The question of which processor is installed in the budget smartphone Xiaomi Redmi 9A, often becomes decisive when buying an entry-level device. This gadget, which appeared on the market as an affordable solution for basic tasks, is equipped with a chipset MediaTek Helio G25, which is positioned as a game, albeit with serious reservations. Understanding the architecture and real capabilities of this processor is critical, because it depends on whether you can comfortably use instant messengers or the device will slow down even when typing.
Many users mistakenly believe that the Xiaomi brand guarantees high optimization even on weak hardware, but in the case of the Redmi 9A, the processor is the main bottleneck of the entire system, it is made on an outdated process and does not support modern energy efficiency standards, which directly affects battery life and body heating. In this article, we will analyze the technical specifications, compare them with competitors and find out what the chip is really capable of in 2026.
It is worth noting that MediaTek Helio G25 Does not support networking 4G LTE two-way SIM-It's a big technical limitation for users who are actively using two lines, and it's not a software bug, but a physical feature of the modem architecture embedded in the CPU chip. 4G, This smartphone, alas, will not be able to ensure stable operation of both SIM cards in high-speed mode.
Technical characteristics of MediaTek Helio G25
At the heart of the smartphone is the MediaTek Helio G25, an eight-core chipset introduced by MediaTek back in mid-2020, built on eight Cortex-A53 cores running at a maximum clock speed of up to 2.0GHz. Despite having eight cores, their efficiency is far inferior to modern solutions, as these are old energy-efficient cores, devoid of powerful production units.
Graphics processing takes over the built-in PowerVR accelerator GE8320. This one GPU It's also low-performance, and it's a starter segment that can draw the interface of the system and run simpler ones. 2D-games, but when you try to run a heavy three-dimensional graphics load on it increases critically, causing a drop in the number of frames per second to unacceptable values.
An important parameter is the 12 nanometer manufacturing process. In comparison, today's low-end processors have long since switched to 7 nanometers or even 6 nanometers. A larger process means that transistors are less densely spaced, leading to higher power consumption and higher heat generation at the same processing power, which is why the Redmi 9A can feel appreciable heat even when watching high-resolution video.
Why 8 cores are not always better than 4?
Real performance in benchmarks
To objectively assess the power reserve of the Xiaomi Redmi 9A processor, you need to look at the results of synthetic tests. In the popular benchmark AnTuTu v9, the device scores an average of about 100,000 – 110,000 points. This result is on the lower limit of relevance: modern instant messengers and social networks already require more resources for smooth animations and fast downloading content.
In Geekbench 5, the situation is even less optimistic: Single-core scores around 140-150, which is a very low score, meaning that for tasks that cannot be parallelized into multiple cores (like opening a heavy website or launching an application), the phone will run slowly. Multi-core scores around 800-850, which only confirms the limitations of all eight cores.
Note that test results can vary depending on the firmware version and background processes. However, even the maximum figures do not allow you to call the Redmi 9A a productive device. RAM type LPDDR4X, paired with the processor, also does not differ high speed, creating an additional bottleneck for the system.
Features: PUBG, Free Fire and Genshin Impact
Marketers often refer to the Helio G series as “game,” but in the case of the G25, it’s more of a marketing ploy than a reflection of reality. Let’s take a look at how the processor behaves in popular mobile games. In PUBG Mobile, a smartphone can only run a game at minimal graphics settings. Even though the average frame rate is around 25-30 FPS, and after 15-20 minutes of play, trotttling (resetting due to heat) begins, and the game turns into a slideshow.
Lighter Free Fire or Call of Duty Mobile (low settings) are more stable. 40-50 But the lack of support for modern texture compression technologies and low memory bandwidth prevents the potential of even these optimized games from being realized.
Projects like Genshin Impact or Honkai: Star Rail are best left out by Redmi 9A owners: The processor is physically unable to process the required graphics, and the amount of RAM (often 2 or 3 GB in the basic versions) leads to constant departures of the game to the desktop immediately after booting.
💡
To improve performance in games on Redmi 9A, close all background apps before launch and turn on No Sound or Do Not Disturb mode so the system doesn’t waste resources on notifications.
