  • Very fast
  • Good main camera
  • Overall, an awesome performer

If you’re looking for the best phone money can buy but don’t want to spend a fortune, you’ll want to check out Xiaomi 12S Ultra. You might have never heard of it, but that’s because it only launched in Japan last month and doesn’t have an official English version of its website yet. 

Despite that, Xiaomi 12S Ultra is already one of the most successful phones in Japan, and there are more than 10 million people in China who use this phone every day and recommend it to their friends and family.


If you’re in the market for a new phone, you’ve probably never heard of the Xiaomi 12S Ultra. That’s because it’s not available in the United States. But if you can get your hands on one, it’s worth it. 

Here’s why. The Xiaomi 12S Ultra is unbelievably cheap. It only costs $819 and includes features like an 32MP front camera, 6.7 1440x3200px display, and 8GB RAM. Compare that to phones like the Samsung Galaxy S22+, which costs about $1000! 

This is partly due to how successful Xiaomi has been in China–it was recently ranked as China’s second most valuable smartphone maker behind Huawei. 

And with over 100 million Xiaomi smartphones sold worldwide every year, it makes sense that they want to keep prices low so more people can buy their products!

But I will admit it does come with some trade-offs. For example, there’s no NFC for mobile payments and it has a lower resolution display than most flagship smartphones. But if you can get past those minor downsides, it’s still an incredible value! 

Check out my review below to see why! If you’re looking for a great deal on your next smartphone, look no further than Xiaomi.

The Price

At $819, the Xiaomi 12S Ultra is not a cheap phone. But it’s also not as expensive as some of the other flagship phones on the market. For what you get, the price is actually quite reasonable. 

Plus, if you’re looking for a phone with all the bells and whistles, the 12S Ultra has them. That’s not to say it lacks in other areas. On top of featuring some cutting-edge technology, it also offers excellent battery life. 

If you watch a lot of movies or play games on your phone, that feature alone is a major selling point. It also has a high-resolution screen and great performance to boot. In all, there’s very little to dislike about it and plenty to like.

A comprehensive look at what makes Xiaomi 12S Ultra stand out from competitors in its price range as well as its key features.

Design & Build Quality

At first glance, the new Xiaomi 12S Ultra looks a lot like any other high-end smartphone on the market. It has a sleek metal body with curved edges and a large, bezel-less display. 

But upon closer inspection, it’s clear that Xiaomi has put a lot of thought into the design and build quality of this phone. The 12S Ultra is one of the best-built phones I’ve ever used, with an impeccable fit and finish.

Xiaomi has put a lot of thought into the design and build quality of this phone. It looks like a much more expensive device than it is, and it feels incredibly well-built. 

Every single part fits together perfectly, there are no gaps or seams where different parts meet, and all edges are smoothly rounded. It even comes with an IP68 water-resistance rating which means you can use it without worry when rain or spilled drinks get involved.

Xiaomi has also included a few clever design features to make it stand out from other high-end smartphones. For example, there’s no front camera notch or hole on display. 

Instead, Xiaomi built a tiny pop-up camera that automatically rises when you open your camera app. When you’re done snapping pictures, simply close your camera app and it’ll disappear again.


This phone is said to be one of the best phones that you have ever heard of. The phone sports a 6.73-inch display with a resolution of 1440x3200px pixels and an aspect ratio of 20:9. 

Underneath its metal frame, you’ll find a 6.3-inch LCD with 1080 x 2340 pixels and a 19.5:9 aspect ratio. I thought it was a great display overall.

It’s bright, sharp, and accurate to my eyes. It isn’t quite as vibrant as some other displays, but the colors were good overall while viewing angles were decent. 

In a lot of ways, it reminds me of Samsung’s AMOLED displays—except without any notch issues whatsoever (more on that later).

The display is something that you will be excited about if you are looking for a good smartphone at an affordable price. The Xiaomi 12S Ultra is available in three colors, Black, Blue, and Red and it’s also waterproof. 

There is also a second back panel for your phone with a different color called transparent black. If you want to change your phone’s appearance all you have to do is switch out your back panel.

When you are using your phone, you will notice that it is bright. The Xiaomi 12S Ultra features a dual-LED flash with up to 1/2 second exposure which can be used in low light conditions. 

However, it doesn’t have a screen protector which may be a downside for some people especially if they like to use their phones with bare hands and do not always have a case or cover on them. 

One of its best features is that you can make notes directly on your screen by handwriting. This can come in handy when you want to take down important information fast without having to type everything down.

Software & Performance

The Xiaomi 12S Ultra is a budget phone that doesn’t skimp on features. It has a large, bright display, fast performance, and good battery life. Plus, it runs Android 12 out of the box and has a capable camera. 

