Xiaomi Mi 9: Everything you need to know

The Xiaomi Mi 9 is the powerhouse smartphone 2019 has been waiting for

Xiaomi has announced the Mi 9 for release in Europe and China, after several weeks sharing key pieces of information about the device to fuel our excitement. It doesn’t disappoint, as it not only brings the Snapdragon 855 processor with it, but also Xiaomi’s first triple-lens camera, and a beautifully designed glass body too. Here’s everything you need to know about it.

The Xiaomi Mi 9 is made from glass, with a sheet of 2.5D Gorilla Glass 6 on the back, and Gorilla Glass 5 on the front over a 6.4-inch AMOLED screen with a 2340 x 1080 pixel resolution. The body comes in four different colors. The standard black looks great, but the lavender and blue versions are really stunning. Additionally, there is a transparent version, just like we saw with the Mi 8 Pro Explorer Edition. Again, you’re not seeing actual components, just representations, but there’s no denying it’s an eye-catching look.

Performance and battery

There’s some serious firepower inside the Mi 9, as it holds the very latest Qualcomm processor — the Snapdragon 855 which can run at speeds up to 2.84GHz. The Mi 9 has 6GB of RAM and comes with either 64GB or 128GB of internal storage space. Xiaomi is one of the first manufacturers to announce the inclusion of the new chip, along with OnePlus and Lenovo.

The 3,300mAh battery may sound quite small, but the Snapdragon 855’s increased efficiency should see it last for longer than expected. Additionally, the Mi 9 comes with wireless charging, and Xiaomi has engineered its own wireless, 20-watt fast charger. It’s an extra — set to cost around $25 — and will charge the phone in about an hour and 40 minutes. Use the cable, and a full charge will come up in an hour and five minutes, according to Xiaomi.


This is the first time Xiaomi has used a triple-lens camera on one of its smartphones, and it has gone all-out with the specification. The main lens is Sony’s IMX586 sensor, just like that fitted to the Honor View 20, and it has 48 megapixels with an f/1.75 aperture, plus some clever pixel binning technology to combine four pixels into one. This enhances image quality in low light.

It’s joined by a 12-megapixel telephoto lens and a 16-megapixel wide-angle lens with a 117-degree field of view. The selfie camera has 20-megapixels, and each camera is enhanced by artificial intelligence. This includes A.I. portrait modes, a night mode, and scene detection. Xiaomi co-founder Wang Chuan via the Weibo social network recently published some images taken with the Mi 9, to show off its ability.

Security, software, and special features

A fifth-generation fingerprint sensor is set under the screen. It’s a step beyond the sensor fitted to the Mi 8 Pro, and promises to deliver greater speed and more reliability. It has a special feature, too — hold it down and three shortcuts appear when the phone is unlocked: A search button, a calendar reminder, and a QR code scanner.

On the side of the phone is an extra button used to call up Google Assistant, although it can also be programmed to perform other tasks, including opening the camera app. The Xiaomi Mi 9 has Android 9.0 Pie with MIUI 10.2 over the top.

Price and availability

The Xiaomi Mi 9 has been announced for Europe and China, with the global announcement coming at Mobile World Congress in February. The price in Europe has been set at 500 euros, or about $570, but Xiaomi has not confirmed the U.K. price yet. It is due for release soon.

Popular 5G myths you need to stop believing
Worker looking up at 5G tower against a cloudy sky.

As more and more people depend on technology to get things done, the curiosity around the latest tech trends, particularly 5G, is growing. However, 5G is still not as widespread as predicted, leaving people with more expectations than experiences. 
Combine this with the abundance of online information, and you get lots of harmful advice and misinformation about 5G posted by unverified sources. We asked 5G experts to break down four myths and uncover the truth behind how 5G works. Here's what we learned.

Myth No. 1: The rollout of 5G is taking forever
The first 5G devices and networks entered the market over two years ago, yet many populations don’t have access to 5G today. Is the 5G rollout that slow?
Truth: “Marketing around 5G and 5G phones created hype early and raised expectations that communications providers are still catching up to, but when you look at the technology deployment timelines, 5G is actually rolling out faster than 4G,” says Shawn Carpenter, program director, 5G & Space, for Ansys. “The U.S. has lagged many of the progressive Asian and European markets in delivering new C-band services that will enable the long-expected increased bandwidths, but 2022 will see marked progress in tower service deployments.” 
You also need to consider the pandemic when analyzing the 5G timeline. The worldwide lockdowns and travel restrictions significantly affected supply chains and slowed the adoption of 5G.
Yet, despite these hindrances, more than 41 million people were subscribed to 5G mobile phone service last year, and the number is growing rapidly. “If you have a phone capable of C-band 5G service, you should see elevated service in most U.S. cities during 2022,” Carpenter said, adding that “a few 5G handset users in select downtown city locations may be able to access the new mmWave ultrawide bandwidth service at 28 GHz.”

Is 5G dangerous? We asked an expert

As 5G rolls out across the nation, we're all looking forward to faster download speeds and reliable high-speed connectivity. One of 5G's biggest breakthroughs is harnessing millimeter wave (mmWave) spectrum for faster data speeds. But there are concerns this very high-frequency spectrum could pose adverse health effects for the public, including some very pervasive 5G conspiracy theories.

These kinds of concerns aren’t new -- consumer anxiety concerning whether radiofrequency radiation can increase the risk of cancerous tumors existed long before cell phone towers were even a thing. To get some concrete answers on the subject, we reached out to the U.S. Food and Drug Association (FDA), a government agency that is responsible for protecting public health through the control and supervision of not only food and medicine but also electromagnetic radiation emitting devices. We further supplemented those responses with information sourced from the American Cancer Society and the International Agency for Research on Cancer. So is 5G dangerous? Keep reading to find out.
