2-minute Review [Positives]
  • Unique, flashy rear design - the polycarbonate back has a thick etched strip running through the middle with large Poco branding towards the bottom which shines in iridescent colours when light hits it
  • The front has a sleek look with just a single punch-hole camera in the middle-top and thin bezels
  • The Poco X3 is well-built for a phone at its price
  • The side-positioned fingerprint scanner is easy to find, very responsive, and accurate
  • There’s also IP53 rating for dust and water resistance
  • Vibrant and crisp 6.67-inch IPS LCD screen - the expansive canvas with smooth transitions and rich colours with high refresh rate make it one of the best in this segment
  • The 120 Hz refresh rate is exclusive to Poco for this segment - it makes the UI very quick and responsive and general content and scrolling on the display looks smooth
  • HDR10 support for content and sites like YouTube while Widevine L1 brings high-res OTT streaming
  • Poco's UI is identified as Poco Launcher as well as MIUI in different parts of the UI - MIUI has always been one of the most refined Android UIs out there, and continues to get even better - it offers a good combination of aesthetics, useful added functionality, lots of customizability, and optimisation - everything is neatly categorized and colour coded for easier access
  • Excellent performance for the price from the new Snapdragon 732G SOC - it raises the bar in terms of how smooth budget phones can be - regular usage like scrolling pages, switching between apps is extremely fluid and heavy games like COD: Mobile can also be cranked up to higher graphics or frame rates for a respectable performance
  • Good quad cameras for the price - a 64MP primary snapper, a 13MP ultrawide shooter, followed by a 2MP macro cam and a 2MP depth sensor
  • The default 16MP photos from the main camera are excellent for this class - there is enough detail, high contrast, and commendable dynamic range - the colours are on the warmer side, but other than that the Poco X3 performs splendidly for its price
  • The ultrawide photos are quite good for a mid-ranger - they are quite detailed, the colours are nice and there is a reasonably wide dynamic range, the lens distortion correction is decent
  • The macro camera is decent for the occasional snap of a flower or bug
  • The portrait shots are pretty detailed - the Poco X3 is a capable portrait shooter with proficient subject separation and natural-looking blur
  • The low-light photos from the camera are decent, with enough details and light - the night mode brightens the whole scene and restores the highlights, the photos look great on the phone's screen and in low resolution on social media
  • The 20MP samples from the front camera present enough details, the colours are nice, and the contrast is excellent - portrait selfies are available and are decent
  • Video recording is good from both primary and ultra-wide cameras - electronic stabilization is available for the cameras
  • Good set of stereo speakers - the speakers get very loud with good enough bass
  • Excellent battery life from the 6000 mAh cell - the battery can last a whole day with heavy use, with light to moderate use it can be stretched for the second day
  • Very good fast charging from the 33W fast charger - it takes little over an hour to charge the phone completely
  • The Xiaomi Poco X3 is one of the best budget smartphones in its segment - it crams in a huge battery, solid screen, good cameras, and excellent performance for an unbeatable price, add in the great audio setup and it makes for a fantastic package
  • Sleek, classy design - the Galaxy M31s 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, a first for the M-series
  • It has good ergonomics and feels comfortable to hold and operate
  • The side-mounted fingerprint scanner is quick to unlock the device
  • Vivid, crisp and punchy 6.5-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 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 M31s' AMOLED display), and Always On Display option
  • Decent performance with the Exynos 9611 at the core (similar to Snapdragon 665) - the phone is good for basic operations
  • Good quad rear camera setup - 64MP main sensor + 12MP wide-angle lens + 5MP depth sensor + a 5MP macro camera
  • 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 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 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 M31s 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 25W fast charging - the phone takes around 2 hours to charge the battery completely, which is decent
  • Consider the Galaxy M31s for its vivid display, capable optics and stellar on-battery time
2-minute Review [Negatives]
  • A tad bit too bulky, measuring over 10mm and weighing over 225 grams
  • Brightness could have been better for direct sunlight use
  • There are still at least a dozen unnecessary apps pre-installed, though most of them can be uninstalled
  • The Galaxy M31s feels hefty at 9.3mm thickness and 203g weight (though, it's worth it for the 6000 mAh battery it packs)
  • However, it is an old chipset and heavy gaming and multi-tasking are taxing for the phone - the POCO X2 and the Realme 6 Pro are much better options that will handle gaming better than the Galaxy M31s
  • Look elsewhere if performance and gaming capabilities are your primary deciding factors - the phones like Realme 6 Pro and Redmi X2 are better equipped to meet your requirements in the performance segment
