In the mobile world, there are devices that set the tone for the industry for several years to come, such as the Xiaomi Mi 8, which has become a real phenomenon in the smartphone market. Users often search for information about when it was born to assess the relevance of its technical characteristics in the current 2026. Understanding the release date helps determine the life cycle of the device and its real value in the secondary market.
This is the first in the brandβs lineup to feature a cut-out display and an advanced face unlock system that works even in the dark, and the year of release is a key one here, as it was during this period that Qualcomm introduced its top-end chipset, which is still capable of handling most everyday tasks, and we will take a closer look at the timeline for the model and its modifications.
Many buyers confuse the date of the announcement with the date of the start of sales in different regions, which leads to misunderstanding when choosing a used device. It is important to clearly distinguish when the phone was shown to the public and when it actually entered the retail network of Russia and CIS countries.
Official release date and presentation
The Xiaomi Mi 8 was unveiled on May 31, 2018, and was held in China to celebrate the companyβs 8th anniversary, which explains the choice of the model name. It was on that day that the manufacturer officially revealed all the maps, showing design, technical specifications and announcing the recommended retail price. May 2018 was the starting point for the entire Mi 8 series.
But the global premiere, which focused on the European and Russian markets, was later held on August 27, 2018, at the IFA exhibition in Berlin, at which the company confirmed that the device is adapted to work with Googleβs international frequencies and services, and the gap between the Chinese and global announcements was almost three months.
β οΈ Note: Do not confuse the date of the presentation with the date of the start of sales. Between the first display and the appearance of the phone in stores usually takes from 2 to 4 weeks, necessary for logistics and certification.
The launch in China began on June 8, 2018, just a week after the announcement, which allowed the company to quickly capture the attention of the audience and collect the first feedback. The global version reached the shelves of stores in Europe and Russia only in September-October 2018. The official release year of the Xiaomi Mi 8 is 2018, regardless of the month of purchase in a particular region.
For collectors and those buying the device now, it's important to know these dates: Early batches released in June 2018 may have differences in display or memory module suppliers compared to devices assembled at the end of 2019.
Technical characteristics and productivity
At the heart of the smartphone was the flagship Qualcomm Snapdragon 845 processor. At the time of release, it was the most powerful chip based on Android, made on a 10-nanometer process. In 2026, it can no longer compete with modern leaders, but still ensures smooth operation of the interface and most applications.
RAM ranged depending on the modification: the basic versions were equipped with 6 GB, and the top-end versions β 8 GB. The type of memory LPDDR4X provided a high speed of data exchange. Built-in storage UFS 2.1 also worked quite quickly, although it was inferior to modern standards UFS 3.1 and 4.0.
- π Processor: 8-core Snapdragon 845 with a frequency of up to 2.8 GHz.
- πΎ Memory: Combinations 6/128 GB 8/256 GB.
- π± Screen: Super AMOLED 6.21-inch diagonal.
- π Battery: 3000mAh with Quick Charge 4 support+.
The Adreno 630 graphics accelerator built into the processor was great in games at the time. However, today's heavy projects may require a minimum of graphics settings. The cooling system in the form of a graphite pad and a copper tube helped cope with heating, but under prolonged loads, the trottling was noticeable.
Secrets of the Snapdragon 845 processor
Itβs worth noting that the NFC module supported all the standards for contactless payment in this model. Mi Pay and Google Pay were stable, which was an important advantage over competitors in this price segment for 2018. In terms of connectivity, the phone received dual-band Wi-Fi and Bluetooth 5.0.
Camera: Breakthrough technologies of 2018
The main focus of the Xiaomi Mi 8 was on photo capabilities, the smartphone became the world's first phone with dual-frequency GPS support, which significantly improved navigation accuracy, but it was the camera that became the main trump card. DxOMark rated the photo module at 105 points, which was an absolute record at the time of release.
