularly in the post-installation screens of applications. Personally, I couldn’t care less about these ads as the rest of the UI experience was seamless – but potential buyers should be aware of them.

Overall, I think the Xiaomi Mi9 is a fantastic device with the only real and possible deal-breaking compromise being its low-light photography. I hope for the next generation Xiaomi doesn’t make this compromise again, even if the phone costs 10$/€ more.

At 400€ the phone still offers incredible value, and I think any potential buyer will be happy with their purchase.

    Who you calling troll, stating facts.
  • Korguz - Saturday, September 14, 2019 - link

    then back up your "facts " with proof, seems even Andrei doubts these " facts " of yours :
    " I accept your challenge. You play the AnTuTu card, you lose. "
    and from Ian as well : " AnTuTu is the laughing stock of benchmarks. The minute someone tries to justify their position with an AnTuTu score, you know not to take them seriously. "

    Yeah I'm not sure this troll even read the article, so I think asking for facts likely a bit of a tough ask. At all conclusion is that perf seems fine vs other devices.

    One point - I've seen discussed elsewhere that the 9T pro has an inferior thermal solution that the 9T so perf may not be quite as good. Jonathan.

    "AnandTech has reviewed this product as part of a paid partnership with Qualcomm."

    Is someone at AT permitted to go into greater detail about the nature of the partnership? What obligations is AT under? What are Qualcomm's expectations?

    We'll be posting three more S855 device reviews in the next 2 weeks, other than that and the inclusion of the benchmark setup (AI), there is no effect on the content of the articles posted and I'm writing the reviews independently as I would have in a normal scenario.

    Cool, thanks! That makes sense.

    The big problem here is that it takes up your bandwidth to look on other more interesting devices like the exynos 9825. Qualcomm is requesting these reviews for press, nothing else. But here at AT we care more about tech, so I think that in the future it is best to refuse these kinda of requests and sponsorships and do your own reviews

    ?? but then who will pay them to keep the site running since everyone uses adblocker?
  • A5 - Friday, September 13, 2019 - link

    I've read literally nothing that indicated that the Exynos 9825 holds anything of significant interest to AT readers over Exynos 9820. Why do you keep asking about it?
  • Andrei Frumusanu - Friday, September 13, 2019 - link

    It's an interesting academic view on the 7EUV process node, but other than that yes it holds very little value currently.
