Ranked in these QuestionsQuestion Ranking
Pro Fastest, coolest charging solution to date in any phone
The Dash charging solution in the OnePlus 3T is significantly better than any other fast charging technology. While Qualcomm's Quick Charge causes phones to heat up, the OnePlus 3T has a proprietary charger that they can make work better with the 3T. This allows the 3T to charge faster, without heating the phone up than any other phone available today.
Pro Good build quality
Instead of the plastic clad phones of yesteryear, the OnePlus 3T is encased in a metal body this time around. While the design is remarkably similar to the HTC 10 (and HTC One M7 - M9), it feels solid and looks great.
Pro Fastest Android phone in 2016
Equipped with the Snapdragon 821 and 6GB of RAM, the OnePlus 3T is the best performing Android phones from 2016. As seen in PhoneBuff's real world speed test, the OnePlus 3T crushes the Galaxy S7 Edge, and handily beats out even the Google Pixel XL.
Pro Amazing battery life
The OnePlus 3T has a larger than average 3600mAh battery, which allows it to last the whole day every day. GSMArena gave it an endurance rating of 83h (1 hour of talk, 1 hour of video, 1 hour of web browsing, then idle until the battery dies), which is quite a bit better than most other phones.
This will only improve with Android Nougat which brings active Doze (the name for an android feature where the phone enters a hibernation mode when sitting idle for long periods of time).
Pro Lots of storage (up to 128GB)
Most phones (even expensive, high end phones) only come with 32GB of storage, but the OnePlus 3T starts at 64GB with an option to go up to 128GB. This should be more than enough for most people, even after considering that it doesn't have a SD card slot.
Pro Easy notification handling
The OnePlus 3T has a notification slider with 3 positions that toggles between all notifications, priority notifications, and do not disturb mode. This is very handy because you won't need to pull your phone out and turn the screen on to change the alert profiles anymore - you can do it from within your pocket.
Pro Great value
For the price of 440$, you are getting a phone that is on par with phones in the 600$-700$ range in most aspects.
Pro Great display
While it's 1080p resolution isn't up to par with the 1440p standard, the 5.5" Gorilla Glass 4 AMOLED panel is still amazing.
Con 1080p display
While this isn't a major bummer, with 1440p being the standard in most phones nowadays, having a lower resolution display can be a disappointment to some, especially with text not being as sharp.
Con Dash Charge adapter is expensive
The Dash Charge adapter could cost you up to 25 US$ which is kind of pricey.
