Xiaomi Redmi Note 4: what year of release and the relevance of the model

Many users are still interested in Xiaomi Redmi Note 4, which year of release, because this smartphone has become a real legend of the budget segment. The model was released in early 2017, but its popularity has not faded for many years thanks to a successful combination of characteristics and price. It was during this period that the Chinese giant Xiaomi finally entrenched itself as the market leader, offering flagship technology in an affordable housing.

It's important to understand that there's a lot of confusion between the two versions of the device, which are released months apart. The global version, known as the Redmi Note 4X, and the Chinese original have different processors, which has a significant impact on their performance. If you're planning to buy a used device or restore an old friend, you need to be clear about these nuances.

In this article, we will take a look at the model’s timeline, the platform’s technical differences, and what to look for when choosing: The Chinese version of the Redmi Note 4 (MTK) was released in January 2017, and the global version of the Redmi Note 4X (Snapdragon) in February 2017, which will help you avoid buying a less productive device.

Chronology of release and variations of versions

The official launch of the smartphone took place in Beijing on January 19, 2017, which is considered the birthday of the model, but the international market was launched a little later, at the MWC 2017 in Barcelona, where the Redmi Note 4X was shown.

The Chinese version was based on the MediaTek Helio X20 chipset, which was considered powerful at the time but had problems with energy efficiency and heating. The global version received the Snapdragon 625, which was a real hit due to the balance between performance and low power consumption, and it was Snap that made this phone a bestseller.

Visually, it was hard to tell the boxes apart, but the labeling on the back will always tell you the truth, and owners should know that the software for these versions also varies, and the firmware is not always compatible with each other without special manipulation.

Technical specifications and platform

The heart of the device that took the world by storm was the octa-core Snapdragon 625, a 14nm processor that achieved great autonomy, which was a crucial factor for many, and a screen with a diagonal of 5.5 inches and a resolution of 1920Γ—1080 pixels provided a clear and vivid picture.

The amount of RAM varied from 3 to 4 GB, and the built-in - from 32 to 64 GB. To expand the storage, a microSD slot is provided that supports cards up to 128 GB. The 13 MP camera with phase autofocus shot quite decently for its time, especially in good lighting.

  • πŸ“± Processor: 8 cores Cortex-A53 2.0 GHz
  • πŸ”‹ Battery: 4100 mAh with fast charging support
  • πŸ“‘ Connection: LTE Cat.6, dual-band Wi-Fi, Bluetooth 4.2
  • πŸ›‘ Body: All-metal with antenna inserts

It is worth noting the presence of an infrared port, which turns the smartphone into a universal remote control of household appliances. MIUI Remote allows you to control TVs, air conditioners and other equipment of various brands, which is rare for the budget segment even in later years.

When buying a used Redmi Note 4, be sure to check the status of the microUSB charging connector, as it often wears out first due to active use.

Comparison of Redmi Note 4 and Note 4X

Many users are wondering if it makes sense to overpay for the X version. The answer is unequivocal: yes, there is a sense, and it lies in the processor. Snapdragon 625 is much less warmed under load than the Helio X20, which ensures stable performance in games and heavy applications.

And the development community support for the Qualcomm version is much broader, and you can find more custom firmware, cores, and modifications for that particular chipset, extending the life of the device for several years after the official end of support.

The table below provides a detailed comparison of the key parameters of both modifications so you can make a balanced choice.

Relevance of the model in the current year

Years after its release, the Xiaomi Redmi Note 4 is still available in the secondary market, but it’s worth noting that today’s apps are becoming more demanding, and basic tasks like calling, messaging, and watching videos are still a challenge.

For games in 2026-2026, this smartphone is already weak. Heavy projects like PUBG Mobile or Genshin Impact will work at minimal graphics settings, and possibly with slowdowns. This device is now a great choice for a first smartphone for a child, for the elderly or as a spare phone.

If you think of it as the main machine, be prepared to compromise. The lack of support for new Android versions from the manufacturer means that data security may be lower than on current models.
