2-minute Review [Positives]
  • Decent looks and build quality - very similar to the Samsung Galaxy M30s, with a a unibody polycarbonate design, and glossy finish on the back panel - the only major difference is the camera module which now packs a fourth camera
  • The plastic body keeps the phone feeling relatively lightweight at 191 grams, which is mighty impressive for a phone packing a big 6000 mAh battery
  • It also feels great to hold with a seamless curved panel that meets the display up front
  • Modern, Infinity-U front - bezels around the screen are slim, except for a slightly thick chin - you still get around 90 per cent screen-to-body ratio, which is great
  • Fingerprint sensor at the back is easy to reach
  • Gorgeous, 6.4-inch FHD+ Super AMOLED display with excellent viewing angles, and brightness levels - easily one of the best displays in the price bracket
  • It also comes with "Widevine L1" certification, which helps stream content in crisp HD resolution
  • Blacks are deep on the AMOLED display, which looks good with Night mode enabled
  • Samsung's OneUI is today one of the more clean, refined Android UIs that's especially well optimised for large displays like this
  • One UI also brings in other useful stuff, like a System-wide Dark mode (which turns the background completely black, and looks great on the M30s' AMOLED display), and Always On Display option
  • Decent performance with the Exynos 9611 at the core (similar to Snapdragon 665) - the device is fairly quick to load up apps - multitasking is a breeze
  • Good quad rear camera setup - 64MP main sensor + 8MP wide-angle lens + 5MP depth sensor
  • Shots taken with the primary camera during daylight are quite satisfactory, images are detailed, especially the 64MP shots, and they showcase good dynamic range
  • The ultra-wide sensor, like on any budget phone, is a good addition - it takes social media-worthy images in great lighting conditions (in low-light, the quality dips and pictures look grainy and noisy, wide-angle shots also have barrel distortion at the edges)
  • Photos taken in low-light looks good - switching to Night mode helps reduce grain in the output and further improves image quality
  • Live Focus shots are quite impeccable and the camera app does give you the option to set the level of blur before taking a shot - edge detection is very good and the Galaxy M31 does a good job of separating the subject from the background
  • The macro camera takes decent shots outdoors (though, the quality dips when indoors and the output is restricted to 5MP in resolution)
  • The 32MP selfie camera is quite good and takes detailed selfies (though, in low light, the quality goes down a notch and results are grainy)
  • Overall, the cameras on the M30s are good for the price bracket, even though they are not the best (that title crowned to the POCO X2)
  • Monster 6000mAh battery delivers an incredible 2-3 days of usage easily, making for one of the largest battery life smartphones currently available
  • Supports 15W fast charging
  • Samsung has seen success with the Galaxy M30s, so it didn't want to fix what isn't broken, they upgraded the RAM, put in a fourth rear camera, and preloaded Android 10 - if you don't care for benchmark scores and just want a device that covers the basics and has great AMOLED display, has great battery backup and has a versatile set of cameras, the Galaxy M31 will do just fine
  • Fresh, bright and vibrant design, with a very shiny, reflective rear panel - you'll see light play across the surface when using this phone, giving the feeling of depth
  • The distinctive new camera bump design plays into the theme of symmetry - this is a nice design touch that sets the Redmi Note 9 series apart and make this phone and its siblings recognisable
  • The front of the phone looks modern and definitely defies expectations for its price category
  • Fingerprint sensor is integrated into the power key and it is extremely fast at unlocking the phone
  • Xiaomi's trademark infrared emitter is on the top, and can be used to control several home appliances
  • There's also a notification and charging LED hidden in the earpiece, a rarity to find in modern smartphones
  • Bright, crisp and large 6.67-inch IPS display with a tall 20:9 aspect ratio - the panel delivers punchy and vibrant colours and the large screen work nicely for consuming videos and games
  • MIUI is one of the more refined and smooth Android skins around, and has a lot of customisation/theming options - there’s ample features for power users - from gestures to the ability to switch around button layouts as well as a robust home screen customisation experience, you can really make the phone your own
  • Class-leading performance for the price backed by the snappy Snapdragon 720G - the Redmi Note 9 Pro is more than powerful enough to handle anything from basic calls and messaging all the way up to heavy 3D gaming, with no trouble whatsoever, multitasking is also smooth and trouble-free
  • Decent quad cameras for the price - a 48MP primary shooter, an 8MP ultra-wide angle lens, a 5MP macro camera and a 2MP depth sensor
  • In daylight, the primary camera takes reasonably good shots - Xiaomi has opted for very natural-looking colour science, the colour temperature and white balance are spot-on which is very good to see and the dynamic range isn’t too bad either (though, there is a certain softness to images, which can be fixed with a software update)
  • The ultra-wide angle mode works well to capture a wide frame without much effort and the quality is decent
  • Xiaomi has done a particularly good job at optimising the portrait mode and the phone does a fantastic job at edge-detection, creating a natural-looking blur
  • The macro camera deliver much higher quality shots than from most other 2MP macro cameras
  • The 16MP front camera is fairly good in the daytime as well as at night - details are good, and portrait shots had nicely blurred backgrounds
  • Very good battery life with the 5020 mAh battery - with ordinary use, the Redmi Note 9 Pro easily lasts through a full day and nearly half of the second day before needing a recharge
  • Decent fast charging with the 18W fast charger in the box, takes nearly 2 hours to fill the phone completely (though, this isn't the fastest charging phone and the Realme 6's 30W charging is much better)
  • The Redmi Note 9 Pro succeeds at delivering value, a decent camera, class-leading internals and beautiful design for the low price is certainly tempting - if flat-out performance at a low price is what you want, the Redmi Note 9 Pro delivers the best bang-for-the-buck
2-minute Review [Negatives]
  • The power button and volumes are quite flush with the frame which means they lack that tactile, clicky feel
  • Design feels a bit dated and underwhelming, there is no spark in Galaxy M31's design as we see in other brand's phones like Xiaomi and Realme
  • However, this is an old chipset and heavy gaming isn't best on this phone - the Redmi Note 8 Pro, the POCO X2 and the Realme XT are much better options that will handle gaming better than the Galaxy M31
  • Samsung Galaxy M31 falls behind in fast charging as competitors are offering close to 30W fast charging, the 15W on M31 feels low
  • Having said that, the Redmi Note 8 Pro and the Realme X2 will still offer you more bang for your buck overall and when it comes to intensive tasks like gaming, you’ll be better off choosing the POCO X2 or the Redmi Note 8 Pro that are probably the best phones for gaming in this segment
  • At 8.8mm thick and 209g in weight, the Redmi Note 9 Pro is bulky and unwieldy
  • It is a standard 60Hz panel and doesn't have a high refresh rate - this is a missed opportunity that puts the Redmi Note 9 Pro on the back foot compared to its peers
  • It still continues to pack a lot of bloat though - you get many pre-installed applications with wide-ranging requirements for user permissions
  • Low light photography is average, images are grainy with digital artefacts and splotches creating a nearly unusable shots
  • Overall, this is not the best camera setup at this price and this time Realme has done a better job which with its Realme 6 which offer better cameras at this price
  • However, the Realme 6 out-specs the Redmi Note 9 Pro with its high refresh-rate 90Hz display panel, as well as the inclusion of a 64MP camera that genuinely takes better images, and the phone supports faster 30W charging as well
