2-minute Review [Positives]
  • Sleek, classy design - the Galaxy M51 seems identical to the Galaxy A51, with a glossy polycarbonate back design - giving it a premium look
  • The front gets a new trendy look with a hole-punch display, similar to the Galaxy M31s
  • The phone feels solid in the hand - the 'glasstic back' offers better grip, and it is not as slippery as other phones with a glass back
  • The side-mounted fingerprint scanner is quick to unlock the device
  • Punchy, vivid and massive 6.7-inch FHD+ Super AMOLED display - the display is one of the best in class panels with great colour reproduction and viewing angles
  • 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 Dark mode enabled
  • Samsung's OneUI is today one of the more clean, refined Android UIs that's especially well optimized for large displays like this one
  • 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 M51's AMOLED display), and Always On Display option
  • Very good performance from the Snapdragon 730G - the chipset and Samsung’s OneUI optimization could take anything that you throw at it, switching across apps, moving across the UI, multitasking, and opening multiple Chrome tabs, social media is a breeze - heavy games like Call of Duty run smoothly without any lag
  • Samsung has fixed the only major drawback it had in other M-series phones with average performance, and this time the Galaxy M51 has no issue taking on the competition in performance
  • Good quad rear camera setup - 64MP main sensor + 12MP wide-angle lens + 5MP depth sensor + a 5MP macro camera - the Galaxy M51 carries the same camera setup as seen on the Galaxy M31s
  • Shots taken with the primary camera during daylight are quite satisfactory, images are detailed, especially the 64MP shots, and they showcase the good dynamic range
  • The ultra-wide sensor, like on any mid-range 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 single take is a nice addition from the more expensive S20 series, it lets you capture multiple formats at once
  • 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 M51s are good for the price bracket, even though they are not the best
  • Mammoth, out of this world 7000mAh battery delivers an incredible 2-3 days of heavy usage easily, making the Galaxy M51 the largest battery life smartphones currently available
  • Supports 25W fast charging - the phone takes around 2 hours to charge the battery completely, which is decent
  • The Galaxy M51 brings very good value as its big battery, powerful cameras, and expansive display all help make a solid argument in the device's favour - the phone's Snapdragon 730G SoC also ensures that M51 offers enough in terms of raw power to help it tackle most things you throw at it
  • 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
  • Good quad camera at the back - a 64MP primary shooter, an 8MP ultra-wide angle lens, a 5MP macro camera and a 2MP depth sensor
  • Daylight shots from the Redmi Note 9 Pro Max turn out quite well - photos look sharp and the details are good - phone automatically enables HDR in appropriate situations
  • The Ultra-wide camera on the device offers a wider field of view with good quality images - wide-angle correction is implemented which prevents barrel distortion
  • 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
  • Macro camera is good for extreme close-ups - it captures very good details in good lighting conditions - the resolution is also higher at 5-megapixels than what you usually get from other smartphones
  • In low-light, the phone manages to keep noise under control and offer good images - with Night Mode enabled, the phone combines multiple exposures, the output is sharper, with much better detail, and objects in the shadows are more visible
  • The 32MP front camera is good - in daylight, you get sharp selfies - there is a portrait mode for the selfie camera as well, and it does manage to accurately separate the background from the subject
  • Video recording is decent as long as there's good light (though, in low-light the phone struggles to stabilise the footage and creates a shimmer effect)
  • Overall, it has one of the best camera performances in this price segment
  • 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
  • Excellent fast charging with the 33W fast charger in the box, takes nearly an hours to fill the phone completely, which is one of the fastest for this price
  • The Redmi Note 9 Pro Max is almost identical to it's younger sibling the Redmi Note 9 Pro, the only exceptions being the better cameras and faster charging - and if you value these features, it's worth spending the extra bucks on the Max
2-minute Review [Negatives]
  • The Galaxy M51 feels hefty at 9.5mm thickness and 213g weight - it is difficult to use for a longer duration for calls, streaming, or even gaming
  • The back of the Galaxy M51 is a fingerprint magnet - it can also get scratched easily since it is plastic
  • The display lags with a 60 Hz display, where competing phones like OnePlus Nord offer higher 90 Hz refresh rate
  • There's still great competition at this price and the OnePlus Nord has a lot up its sleeve with a newer processor, higher refresh rate display, and a best in class software
  • 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
  • However, if you are looking for a higher refresh display, you can consider the POCO X2 or the Realme 6, other specs are very similar
