2-minute Review [Positives]
  • Decent looks and build quality - very similar to the Samsung Galaxy M31, with a a unibody polycarbonate design, and glossy finish on the back panel - the only major difference is the camera module which houses a triple rear camera
  • The plastic body keeps the phone feeling relatively lightweight at 188 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 and work very well
  • 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 M21's 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
  • Decent triple rear camera setup - a 48MP primary snapper, an 8MP ultra-wide lens and a 5MP depth sensor
  • In broad daylight, you'll get consistent, crispy shots with decent dynamic range and sharpness levels are respectable with the primary lens
  • 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)
  • Live Focus shots are quite good 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 M21 does a good job of separating the subject from the background
  • The 20MP selfie camera is quite good and takes detailed selfies (though, in low light, the quality goes down a notch and results are grainy)
  • Monster 6000 mAh 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
  • If you're someone who consumes a lot of content on their phone, the Galaxy M21 is a good phone for you, it has great AMOLED display, outstanding battery backup that will last you for days
  • Pristine design - the Realme 6 has a gradient finish with multiple streaks running down the back, converging at the bottom centre - it shines when light hits it, giving the phone a premium look
  • Trendy, modern hole-punch design at the front, which isn't very common at this price point
  • Compared to the Realme 5, the Realme 6 has a rounded, curvier back that makes it more ergonomic to hold
  • The side-mounted fingerprint scanner is quick and accurate
  • Face unlock is super quick and combined with raise-to-wake feature, makes for a seamless unlocking experience
  • Good, large 6.5 inches full-HD+ IPS display with thin bezels and new punch-hole camera - the colours and peak brightness of the screen are good
  • The display has a 90Hz refresh rate which helps the smartphone deliver a smooth experience - games that support 90Hz displays, like Alto's Odyssey, are particularly enjoyable to play
  • Software is one area where Realme has taken a big leap, the Realme UI is easy to use - it is also packed with features such as Digital Wellbeing, Focus Mode, Dark Mode, and Riding Mode among others - there are some exciting and useful features like Realme Dual-Mode Audio, which allows you to connect a Bluetooth and a wired headset at the same time to listen to music on the smartphone
  • Super snappy performance with the powerful MediaTek Helio G90T - the day to day tasks are a breeze on this phone, applications open quickly, RAM management is quite good, and multitasking is also handled well - the phone breezes through medium and high-level graphic-intensive games like PUBG, which runs smoothly
  • Good quad-camera setup at the back consisting of a 64MP primary camera, an 8MP Ultra-wide angle camera, a 2MP monochrome camera, and a 2MP macro camera
  • In daylight, primary camera captures some fine-looking shots with a good amount of detail and dynamic range, it is quick to focus and meter light properly in most scenarios - image processing does a good job at adding punchy-ness to the colours
  • The wide-angle camera is decent and offer a wide field of view which comes handy in tight places and capturing more area - warping on the edges is taken care of decently through software (though, the quality isn't as good as the primary sensor)
  • In low light, the camera takes good-looking shot - the Night Mode does a much better job in low light by stitching together multiple frames delivering a brighter overall result, shots taken with Night Mode have significantly better details (however, the quality dips slightly in low-light)
  • Selfies shot with the Realme 6 have good detail, and beautification is enabled by default, photos are good enough to be shared on social media - you can take portrait shots, panoramas and even time-lapse videos with the front camera
  • The new black and white monochrome lens helps take great monochrome portraits - this lens helps the main sensor grab a wider spectrum of greys, hence adding more richness and texture to portrait shots
  • Battery life on the Realme 6 is quite good with the 4300 mAh cell, manages to go on for over a day and a half before needing to be plugged in
  • The 30W fast charging is unheard of at this price and that too with bundled charger in the box - the phone gets to 65 per cent in 30 minutes and took a little over an hour to charge completely
  • The Realme 6 is a power-packed phone that's one of the most exciting offerings in its price segment - with segment-first features like a 90Hz display and 30W fast charging, it is one of the best smartphones money can buy in this price segment - the Helio G90T is a great performer, the quad-camera setup offers versatility, and Realme's UI is quite good too
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 M21'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 9 Pro and the Realme 6 are much better options that will handle gaming better than the Galaxy M21
  • Photos taken in low-light are average - focusing gets worse in low light and the extreme noise-correction makes images look like water paintings
  • Overall, the cameras on the M21 are decent, but there are better cameras available in this price bracket, including the Galaxy M31, which is just a tad bit pricier
  • Samsung Galaxy M11 falls behind in fast charging as competitors are offering close to 30W fast charging, the 15W on M21 feels low
  • Having said that, the Redmi Note 9 Pro and the Realme 6 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 Realme 6 or the Redmi Note 8 Pro that are probably the best phones for gaming in this segment
  • A bit thick at 9.6mm
  • The rear panel isn't glass, and could pick up minor scuffs and scratches (though, it's more durable and light-weight)
  • There are still several pre-loaded apps however - though most of these can thankfully be uninstalled
  • The macro lens doesn't excel at what it is supposed to do, the detailing of the images is low because of the meagre 2MP resolution (though, it help take closer shots of smaller subjects)
