Pros
Pro Very good camera
In well lit scenarios, you'd be hard-pressed to find a better camera. The 13MP sensor has a dual tone flash as well as a f/2.0 aperture. In low light scenarios, it can introduce noise and over saturation, but results are still admirable considering the price. It is capable of recording 1080p video at 30fps, or 120fps slow-mo videos at 480p.
Pro Good performance
The Snapdragon 615 used is the second generation, improving performance over previous Snapdragon 615 processors. It scores 2656 in GeekBench 3 - a very respectable score, and handles just as well in games.
Pro Built-in themes
You can install a new theme on your phone through the built-in theme store, or download more themes. These change the color scheme in the system UI and icons.
Pro Good battery life
The 3210mah battery is large, and you'd be hard pressed to completely use it up in a day. The Snapdragon 615 chip which is used isn't the most efficient, and the screen takes up a good amount of power as well - the only things preventing this phone from having great battery life.
It even includes a quick charge feature (not Qualcomm's branded QuickCharge), which can deliver a40% charge in an hour or a full charge in 3 hours.
Pro Great display
The 5" 1080p display is very good for a phone that costs this little. The resolution is great, colors are vibrant and accurate, and viewing angles are great as well.
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.
Cons
Con Heavy Android skin
There is no app drawer which mean the home screen will be more cluttered, and instead of using the regular Android design elements you can see influences from the iPhone around the OS.
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.
