Xiomi’s smartphones are known for affordability. The Redmi series enjoys to be one of the most popular smartphone brands in India. A few years ago, any smartphone enthusiast would quickly choose the Redmi Note series when recommending a worthy performance-oriented and affordable smartphone. But since then, the smartphone market has become much more staggered, fragmented, and confusing. Almost every other smartphone company is now trying to surf the “affordability” wave, putting pressure on Xiaomi and its sub-brand Redmi.So, with the overwhelming number of options now out there, is the recently launched Xiaomi Redmi Note 9 Pro.
Redmi Note 9 Pro/Note 9 Pro Max Specifications
Redmi Note 9 Pro Design
The new style statement lends the Redmi Note 9 Pro a much more premium and eye-catching appearance than previously launched devices in the series.
The Redmi Note 9 Pro, as well as the Max, is being made available in Glacier White, Interstellar Black, and Aurora Blue colors, and their names are well descriptive of the inspirations for these colors. Xiaomi India sent us the black variant, but I prefer perceiving it as a shiny gray color that appears blue in sunlight.
The square camera module is strikingly different from the linear camera arrays used by Redmi on previous devices. The camera module sits atop a thick platform, which adds a few extra millimeters to the thickness of the Redmi Note 9 Pro. The camera module’s square shape has a couple of glaring advantages over linear arrangements as seen on the Redmi Note 8 Pro. First, it allows the phone to sit on a flat surface such as a table more firmly without causing any wobble when you tap on the display. Second, it makes the camera more of a subtle element and less in-your-face. The obround ring that encloses the two cameras in the upper row reminds me of Bender, the robot from the animated series Futurama.
It is worth noting that the Redmi Note 9 Pro is bigger, thicker, and bulkier than the Redmi Note 8 Pro.
Redmi Note 9 Pro/Pro Max Display
The Redmi Note 9 Pro’s hole-punch display is designed to fascinate. It is not the first smartphone to feature a hole-punch LCD in this price segment – Vivo did it several months ago with the Z1Pro, and much more recently, several phones including the Redmi K30, POCO X2, Realme X50, and the Realme 6/6 Pro embrace the feature. However, the center-weighted hole-punch on the Redmi Note 9 Pro grabs your attention because it is tasteful and in line with the pro-symmetry and pro-balance design philosophy I mentioned earlier.
The display measures 6.67-inches diagonally. While it is identical to the POCO X2’s display in size, there’s a noticeable difference between the color profiles of the two panels. The Redmi Note 9 Pro’s display appears relatively cooler and more saturated than the POCO X2. Side-by-side, the Redmi Note 9 Pro’s display also appears to be lower in brightness and this is corroborated by the official specification pages of the two phones. While POCO claims a maximum typical brightness of 500nits for the X2, Redmi’s official listing says the maximum typical brightness value for the Redmi Note 9 Pro is 450nits, 10% less than on the POCO X2. Despite this, daylight legibility isn’t a challenge for me, but you will not be able to enjoy content on the display in their truest colors. A sunlight trigger appears to boost the brightness and the contrast of the display when direct light from a strong source falls on it.
The centered hole-punch is a novel and exciting attribute for some users, but the quality of the display is not exciting.
While competitors, primarily Realme as well as Xiaomi’s sister company POCO, are betting big on displays with higher refresh rates, Redmi is sticking to 60Hz refresh rate panels on not just the Redmi Note 9 Pro but also the Redmi Note 9 Pro Max. Therefore, you’ll miss out on a smoother scrolling experience, especially if you are comparing it to a gaming monitor or an acquaintance’s phone that supports that higher refresh rate mode. The 60Hz refresh rate may also be limiting for anyone considering to buy this for gaming. While the list of games that can run on frame rates higher than 60fps is currently small, we can expect to see more game developers embracing the feature over the year. In that scenario, Redmi Note 9 Pro users might be left out. If it’s any consolation, popular resource-hungry games like PUBG Mobile or COD Mobile might still not support higher FPS gameplay on mid-rangers such as this one.Widevine L1 certification following the updateWidevine L3 certification before the updateNetflix playback specifications before the update
Additionally, the display does not come with any sort of HDR certification. You do, however, get Widevine L1, but it is also stuck in a precarious position. During my review period with the Redmi Note 9 Pro, Full HD playback in OTT apps such as Amazon Prime Video and Netflix fluctuated for unknown reasons. In the DRM Info app, the Redmi Note 9 Pro shows contradicting results for the Widevine security level test. We checked with the Redmi team and they said that this is probably a bug and could be rectified with an OTA in the future.
