The Xiaomi Mi 9T boots the latest MIUI 10 ROM based on Android 9 Pie. While lightweight and intuitive, MIUI is no vanilla Android, so it will take a couple of hours for the purists to get the handle of it.
The Mi 9T supports Always-on display and you can schedule it or leave it on/off all the time. There are various themes you can choose from and make it yours.

You can unlock the screen via the improved under-display fingerprint scanner. The reader is very easy to set up and works surprisingly fast. The accuracy is superb, too, and overall it's great for your daily unlocking.
You can also set up face unlock in addition to it - it's equally fast as the Mi 9T wakes up the moment you pick it up. Note that the face unlock option may not be available in all regions.
Xiaomi Mi 9T has a Dark mode - it will switch all system colors from white to black and this way you can save some battery juice by making the best use of the power-efficient AMOLED screen. Note that not all apps support the dark mode, but the majority do.
The Mi 9T also comes with various live wallpapers including the cool 24-hour wallpaper - it changes depending on the time of day and is quite nice, indeed.
There is no app drawer in MIUI so all your apps are just sitting there on your homescreen, but you can still add them to folders. Of course, you can always install a third-party launcher if you really miss the app drawer.
Here are the default home screens on Mi 9T. There's a weather widget in the upper right corner across from a large clock widget. There is a Quick Card pane, the leftmost one. It contains different cards with relevant information - recent apps, step counter, notes, calendar events, the weather, and favorites, among others. You can configure what shows up here, or you can disable this altogether.

The task switcher felt a bit awkward at first, but we've grown to like it. It shows all of your recent apps in two columns. Tap and hold on a card for the split-screen shortcut, or just swipe it left or right to close it.

Themes are supported on the Xiaomi Mi 9T, but the app appears only when the phone is set to a supported region, say India.
MIUI also offers a Security app. It can scan your phone for malware, manage your blacklist, manage or restrict your data usage, configure battery behavior, and free up some RAM. It can also manage the permissions of your installed apps and allows you to define the battery behavior of selected apps and applies restrictions only to the apps you choose.
MIUI also offers proprietary Gallery, Music, and Video player. In some regions, the music and video app include paid streaming options. FM radio app is available, too.

In some markets, the pre-installed applications by Xiaomi will show ads, which is how Xiaomi's is compensating for the relatively low prices of its devices. We're reviewing a global version of the Mi 9T and we didn't see any ads at all.

The Adreno 618 GPU sounds beyond promising on paper and should be more than adequate to handle all 1080p content. Indeed, it can only be bested by the flagship Adreno 640 inside the S855 SoC, which was kind of an overkill beneath the 1080p's screen of the Mi 9.

Finally, there is no real difference between the Adreno 616 inside the Mi 9 SE's S710 and the Adreno 618 within the Mi 9T.

Some say AnTuTu never lies, and the compound test indeed put the Mi 9T on top of every other competitor. The only one that could beat it is the Mi 9.
The Snapdragon 730 is bridging the gap between the mid-range and the flagship classes, very successfully at that. It has one of the most powerful processors to date, and the GPU will handle whatever game you threw at it for the next couple of years to come.
Sure, the Mi 9 has the Snapdragon 855 with twice as much graphics power, but it mostly goes underutilized as it is not needed on its 1080p display. So, for most, if not all, intents and purposes you won't feel a difference between the Mi 9 and Mi 9T as far as flagship gaming is concerned.
Finally, the Mi 9T's Snapdragon 730 stays cool enough under peak performance and we didn't notice any throttling.
