Choosing a smartphone in the mid-range segment always raises a lot of questions, especially when it comes to the legendary Redmi Note series.Two devices, the Xiaomi Redmi Note 8 Pro and Xiaomi Redmi Note 9 Pro, have become real bestsellers, but they offer completely different approaches to performance and functionality.Users are often lost in numbers, not realizing whether to overpay for a newer model or the old flagship is still relevant.
In this article, we will conduct a deep technical comparison to help you make an informed decision. We will look not only at dry specs, but also at real-world experience, features of Android updates and the nuances of the iron platform. Understanding the differences between these gadgets will allow you to avoid wasting money and buy exactly the device that will perfectly fit into your use case.
It's worth noting that the market for used technology is now oversaturated with both, making the price issue a pressing one, but low cost doesn't always mean better buying, given battery wear and software support. Let's see which of these models deserves your attention right now.
Body design and ergonomics
The look of the smartphone is the first thing a user encounters.The Redmi Note 8 Pro has a glass back of the Gorilla Glass 5, which was rare for its price range at the time of its release.It gives the device a premium look, but makes it quite slippery and vulnerable to falls.At the same time, the Redmi Note 9 Pro has switched to plastic, which many took as a step backwards, but the quality of the execution remained high.
The device sizes also vary significantly. The 8 Pro has a 6.53 inch diagonal and a more compact bezels, making it easy to control. The 9 Pro has a larger 6.67 inch screen and a more massive body, which is directly related to the increased battery capacity. The weight of the smartphone has also increased, and prolonged use with one hand can cause fatigue.
⚠️ Warning: Glass back of Redmi Note 8 Pro requires mandatory use of the case, as when falling the risk of breaking the back panel is much higher than that of a plastic counterpart.
The layout of the controls has also changed, with the newer model integrating the fingerprint scanner directly into the side-face button, a solution that was much more convenient and faster than the rear sensor in the Redmi Note 8 Pro, which often required the device to be removed from the table to unlock.
Screen and image quality
Both smartphones are equipped IPS-full resolution matrices HD+, But the technology is different. The Redmi Note 8 Pro uses a classic version. IPS LCD It's a panel that provides good viewing angles, but the black is more of a dark gray color. 450 nits of brightness is enough for indoor use, but in the direct sun, readability drops.
The Redmi Note 9 Pro has an improved display with Gorilla Glass 5 and higher peak brightness. Although the technology remained IPS, color calibration and contrast were improved by Xiaomi engineers. It also has splash protection, which does not formally make the phone waterproof, but saves from occasional raindrops.
- 📱 Screen diagonal Note 8 Pro is the 6.53 resolution 2340×1080 pixel.
- 📱 The Note 9 Pro’s screen is larger at 6.67 inches, giving it a wider multimedia space.
- 📱 The pixel density in both models is approximately the same and is about 395 ppi.
The important aspect is refresh rate. Neither model has received 90 or 120 Hz while remaining on the standard 60 Hz. However, thanks to the optimization of the MIUI shell, the animations on both devices look smooth. For gamers, the lack of high hertz may be noticeable in dynamic shooters, but for everyday surfing this is uncritical.
Productivity and gaming opportunities
The heart of the Redmi Note 8 Pro was the MediaTek Helio G90T. At the time of release, it was a real power monster that beat many competitors in benchmarks. The chipset is made on a 12-nm process and has two powerful Cortex-A76 cores. However, this medal has the flip side - high heat generation.
Redmi Note 9 Pro is based on Qualcomm Snapdragon 720G. This processor is made on a thinner 8-nm process. In synthetic tests, it may be inferior to a competitor from MediaTek, but in real life, behaves more stable. The cooling system here works more efficiently, and the phone less often resets frequencies during prolonged load.
If you're an avid mobile gamer, the Helio G90T in the Note 8 Pro will give you more FPS on heavy projects like PUBG or Genshin Impact on mid-settings. But if you value balance and no overheating, the Snapdragon 720G will be a more predictable partner. Optimizing games for Qualcomm processors is traditionally better, which affects compatibility with emulators and new applications.
⚠️ Attention: Helio processor G90T Redmi Note 8 Pro is prone to rapid heating.It is not recommended to play heavy games while charging the device to avoid trottling and battery degradation.
Cameras and quality of filming
Photographic ability is one of the main reasons for the popularity of the Redmi Note series. The Redmi Note 8 Pro has a 64MP core module (Samsung GW1). It was the first mass smartphone with such a matrix. It takes detailed pictures during the day, but processing algorithms sometimes sin overshark and unnatural color.
The Redmi Note 9 Pro also got a 64MP main camera, but with improved optics and software processing.The newer ISP (Image Signal Processor) in the Snapdragon makes it better to work with HDR and night mode.The wide-angle module here also got better, although the ultra-wide-angle 8MP camera remained pretty mediocre in both cases.
Secrets of Night Shooting
Video capture is possible in 4K resolution on both devices, but stabilization is software-based and runs mediocre.The front camera of 20 MP on the Note 8 Pro and 16 MP on the Note 9 Pro deliver a comparable result, although the newer model has a better portrait mode with background blur.
Autonomy and charging speed
One of the most significant improvements in the Redmi Note 9 Pro became the battery capacity, if in its predecessor it was 4500 The new model has a battery on it. 5020 This is a huge difference, which in real use gives additional 2-3 For users who are on the road all day long, it's a crucial factor.
Chargers are also different: In the box with the Redmi Note 8 Pro is a block of 18 watts, while the Redmi Note 9 Pro comes with a powerful adapter of 30 watts. Full charging of the more capacious battery of the new model takes about an hour and 15 minutes, which is a great indicator for this segment.
💡
For maximum life extension of a lithium polymer battery, try to keep the charge in the range of 20% to 80%. Avoid deep discharge to zero and being constantly on charge after reaching 100%.
The power efficiency of the Snapdragon 720G processor also contributes to autonomy. In standby mode and with easy use, the Redmi Note 9 Pro can last up to two days without recharging. The old model, despite its smaller battery, also performs well, but requires more frequent network connection when used actively.
Software and updates
Software support is an aspect that is often overlooked when buying, but it is critical to security and stability.The Redmi Note 8 Pro came out with Android 9 and received updates to Android 11 (MIUI 12/13).At the moment, the cycle of major Android updates for it is complete, and it only gets security patches.
Redmi Note 9 Pro launched on Android 10 And it was upgraded to Android. 12 (MIUI 13/14). This means that the owner of the newer model has time and relevant system functions. MIUI Qualcomm platform is usually performed better, with fewer bugs.
☑️ What to check before buying a used smartphone
It is important to consider that newer versions of MIUI can be heavy on older processors. If you plan to use the phone for a long time, then a model with a margin of performance and more recent software will be more profitable in the long run.
