Xiaomi Mi 5 Plus: what processor is installed and what it is capable of

The question of what processor is in Xiaomi Mi 5 Plus often arises from users planning to buy a device in the secondary market, or enthusiasts seeking custom firmware. This smartphone, released in 2016, became a kind of “dark horse” in the lineup of the company, offering a flagship filling in the case, which was originally not positioned as a premium.

Understanding the architecture of this processor is critical to assessing the relevance of the device today. Xiaomi Mi 5 Plus (also known as Redmi Pro in some regions, although technically different, but similar devices on the hardware) is based on 64-bit platform from Qualcomm. It was this chip that allowed the smartphone to demonstrate impressive results in synthetic tests of the time, bypassing many competitors from the middle and even upper price segment.

However, when choosing a device with this hardware years after release, you need to consider not only dry numbers of hertz. The manufacturing process and architecture of the cores determine not only the speed, but also the heat generation, as well as energy efficiency. In the following sections, we will discuss in detail why this model SoC has become legendary and what restrictions it imposes on the use of a smartphone in today’s environment.

Technical characteristics of the Snapdragon 820

The centerpiece of the Xiaomi Mi 5 Plus is the Qualcomm Snapdragon 820 quad-core processor (model MSM8996), Qualcomm’s first chip to use its own core architecture called Kryo. Unlike previous generations that used standard ARM Cortex cores, Kryo enabled engineers to achieve a better balance between performance and power consumption, and the chipset was made using a 14-nanometer FinFET process, which was considered an advanced solution at the time.

The processor architecture is built on the scheme of big.LITTLE, but with its own interpretation of Qualcomm. It includes two high-performance Kryo cores with clock speeds up to 2.15 GHz and two energy-efficient cores with a frequency of 1.6 GHz. This configuration allowed the system to dynamically switch between power modes depending on running tasks.

It is important to note the support of modern memory standards at the time. the processor is paired with LPDDR4 type of RAM at a frequency of 1866 MHz, which provides high bandwidth. This is especially important for heavy applications and games, where the speed of data exchange between the CPU and RAM plays a crucial role. In the Xiaomi Mi 5 Plus, the amount of RAM varies from 3 to 6 GB, which, combined with a fast memory controller, gives a noticeable increase in performance.

⚠️ Note: Despite the high nominal frequency, the actual performance of Kryo cores may differ from the standard ones. Cortex-A72/A53 specific tasks due to differences in instruction set and compiler optimization.

When buying a used Xiaomi Mi 5 Plus, pay attention to the version of the chip: early revisions of the Snapdragon 820 could have a higher level of defection or unstable modem operation.

Kryo core architecture and performance

The main feature that distinguishes the Xiaomi Mi 5 Plus among contemporaries is the introduction of Kryo cores. It is not just a marketing name, but the result of a deep reworking of the ARMv8 architecture. Qualcomm engineers optimized the processing pipeline, which allowed to achieve a high IPC (number of instructions per clock), in practical use this is expressed in a more responsive interface and faster application launch.

The Snapdragon 820’s single-core performance was revolutionary for its time; Benchmarks have performed better than many of its Exynos and MediaTek rivals. However, multi-core performance is limited to just four physical cores. In today’s environment, with applications increasingly optimizing for 6 and 8 cores, this factor could be a bottleneck for the Xiaomi Mi 5 Plus.

The Adreno 530 graphics processor also deserves special attention.It supports the Vulkan API, OpenGL ES 3.2 and OpenCL 2.0.This means that the smartphone is theoretically able to run modern games, albeit with limited graphics settings. In 3DMark tests, the device scores solid, but real-world gaming practice shows that after a few minutes of load, trottling begins.

• 🚀 Single-core speed: Exceeds many modern budget-friendly customers thanks to Kryo’s high frequency and optimization.
• 🎮 The Adreno 530 still supports most popular games, but not at maximum settings.
• ⚡ Energy efficiency: 14 nm process technology has significantly reduced energy consumption compared to 20 nm predecessors.

The cooling system and the problem of trottling

Despite the advanced 14nm process technology for its time, the Xiaomi Mi 5 Plus Snapdragon 820 faced a well-known problem of overheating. The design of the smartphone did not include an active cooling system or massive graphite gaskets, which became the standard later, as a result, with prolonged load, the processor quickly reaches critical temperatures, which triggers the mechanism of trottling (forced frequency reduction).

