Xiaomi Redmi 9A is one of the most popular budget devices of 2020, and it is not surprising that users are interested in its technical capabilities. CPU is the heart of any gadget, which depends on speed, multitasking and even battery life. In this article, we will analyze in detail which processor is installed in the Redmi 9A, study its architecture, compare with competitors and give practical recommendations for optimizing performance.
The Redmi 9A is marketed as an affordable smartphone for basic tasks like social media, instant messengers, video watching and light gaming. But even in the low-end segment, manufacturers are trying to offer balanced solutions. The MediaTek Helio G25 processor that underpins this device is a prime example of this approach. But how effective is it in practice? Let's get a sense of it.
Technical characteristics of the MediaTek Helio G25 processor
The MediaTek Helio G25 processor is built on a 12nm process and belongs to a family of chips focused on budget and entry-level gaming smartphones. Its architecture includes 8 cores divided into two clusters:
- 🔹 4 cores Cortex-A53 clock speed up to 2.0 GHz – responsible for productive tasks;
- 🔹 4 cores Cortex-A53 frequency up to 1.5 GHz – save battery power in simple operations.
The PowerVR GE8320 graphics accelerator runs at up to 650 MHz and supports modern APIs such as OpenGL ES 3.2 and Vulkan 1.1. This allows you to run most mobile games at low to medium settings. However, you should not expect high FPS in demanding projects like Genshin Impact or Call of Duty: Mobile.
One of the key advantages of Helio G25 — support LPDDR4X-RAM (in Redmi) 9A fixed 2 or 3 GB depending on modification) and eMMC 5.1-This allows faster downloading of applications compared to older standards, and the chip supports dual cameras up to the end of the day. 13 MPP + 8 MP and video recording in resolution 1080p@30fps.
Architecture and technology: what is hiding the Helio G25
The MediaTek Helio G25 processor is built on the ARMv8-A architecture, which guarantees support for 64-bit applications and modern operating systems. Despite its budget focus, the chip is equipped with several interesting technologies:
- 🔧 HyperEngine Game Technology – Optimizes performance in games through dynamic resource allocation;
- 📶 Dual 4G VoLTE allows you to use two SIM-Cards with voice calls support LTE;
- 🔋 CorePilot – manages heating and power consumption, extending battery life.
MiraVision technology, which improves the quality of the content displayed, automatically adjusts color balance, contrast and sharpness depending on the type of content (video, games, photos), is especially useful on the Redmi 9A screen with a resolution of 720×1600 (HD+), where every pixel counts.
But things aren’t so rosy, for example, the Helio G25 doesn’t support 5G (which is expected for a budget chip in 2020) and is limited to a maximum RAM frequency of 1600 MHz, which means that in multitasking mode, the smartphone can slow down if more than 5-6 applications are open at the same time.
💡
If your Redmi 9A is starting to get a lot of heat in games, try turning on the performance mode in the battery settings. path: Settings → Battery → Performance mode.
Performance in benchmarks: real-world tests
To objectively assess the capabilities of the MediaTek Helio G25, we look at the results of popular benchmarks: In the AnTuTu 9 test, the chip scores about 100-110 thousand points, which corresponds to the level of the Snapdragon 439 or Helio G35. For comparison, the flagship processors of 2023 overcome the mark of 1 million points.
| benchmark | MediaTek Helio G25 | Snapdragon 439 | Helio G35 |
|---|---|---|---|
| AnTuTu 9 | ~105 000 | ~95 000 | ~115 000 |
| Geekbench 5 (Single-Core) | ~160 | ~150 | ~170 |
| Geekbench 5 (Multi-Core) | ~900 | ~850 | ~950 |
| 3DMark Wild Life | ~500 | ~450 | ~550 |
In Geekbench 5, the Helio G25 is showing modest results, with about 160 in a single-core test and 900 in a multi-core test, which is enough for everyday tasks, but you shouldn’t expect record speeds, such as opening heavy web pages in Chrome or working with Photoshop Express can be accompanied by short-term delays.
The situation in games is as follows:
- 🎮 PUBG Mobile - Medium settings, 30 FPS (possible drawdowns of up to 20 FPS battle-fighting);
- 🎮 Free Fire – High Settings, 40–50 FPS;
- 🎮 Clash Royale – maximum settings, 60 FPS.
