2-minute Review [Positives]
  • Decent looks and build quality - very similar to the Samsung Galaxy M30s, with a a unibody polycarbonate design, and glossy finish on the back panel - the only major difference is the camera module which now packs a fourth camera
  • The plastic body keeps the phone feeling relatively lightweight at 191 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
  • 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 M31s' 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
  • Good quad rear camera setup - 64MP main sensor + 8MP wide-angle lens + 5MP depth sensor
  • Shots taken with the primary camera during daylight are quite satisfactory, images are detailed, especially the 64MP shots, and they showcase 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 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 M31 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 15W fast charging
  • Samsung has seen success with the Galaxy M30s, so it didn't want to fix what isn't broken, they upgraded the RAM, put in a fourth rear camera, and preloaded Android 10 - if you don't care for benchmark scores and just want a device that covers the basics and has great AMOLED display, has great battery backup and has a versatile set of cameras, the Galaxy M31 will do just fine
  • Rugged design, with top-notch fit and finish - one of the most solidly built phones in recent times - comes with a polycarbonate chassis instead of a glass finish more commonly seen in this price bracket these days - what that means is that it looks less premium, but at the same time will be much more durable over the long term
  • Excellent IR based facial recognition - which works in the dark too (like the iPhone X) - the unlock time is just 0.1ms - in fact it works so well, that you will likely end up not using the fingerprint sensor at all (which itself, works very well too, in case you do want to use it)
  • Very good 6.18-inch FHD+ 19:9 display - excellent brightness levels ensure that there are zero issues with reading the contents on the screen under harsh sunlight as well
  • 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 optimization - and now it also has an app drawer like stock Android (there are some preinstalled apps like UC Browser, Amazon, and Facebook, to Microsoft apps like Word and Excel, but all of these apps can be uninstalled if you don't need them)
  • And as is the case with all phones running Android 8.1 Oreo out of the box, the POCO F1 offers Treble, and POCO says it will honor the warranty for those users that tinker with custom ROMs - in fact POCO is actively encouraging the modding community to make custom ROMs for the phone - which means that (unofficial) Android updates will continue to be available for the phone for a long, long time to come
  • Top-end performance, backed by the scorching Snapdragon 845 - the speed here is right up there with the likes of the OnePlus 6, and other flagships - it delivers blistering performance day in, day out - coupled with a well optimized MIUI, you are going to get butter smooth performance all through
  • To further differentiate the F1, POCO has incorporating liquid cooling in the device, which is designed to boost sustained peak performance times - there's a vapor chamber next to the chipset that siphons heat and dissipates it over a wider area, preventing the phone from overheating during prolonged gaming sessions - what that means is you could play graphics-heavy games for hours on end, and the phone doesn't warm up in any significant amount
  • Good dual rear camera setup, with plenty of AI chops - photos taken in daylight come out with plenty of detail and high dynamic range - bokeh shots come out well too - and low-light shots are decent too - overall the camera is pretty close to that on the OnePlus 6 in overall quality (and the OnePlus 6 costs much more!)
  • Good front camera too - delivers some great vanity shots, and is surprisingly good in portrait mode, getting most of the edges right, and blurring out background beautifully
  • Video recording quality is pretty good too, with quality 4K and 1080p shots
  • Good call quality and dual VoLTE support
  • The speaker is one of the best you'll find at this price point, and the F1 gets loud — playing games and watching videos is a delight on this phone - a major reason for that has to do with the fact that the phone has Dirac HD Sound — a mainstay on Xiaomi phones in the past - the earpiece also doubles up as a secondary speaker
  • The F1 is in a class of its own when it comes to battery life, outclassing even the battery powerhouse Redmi Note 5 - thanks to the combination of the 10nm Snapdragon 845, the 4000mah battery, and well-optimized MIUI - you'll easily get two days' worth of use out of the F1
  • The F1 supports Quick Charge 3.0, and Poco is bundling an 18W charger in the box - it takes just under two hours to charge the device fully, and you'll be able to go from flat to a 50% charge in just under 30 minutes
  • Combine the excellent battery life + the excellent fast charging, there isn't a single flagship that comes close to the F1 in terms of battery life
  • On the whole, the Poco F1 gives incredible performance at an unbeatable price - nothing comes close - and some great devices like ASUS' ZenFone 5Z, and the OnePlus 6 start to look expensive in comparison (which is saying something) - the F1 is a durable all-rounder flagship that will serve you well in all areas - and it comes right now with an incredible value-for-money proposition
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 M31'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 8 Pro, the POCO X2 and the Realme XT are much better options that will handle gaming better than the Galaxy M31
  • Samsung Galaxy M31 falls behind in fast charging as competitors are offering close to 30W fast charging, the 15W on M31 feels low
  • Having said that, the Redmi Note 8 Pro and the Realme X2 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 POCO X2 or the Redmi Note 8 Pro that are probably the best phones for gaming in this segment
  • The polycarbonate design means that it definitely doesn't look quite as premium as the OnePlus 6, or the Zenfone 5Z (although what it lacks in looks it makes up for in durability, so it depends on what you value)
  • The display has fairly significant bezels around it, compared to the tall displays on other flagship phones
  • Low light performance is one area where it's not quite as good as the OnePlus 6 camera, since it lacks OIS
  • Like other recent Xiaomi phones, the Poco F1 does not support HD streaming from Netflix and Amazon Prime (the content is streamed at max 540p), due to a certification issue, so you might want to keep that in mind if you plan to use these services on your phone
