Xiaomi Redmi 9: What is different from other models in the series?

Xiaomi Redmi 9 series has become one of the most popular line of budget smartphones of 2020 — and for good reason. Under this name hides as many as 5 different models: the basic Redmi 9, Redmi 9A, Redmi 9C, Redmi 9 Prime and Redmi Note 9. At first glance, they look the same, but in fact they differ in hardware, cameras and even software. If you are in front of a choice and do not know which version will suit you, this article will help you understand all the nuances.

We've analyzed technical specifications, user reviews, and test results to identify key differences between the models, and there's no generic phrases like "it's a budget smartphone" -- just the specifics of the processors, screens, batteries, and features of each version, and at the end, you'll find a comparison table and answers to the frequent questions that will help you make your final choice.

Let me warn you right away: if you're looking for flagship specs, the Redmi 9 series isn't for you. But if you want a reliable workhorse for a reasonable price, read on. We'll explain why the Redmi 9 Pro is more expensive than the base version than the Redmi 9A is inferior to the Redmi 9C, and why the Redmi Note 9 is often confused with the main lineup, although it's a completely different segment.

1. Xiaomi Redmi 9 base model: what's under the hood?

This version has become the benchmark of the series — all other models somehow start from its characteristics. Redmi 9 is equipped with a processor MediaTek Helio G80, which at the time of release (June 2020) was considered one of the best in the budget segment. This chipset is built on a 12-nm process technology and has 8 cores (2×Cortex-A75 + 6×Cortex-A55) with a clock speed of up to 2.0 GHz.

Graphics accelerator Mali-G52 MC2 allows you to run modern games on medium settings — for example, PUBG Mobile or Call of Duty: Mobile go to 30-40 FPS at HD+ resolution. Of course, to the flagship 90 FPS here is far, but for a budgetary it is more than worthy.

The screen of the Redmi 9 is a 6.53-inch IPS with a resolution of 2340×1080 (Full HD+) and an aspect ratio of 19.5:9. Brightness reaches 400 nits, and protection is provided by Gorilla Glass 3. For comparison: the cheaper Redmi 9A/9C resolution is lower - 1600×720 (HD+).

The 5020 mAh battery supports fast charging of 18 watts, but the 10 watt power supply comes with it, which is an important nuance! If you want to charge your smartphone faster, you'll have to buy an adapter separately.

2.Redmi 9A and Redmi 9C: the most budget pair

The two models are often confused, but they have critical differences: the Redmi 9A is a simplified version without a fingerprint scanner, with one main 13 MP camera and a Helio G25 processor. The Redmi 9C is slightly more powerful: here is the Helio G35, added a fingerprint scanner on the back and a triple camera (13 MP + 2 MP macro + 2 MP depth).

Both models have HD+ (720p) and 5,000mAh batteries, but the 9C supports fast 10W charging (versus 5W for 9A). If you want a minimalist phone for calls and social media, the 9A is perfect. If you want a little better performance and photos, take the 9C.

The main disadvantage of both models is the lack of NFC (you can not pay contactlessly) and a weak processor for games. For example, the Genshin Impact on the Redmi 9A runs only on minimal settings with frequent friezes.

⚠️ Attention: At Redmi 9A There's no proximity sensor! This means the screen won't turn off during the call if you put the phone to your ear. Many users complain of random tapping in this case.

Another important point: Redmi 9C was released in two versions - standard and NFC-version (designated as Redmi 9C NFC), the latter supports contactless payments, but costs 500-1000 rubles more.

3. Redmi 9 Prime: Improved version or marketing?

This model is exclusive to the Indian market, but it is often imported into Russia through parallel imports. In fact, the Redmi 9 Prime is the same Redmi 9, but with an improved main camera 13 MP (versus 8 MP in the basic version) and an additional 8 MP ultra-wide-angle module.

There is also an infrared port (not found in the base Redmi 9) that allows you to control appliances through the Mi Remote app. The processor, screen and battery remain the same - Helio G80, Full HD+ IPS and 5020 mAh.

If you want a smartphone with the best photo capabilities in the series, but without overpaying for the Redmi Note 9, the 9 Prime is a good compromise. However, note that the warranty on “gray” devices may not work in official Xiaomi service centers.

4.Redmi Note 9: Why isn't it quite Redmi 9?

Many people mistakenly think that the Redmi Note 9 is just a “pumped” version of the Redmi 9. In fact, this is a separate line that belongs to the segment of “premium budget”: here is a completely different processor – MediaTek Helio G85 (instead of the G80), the more powerful graphics accelerator Mali-G52 MC2 and 4 GB of RAM (versus 3-4 GB in Redmi 9).

The screen is still the same – 6.53′ Full HD+ IPS, but the cameras are much better.

- Main: 48 MP (vs. 13 MP in Redmi 9 Prime)

- Super wide-angle: 8 MP

- Macro: 2 MP

- Depth sensor: 2 MP

The battery here is 5020 mAh with support for fast charging of 18 watts (there is an adapter included), and the Redmi Note 9 received NFC, infrared port and stereo speakers (the Redmi 9 only has one speaker).

The key difference is that the Redmi Note 9 has a metal body (against the plastic one of the Redmi 9), which makes it more premium to the touch. However, the weight of the device has increased to 199 g (versus 198 g of the Redmi 9).

⚠️ Note: Redmi Note 9 uses a hybrid slot for SIM-The card is either two nano-SIMs or one nano-SIM. + In Redmi 9, the slot is separate, which is more convenient for those who use two SIMs and a memory card at the same time.

Comparative table: all Redmi 9 models in one place

As you can see from the table, the Redmi Note 9 compares favorably with other models in terms of camera, processor and NFC, but also costs 30-50% more than the basic version. If you do not need 48-MP photos and contactless payments, overpaying for the Note 9 does not make sense.

6. Which Redmi 9 model to choose in 2026?

It all depends on your priorities. Here's a quick checklist for you to choose.

We need the cheapest phone for calls and messengers → Redmi 9A

I want a slightly better camera and fingerprint scanner, but the budget is limited. → Redmi 9C

7. Frequent problems and how to avoid them

Charge to 80-90%, not 100%.

Calibrate the battery once every 3 months (full discharge + charging without interruptions).
