2-minute Review [Positives]
  • Excellent build quality
  • Premium, high-end aluminum unibody design that gives the phone a truly elevated aesthetic compared to its predecessors
  • Super sleek at 7.35mm
  • Chamfered details around the display and charging port catch and reflect light to add to the looks
  • OnePlus' useful notification toggle is carried over from the previous OnePlus device, and is handy as ever
  • Bright, sharp AMOLED display
  • Oxygen OS UI keeps things nice, simple, and close to stock Android, is quite stable, and adds useful touches like the "shelf" homescreen, as well as handy customization options for power users - overall it works very well, and doesn't include any bloatware
  • Breathtaking, and flagship-beating performance backed by powerful hardware and an astounding 6GB of RAM
  • Excellent heat management - the phone doesn't get hot even when put under high stress levels
  • Very good camera, that compares well with the top flagship phones
  • Camera interface is fast, minimalistic, and intuitive
  • Support for 4K video, as well as time-lapse and slow-motion movies
  • Front camera is excellent too
  • Good battery life that is helped by good software optimizations - lasts the whole day even with heavy use
  • Super quick charging battery (OnePlus calls it "Dash Charging") that can completely charge the phone from 0 to 100% in a little more than 1 hour, beating other "quick charging" phones by a good margin
  • Incredibly fast and accurate fingerprint sensor
  • Decent loudspeaker, with good volume levels
  • Excellent audio quality via headphones
  • On the whole, the OnePlus 3 is easily one of the best and most well-rounded Android phones ever made, and the fact that it manages to be so at a price well below current flagship devices, makes it nothing short of exceptional
  • Premium build quality
  • All-metal unibody design
  • Brilliant, massive 6.4-inch screen that gets good marks on image quality, sharpness and brightness
  • Lively and simple Xiaomi interface, that is comfortably on of the better Android UIs around
  • Very good speed/performance for the class - and a notch above the Mi Max, because of the higher RAM and the newer processor
  • Wired audio quality is perfect - loud and with very little distortion
  • Fast fingerprint scanner
  • Good call quality
  • Astounding battery life, easily one of the best ever on a smartphone, and with particularly great web browsing times - easily lasts 2 days of active use
2-minute Review [Negatives]

No Major Negatives!

  • The phone's enormous size makes it hard to use one-handed
  • It's also heavy and will stick out uncomfortably in your pant's pocket
  • Given the gigantic size, the phone is primarily targeted at those users who consume a lot of media on their device, or want a combined phone-tablet - for more regular users the compromise of a difficult-to-handle size might not be worth it
  • Average sunlight legibility on the display
  • Loudspeaker performance could have been better
  • Average front and rear cameras, that could have been better especially in low light conditions
