Xiaomi Redmi Note 5: What processor is installed and what is it capable of in 2026?

Why is the processor in Redmi Note 5 still relevant?

Xiaomi Redmi Note 5 (also known as Redmi Note 5 Pro in some regions) was released in February 2018, but still remains in demand in the secondary market. One of the key reasons is its processor, which even after 6 years demonstrates amazing survivability. In an era when flagship chips become obsolete in 2-3 years, the Snapdragon 636 continues to cope with everyday tasks, and in some scenarios even surpasses budget innovations from 2023-2026.

This article will not only answer the question “Xiaomi Note 5 which processor”, but also reveal the unique features of the architecture of the Snapdragon 636, which make it one of the most balanced chips in the history of Xiaomi. We will analyze the technical characteristics, compare with modern analogues, check the performance in games and multimedia, and give practical tips for optimizing the operation of the smartphone. If you plan to buy a used Redmi Note 5 or already own it, this information will help make an informed decision.

Specifications of the Snapdragon 636 processor in Redmi Note 5

The heart of the Xiaomi Redmi Note 5 is the 8-core Qualcomm Snapdragon 636 (codenamed SDM636), built on a 14-nanometer process. It is the first chip in the Snapdragon 600 lineup to receive the Kryo 260 cores, a modified version of the ARM Cortex-A73 and Cortex-A53 architecture.

• 🔹 4 high-performance Kryo 260 Gold cores (modified) Cortex-A73) clockwise
• 🔹 4 energy efficient Kryo 260 Silver cores (modified) Cortex-A53) frequency up to 1.6 GHz

Important feature SD636 Supports 64-bit computing and LPDDR4X-Memory (up to 8GB), which was a rarity for mid-budget smartphones in 2018.The Adreno 509 Graphics Accelerator delivers performance at the level of the standard. ~100 GFLOPS, This allows you to run most games on the mid-range settings even in 2026. For comparison, the current budget Snapdragon 4 Gen 1 (2023) has performance. ~150 GFLOPS, but loses SD636 energy efficiency.

💡

If the characteristics of the smartphone specified Snapdragon 625 processor – before you model Redmi Note 5 for the Chinese market (code whyred). the International version (vince) is equipped with SD636 and has better performance.

Comparison with competitors: why was the Snapdragon 636 revolutionary?

In 2018, the Snapdragon 636 was a real breakthrough for the segment of smartphones up to 20,000 rubles. P60 MediaTek and Huawei's Kirin 659 were both inferior in performance and energy efficiency. SD636:

• ⚡ 40% faster in single-core tests compared to the Snapdragon 625 (predecessor)
• 🎮 Adreno 509 superior Mali-G72 MP3 (Helio P60) play-play 15-20%
• 🔋 14nm process technology provided a better balance between performance and battery life
• 📷 Support for dual cameras with a resolution of up to 24 MP (competitors limited to 16 MP)

Fun fact: Xiaomi specifically optimized MIUI firmware for the SD636, allowing the smartphone to show results at the level of devices with the Snapdragon 660 in some benchmarks. For example, in the AnTuTu v7 test (2018), Redmi Note 5 scored ~ 115,000 points, while the Nokia 7 Plus with the same chip — only ~ 105 000.

Game and media performance: What’s really pulling the Snapdragon 636 into 2026?

The main question owners Redmi Note 5 — “What games will go on this processor?”. Despite the age, Adreno 509 copes with most projects at medium settings at 720p resolution. Here are the current data on popular games (tested on MIUI 12.5 with 4 GB of RAM):

• 🎮 PUBG Mobile: 30-40 FPS on the "Balanced" settings (graphics "HD", shadows "Low")
• 🎮 Call of Duty: Mobile: 40-50 FPS on the "Mediternary" settings (without anti-aliasing)
• 🎮 Genshin Impact: 20-25 FPS on "Low" (minimum shadows, switched off effects)
• 🎮 Free Fire: 60 FPS on "High" settings (stable)

To improve performance in games, it is recommended:

Important Multimedia Note: Snapdragon 636 Supports Hardware Video Decoding H.265 (HEVC) and VP9, allowance 4K-YouTube and Netflix content without lags, but for 10-bit HDR (For example, Amazon Prime Video requires manual codec configuration through Developer Options.

Energy efficiency and heating: Snapdragon 636 weak spots

Despite its advantages, the Snapdragon 636 has two critical flaws that manifest themselves over time:

⚠️ Warning: For long periods of time (e.g., an hour of play) PUBG Mobile processor temperature can reach 70-75°C, which leads to trottling (automatic frequency reduction), which protects the chip from overheating, but reduces the temperature. FPS on 30-40%. Solution – use a cooling cover or periodic pauses each 20-30 minute.

The second problem is battery degradation, and the high power consumption of the Kryo 260 cores reduces the battery capacity of the Redmi Note 5 (4000 mAh) by 20-30% over 3-4 years of active use, resulting in:

• ⚡ Reduced Autonomous Operation Time with 1.5-2 days 8-12 hours
• 🔋 Increased charging time with 2 hourly 3-4 hours (due to wear of the power controller)
• 📉 Spontaneous shutdowns at charge level below 15%

To diagnose the state of the battery, use the command in ADB:

adb shell dumpsys battery

Look for a health option – if it displays a value of 3 (COLD) or 4 (OVERHEAT), it is a signal to replace the battery.

💡

Replacement of the battery with Redmi Note 5 cost 1500-2500 ruble (2026 year) and return to 80% Use only original batteries marked with the original battery. BM47 or BM48.

Optimization and Overclocking: How to Get the Most Out of the Snapdragon 636

Even in 2026, the Snapdragon 636 can be accelerated with software and hardware modifications.

1. Custom core firmware (e.g., FrancoKernel or ElementalX) allows you to overclock the Kryo 260 Gold core to 2.0 GHz (performance gains of ~10-15%).
2. Disabling unnecessary MIUI services via ADB: adb shell pm uninstall --user 0 com.miui.analytics adb shell pm uninstall --user 0 com.xiaomi.midrop This frees up to 300-500MB of RAM.
3. Using lightweight firmware based on Android 10/11 (for example, Pixel Experience or LineageOS 18.1) They lack the “heavy” MIUI interface and give an increase of 20-25% in benchmarks.

⚠️ Caution: Overclocking the processor reduces the service life of the chip 15-20% It is recommended to use it only with active cooling (for example, a cooler for smartphones), and overclocking will cancel the warranty (if it is still valid).

To check the stability after overclocking, use the test:

adb shell "echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor"

If the smartphone does not restart within 30 minutes of heavy use, the settings can be considered safe.

Next PostNext When to Change the Redmi Note 5?

Despite the survivability of the Snapdragon 636, in some scenarios, the Redmi Note 5 is starting to slow down.

• 🐢 Slowing down animations in MIUI (For example, delays in opening "Recent Applications")
• 📱 Impossibility to upgrade to Android 11+ (The latest official version for Redmi Note 5 is Android 9)
• 🎮 Fall FPS Games below 20 fps even at minimal settings
• 📸 Artifacts in the photo when shooting in HDR or Portrait mode

If you encounter these issues, consider the following replacement options (in order of price/performance ratio):

If the budget is tight, the best choice is the Redmi Note 8 Pro – it retains a 3.5mm connector (like the Note 5) and has similar ergonomics, but with liquid cooling and 90Hz support.
