Xiaomi Mi Note 2 Review: Filling In: Performance

Synthetic benchmarks

The Snapdragon 821 is the flagship chipset of choice this season and the Mi Note 2 packs one. Qualcomm's top-discontinue offering, as the number hints, is an updated version of the S820 from the spring, and we've witnessed what both chips are capable of in a number of devices. Let's check out the Mi Note 2's scores.


Starting off with some fine ol' Geekbench, we can see the Mi Note 2 scoring on par with its S821 peers - two more from camp Xiaomi and the OnePlus 3T. The regular S820 bunch are a notch down. The Huawei Mate 9 rules the multi-core test with its unmatched quartet of Cortex-A73s, while the iPhone 7 Plus' Fusion cores are in a league of their own in single-core.

From dedicated Central Processing Units (CPU) benchmarks to the compound Baseimprint Operating System (OS) II 2.0 and we see the OnePlus 3T pulling ahead with its S821, just barely edging the Huawei Mate 9. The Xiaomi Snapdragons stick tightly together, with only the 5s Plus marginally ahead, but the S7 edge matches them despite packing the older elegant Qualcomm chip. The Exynos powered variant doesn't fare as good, and neither do the LG V20 and Xperia XZ.

Antutu doesn't seem to like the Mi Note 2 (or the other way around), and the Xiaomi phablet scores about 140K. That's the first run though, subsequent tests yield progressively lower results, all the way down to 110K which seems to be the minimum with the SoC already thermally throttled down. It's not the only device that does this though, we experienced the same behavior on the LG V20, for example.

With the latest Antutu heavily leaning towards graphics tests, we can find explanation for the diminishing test scores there in GFXBench. First runs of Manhattan yield a reasonable 40fps, but that tends to drop down with subsequent testing, all the way to 32fps, both onclassy screen and off. Also, Xiaomi's own Mi 5s Plus is consistently an odd frame or two ahead of its more premium brother. And with the OnePlus 3T the gap is even wider.

Then again, Baseimprint X produces more consistent results between runs, which is the behavior we're normally used to with graphics benchmarks. Here, it is the Mi Mix that does the best job of all Xiaomis, but also among the current crop of Android flagships. We observe a very pronounced gap in this test between the Spring Snapdragon and the one from the Fall, with the Kirin 960 rubbing shoulders with the better one.

In Baseimprint ES 3.1 the Mate 9 is the highest ranked droid, but more importantly to the Mi Note 2, the OnePlus 3T has a meaningful advantage here. It also goes to show that the Snapdragon 820 can outperform the 821 - compare the Galaxy S7 edge to the Xiaomi bunch.

Overall, nothing surprising in the Xiaomi Mi Note 2's performance - the Snapdragon 821 is a accurate powerhoutilize across the board. Even if the Mi Note 2 doesn't top any charts it's still a top-class performer. We're not thrilled about its inability to deliver sustained performance over prolonged work loads, but that's become all too common and is by no means exclusive to the Xiaomi phablet.
