Xiaomi Redmi 9C processor: full technical review and tests

Why the processor is important for the Redmi 9C

Xiaomi Redmi 9C is a budget device that offers balanced performance despite the affordable price tag. The heart of any smartphone is a processor, and in this case, it determines not only performance, but also multitasking, energy efficiency and application compatibility. If you are planning to buy or already own a Redmi 9C, it is important to understand what its chipset is capable of.

In this article, we will take a closer look at what processor is installed in the Xiaomi Redmi 9C, study its architecture, compare it with competitors and give practical recommendations for optimizing work. Particular attention will be paid to the questions that most often worry users: whether the chipset supports modern games, how it affects battery life and whether to count on software updates.

What is the processor Xiaomi Redmi 9C: specifications

The Xiaomi Redmi 9C is based on the MediaTek Helio G35 processor, a 12nm chipset designed specifically for budget smartphones, which is part of the Helio G line, which is focused on gaming capabilities, but in this case the emphasis is on the balance between performance and power consumption.

The main parameters of the Helio G35:

• 🔹 Architecture: 8 cores ARM Cortex-A53 clockwise.
• 🔹 Graphics accelerator: PowerVR GE8320 680 MHz.
• 🔹 Process technology: 12 nm (obsolete but optimized for budget solutions).
• 🔹 Memory support: LPDDR4X (Up to 6GB in theory, but in Redmi 9C maximum 3GB).
• 🔹 modem: 4G LTE Cat-7 (Maximum download speed – 300 Mbit / s).

Importantly, the Helio G35 does not support 5G networks, as expected for a 2020 device, but for most tasks — social networks, instant messengers, video watching — it has enough capabilities.

Architecture and performance: what does 8 Cortex-A53 cores mean?

The MediaTek Helio G35 is based on the ARM Cortex-A53 cores, which are mid-range versatile cores that balance performance and energy efficiency. Unlike the flagship Cortex-A76 or Cortex-X1 core chips, there is no big- and small-core division (big.LITTLE technology). All 8 cores operate on the same architecture, but at different clock speeds depending on load.

Advantages of this architecture:

• ✅ Stable multitasking: thanks to 8 cores, the smartphone copes with the simultaneous launch of several lightweight applications.
• ✅ Low energy consumption: Cortex-A53 Optimized for budget devices, which extends battery life.
• ✅ Good software support: most apps and games are adapted to this architecture.

But there are drawbacks, such as in resource-intensive tasks (such as rendering video in 4K or playing games at maximum settings), the Helio G35 is inferior to more modern chips, and it is worth considering that the 12-nanometer process is less energy efficient compared to the 7 nm or 6 nm used in new smartphones.

💡

If you notice that Redmi 9C has started to “brake”, try turning off animations in the developer settings. To do this, go to Settings → About Phone → MIUI Version (click 7 times), then to Settings → Additional → For developers and set the animation scale to 0.5x or turn off completely.

Comparison with competitors: Helio G35 vs Snapdragon 460 vs Helio G25

To better understand the capabilities of the Helio G35, compare it with its closest counterparts in the budget segment: the main competitors are the Qualcomm Snapdragon 460 and MediaTek Helio G25.

The table shows that the Helio G35 is slightly superior to the Helio G25 in CPU and graphics frequency, but inferior to the Snapdragon 460 in process technology.

• 📊 In synthetic tests (e.g., AnTuTu) Helio G35 round-up 100-110 thousand points, that on 10-15% higher than Helio G25, but 5-10% lower than the Snapdragon 460.
• 🎮 The difference is less noticeable in games: both MediaTek chipsets show similar results in the game. PUBG Mobile or Call of Duty Mobile in Medium Settings.
• 🔋 The Snapdragon 460 wins in terms of energy efficiency thanks to a more modern process technology.

💡

The Helio G35 is the best choice for a budget smartphone if you want a balance between performance and price. For high-setting games or resource-intensive tasks, consider devices with a Snapdragon 6xx or Helio G8x.

Gameplay: Will Redmi 9C pull up to modern games?

One of the key questions when choosing a smartphone is its ability to run mobile games. Xiaomi Redmi 9C with a Helio G35 processor is positioned as a device for everyday tasks, but many users want to know whether it is possible to play PUBG Mobile, Genshin Impact or Free Fire.

Test results in popular games:

• 🎮 PUBG Mobile: Average settings (Balanced) with a frame rate of 30 FPS. At high settings, slowdowns are possible.
• 🎮 Call of Duty Mobile: Low/medium settings with frequency 40-50 FPS. In multiplayer modes, drawdowns can be observed to 30 FPS.
• 🎮 Free Fire: High settings with 60 frequency FPS (But with periodic friezes in intense scenes).
• 🎮 Genshin Impact: Minimum settings (10-15 FPS). The game is possible, but it is not comfortable to call it.

To improve the gaming experience, it is recommended:

1. Close the background applications before starting the game.
2. Use performance mode in battery settings (Settings → Battery → Performance mode).
3. Disable automatic update of applications in the background.

Important! body temperature during long gaming sessions can rise to 45-50°C. This is normal for budget smartphones, but it is not recommended to play more than 1-1.5 hours in a row without interruptions.

The effect of the processor on autonomy: how long the battery lasts

The processor directly affects the power consumption of the smartphone. Helio G35 is not the most energy-efficient chipset on the market, but thanks to optimization by Xiaomi and battery capacity of 5000 mAh Redmi 9C shows good results in autonomy.

Approximate working time in different scenarios:

• 📞 Calls: until 30 clockwork 3G/4G.
• 🎥 Video viewing: up to 18 hours (YouTube, Netflix at average screen brightness).
• 🎮 Games: 6-8 hours (depending on the load).
• 🌐 Internet surfing: up to 12 hours (Wi-Fi or mobile data).

Tips for extending autonomy:

⚠️ Note: If you notice that the battery has become discharged much faster (for example, the smartphone does not keep even 5 hours in downtime), this may indicate wear of the battery.

Updates and Support: Should You Expect MIUI 14 or Android 13?

The Helio G35 processor supports Android 10 out of the box, but Xiaomi has released updates to Android 11 (with a MIUI 12.5) for the Redmi 9C. The question of further updates worries many owners.

Xiaomi’s official policy on updates for budget devices:

• 📱 Android: 1 major update (from Android 10 to Android 11).
• 🔄 MIUI: support 2-3 years from the date of issue (up to) MIUI 13 inclusively).
• 🚫 Android 12/13: unlikely to be Redmi 9C Due to iron restrictions and manufacturer policies.

If you’re critically interested in newer versions of Android, consider more modern models like the Redmi 10C or Poco M5. However, for most tasks, MIUI 12.5 on Android 11 provides all the necessary features, including:

• 🔒 Improved data protection.
• 🎨 New widgets and design themes.
• 🔋 Optimization of energy consumption.

⚠️ Note: Install custom firmware (for example, LineageOS) on Redmi 9C It's possible, but it's fraught with a loss of warranty and unstable performance. G35 It has limited support in the developer community, so many features may not work properly.
