2-minute Review [Positives]
  • Beautiful, polished, luxurious design - with a lot of attention to detail
  • The curved back and sides make it comfortable to hold
  • Nice, compact size
  • Dust Proof and Water Resistant
  • Beautiful, high-end display, with near-perfect color accuracy
  • The new "always-on" display feature is a nice touch, and takes the hassle out of checking out the time
  • Top-notch, chart-leading performance backed by the powerful hardware
  • Samsung's Touchwiz UI over Android is now even lighter, and has less bloat
  • Brilliant, awesome, fast camera, with OIS, that does well even in low-light conditions
  • Very good battery life
  • microSD storage slot
  • Quick charging, and wireless charging support
  • Good call quality
  • Very good audio quality
  • Very good, premium design, with top-notch metal construction
  • The overall form factor and weight remain quite ergonomic
  • Very good, balanced display - good responsiveness, brightness levels, and sunlight legibility
  • Runs clean, clutter-free and simple stock Android out of the box - and comes with the 'Android One series' update promise!
  • Strong, dependable performance, powered by a power-efficient Snapdragon 625 - running on stock Android eliminates some of the overheads on the processor and the phone presents a super smooth and lag free experience on general day-to-day things - it’s solid and will suffice for most except the most demanding of users
  • Good, solid dual-camera setup - Xiaomi’s stereo mode is its take on Apple’s “portrait mode”, and its task is to blur the background - the final effects are commendable most of the times - sometimes even better than much more expensive phones like the OnePlus 5 - making it easily the best dual camera system on a budget
  • Even in auto mode, the Mi A1 takes rich images with good levels of detail and colour saturation
  • There is also a very effective pro mode which even allows the user to individually choose between the wide angle camera and the telephoto lens - making for a very compelling camera package
  • Xiaomi also offers 2x optical zoom with this device - and the results are quite good
  • Video recording is decent too - it can shoot in 4k, and has time lapse and slow motion modes
  • The front 5-megapixel camera for selfies is decent too, though nothing exceptional
  • Good audio quality and volume via both headphones and the speaker
  • Good, dependable battery life - comfortably lasts a work day
  • Takes about 2 hours to charge fully - which is a decent charging speed
  • On the whole, if you are only concerned about performance and battery life, then the Redmi Note 4 may be a better choice, and if you care most about low light camera performance, then the Moto G5S Plus is at the top of the pack, but for an overall dependable phone with a dual camera setup, and stock Android experience, the Mi A1 is a brilliant choice
2-minute Review [Negatives]
  • The shiny metal-and-glass back is a smudge magnet
  • The performance is solid and dependable but not the absolute best in this price bracket - that status belongs to the likes of the Redmi Note 4
  • The camera is quite good in daylight conditions, but falls behind in low light prowess compared to say the Moto G5 Plus or Samsung Galaxy J7 Max - low light photos can sometimes be blurry and they take considerable time to process
  • Battery life is again strong, but not the best in this price bracket - that is again a position that's held by Xiaomi's Redmi Note 4