Heat generation and energy efficiency
One of the main problems with the Helio G25 processor is its inefficiency. As mentioned earlier, the 12-nanometer process is obsolete. With active loads such as navigation, video or video calls, the body temperature in the area of the camera can reach 40-42 degrees Celsius, which is not only unpleasant tactile, but also harmful to the longevity of the battery.
The cooling system in Redmi 9A is a simple graphite gasket that doesn't always handle the heat from the chipset. When the processor heats up, the trottling mechanism is activated. The core frequency is forced to drop, sometimes to 1.0 GHz or lower, causing the interface to twitch and applications to open for 5-7 seconds.
⚠️ Warning: Prolonged use of a smartphone under critical heat (such as navigating in a car in the sun) can cause the battery to bloat or detach from the display due to the expansion of the adhesive layer.
When you're on standby and light load (reading books, listening to music), the processor behaves decently, consuming little power. However, once you run a resource-intensive application, battery consumption increases dramatically. This creates a paradox: with a large battery capacity (5,000 mAh), screen time can be surprisingly low due to the gluttony of the chipset under load.
Comparison with competitors and alternatives
To understand the Redmi 9A’s market position, compare it to competitors in the same price segment. The main rival is often devices based on the Snapdragon 460 or newer Helio G35/G80. The difference in performance between the G25 and G80 is huge: the G80 is almost twice as powerful and is made on a thinner process.
Below is a comparative table of the characteristics of processors, often found in the budget segment:
| Characteristics | Helio G25 (Redmi 9A) | Helio G80 (Redmi 9C/Note 9) | Snapdragon 460 |
|---|---|---|---|
| Technique | 12 nm | 12 nm | 11nm |
| CPU of the core | 8x Cortex-A53 | 2x A75 + 6x A53 | 4x A73 + 4x A53 |
| GPU | PowerVR GE8320 | Mali-G52 MC2 | Adreno 610 |
| AnTuTu v9 (scores) | ~105 000 | ~200 000 | ~180 000 |
You can see that even within the Xiaomi lineup, there are far more productive options, and the overpayment for a Helio G80 model is fully justified by the two-fold increase in power and the presence of powerful Cortex-A75 cores that are responsible for responsiveness. Buying a G25 device in 2026 makes sense only on a very limited budget.
💡
The Helio G25 processor is obsolete: even basic tasks like flipping through Instagram feed can be performed with micro-latency that is not found on G80 and higher chips.
Optimization of MIUI and impact on work
The MIUI shell (or HyperOS in newer versions) is known for its heavyness and resource-intensiveness. On a Helio G25-level processor, the system is often built on compromises. Visual effects, such as blurring the background in the menu or smooth transitions between windows, can work in jerks. It's not a defect of a particular instance, but a consequence of a lack of processing power.
Users often notice that when the system is updated, the phone starts to run slower, because newer versions of Android and shells require more resources for background services, security and advertising. The Redmi 9A processor has a hard time coping with background file indexing and Google services, which leads to the fact that the phone can “hang” even in simple.
There is a method of simplifying the system to speed up the work:
- 📉 Turn off animations in the menu "For developers" (animation scales on the 0.5x).
- 🛑 Turn off advertising in system applications through settings MIUI.
- 🧹 Use lightweight versions of apps (Lite), such as Facebook Lite or Google Go.
- 🔒 Limit background activity for rarely used programs.
⚠️ Warning: Don't install the Play Market accelerators and cleaners on this processor. They consume resources themselves. CPU, Constantly checking the system, which only slows down the Redmi. 9A.
The final verdict: is it worth buying?
To sum up, the MediaTek Helio G25 processor in Xiaomi Redmi 9A is a last-generation solution that is a stretch of the modern mobile Internet, and it is suitable for a narrow category of users: elderly people who need a phone for calls and WhatsApp, or as a second working phone for receiving calls and SMS.
If you plan to use your smartphone to navigate, watch YouTube at 1080p, surf social media, or even more so gaming, this processor will be a source of constant irritation. Slow map opening, long page loading and video calling heat are the realities of using the Redmi 9A in 2026.
When choosing a smartphone, you should look towards models with Helio series processors G80/G85 or Snapdragon 680. The price difference may be minimal, but the difference in user experience will be huge. The savings on the processor in the budget segment is always a compromise with the life of the device comfortable.