To conclude this section, the display is overall satisfactory, and while the hole-punch may be a novel and exciting attribute for some users, the quality of the display is not exciting. It feels like a weak link in the otherwise strong stance that the Redmi Note 9 Pro shows.
Xiaomi Redmi Note 9 Pro/Pro Max: Performance
On of the performance front, the Redmi Note 9 Pro and the Redmi Note 9 Pro Max are powered by the Qualcomm Snapdragon 720G mobile platform, which was introduced only a few months ago. While the Redmi Note 9 Pro series is not the first device with this chipset – the Realme 6 Pro is the first device with the chip – it is the first device from Xiaomi or any of its sub-brands to have this chip. The Snapdragon 720G comes with a few minor improvements over last year’s Snapdragon 730/730G, and these include higher clock speed for the performance cores. Qualcomm has strategically named the chipset as well as the Kryo 465 cores – as opposed to Kryo 470 on the Snapdragon 730 series mobile platforms – even though they use the same Cortex-A76 and Cortex-A55 reference architectures from ARM. The chipset supports dual-frequency GNSS including India’s NavIC and Bluetooth 5.1 with aptX Adaptive.
Performance-wise, the Snapdragon 720G is on par with the Snapdragon 730/730G and even edges it out in certain cases.
We performed some standard synthetic benchmarks to determine the Redmi Note 9 Pro’s performance and how it benefits from the new mobile platform. Since the Redmi Note 9 Pro Max also comes with the same hardware, we can expect similar performance from it as well.
Starting with Geekbench 5, the cross-platform CPU-centric benchmark, we find that the Redmi Note 9 Pro puts up the best scores from within our test lot. It is almost neck-and-neck with the Realme 6 Pro, while also having a small advantage over the Realme X2 and the POCO X2, which are equipped with the Snapdragon 730G. Lastly, the Redmi Note 8 Pro (review) with a MediaTek G90T is left behind with the poorest performance in the bunch.
CPU Throttling Test
The Redmi Note 9 Pro does not overheat much – or at least, the heat is not felt much due to the glass sandwich design. Although Xiaomi does not explicitly talk about a vapor chamber or internal cooling, there is minor throttling on the phone. We used the CPU Throttling test app, which repeatedly runs multiple threads (20 in our test) written in C language over a period of time (15 minutes in our test) to check if the CPU performance is throttled to prevent overheating in the system.
After running the test app in three different scenarios – with adequate battery, with low battery, and while charging above 90% (which is when the charging rate curve starts to flatten out). We find that there is only minor throttling (6%) when there’s sufficient battery. In comparison, the performance is much lower when the battery is low – in our test, the peak performance falls by 47%. Furthermore, the CPU performance is throttled to 88% of the peak performance while charging.
On PCMark Work 2.0, which simulates day-to-day tasks like editing documents, photos, videos, etc. or browsing the web and scrolling within apps, we see results inconsistent with the last test. The Redmi Note 9 Pro scores the lowest whereas the Realme 6 Pro, with the same chipset, scores the highest. The only plausible explanation for this is that our Redmi Note 9 Pro unit comes with 6GB of RAM while all the other devices in the comparison utilize 8GB RAM.
How Can We Forgot Gaming?
