Performance & Gaming

Obviously, one of the main highlight of the Mi 9 is its performance. This is the first ever smartphone in Malaysia that runs on the latest Qualcomm Snapdragon 855 chipset. Spoiler alert: it wrecks every other chipset in the market today.

The Xiaomi Mi 9 that we are reviewing comes with these core specs:

  • 6.39-inch Super AMOLED display with 2340×1080 pixels in resolution
    • Waterdrop notch
  • Qualcomm Snapdragon 855 chipset (7nm fabrication)
    • 1x Kryo 485 @ 2.84GHz
    • 3x Kryo 485 @ 2.42GHz
    • 4x Kryo 485 @ 1.80GHz
    • Adreno 640 GPU with 384 ALUs
  • 66GB LPDDR4X RAM
  • 128GB UFS 2.1 storage (no microSD card slot)
  • 3,300mAh battery
    • Bundled with QuickCharge 3.0 charger
  • Android 9.0 Pie with MIUI 10.2.6.0

As mentioned earlier, the Snapdragon 855 wrecks every single phone in our library of phones. The Snapdragon 855 is really, really powerful.

In day-to-day use, it really depends on how well the software is optimized. In the case of MIUI 10, it works very well. It’s snappy and has gesture shortcuts that work instantly.

Gaming

This time around, we have a new test method to test games. We have a way to know the frame rate of whatever application is running on the screen and that is good since many of you are requesting for frame rates.

Firstly, we tried Honkai Impact 3. It came with a new update and now they separated HD assets into an optional download. So here is what I did – downloaded the HD assets and maxed out the graphical settings, then head on to the open world Sakura Samsara with God Kiana and started playing.

I did realize that the frame rate is mostly around 50FPS to 60FPS, with intense battles dipping to ~40FPS. However, God Kiana’s ultimate skill is really graphically intensive, causing the frame rate to dip to ~30FPS.

Then comes Asphalt 9. For unknown reason, the game does not allow highest graphical setting – hence we are stuck at only the default graphical setting. The game is capped at 30FPS and the Mi 9 can run it at 30FPS smooth throughout.

Lastly, PUBG Mobile. To our disappointment, PUBG Mobile is not optimized (yet again) and the highest possible graphic settings is at HDR with ultra frame rates. We also turned on anti-aliasing and disabled adaptive graphic quality.

The Mi 9 can run PUBG Mobile consistently ran at 40FPS, so there is no issues whatsoever.
