Mi 11 Ultra In-Depth Review

With the Mi 11 Ultra, Xiaomi must have been trying to make the best phone money can buy right now. At around $1300, this is no doubt an expensive phone, but the price is justifiable.

I’m not sure if it’s the phone’s internal hardware or the physical appearance of the camera module that is more striking.

Inside the box find, a USB Type-C headphone jack adapter, a standard clear case, a 67W fast charger, and a USB-C charging cable.

The Xiaomi Mi 11 Ultra Full Review

At look at the specs, we saw above in a little more detail.


Mi 11 Ultra Review

The Mi 11 Ultra comes in only two-color options; Cosmic White and Cosmic Black.

One thing that is really clear about this phone, is that not everyone will love the way it looks, especially on the back. There’s a gargantuan rear camera bump with three huge lenses and a small 1:1-inch secondary display. The camera module is about a quarter of the phone’s thickness. However, since it does not stretch too much downwards, it is not a nuisance at it is conveniently out of reach of fingers. Since it stretches nearly from end to end, it really solves the wobble process, meaning the phone doesn’t wobble when put on a surface on its back.

Instead of glass, the back is made of ceramic. There are only 2 disadvantages about this; One, it collects fingerprints a lot and the density of ceramic makes the phone much heavier than most other phones (234g).

Just like the Mi 11, the Mi 11 Ultra has a Power button, USB-C port, an IR Blaster, and a Volume locker – all in the same position. Even more, it has IP68 protection, which means it is waterproof and dust-proof up to 1.5meters deep for 30 minutes.

The phone also has stereo speakers which are tuned by Harman/Kardon.


Mi 11 Ultra Review

The Mi 11 Ultra’s screen’s display is phenomenal to say the least. It features an A+ 6.81-inch AMOLED QuadHD+, 140Hz refresh rate, GGV, HDR10+ adaptive panel. The display maxes out at 1700 nits of brightness making the brightest phone display ever. It has a 480Hz sample rate making scanning for touches fast and smooth. Even more, it doesn’t have that slight blue shift as you tilt the phone. It doesn’t stop there, even if this is not a 10-bit panel, Xiaomi uses a technology that simulates having a greater color depth. This means it can display 10-bit colors.

It is also quad-curved; It slopes off at both the right and the left, as well as the top and the bottom. The phone has two AMOLED displays. Basically, Xiaomi took the screen of the Mi Band 6 and placed it at the back of the phone, next to the cameras. It is a 1:1-inch small screen display with a really nice customization suite. However, you can only use it for things like displaying date and time, a photo, a quote etc. It can also be used a view finder when taking a photo using the rear camera.

Performance and Software

The Xiaomi Mi 11 Ultra features a Qualcomm Snapdragon 888 chipset, coupled with a 12GB of fast LPDDR5 RAM, making it able to handle most of the things you throw at it fast and smoothly. We ran the latest AnTuTu benchmarks back-to-back five times and the Mi 11 Ultra got an average of 764,497. However, display starts dimming itself quite fast, and you can’t turn the brightness up when it does. The temperature gets a bit higher than that of other competitors, but it doesn’t seem to interfere with the performance of the phone.

The Mi 11 Ultra uses the MIUI operating system. While some people might not like it, all you need to do is take a few minutes to uninstall all the bloatware to leave it as stock Android. You can also set up your home screen however you want it. The operating system is in my opinion stable, fast, and bug and Ad free. You also get fantastic software support


Mi 11 Ultra Review

The phone features a 5000mAh power battery that supports 67W wired and wireless fast-charging. You can fully charge the phone in 40mins Wirelessly or using the USB-C cable and charging brick. According to my tests, it did roughly six hours of screen on time, with settings maxed out.


Mi 11 Ultra Review

The Mi 11 Ultra has three camera sensors at the back. Each camera has a very specialized task. There’s a 50MP main lens, a 48MP ultra-wide lens, and a 48MP telephoto lens. The telephoto lens hits 120x digital zoom and 5x optical zoom. The enormous sensor on the main lens ensures that there’s incredible separation of foreground and background, bright photos, and cinematic videos. The ultra-wide camera is supremely wide. One the downside, the Macro lens wasn’t too pleasing, at least compared to other flagships such as the Samsung S21. The Macro mode is barely able to focus closer than the main camera mode. You can record 8K video at 24fps, 4K at 30fps, or 1080p up to 60fps.

There’s a 20MP camera on the front for taking selfies and vlogging. However, you can also use the rear cameras to take selfies using the small display at the back as a view finder. The 1:1-inch display can also be used as a view finder when vlogging, but sadly, you can only record 15seconds of video.


The Mi 11 Ultra comes in two storage configurations;

  • 12GB of Fast LPDDR5 RAM and 256GB internal storage
  • 12GB of Fast LPDDR5 RAM and 512GB internal storage


I’d say that Xiaomi achieved most of the things they were looking to achieve with this phone. It is a flagship phone that seems to compete really with its rivals, especially the Samsung S21. There’s a little room for improvement like in the front facing camera. It is a phone worth buying and we can only hope that Xiaomi keeps improving their flagships.
