The Xiaomi Book S in tablet mode

The Xiaomi Book S is a 2-in-1 laptop with a lot of potential. The sleek design and optional keyboard make it easy to use, but the performance underwhelms during productivity tasks and it doesn’t work well as a standalone tablet, which makes it hard to recommend.

Introduction

The Xiaomi Book S is a 2-in-1 laptop that packs a Qualcomm Snapdragon 8cx Gen 2 processor and a bright and vibrant display, but the performance leaves something to be desired.

One of the most popular 2-in-1 laptops on the market is the Microsoft Surface Pro 8, which has now been taken over by the Surface Pro 9 – and the competition since then has been minimal.

Now Xiaomi has thrown its hat into the ring with the Book S, which has followed in Microsoft’s footsteps by not bundling the supported keyboard in with its device. I’ve been using the Book S for a good few weeks now, here is how I got on.

Design

  • Sleek and mature design
  • Keyboard has to be brought separately
  • Limited number of ports

The Xiaomi Book S can be used as a tablet, but if you also purchase the supported keyboard – which will cost you another £129 – it can also be used as a makeshift laptop. On its own, it weighs in at 720g, with the keyboard coming in at an extra 317g.

For a 2-in-1 device, I thought it was surprisingly heavy and I could really feel it in my backpack when I took it to and from work. I think it felt very similar to carrying a traditional laptop, which was a little disappointing, as I expected it to feel more portable.

The tablet itself has an aluminium-magnesium alloy body, and it has a sleek and mature design, housing a 13MP camera module on the back. However, for ease, I kept the back cover connected to the device for almost all of the times I used it. The back cover and keyboard are made of faux leather and have a similar aesthetic, with the Xiaomi branding written on the back.

I did like the keyboard, despite it being smaller than what I’m used to. It felt similar to the keyboard that supports the Huawei MateBook E, having a good response time and a good key depth. However, on many occasions, it took a while for the words that I typed to actually appear on screen, although we will touch on that more in the Performance section.

The touchpad was also serviceable, but it had a similar feel to the Acer Swift X (2022), which is to say it felt like I had to apply more pressure than usual to highlight text or click on a link, which slightly slowed down my productivity.

Housed on the side of the device are the power and volume buttons, which were tactile and responsive. Xiaomi has opted against using a fingerprint sensor, instead using facial recognition via Windows Hello. This worked great and made logging into the device feel seamless.

It is pretty bare-bones in terms of ports, with only one USB-C connection (which doubles as a charging port), a 3.5mm audio jack and a TF card slot. I struggled with this setup, as it meant I needed a dongle to connect older USB-A peripherals.

However, I was impressed by the audio. For a small device, I felt like the dual speakers could pump out loud audio that sounded consistent and sharp, making watching TV and movies a breeze. Music sounded natural and balanced, with bass notes coming out as particularly favourable.

  • 12.4-inch display
  • Over 500 nits
  • 2560 x 1600 resolution

Easily, the best part of the Xiaomi Book S is the screen. While it’s small at just 12.3-inches, it has a resolution of 2560×1600, ensuring a sharper picture quality than Full HD (1920×1080) displays. Despite packing an LCD panel and not OLED, the colours were vibrant and it handled low-light shows and movies with ease.

To back up my personal thoughts, I also ran some tests with a colorimter, which showed the max brightness to sit at 557.83 nits, with the contrast coming in at 1430:1. The brightness is particularly impressive and much higher than the 300-nit count found on most laptops. This even made it easy for me to work outside on sunny days, and it definitely elevated a lot of media content.

The colour accuracy also came out as reliable, with the sRGB, Adobe RGB and DCI-P3 coming in at 97.9%, 85.2% and 93%, respectively. Colour gamuts are measurements of the range of colours that a device can display, being a key metric for how realistic colours on screen will look in the real world.

Since this is a 2-in-1 device, it has touchscreen capabilities, and I was pleased to find that it was very responsive. I could quickly skim through a document or zoom into pictures with no issues, and I felt like navigating it as a tablet was fairly simple, despite the fact that Windows 11 is not built with that in mind.

The refresh rate of the Book S is stuck at 60Hz and cannot be altered. While this does not surprise me, it would have been nice to see an adaptive refresh rate so it could challenge the likes of Microsoft’s Surface Pro 9.

The Xiaomi Book S boasts two cameras; a 1080p front camera and a 13MP rear camera. Both of these were serviceable, but in terms of actual use cases, I got a lot more out of the front camera, using it for work calls and chatting with friends. It had more detail than I expected, though I thought that both cameras struggled with exposure.

While the rear camera was a nice inclusion, it felt cumbersome to whip out for a quick shot, and I wouldn’t recommend using it if you already own a smartphone with a camera. As you can see from the pictures below, it was good to use outside in bright daylight, and I felt like the colour accuracy on my books and plants were high. But in darker environments, the colours are washed out easily.

  • Underwhelms during basic productivity tasks
  • Slow loading times
  • Struggles to perform as a standalone tablet

The Xiaomi Book S comes in one processor configuration; a Qualcomm Kryo 495 CPU. It also came with 8GB LPDDR4X RAM as well as 256GB storage. While I felt the RAM was fair, I was disappointed to see no more storage options past 256GB, with 512GB generally being the base option for a laptop.

I really struggled to use this device for office work. The small screen size made it hard to work with multiple tabs open, and generally, it felt like
