2-minute Review [Positives]
  • All-metal body, and polished design, gives the phone a premium feel
  • Quick fingerprint scanner
  • Fingerprint sensor also has extensive gesture support for all kinds of navigation
  • The 5.5-inch full-HD Super AMOLED display on the Lenovo P2 is vibrant, with good visibility even under direct sunlight - text and images appear really sharp, and the screen size makes the device well suited for media consumption - viewing angles are decent, and colour reproduction is adequate
  • The Vibe Pure UI on top of Android in now relatively leaner with less bloatware, and includes plenty of useful functionality like Dual Apps mode, Knock to Light, VR mode, Wide Touch, and Secure Zone
  • The UI is also pretty smooth and fast for everyday usage
  • Overall the Lenovo P2 performs well when it comes to multitasking and general app performance, including games
  • Good call quality
  • Decent loudspeaker, though there is some distortion at higher volumes
  • Decent cameras overall, with fast focus speed, especially in good light
  • The 5100mAh battery is truly exceptional, managing to last over 2 days, even with heavy use - and 3 days with moderate use
  • Fast charging support is a huge advantage too, easily managing 30-40 percent charge in just 20 minutes - and the phone can be charged fully in less than 90 minutes, which is again impressive
  • Additionally, the left side also has a slider switch that Lenovo calls a "power-saving key", which toggles the Ultimate Power Saver mode - which dramatically extends the battery life by killing lots of features like cellular data connectivity and syncing - it could really come in handy in emergency situations
  • Overall with the great battery life, and the power management features, the phone is a very good prospect for power users who like to be online all the time without worrying about their battery level, or frequent travelers
  • 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]
  • A bit heavier than most others in its class, due to its massive battery - in everyday usage, you will be more comfortable when using it with two hands, especially when typing
  • The bundled earphones are pretty average
  • 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
