Choosing a budget smartphone in 2026 has become a challenge that requires careful analysis of characteristics. The market is saturated with models that look identical but hide a completely different philosophy of work under the hood. The user facing the dilemma of whether to buy a Samsung Galaxy A12 or Xiaomi Redmi 9, often lost in an abundance of technical terms. These two devices became real bestsellers of their time, setting new standards in the lower price segment.
Both smartphones offer decent characteristics for their money, but their target audience and approach to resource optimization differ significantly. Samsung traditionally relies on the stability of the One UI software shell, while Xiaomi attracts customers with an aggressive pricing policy and rich functionality of the MIUI shell. In this article, we will conduct a deep analysis so that you can make an informed decision.
Don't rely on the manufacturers' marketing slogans alone, because real performance often depends on the quality of system optimization. The key to choosing between these models is not so much the processor as the screen's energy efficiency and the quality of the shell optimization. Let's take each aspect in detail to see which device will last you longer.
Body design and ergonomics
The look of the smartphone is the first thing the owner encounters. Samsung Galaxy A12 is made in a strict, minimalist style, typical for the Korean company. The back cover has a pleasant texture that prevents fingerprints from appearing, which is a definite plus for everyday use. The dimensions of the device allow you to comfortably control it with one hand, although the weight is quite noticeable.
In turn, the Xiaomi Redmi 9 offers a bolder and more youthful design. The rear panel is often decorated with concentric circles or geometric patterns, which makes the phone visually unique. However, the body materials here are simpler - plastic feels cheaper to touch compared to the competitor. The dimensions of the Redmi 9 are also large, but the mass distribution may seem less balanced.
The ergonomics of the control buttons also play a major role. On Samsung, the volume and power buttons have a clear, short stroke, which is convenient for blind printing. Xiaomi's buttons can seem tighter, especially in new devices. The location of the fingerprint scanner on the side of both smartphones has become standard, but Samsung's read speed and accuracy has traditionally been higher.
- 📱 Samsung A12: Strict design, matte texture, the best build.
- 🎨 Xiaomi Redmi 9: Bright design, glossy elements, plastic body.
- ⚖️ Ergonomics: Samsung is in the hand more confident due to weight.
- 🔘 Buttons: the keys of Samsung is nicer and quieter.
⚠️ Note: When buying Xiaomi Redmi 9, pay attention to the presence of a protective case in the kit, as a slippery case can cause a fall.
Choosing between aesthetics and practicality, many are leaning toward Samsung’s more restrained option, but if you’re looking for a unique look that will make the device stand out from the crowd, Xiaomi offers more color variations.
Display and multimedia quality
The screen is a window into the digital world, and here the difference between the competitors becomes noticeable. Samsung Galaxy A12 is equipped with a PLS IPS matrix with a diagonal of 6.5 inches. Resolution is 720p (HD+), which for such a diagonal gives not the highest pixel density. Color reproduction is set in warm colors, which is familiar to fans of the brand, but the margin of brightness in the direct sun may not be enough.
Xiaomi Redmi 9 also uses an IPS panel, but with a slightly higher resolution of 1080p (FullHD+).This makes the picture much clearer, fonts look smoother, and the pixel grid is not noticeable. Support for Reading Mode 3.0 technology allows you to effectively filter blue light, reducing eye strain during long reading.
Samsung's sound system is represented by a single speaker located in the lower end. The sound is monophonic, loud enough, but devoid of deep bass. Xiaomi also equipped its budget phone with a single speaker, but the sound amplification algorithms in MIUI often make the audio flatter and sharper at high frequencies.
- 📺 Resolved: Xiaomi wins at the expense of FullHD+ against HD+.
- 🎨 Samsung offers more natural colors.
- ☀️ Brightness: Both smartphones suffer under direct sunlight.
- 🔊 Sound: Both have mono-dynamics, average quality.
⚠️ Attention: On the Samsung Galaxy A12 By default, you can have your vision protection mode on, which makes the screen yellow. Check the display settings for correction.
Productivity and gaming opportunities
The heart of the Samsung Galaxy A12 is the MediaTek Helio P35 processor, an eight-core 12nm chip that focuses on energy efficiency rather than performance records. It works consistently for everyday tasks like social media and instant messengers, but there can be micro-latency when switching between heavy applications.
Xiaomi Redmi 9 has a more powerful chipset MediaTek Helio G80, which is positioned as a gaming budget. It is built on 12-nm process technology, but has more productive cores Cortex-A75. In synthetic tests such as AnTuTu, Redmi 9 scores almost twice as much as the competitor, which gives a tangible advantage in heavy applications.