💡
The Helio G25 will handle most everyday tasks, but for modern games you will have to reduce the graphics settings to a minimum.
Comparison with competitors: who is better?
In the low-end segment, the MediaTek Helio G25 competes with several popular chips.
- 🔄 vs Snapdragon 439: Helio G25 A little faster in games thanks to HyperEngine optimizations, but loses in energy efficiency;
- 🔄 vs Helio G35: younger brother G35 higher-frequency GPU (680 MHz vs. 650 MHz), but the difference in real-world tasks is minimal;
- 🔄 vs Unisoc T610: Unisoc chip loses in performance, but wins in support of 90 Hz displays.
An important nuance: The Redmi 9A with the Helio G25 doesn’t support fast charging above 10W, whereas some competitors (like the Realme C11 with the Helio G35) offer 18W.
Compared to the older Xiaomi models:
- 📱 Redmi 8A (Snapdragon 439 – almost identical performance, but better optimized for the performance of the Snapdragon MIUI;
- 📱 Redmi 9C (Helio G35) — 10-15% faster in games, but the difference is not critical for everyday tasks.

Optimizing performance: how to speed up the Redmi 9A
Even with the modest performance of the Helio G25, the Redmi 9A can be improved by software, and here are some proven ways:
- 🧹 Cleaning Cache and Background Processes: Go to Settings → Annexes → App management; Select heavy apps (e.g. Facebook, Instagram) and click Clear cache; Turn off autoloading unnecessary programs in Settings → Battery → Auto-start.
Initiation of the performance mode
- Activate it in Settings → Battery → Performance mode;
- Note: This will increase battery consumption.
We also recommend:
- 🔄 Update MIUI Up to the latest version (current firmware optimized for Helio) G25);
- 📱 Use easy alternatives to popular apps (e.g. Facebook Lite instead of the main client);
- 🔋 Disable interface animation in Settings → The phone. → Version. MIUI (press 7 times) → Additional settings → Windows animation (select) 0.5x).
☑️ Redmi optimization 9A play-off
Warning: Do not install custom firmware (like LineageOS) on the Redmi 9A without experience.Unofficial builds are often not optimized for the Helio G25 and can lead to overheating or rapid battery discharge.
Frequent Processor Problems and Solutions
Redmi 9A users sometimes face typical Helio G25 issues, and consider the most common and ways to fix them:
⚠️ Warning: If the smartphone starts to warm up for no apparent reason (even in a simple one), this may indicate a malfunction of the thermal paste or a bloated battery.
- 🔥 Overheating in games: Solution: lower the graphical settings in the game, use a game booster (such as Xiaomi's Game Turbo) and play in a ventilated room.If the temperature is above 50°C, take a 10-15-minute break.
- 🐢 Lags for multitasking: Solution: Limit the number of background applications to 3-4. In the developer settings (Settings) → The phone. → Version. MIUI (7 taps) → Developer Mode: Set a Process Limit of 2-3.
- 🔋 Fast battery drain: Solution: Turn off constant account sync and application background activity. Check battery consumption in Settings → Battery → Using a battery and removing "gluttonous" programs.
If problems persist after all the manipulations, it may be worth considering hardware diagnostics, for example, battery wear or damage to the motherboard can simulate the "brake" of the processor.
Should I buy the Redmi 9A in 2026?
When it was released in 2020, the Redmi 9A was a great choice for its money, but with the development of technology in 2026, its position weakened.
Pros:
- ✅ Low price (from 6000-8000) ₽ secondary-market);
- ✅ Sufficient performance for social media and calls;
- ✅ Long battery life (5,000 mAh battery).
Cons:
- ❌ Outdated firmware (last updated) MIUI released in 2022);
- ❌ A weak processor for modern games and multitasking;
- ❌ Absence NFC and fast-charging.
If you need a smartphone for basic tasks and your budget is tight, the Redmi 9A may still be an option, but for gaming, photography or long-term use, it’s better to consider newer models like the Redmi 12C (Helio G85) or the Poco C50 (Helio A22).
💡
In 2026, the Redmi 9A is only suitable for secondary tasks (calls, instant messengers, video) and for everything else, it is better to choose a newer model.