To sum it all up, the Redmi Note 9 Pro and the Redmi Note 9 Pro Max are among the best performing devices in this price segment. You won’t experience any jitter or lag in daily usage. While gaming, the chipset currently supports the “Ultra” frame rate (40fps) on PUBG Mobile but lacks support for HDR gameplay. The culprit for this, however, is Qualcomm and not Xiaomi or Redmi. The performance can be overclocked with the PUB Gfx tool but it might lead to some instability and the settings reset every time you exit the game. On top of that, there’s a constant fear of being banned if Tencent determines it as cheating. COD Mobile, on the other hand, runs the “Max” frame rate (60fps) at High graphics settings and “Very High” frame rate at “Very High” graphics. In either of the games at the default max settings, there is no lag of any sort and the heat generation is also minimal. The Redmi Note 9 Pro and Redmi Note 9 Pro Max, ergo, are pretty good devices for mid-tier gaming.
Xiaomi has added a new Z-axis vibration motor on the Redmi Note 9 Pro series which results in quicker haptic feedback. There are different vibration profiles associated with different actions such as typing, navigation gestures, interactions with Quick Settings toggles, etc.
The vibration motor feels smoother than on the Redmi K20 Pro and might add a whiff of premium experience to the mid-range.
The Redmi Note 9 Pro and the Redmi Note 9 Pro Max come with the largest battery in the Redmi Note series ever. The 5,020mAh battery breezes through the day and outperformed my expectations. The big battery easily delivers a two-day-long backup on moderate usage. In my usage, the battery lasted for around a whopping 60-hour period (2 days, 10 hours to be precise) with a screen-on-time of 8 hours. In another scenario, I pushed the screen usage to about 15 hours (by binge-watching videos) with the screen brightness set to auto and the phone still lasted 22 hours in total. That is both impressive and exciting.
When it comes to charging, the 18W charger provided with the Redmi Note 9 Pro takes about 90 minutes to go from 10% to 90%. After the 90% mark, the charging slows down significantly and the smartphone takes another 40 minutes to get to the 100% mark. Using a 27W charger from Xiaomi does not yield any better results even though the chipset does support Qualcomm’s Quick Charge 4.0.
In comparison, the Redmi Note 9 Pro Max is expected to charge much faster, owing to the 33W charging support. Since we don’t have a review unit yet, it is not feasible to test the performance.
In terms of connectivity, the Redmi Note 9 Pro supports LTE-Advanced with 3x carrier aggregation and 4×4 MIMO, Wi-Fi 6 with 8×8 MU-MIMO, and Bluetooth 5.1. The list of LTE bands supported by the smartphone is small because the phone is only available in India but might expand with more international releases. Here are the bands it supports currently:
- LTE FDD：B1/3/5/8
- LTE TDD：B40/41（2535-2655MHz）
In addition to the wide range of Global Satellite Navigation Systems (GNSS) supported by the Snapdragon 720G on the Redmi Note 9 Pro, the phone supports India’s NavIC. For better and more accurate navigation, the phone also supports dual-frequency GNSS, supporting a wide range of signal configurations including L1+L5 for the US’ GPS and Russia’s GLONASS, E1+E5a for Galileo, and B1+B2a for BeiDou.
The screenshots above show that among other satellite systems, the Redmi Note 9 Pro is also capable of receiving L5 signals from Indian navigation satellites. You can also test the same on your device using the GPSTest and the GNSSTest apps.
12MP vs 48MP
The Redmi Note 9 Pro is a charmer when it comes to looks and its serene Aura Balance Design is bound to attract eyes. In terms of specifications, it is a visible upgrade over the Redmi Note 8 and also the Note 8 Pro – except on the camera front. In that sense, the Redmi Note 9 Pro Max feels like the truer upgrade, even though the only upgraded attributes are the 5MP macro camera on the back and the 32MP selfie camera on the Max. If the camera is not your primary reason to upgrade your phone, the Redmi Note 9 Pro can be an excellent choice, but the sheer number of options in this price segment may compel you to think a bit more before finalizing your decision.
The 4GB RAM variant of the Redmi Note 9 Pro is the most affordable Snapdragon 720G smartphone.
