Many users are still searching for information about the Xiaomi Mi 4, which was introduced as the smartphone was a turning point in the history of the brand. It was this model that brought the Chinese manufacturer from the segment of budget devices to the ranks of serious competitors flagships of the time, in 2026, interest in it was caused not so much by the desire to buy a new device, but by the need to restore, reflash or buy a collectible copy.
The release date of the device directly affects the choice of software and understanding of what applications will work on it. Over the years since its release, many versions of the Android operating system have changed, and the hardware of this gadget has its own clear limitations. Understanding the context of the era when the phone was created helps to avoid disappointment when it is used in today’s digital world.
In this article, we will take a closer look at the timeframe, the technical features, and whether it makes sense to interact with this device today, why the design of this smartphone is still considered a reference, and also get instructions for updating the software.
Official release date and model history
The Xiaomi Mi 4 was unveiled on July 22, 2014 in Beijing, a landmark event as the company first bet on premium materials, abandoning the all-plastic body characteristic of previous Mi 2S and Mi 3 series. Launching globally and in India later in early 2015 often creates confusion among buyers seeing different dates on boxes.
The device was marketed as a “flagship killer,” offering the characteristics of top Samsung and Apple models at half the price. In 2014, it was a real breakthrough that allowed the brand to gain a foothold in the minds of consumers as a manufacturer of quality gadgets. Lei Jun, the company’s founder, personally introduced the device, emphasizing the metal frame and production process.
⚠️ Warning: There are many refurbished devices on the market that are being sold as new. If you are offered a new Xiaomi Mi 4 in 2026, it is likely a used device after the body was replaced, since the production of the original units was stopped many years ago.
The historical value of the model is that it set the standards for subsequent generations. It was after the Quad that the company began to experiment more with shapes and materials, which eventually led to the creation of ceramic cases in the Mi Mix series. It is important for collectors and enthusiasts to know the exact year of release to determine the revision of the board or the firmware version.
Technical characteristics in terms of time
At the time of its release, the smartphone had outstanding performance characteristics that today seem basic, but then provided high performance, and the heart of the device was the Qualcomm Snapdragon 801 processor, which has long been one of the most stable and energy-efficient solutions.
However, when comparing the specs to today’s standards in 2026, there is a significant difference: whereas 3 GB of RAM was considered redundant, today’s heavy applications and web pages can cause a shortage of resources. A screen with a diagonal of 5 inches and a resolution of 1920×1080 pixels is perceived as compact today, but its pixel density (441 ppi) still provides a clear picture.
- 📱 Screen: IPS LCD, 5.0 inches, protected by Corning Gorilla Glass 3.
- 🚀 Processor: Quad-core Snapdragon 801 with a frequency of 2.5 GHz.
- 📸 Camera: 13 MP with aperture f/1.8, video-capable 4K (with limitations on stabilization).
- 🔋 Battery: Non-removable, with a capacity of 3080 mAh, which for 2014 was an excellent indicator of autonomy.
Network support is an important aspect: 4G LTE was just gaining momentum in 2014, and while the phone supports it, it lacks many of the frequencies used by carriers in 2026, which can lead to unstable signal or only 3G/2G in some regions.
Relevance of the device in 2026
Using the Xiaomi Mi 4 as a primary smartphone in 2026 is next to impossible due to software limitations: Official operating system support ended with Android 6.0 Marshmallow, and most modern apps require newer API versions.
However, the device has several use cases, which can be turned into a media center, a digital photo frame, or an in-car navigation device that doesn't require constant internet connection and background work, and is popular among developers for testing compatibility of older applications.
The physical wear and tear of the battery is important, because the lithium polymer battery has degraded in almost all of the batteries in 12 years, even if they were on a shelf, and the battery bloating is the main safety hazard when you turn on long-out devices.
💡
Before the first inclusion of the old Xiaomi Mi 4, be sure to check the case for battery bloating. If the back cover has moved away or the body is deformed, it is strictly forbidden to turn on the device!
Software and Update Opportunity
The issue of firmware is especially acute for owners of this model. Official updates through the Settings menu → About the phone → System update has not come for a long time. The latest stable release of MIUI refers to the version of MIUI 9 based on Android 6.0.
To extend the life of a smartphone, enthusiasts use custom firmware such as LineageOS or Pixel Experience. However, installing unofficial software requires unlocking the bootloader, which sometimes causes difficulties with drivers on older devices. The firmware process requires strict adherence to instructions, since an error can lead to a “brick”.
☑️ Preparation for the reflashing of Xiaomi Mi 4
⚠️ Note: When installing custom firmware on Xiaomi Mi 4, there are often problems with the camera drivers and Wi-Fi module. Before installing, be sure to study the Known Bugs section on the developer forum.
If you decide to stay on the stock system, it is recommended to conduct a full reset (Wipe Data) through Recovery Mode to remove the accumulated software debris.
Comparison with modern state employees
To understand how outdated the Mi 4 is, just compare it to current budget models from 2026-2026, such as the Redmi Note series or the base Xiaomi.The performance difference is colossal: modern entry-level chips often overtake the 2014 flagship in benchmarks.
Below is a table showing the gap in characteristics between the legend of 2014 and the conditional modern state budget:
| Characteristics | Xiaomi Mi 4 (2014) | Modern Budgetary Officer (2026) | Difference |
|---|---|---|---|
| RAM | 3GB LP-DDR3 | 6-8 GB LP-DDR4X/5 | 2-3 times more |
| Android version | Android 6.0 (officially) | Android 14/15 | 8-9 years difference |
| Network support | 4G LTE (Cat. 6) | 5G / Wi-Fi 6 | Communications generations |
| Camera. | 13 MP (without OIS) | 50+ MP (with OIS and AI) | Quality and function |
As the comparison shows, buying the Mi 4 for everyday tasks (social media, navigator, YouTube) makes no economic sense. Modern public sector employees are not much more expensive in the secondary market, but offer incomparably better experience.
