Redmi 9 or Redmi 9C: Comparison of two budget Xiaomi smartphones – what to choose in 2026?

Why the choice between Redmi 9 and 9C is still relevant

Even a few years after its launch, the Xiaomi Redmi 9 and Redmi 9C remain some of the most popular budget smartphones in the aftermarket, and their price-to-opportunity ratio continues to attract customers who are looking for a reliable device for everyday tasks without overpaying for the brand.

At first glance, the difference between the devices seems minimal: both run on MediaTek processors, have similar screens and batteries. However, detailed analysis reveals key differences that can be decisive. In this article, we will compare the models on 10 critical parameters, including performance, camera, autonomy and even nuanced software that Xiaomi does not advertise.

If you're faced with a choice between these smartphones -- whether it's buying a new device in the leftovers or a second-hand version -- this article will help avoid the typical mistakes. We're not going to limit ourselves to dry specs, but to show how these parameters manifest in real use, from the speed of opening apps to the quality of night photos.

1.CPU and performance: Helio G35 vs Helio G80

The main "iron" difference between models lies in chipsets. 9 Powered by MediaTek Helio G80 (12 nm, whereas Redmi 9C He received a more modest Helio. G35 (also 12 On paper, the difference in kernels is small: both have each other. 8 nuclei (2x Cortex-A75 + 6x Cortex-A55 bal G80 vs 4x Cortex-A53 + 4x Cortex-A53 bal G35), But in practice, it does affect:

• 🎮 Games: G80 cope PUBG Mobile on medium settings (30) FPS), then G35 Reduces the schedule to a minimum (20) FPS jerky).
• 📱 Multitasking: On Redmi 9 keep open 5-6 easy applications (messaging, browser), on 9C already 3-4 start.
• 🔄 Updates: Helio G80 Supports more recent versions MIUI (before MIUI 14 based on Android 12, while G35 often "stuck" on MIUI 13.

In synthetic tests, the gap is 40-50% in favor of Redmi 9. For example, in AnTuTu 9, the Helio G80 scores ~ 200,000, and the Helio G35 scores only ~ 120 000. However, for basic tasks (calls, social networks, YouTube), both chipsets have enough power. The critical difference is manifested only when you are busy: editing video, heavy games or working with 10+ tabs in the browser at the same time.

⚠️ Note: If you plan to use a smartphone for Google Camera (GCam) with full processing HDR+, Helio G80 It will do better – it has OpenCL support that is missing from the G35. This directly affects the quality of photos in third-party cameras.

2.Screen: difference in size, resolution and quality

Both models are equipped with IPS-matrixes with a cutout for the front camera (drop-shaped notch), but there are nuances:

In practice, the difference in resolution is noticeable to the naked eye: the text on Redmi 9 looks clearer and the interface is more detailed. This is especially noticeable when watching videos: on 9C, the picture seems soapy due to low PPI. Another important point is the Widevine certification. Redmi 9 supports L1, which allows you to watch content in Full HD on streaming platforms (Netflix, Disney+), whereas 9C is limited to 480p due to Widevine L3.

Both screens have oleophobic coatings, but the Redmi 9 has a more resistant coating – finger marks are less frequent, and the classic model also has better automatic brightness control: it adapts more smoothly to lighting, whereas the 9C often has sharp jumps in backlight.

💡

If you watch video on your smartphone often, look for DC Dimming, a technology that reduces screen flickering at low brightness. Redmi 9 has it (includes in Settings → Screen → Reading Mode), and 9C is missing, which can cause eye fatigue in the dark.

Camera: quantity ≠ quality

On paper, the Redmi 9C looks more attractive due to the triple camera (13 MP + 2 MP macro + 2 MP depth), while the Redmi 9 has only two modules (13 MP + 8 MP ultra-wide).

• 📸 Main camera: Both smartphones use the same Samsung sensor S5K3L6 (13 MPP, f/2.2), but in Redmi 9 It is supplemented by phase autofocus (PDAF), absent 9C. This means that the focus on 9 It happens faster and more accurately, especially in dynamic scenes.
• 🌄 Wide angle: 8MP module in Redmi 9 (118)°) gives noticeably more detailed pictures at the edges of the frame than the software "stretch" in the 9C, which just cuts off the main photo.
• 🌙 Night shooting: Redmi 9 implements hardware Night Mode 2.0 with exposure up to 6 seconds, while in the 9C night mode only lasts up to 3 seconds and often overlights the footage.

Video shooting is also different: Redmi 9 records video at 1080p@60fps, and 9C is limited to 1080p@30fps. Stabilization in both cases is software, but in the classic model it runs smoother thanks to a more powerful processor.

Redmi 9: 1080p@60fps, bitrate ~12 Mbps, EIS (Electronic Stabilization)


Redmi 9C: 1080p@30fps, bitrate ~8 Mbps, no stabilization

⚠️ Attention: At Redmi 9C It's often overheated when you're shooting video for longer periods of time (more than 10 minutes), because you don't have the graphite heat diffuser that Redmi 9 has. If you're planning to shoot videos for TikTok or YouTube, the classic model is more reliable.

