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
  • Sturdy, tried-and-tested design
  • Curved back makes it comfortable to hold
  • Water-resistant P2i coating, similar to the Poco F1
  • Excellent, large, 'notch' display - it has superb contrast, good brightness levels, and tiny bezels - one of the best displays you will get in this price bracket
  • MIUI is one of the better, more refined, and more optimised Android UIs around, and is packed with many features and customisation options
  • There is also an option to switch to fullscreen navigation gestures instead of the on-screen Android navigation buttons
  • Solid mid-range performance - backed by the Snapdragon 636 which is still very good for the class
  • Excellent set of dual rear cameras at the back, which improve upon the already very good cameras of the Redmi Note 5 Pro
  • The rear cameras perform well regardless of the conditions you’re shooting in - Low light, artificial light, portrait shots, landscapes, it’s got you all covered
  • Very good set of dual cameras on the front as well - selfies taken with the Redmi Note 6 Pro have good details, and the edge detection in portrait mode is good too
  • Overall, the Redmi Note 6 Pro is now arguably the best camera experience under Rs. 20, 000
  • Excellent battery life with a 4000mAH battery pack
  • Has an interesting Wi-Fi pass through feature that lets your phone act as a Wi-Fi repeater
  • Thoughtful anti-rust coating inside 3.5mm audio jack and micro USB port
  • The Redmi Note 6 Pro again ticks all the right boxes for a best-seller in its class and price segment, continuing a tradition of the Redmi Note line in terms of excellent value for money
  • If you want a very good all-rounder with best camera in the mid-range, you need to look no further
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
  • The power and the volume buttons are both on the right - the power button is easy to hit, but the volume buttons need a bit of a stretch to reach
  • While the design is sturdy, it's also now a bit boring, with a lot of great looking phones now available in the budget segment
  • One of the issues with MIUI in recent times has been the annoying ads in MI's own apps, and that still continues with the Redmi Note 6 Pro (these can be disabled but it's a complicated procedure)
  • If you are a heavy gamer though, then the Redmi Note 6 Pro is no longer the best performer for it's price segment (like the Redmi Note 5 Pro was) - you will want to look at the Mi A2 or Realme 2 Pro instead
  • Video recording on the Redmi Note 6 Pro is decent but maxes out at 1080p which is a bit disappointing, considering that other smartphones in this price range are capable of 4K video recording
  • The phone also has support for Qualcomm Quick Charge 3.0 but Xiaomi only ships a 10W charger in the box - you will need to buy a quick charger separately to enable fast charging
  • Uses the outdated microUSB port, instead of a modern USB-C port
  • Having said that though, it's not quite a clear, outright winner as the Redmi Note 5 Pro was, simply because of the much tougher competition in this segment now - there is the Realme 2 Pro (has a much better take on how a notch should look like, and is more powerful with a SD660), the Xiaomi Mi A2 (No notch, Android One, all-metal design, SD660), Asus Zenfone Max Pro M1 (better battery, arguably better value for money), and the Motorola One Power (Android One, better battery) - so all in all, there are lots of good choices around