In the first minutes of heavy applications or when the system is updated, the processor gives maximum performance. However, once the crystal temperature exceeds the threshold value (usually about 40-45 ° C on the body), the frequency of the Kryo cores is reset to minimal values to prevent damage, this leads to sharp "freezes" of the interface and a drop in FPS in games.

Users often point out that in the summer or when using the navigator, the Xiaomi Mi 5 Plus can get hot in the hands, a direct consequence of the SoC under load. The cooling system in this device is passive and relies on heat sink through the metal frame and back cover, which does not always effectively cope with the heat package of the flagship chip.

⚠️ Warning: Prolonged overheating of the processor can lead to battery degradation and detachment of display plumes.Do not leave the Xiaomi Mi 5 Plus in direct sunlight while running.

Comparison with competitors and analogues

To understand the Xiaomi Mi 5 Plus’s place in history, it is necessary to compare its processor with competitors of the period. The main rival was Samsung’s Exynos 8890, which was installed in the Galaxy S7. The Korean chip had 8 cores (4+4) versus 4 in Qualcomm, but lost in single-core performance. In real tasks, the difference was minimal, but in the multitasking Exynos felt more confident.

Another competitor was MediaTek Helio. X20/X25 with its unique architecture from 10 But despite the larger number of cores, Snapdragon 820 Xiaomi Mi 5 Plus has often been more stable and better optimized by game developers.The Adreno graphics block has traditionally been considered more compatible with emulators and heavyweights. 3D-applications than Mali from ARM, mediatek.

The table below compares the key characteristics of the Xiaomi Mi 5 Plus processor with its closest competitors:

💡

The Xiaomi Mi 5 Plus has the same processor as the OnePlus 3, but due to differences in the cooling system, it can show different results in long tests.

The effect of the processor on autonomy

The energy efficiency of the Snapdragon 820 was a step forward compared to the “hot” Snapdragon 810, but still inferior to later solutions. Xiaomi Mi 5 Plus has a battery capacity of 4000 mAh (depending on the specific modification, since the Mi 5 Plus is often confused with the Redmi Pro, where the battery is 4050 mAh, or the standard Mi 5 with 3000 mAh).

In standby and light load mode (social networks, messengers), the processor efficiently uses energy-efficient cores with low frequency, providing up to 1.5-2 days of operation. However, once powerful Kryo cores are activated, energy consumption increases exponentially, which is due to the fact that it requires much more voltage to achieve high performance.

Users planning to use the Xiaomi Mi 5 Plus as their main smartphone should keep in mind that battery degradation over the years makes things worse. An old battery paired with a gluttonous processor under load can discharge in 3-4 hours of active screen. Optimization of MIUI also plays a role: background processes can wake the processor, preventing it from going into deep sleep.

• 🔋 Standby mode: Excellent efficiency thanks to aggressive background management.
• 📉 Load: Fast discharge when cameras are launched or navigation due to operating at maximum frequencies.
• ⚙️ Optimization: MIUI It has built-in energy saving algorithms that limit the background activity of applications.

Relevance of the processor in 2026-2026

Nearly a decade after its release, the Xiaomi Mi 5 Plus and its Snapdragon 820 processor have moved into the category of retro devices. For basic tasks - calls, WhatsApp, YouTube at 720p/1080p - there is still enough power. The interface can slow down in heavy shells, but in "pure" Android (via custom firmware) the device comes alive.

However, current security and API requirements make it difficult to use this processor, and many of Google’s banking apps and services are no longer supporting architectures older than a certain API level that Kryo has trouble pulling on new versions of Android. Official support for Android has stopped at version 8.0 Oreo, a critical limitation.

For enthusiasts, this smartphone remains an interesting platform for experimentation. With an unlocked bootloader and a community of developers, you can install LineageOS or Pixel Experience. In such conditions, the processor opens up better, because the extra add-ons of MIUI are resourceless. But you shouldn't expect miracles from a 4-core chip in the era of 8-core monsters.

⚠️ Warning: Installing unofficial firmware on old iron may cause the camera or module to fail NFC Due to the lack of drivers in new Linux kernels.