4. Battery and autonomy: not everything is so clear

Both models have 5,000 mAh batteries, but the operating time is different from one charge, and the reason is the optimization and hardware features:

• ⚡ Fast charging: Redmi 9 supports 18W (complete 10W), 9C limited 10W. In practice, this means that the classic model is charged up to 100%. ~2 hours 18W-adapter, and 9C — post ~2.5 hours even with the original ZU.
• 🔋 Energy efficiency: Helio G80 (redmi 9) It is built on a more perfect architecture, which gives +15-20% It's autonomous, it's the same load, for example, in a video playback test. 50% redmi 9 worked 18 hours 9C — 14.
• 📉 Discharge on standby: At Redmi 9C There's a higher background flow rate because of a less optimized chipset (8 he loses hours ~3-4%, while Redmi 9 — everything ~1-2%.

An important nuance: Redmi 9 implements Ultra Battery Saver, which when activated turns off the background activity of applications and limits performance, extending the run time to 3-4 days in minimum use mode. 9C this option is not — instead it is only standard saving mode.

💡

If you want a quick charge, buy it separately. 18W-Redmi 9 adapter – it will reduce charging time by 30% compared to the standard 10W-block.

Memory and storage: eMMC 5.1 vs UFS 2.1

One of the most underrated options when choosing a budget smartphone is the type of drive. Redmi 9 uses UFS 2.1, and Redmi 9C uses the outdated eMMC 5.1.

• 📁 Read/Write Speeds: Redmi 9 (UFS 2.1): ~400 MB/s (reading), ~150MB/s (recording) Redmi 9C (eMMC 5.1): ~250 MB/s (reading), ~100 MB/s (recording)
• 🎮 Download games: Genshin Impact on Redmi 9 Texture packets are loaded onto 30-40% faster than 9C.
• 📷 Photos saved: Series from 10 snapshot RAW persist UFS-accumulator 2-3 And then on eMMC, until 5-6 seconds.

Also worth considering is the amount of RAM: Redmi 9 is available in 3/4/6 GB variants, and 9C is only 2/3 GB. In practice, this means that even in the 3GB version, Redmi 9C will reboot background applications more often due to less efficient memory management in the Helio G35.

If you plan to use a smartphone for longer than 2-3 years, UFS 2.1 in Redmi 9 will be a noticeable advantage: eMMC drives degrade faster over time, especially when you often write small files (messaging cache, logs of system applications).

6. Software and updates

Both models were originally shipped with MIUI 12 based on Android 10, but further support varied:

• 🤖 Redmi 9 gets upgraded to new MIUI 14 (Android 12) and stayed on this version.The last security patch came out in March 2026.
• 🤖 Redmi 9C stopped MIUI 13 (Android 11) and security patches stopped coming out after June 2023.

This means that Redmi 9C is vulnerable to new exploits (such as Dirty Pipe or MediaTek SU vulnerabilities), while Redmi 9 will be protected for a while, and features that are not available in 9C are also available in the classic model:

• 🔒 Face unlocking 3D (into 9C only 2D, less reliable).
• 🎵 Dynamic sound (adaptive equalization under headphones).
• 📱 Second Space mode (separation of work and personal profile).

Another important point is unlocking the bootloader: on Redmi 9, this can be done officially through Xiaomi’s website (with a wait of 72 hours), whereas for 9C, the procedure is often blocked due to outdated firmware, which is critical if you plan to install custom firmware (for example, LineageOS or Pixel Experience).

7. Design and ergonomics: plastic vs plastic, but not the same

Both smartphones are made of plastic, but there are nuances:

• 🖼️ Back: Redmi 9 uses matte plastic with a glass texture that gets less dirty. 9C glossy surface collecting prints.
• 🔊 Location of the speaker: In Redmi 9 it is brought to the lower edge, while in 9C — on the back panel (easily overlapped with a finger in landscape orientation).
• 📶 Antenna lines: B 9C They are more noticeable and located closer to the edges, which worsens the reception of the signal when holding the smartphone in your hand.

The dimensions of the devices are almost identical (163.3×77×9.1 mm for 9 vs 164.9×77.1×9 mm for 9C), but the Redmi 9 is 5 grams lighter (198 g vs 196 g). Also in the classic model, a linear-drive vibration motor is implemented (as in flagships), while in the 9C there is a conventional rotary motor that vibrates less clearly.

If you use your smartphone with one hand often, pay attention to the location of the buttons: in Redmi 9, the power and volume buttons are closer to the center, which is more convenient for users with small palms.

8.Price and relevance in 2026

At the time of writing (2026), the prices for models are as follows:

• 💰 Redmi 9 (b/y): from 6 000 to 9 000 rubles (depending on the state and memory capacity).
• 💰 Redmi 9C (b/y): from 4 500 to 7 000 rubles.
• 💰 Redmi 9 (new): rare, but can cost up to 12,000 rubles in leftovers.

Should I overpay for Redmi 9? Definitely yes if:

• You need productivity (playing, multitasking).
• You take photos/video (especially in poor lighting).
• Plan to use your smartphone for more than 2 years (UFS-drive and better optimization).

The Redmi 9C is only worth buying in two ways:

1. The budget is strictly limited to 5,000 rubles.
2. Smartphone is needed for minimal tasks (calls, WhatsApp, rare YouTube).

An alternative to both devices in 2026 can be the Redmi 10C (Helio G88, 90 Hz screen) or POCO M5 (Helio G99), which offer the best price-opportunity ratio, but already in the price range of 10,000-15,000 rubles.

💡

If you choose between the Redmi 9 and the new Redmi 9C at a similar price, take the Redmi 9 – its “iron” is more relevant even after years.