The main camera was made up of two modules: Sony's IMX363 main sensor with f/1.8 aperture and optical stabilization was responsible for detailing; the two-zoom and f/2.4 aperture telephoto lens allowed for high-quality portraits and pictures in good light; artificial intelligence was used extensively to recognize scenes and optimize colors.
| Parameter | Main camera. | Telephoto lens | Front camera. |
|---|---|---|---|
| Permission | 12 MP | 12 MP | 20 MP |
| Diaphragm | f/1.8 | f/2.4 | f/2.0 |
| Stabilization | 4-axis OIS | No. | No. |
| Pixel size | 1.4 ΞΌm | 1.0 ΞΌm | 0.9 ΞΌm |
The 20MP front camera used pixel-combination technology to improve sensitivity, which in 2018 allowed selfies to be taken in acceptable quality even in low light conditions, and the beatification algorithms could be turned off or customized to your liking through the settings menu.

To improve the quality of night shooting on Xiaomi Mi 8 use a tripod and turn on manual mode, setting ISO to a minimum, as noise reduction algorithms can "blurn" details.
Video was shot at 4K at 60 frames per second, which was the cutting edge, but it's worth remembering that optical stabilization only worked on the main module, so when shooting with a telephoto lens or front camera, the shaking could be noticeable. Slow-mod allowed video to slow down to 240 frames per second at 720p.
Display and ergonomics of the body
The screen became one of the main topics of discussion when the smartphone was released. Samsung's Super AMOLED matrix provided deep black and saturated shades. Full HD+ resolution (2248Γ1080) at a diagonal of 6.21 inches gave a pixel density of about 403 ppi, which ensured the clarity of the image.
The cutout at the top of the screen, often referred to as a "bang," contained a front-facing camera, sensors and speaker, and it housed an IR transmitter and a face-unlocking backlight system. Unlike its competitors, the Xiaomi Mi 8 could recognize the wearer even in complete darkness thanks to an additional flash.
The body is made of Gorilla Glass 3 glass on the front and back, and the frame is made of aluminum alloy. Despite the glass panels, wireless charging was not in this model, which was a disappointment to many fans of the brand. The dimensions of the device were quite standard for 2018, but in 2026 it may seem narrow due to the more elongated proportions of modern screens.
- π¨ Color gamut: Black, Silver, Blue, Gold.
- π‘οΈ Protection: Oleophobic coating and glass Gorilla Glass 3.
- π Jack: USB Type-C 2.0 with support OTG.
- π§ Audio: No 3.5mm connector, only adapter included.
β οΈ Warning: Gorilla Glass 3, mounted on the Mi 8, resists scratches well, but does not tolerate falls.The use of protective glass and a high-sided case is necessary for the safety of the screen.
The device's ergonomics are rated by users as comfortable: The phone doesn't slide in the hands thanks to matte bezels processing, but the back glass panel is quickly covered with fingerprints, especially in black.The device weighs 175 grams, making it easy for its class.
Software and updates
At the time of launch, the Xiaomi Mi 8 was running Android 8.1 Oreo with a MIUI 9 shell. Subsequently, the smartphone received updates to Android 10, which was the official end of support for major versions of the operating system. However, security updates and patches for the MIUI shell came for a long time.
In 2026, the device will likely run on custom firmware or stay on the latest official version of MIUI 11 or 12 if updates are still available for some regions.System optimization in newer versions of MIUI could negatively affect the performance of the old hardware, so many users preferred to stay on MIUI 10.
βοΈ Checking the condition of the used Xiaomi Mi 8
For advanced users, customized recaps and firmware were always available, and unlocking the bootloader on Mi-series models was always a relatively simple procedure, allowing them to install pure Android or lightweight versions of the shells, extending the life of the device.
The relevance of the purchase in 2026
Buying the Xiaomi Mi 8 in 2026 makes sense only as a budget solution or a second phone. Its performance is still enough for instant messengers, navigation, YouTube and simple games.
The main advantage of buying now is the price. In the secondary market, the cost of the device has dropped to a minimum. AMOLED-The screen and the sound is pretty good, which is rare in the 2026 ultra-budget segment.
On the other hand, battery wear will be critical over 7-8 years of use, and the new owner will likely need to change the battery immediately, and some banking applications may have compatibility issues due to an outdated version of Android and the lack of security certificates.

The Xiaomi Mi 8 in 2026 is a great choice for a first smartphone for a child, or as a device for navigating in a car, but not as a basic phone for an active life.
