Design
- 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
- Incredibly fast and accurate fingerprint sensor
- 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
Display
- Bright, sharp AMOLED display
Software
- 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
Performance
- Breathtaking, and flagship-beating performance backed by powerful hardware and an astounding 6GB of RAM - now goes even one step better with the Snapdragon 821 processor (as opposed to the 820 on OnePlus 3), although the difference between the two will only be noticeable in the heaviest apps/games
- Excellent heat management - the phone doesn't get hot even when put under high stress levels
Camera
- 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 even better than the OnePlus 3 (which itself had one of the best front cameras on a phone) and now takes even sharper selfies, even in low light
Audio
- Decent loudspeaker, with good volume levels
- Excellent audio quality via headphones
Battery
- Excellent battery life, that goes one up even on the already good OnePlus 3 - comfortably 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
More
- On the whole, while the OnePlus 3 is easily one of the best and most well-rounded Android phones ever made, the OnePlus 3T takes it a step ahead, and makes a great phone even better
