2-minute Review [Positives]
  • 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
  • Beautiful, 'shimmering' rear (plastic) panel, and a modern, notch-less 6.5-inch OLED screen - easily one of the best looking phones in this price bracket
  • The notch-less display spans almost edge to edge, with a pop-up selfie camera mechanism (which is quite something to have, in this price bracket)
  • Fairly fast in-display fingerprint reader
  • The pop-up camera on the Realme X has a very quick ejection and retraction mechanism, which makes face recognition work pretty seamlessly too
  • Very good 6.5-inch OLED screen - colors are lively, with deep blacks
  • The lack of a notch really helps make the screen appear immersive, and consuming content on the screen is a pleasure
  • ColorOS UI is now much more streamlined than before - there’s also now an app drawer, and a useful shortcut menu accessed by swiping from the sides
  • The gesture navigation is nice and intuitive too
  • Thankfully, it's not ad-strewn either, like some of the recent phones from Xiaomi
  • Very good performance backed by the powerful Snapdragon 710 chipset - everything from daily use to high-end games is smooth
  • GPU performance is an especially strong point of the Snapdragon 710, so if you are into gaming, the phone tends to comfortably outperform rivals
  • Very good set of dual rear cameras (48MP+5MP) and front camera (16MP)
  • Good overall image quality in daylight, and fairly good quality in low-light as well
  • Night mode is pretty effective too
  • Very good portraits
  • Pretty great selfies too, from the 16MP front camera
  • Realme’s EIS does a solid job of stabilization during videos at up to 1080p/30fps
  • Support for 4K video recording (without EIS though)
  • Overall, the Realme X is among the best camera setups of this price bracket, comparable to the excellent cameras on the Redmi Note 7 Pro and the Realme 3 Pro
  • The Dolby Atmos-boosted speaker sounds pretty rich and gets fairly loud
  • Good battery life with a 3750 mAh cell - you will comfortably get a day of use, even with heavy usage
  • The class-leading VOOC fast-charging nicely complements the long battery life - it fills a completely depleted battery in 1:18h and it's at the 50% mark 30 minutes into it - which are some excellent numbers
  • The Realme X looks like an incredible value package, no matter how you look at it, and will inevitably disrupt its price bracket in a big way - what you get is top-end specs, a 'full screen' AMOLED display with a pop-up selfie camera, very good performance, an excellent set of cameras, and super fast charging - you can't ask for more
2-minute Review [Negatives]
  • 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
  • ColorOS still has some bloatware though, and is not quite as clean/simple as stock Android
