2-minute Review [Positives]
  • Eye-catching colorway (plastic) design that is unapologetically flashy - this one is sure to turn heads
  • Dedicated Google Assistant button on the left side
  • Fast, accurate in-display fingerprint scanner and face unlock options
  • Beautiful, full HD 6.38-inch Super AMOLED panel - you will get punchy colours, deep blacks, and good sunlight legibility
  • It also has Widevine L1 support which means you’ll be able to stream videos in Full HD on video streaming platforms like Netflix and Prime Video
  • An interesting addition to the display on the Z1x is the new low brightness anti-flicker mode - when switched on, it reduces screen flicker to alleviate visual fatigue - particularly useful during late-night gaming sessions
  • Funtouch OS is an iOS-look-alike that is filled to the brim with customizations
  • It now also packs a useful Dark mode
  • There is also a dedicated PUBG feature (apart from the separate dedicated Gaming mode) that helps users make the most of their time while in the waiting room (Users can quit the application while waiting for the game to start and the game timer is displayed as a chat bubble in the UI)
  • Very good performance backed by the excellent Snapdragon 712 SoC that powered its predecessor - gamers too won’t be disappointed - the phone is more than capable of playing heavy games, at top graphics settings
  • Thermal management is pretty good too and the phone does not warm up easily
  • Very good set of cameras - front and back - you will get good detailed pictures in all lighting conditions
  • On the rear, the Z1x houses a triple-camera setup that consists of a primary 48MP sensor, an 8MP ultra-wide camera and a 2MP depth sensor
  • The pictures from the primary camera are visually appealing, generally saturated, and the colours pop
  • The wide-angle camera also takes images good enough to be shared on social channels
  • The camera application is also pretty comprehensive and houses a dearth of other features like Fun Video and AR stickers
  • There is also a a dedicated night mode present which does help in balancing exposure and getting a bit more detail in low-light scenarios
  • Portrait shots come out reasonably well - with good subject separation
  • The selfie camera is a 32MP snapper and takes really good selfies, especially in good light - there’s an AI Beauty mode too that lets you change just about any feature of your face - you can also play around with a bunch of different portrait effects and edge detection on these portraits is pretty decent too
  • Decent video recording quality - 1080p videos are stabilised well and colour reproduction is also decent (though focus lock can sometimes be jittery) - 4K videos, on the other hand, are a bit jerky
  • Overall, this is a very good camera setup for the price - perhaps only a shade behind the top camera phones of this price bracket - the likes of the Realme X and Redmi Note 7 Pro
  • Reasonably loud speaker (though, of course, as usually expected in this price range, it lacks depth)
  • Very good battery life with a large 4500mAh battery - you can easily get 1.5 days of use
  • Vivo has amped up charging speeds on the Z1x too, compared to the Z1 - the phone now supports 22.5W vivo FlashCharge that takes about 1 hour and 20 minutes to completely charge the phone from the 15% mark
  • Overall, Vivo Z1x presents itself as another excellent all-rounder alternative from the Vivo camp for the mid-budget segment after the successful Vivo Z1 Pro - it stands up to the likes of Realme X, Oppo K3, Redmi Note 7 Pro, the Samsung Galaxy A50 - all great phones on their own accord
  • 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]
  • On the bulky side
  • It still continues to be one of the more cluttered Android UIs however, and can prove to be overwhelming for someone coming from a lighter/stock UI
  • 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