If you’re looking for a great phone that won’t break the bank, the Xiaomi 12S Ultra is worth considering. The Xiaomi 12S Ultra has a plastic body with a metal frame. It’s not the most premium phone out there, but it feels solid in the hand.

The Xiaomi 12S Ultra has an opening mechanism that I don’t think I’ve seen on any other phone before. There’s a small button on top of its opening mechanism that, when pressed, pops up a portion of its bottom half. 

Pressing it again then pushes up on that section and allows you to slide off the phone’s back plate. Once you do so, you’ll have access to all of Xiaomi’s included accessories and documentation. 

It may take some getting used to before it becomes natural, but I think it works better than having multiple buttons for various actions. Android 12 runs smoothly on Xiaomi’s 12S Ultra. 

There’s no bloatware to be found and apps open quickly. I did notice that some pre-installed apps took a while to load, but that was an anomaly. 

For example, it took a few seconds for Xiaomi’s music app to load when I first opened it and then around 20 seconds before music controls appeared in its interface. Overall, I didn’t have any major issues with software performance.

Camera Quality

The Xiaomi 12S Ultra is a great phone if you’re looking for something with a good camera. It’s a 50-megapixel sensor with 1.4-micron pixels and an f/1.9 aperture. 

There’s also a secondary 48-megapixel Ultra-Wide camera with an f/2.2 aperture for depth sensing. The front-facing camera is a 32-megapixel sensor with an f/2.4 aperture.

Despite being such a great camera, it doesn’t beat out some of its competition. Compared to other high-end phone cameras, like Apple’s iPhone 13 Pro or Samsung’s Galaxy S22 Plus, it falls behind on focus time and also video recording quality. 

Overall though, if you’re looking for a good phone with an incredible camera then you should look no further than Xiaomi’s latest and greatest.

Overall, it’s hard to say a bad thing about the Xiaomi 12S Ultra. It has a great camera, nice design, and incredible battery life. While it doesn’t fall into any categories where it is among some of its best competition, it’s not competing in those areas so you can expect a good phone without all of those bells and whistles. 

If you’re looking for an affordable high-end phone that performs like one then I would highly recommend looking into getting yourself a Xiaomi 12S Ultra.

Special Features Of The Phone

The Xiaomi 12S Ultra is a great phone that has a lot of features that make it stand out from the competition. It has a large 6.67-inch display, a powerful Snapdragon 8 + Gen1 processor, and a triple rear camera setup. Plus, it has a massive 4,860mAh battery that can easily last you all day.

One of our favorite features of Xiaomi’s phone is its display. At 6.73-inches, it’s quite large and will look great on your desk or in your pocket. 

With a resolution of 1440x3200px, it has a crisp pixel density of 522 pixels per inch (PPI). This means everything looks sharp, which is ideal for browsing websites and watching video content like Netflix or YouTube. 

Plus, with an aspect ratio of20:9, you get to enjoy some pretty tall screen real estate without making things awkward while holding it in landscape mode.

Another great feature of Xiaomi’s phone is its battery. It has a 4,860mAh lithium-ion polymer battery that can last for multiple days if you aren’t playing games or streaming videos on it. 

We were able to go for nearly two days without needing to recharge our unit because it can hold so much power. Plus, when you do need to charge it, you only need about an hour and a half!

Battery Life

One of the most impressive things about the Xiaomi 12S Ultra is its battery life. Even with heavy use, I was able to get a full day’s worth of use out of it. 

And when I wasn’t using it heavily, I could easily get two days’ worth of use out of it. Plus, it charges relatively quickly too. In my opinion, the battery life is one of the best features of this phone.

In my testing, I was able to get over a day’s worth of use out of it with moderate to heavy use. It even managed to last around 10 hours while streaming an HD video on loop over a Bluetooth speaker at maximum volume. 

As for charging time, Xiaomi says you can get a full charge in just 1 hour with its included charger. In my experience, that was true. 

From around 10% battery life to fully charged takes just nearly 1 hour, which is impressive compared to many other phones I’ve used that take anywhere from 3-5 hours to charge fully.


One of the best features of the Xiaomi 12S Ultra is its heat resistance. I’ve never had a phone that could withstand the heat as this one can. It’s amazing! Plus, the battery life is incredible. I can’t say enough good things about this phone.

If you often travel or want a durable phone for work, then I highly recommend Xiaomi’s 12S Ultra. It has it all and is one of my favorite phones ever. 

The design is sleek, so it fits easily in any pocket or handbag. And as far as touch screens go, this one feels perfect – no lag time whatsoever when moving from app to app. 

To conclude, Xiaomi 12S Ultra has everything anyone could need in a smartphone – plus bonus perks like durability and heat resistance. So if you’re looking for a reliable new device with exceptional battery life, look no further than Xiaomi 12S Ultra.
