2-minute Review [Positives]
  • Modern, trendy looks with minimal bezels
  • Textured power button comes handy while pulling out the phone from your pocket - you precisely know which button to press
  • You can trigger the camera by double pressing the volume down button
  • The fingerprint sensor at the back is easy to reach and unlocks the device almost instantaneously
  • Bright, vivid 5.65 inch display with a HD+ resolution of 1440 x 720 pixels and a tall, modern 18:9 aspect ratio - which basically allows for more screen real estate in a compact form factor
  • Infinix has customized the Android operating system with a light skin called XOS 3.0, which brings a tweaked icon and launcher system, apart from features such as dual accounts, and a file sharing service - it all works reasonably well
  • Good day-to-day performance, thanks to the solid Snapdragon 430 SoC - basic tasks such as calling, social networking, clicking pictures and running multiple apps are smooth, and games are also handled reasonably well
  • Good selfie camera, easily one of the best in the budget segment - and arguably better than the previous selfie camera leader in this segment, the Redmi Y1 - the camera is really quick to focus on the subject, and then layers the picture with beautification stuff to give you a crisp and beautified selfie - the beautification seems natural and and it isn’t as aggressive as that of its Chinese rivals - there is also a dual LED flash at the front to capture selfies in low-light, which is a great addition
  • Rear camera is decent too, though not anything special like the selfie camera
  • Very good battery life - can last up to two full days of moderate use (again going one up on the Redmi Y1 which is its primary competitor)
  • On the whole, the Infinix Hot S3 is one of the more impressive all-rounders in the budget segment, and will provide strong competition to the Xiaomi phones that otherwise dominate this segment
  • 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 speaker placed at the bottom could have been better - it is quite easy to cover the speaker and the overall sound profile is somewhat flat
  • 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
