Our Opinion

The Xiaomi Redmi K20 (64GB) is a significantly better phone, but the Samsung Galaxy M30s (6GB RAM, 128GB) is slightly better value for money. Which phone should you buy? Depends on how much you want to spend! But if budget is not a constraint, we recommend the Xiaomi Redmi K20 (64GB).

2-minute Review [Positives]
  • Decent looks and build quality - with a a unibody polycarbonate design, and glossy finish on the back panel - quite similar to the M30 - the only major visual difference is that the triple camera setup gets a wider, rectangular module to house the LED flash and "48 megapixel" branding
  • The plastic body keeps the phone feeling relatively lightweight at 188 grams, which is mighty impressive for a phone packing a big 6000mAh 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+ (2340x1080) Super AMOLED Infinity-U 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 optimized for large displays like this
  • One UI also brings in other useful stuff, like a System-wide Night mode (which turns the background completely black, and looks great on the M30s' AMOLED display), and Always On Display option
  • Good, strong performance with the Exynos 9611 at the core (similar to Snapdragon 665) - everyday performance to high-end gaming - everything is handled smoothly
  • Good rear camera setup - 48MP main sensor + 8MP wide-angle lens + 5MP depth sensor
  • With the primary lens, you get bright and attractive photos in daylight conditions with vibrant colours and good contrast - dynamic range is also wide and noise is controlled
  • Switching to the wide-angle lens will offer a new perspective, letting you click a wider area at close range to the subject (it is best used in daylight, however, as wide-angle captures look grainy and noise indoors or in low light)
  • The dedicated Night mode can be used with the main camera - it comes in handy in low-light conditions, extending the shutter time to allow more light into the frame - making for some decent low-light photos
  • Live Focus does a decent job at separating the subject from the background, and giving good bokeh shots
  • The 16MP selfie camera too does a decent job when it comes to capturing selfies outdoors under bright light (though it starts to struggle indoors and in low light, offering softer selfies with a lot of grain)
  • Overall, the cameras on the M30s are good for the price bracket, even though they are not the best (that title is shared by Xiaomi and Realme phones)
  • 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
  • With the M-series performing well for Samsung, M30s is well-set to add to that success, delivering a good all-round package with one key differentiator - an incredible battery life - if that is one of your primary concerns in a phone, then the M30s is a no-brainer (if on the other hand you want the best camera or best performance for your buck, you can look at Xiaomi or Realme phones in this price bracket)
  • Xiaomi has gone big on the design front this time - the Redmi K20 has a glass back with one of the most evocative gradient patterns you'll come across on any phone today - it's both premium to feel, and stunning to look at
  • The gradient effect that kicks in under the right lighting condition is quite mesmerising
  • The front is modern and sharp too, with a 'full screen' notch-less display (the selfie camera is a 'popup' one)
  • Decent in-screen fingerprint sensor - reasonably quick and reliable
  • Excellent 6.39" AMOLED display - high brightness, HDR10, and notch-free
  • MIUI is one of the most refined and fluid Android UIs around
  • The K20 also adds the POCO Launcher on top of MIUI - which brings the Dark Mode and App drawer to the K20
  • Excellent, butter smooth performance backed by the new, powerful Snapdragon 730 (very similar in overall performance to last year's flagship Snapdragon 845, and a step above the Snapdragon 710) - everything from daily use to games is butter smooth, as expected
  • Great all-round camera experience on all three rear snappers, photo and video
  • Decent selfies too, from the pop-up front camera
  • Overall, this is now the best camera phone in the under Rs 25k price bracket - the overall quality and versatility you get are a notch above what the competition offers
  • Has a 3.5mm jack, that a lot of flagships these days tend to skimp on
  • Loud (single) downward firing speaker
  • Great battery life, with a 4000mAh battery and a very power efficient chip - you can get up to 2 days of use, from this beast
  • Fast charging support - the supplied 18W charger fills 45% of a depleted battery in 30 mins - a full charge takes about 100 mins
  • The K20 is an excellent 'close to Flagship level' device from Xiaomi that seems set to disrupt the mid-range market in India - along with the new Realme X, it offers an excellent high-end, modern experience, at a relatively low price - all ingredients of a likely blockbuster hit
2-minute Review [Negatives]
  • The power button and volumes are quite flush with the frame which means they lack that tactile, clicky feel
  • Lacks the premium finish of some of its competitors
  • Focusing is slow at times
  • Overall low light camera performance still feels lacking
  • Face unlock mechanism is a little clunky - you have to first wake the screen and swipe up for the camera module to engage (this might get sorted via a software update though)
  • One issue with MIUI in recent times is the ads in the interface - those are still there (though a little less intrusive) - and while there are ways to disable them, it's a technical solution that a lot of prospective buyers will not even be aware of
  • The pop-up selfie camera mechanism is a bit on the slow side