In games, the difference becomes critical. On Samsung, modern projects like PUBG Mobile or Call of Duty Mobile will have to run at minimal graphics settings, and even then FPS drawdowns are possible. Xiaomi allows you to play at medium settings with a more stable frame. Xiaomi's cooling system also copes with heating slightly better, although the body still warms.
Comparison of AnTuTu v9 (example points):
Samsung A12: ~110,000 points
Xiaomi Redmi 9: ~200,000 points- 🚀 Processor: Helio G80 Xiaomi is more powerful than Helio P35.
- 🎮 Games: Xiaomi pulls games on average, Samsung – only on minimal.
- 📉 Heat: Samsung is warming less, but also running slower.
- 💾 Memory: The speed of the eMMC 5.1 drive is the same for both.
Cameras and photo quality
Photographing on budget smartphones is always a compromise. The main module of the Samsung Galaxy A12 has a resolution of 48 MP. During the day, it takes good pictures with good dynamic range. Photo processing algorithms from Samsung try to make the colors richer, which most users like to post on social networks without additional processing.
The main camera Xiaomi Redmi 9 also received a module of 13 MP (interpolation up to 48 MP in some modes). Detailing during the day is acceptable, but the MIUI algorithms often unnecessarily sharpen (increase sharpness) images, creating artifacts. In low light conditions, both smartphones lose detail and begin to “noise”, although the night mode Xiaomi works a little faster.
Special attention should be paid to additional modules: Samsung has an ultra-wide-angle camera at 5 MP and a macro lens at 5 MP. Xiaomi has a similar set: 8 MP width and 2 MP macro. The quality of shooting on auxiliary cameras is low for both competitors - they serve more to tick the specs. Front-facing cameras (8 MP at Samsung and 8 MP at Xiaomi) cope with video calls, but miracles from them should not be expected.
| Characteristics | Samsung Galaxy A12 | Xiaomi Redmi 9 |
|---|---|---|
| Core module | 48 MP, f/2.0 | 13 MP, f/2.2 |
| Wide angle | 5 MP | 8 MP |
| Macro | 5 MP | 2 MP |
| Video | 1080p at 30 fps | 1080p at 30 fps |
⚠️ Warning: Don't use digital zoom on these smartphones, the image quality will drop to pixel porridge.
Autonomy and charging speed
The battery is one of the strengths of both devices. The Samsung Galaxy A12 has a 5,000mAh battery. With a less-performing processor and low-resolution screen, the smartphone is doing great. In mixed-use mode, it lives easily for a day and a half to two. It's the perfect choice for those who forget to charge their phone overnight.
Xiaomi Redmi 9 also got a 5020mAh battery. However, a brighter and sharper screen, as well as a powerful processor, consume more power.However, autonomy remains at a high level - a confident day of active work. Xiaomi's main trump card is support for fast charging with 18 watts, although the package often contains a 22.5 watt block (depending on the region).
☑️ Checking the battery's health
Samsung’s full charging speed leaves much to be desired – around 2.5-3 hours of standard 15W charging. Xiaomi handles about 2 hours.It’s important to note that both smartphones have a USB Type-C connector, which is the de facto standard, but Samsung often doesn’t have a charger bundled with it, which increases the total cost of ownership.
- 🔋 Capacity: Both smartphones have about 5000 mAh.
- ⚡ Charging: Xiaomi charges faster and has a unit bundled.
- ⏳ Samsung lives longer because of the weaker screen and CPU.
- 🔌 Jack: USB Type-C in both models.
Software and updates
The software part is where Samsung traditionally breaks ahead: The One UI Core shell, while stripped down in visuals, works stably and logically. Samsung guarantees to receive security updates for several years, which is critical for data protection. The interface is handy to control with one hand thanks to the shift of controls down.
Xiaomi offers a MIUI shell that is functionally richer but can be overloaded with ads and redundant apps. Redmi 9 has a lot of pre-installed software out of the box that can be removed, but it takes time. The notification system in MIUI works differently than in pure Android, which can be addictive. Updates come less often and support ends faster.
The issue of data security is also worth considering: Samsung has a Knox platform that provides an additional layer of protection, even in the budget segment. Xiaomi has protection standard for Android, but the history of collecting telemetry sometimes raises questions_privacy_ user-oriented.
Final comparison of characteristics
To sum up, both smartphones are great options for different types of users. Samsung Galaxy A12 is the choice of conservatives who care about reliability, long-term support and predictability. Xiaomi Redmi 9 is the lot of enthusiasts and gamers who are willing to put up with the features of MIUI for better performance and better screen.
If you want a phone for a child, an elderly relative, or a second work device, go with Samsung. If the smartphone is the main one, and you like to play or watch high-resolution video, Xiaomi's pick. Both devices are still relevant in 2026 as budget solutions for basic tasks.
