Despite being cheaper than other flagship phones, its raw performance power is on par or even better than its competitors. It can run multiple background tasks and even the most demanding games and apps without any stutter, due to its Snapdragon 835 chipset and Adreno 540 GPU — the most powerful GPU currently available for Android devices. It also has one of the highest RAM for mobile devices: the 64GB version has 6GB of RAM while the 128GB versions sports 8GB of RAM. It is highly unlikely that you will run into problems like application instability, stuttering, or crashing, due to insufficient specs.

The biggest change from the OnePlus 5 (and even earlier OnePlus models) is the screen. The 5T boasts a large 6.01-inch FullHD AMOLED display with a 18:9 aspect ratio that follows the trend of newer smartphones with elongated screens.

Even though it has a 1080x2160 resolution and 401ppi pixel density, it does not mean that the screen on the OnePlus 5T is poor, quite the contrary. The AMOLED panel offers bright and lifelike colors even though images are not as sharp as some other competitors.

The built-in 3,300 mAh battery can keep the phone alive throughout the day, with moderate usage. If you are a light user, the phone can even last for two days.

The phone has a dual-lens camera setup in the back. This setup allows you to zoom into objects up to 2x closer without losing image quality, like when using digital zoom. The portrait mode makes one of the cameras focus on the primary object/person, while the other camera unfocuses the background. This creates a bokeh effect that most phone cameras usually can’t achieve.

Photographers will appreciate the Pro mode that enables full manual control, as well as an on screen histogram and guidelines. It does, however, lack optical image stabilization, so you have to keep the phone really steady for long exposure shots. It also can’t capture high frame rate video.

The phone's casing is built from anodized aluminum, making it very durable and solid. The screen itself is also very resistant: having Corning’s Gorilla Glass 5, it is very hard to scratch and less vulnerable to impacts.

Even though the increased screen means that the fingerprint scanner had to be removed from the front and moved to the back, luckily it's placed in a central position which makes it easy to reach.
