One Plus 3T – Introduction

One Plus 3T is an amazing smartphone which carries the company’s spirit and “never settle” tagline. It is quite clear that One Plus increases their price for each smartphone since its first smartphone “One Plus One”.

The increase in price maybe due to increase in demand or increased investment in development, marketing, sales etc. Anyways, lets get down with details.


Similar to all other smartphones from One Plus, 3T is also a great looking device and is made out of a single piece of space grade aluminium. It weighs about 158 grams and measures 7.4 millimeters thick.

The body of 3T is designed with smooth round corners and is much similar to One Plus 3 with few upgrades like sapphire coating, camera bump and few to be noticed.

On the left side of the device, we can find volume adjuster and an unusual slide which we don’t normally see on Android smartphones. It is an Alert Slider which enables us to toggle three states – Silent, Do Not Disturb and Normal mode.

The right side of One Plus 3T, we see power button with SIM slot above it  and on the top of 3T there is absolutely nothing, it is just plain and not even secondary mic is placed there.

Bottom side of the device looks quite busy, it has USB type C port, 3.5 mm audio port, microphone and speaker.

Display, Battery and Network connectivity

Regarding the display of One Plus 3T, It features a 5.5 inch display screen with resolution of 1080 x 1920 pixels. The pixel density which is 401 ppi (pixels per inch) which is great and features optic AMOLED panel. The display is pretty good and contrast is excellent and is much brighter than other smartphones with similar pixel density.

Also the sunlight legibility is good and color accuracy is a big plus since after the critics for One Plus 3. The new color rendering model opted for One Plus 3T is sRBG.

Now coming to network options, 3T performs well here too. It supports dual SIM cards (nano SIM cards), supports LTE which comes with courtesy of Qualcomm’s Snapdragon 821 which is the current flagship chipset with Cat.6 (upto 300 Mbps speed) and also supports NFC (Near Field Communication).

Apart from these, other network options include all bands of WiFi, Bluetooth v4.2, FM radio, GPRS/ EDGE, HSPA, 2G, 3G, Type C USB port (version 2.0), GPS etc.

Battery of One Plus 3T is a big plus which sports a 3400 mAh. The firm has included Dash technology which pumps 20W of power into the device. This new technology eliminated the need for charging long time.

It was able to charge up to 60% from 0% in just 30 minutes of charging. It was able to deliver 83 hours of standby time, 8:43 hours of web browsing, approximately 31 hours of 3G talk time and 13:23 hours of video playback.


One Plus 3T runs on Oxygen 3.5.3 (based on Android 6.0 Marshmallow). Initially One Plus used CyanogenMod but had to leave it behind and thus Oxygen operating system was born. It is safe to say that Oxygen OS has played quite well and its current version if 3.5.3.

With Nougat rolling out, company says devices will receive Oxygen update within the end of the year or early of January, 2017 via OTA (over the air). It looks like Oxygen is aiming to bring vanilla Android experience.

It comes with a finger print scanner. Since finger print scanners are now a part of core android that is one thing less for developers to worry about. Apart from it the gesture options which you might have seen in its ancestors are kept alive.

The Oxygen launcher looks neat and clean with a feature called Shelf where you will be able to see whether, most used apps, contacts etc. You can plsy with it by changing the header image, add/ removing widgets and stuffs.

Also it is notable that if you don’t like Shelf feature you have an option to disable/ re-enable it. Remaining user interface like notification bar, icons etc are similar to previous device from One Plus with few tweaks.

Coming to performance, One Plus 3T also scores in this area as well. Since it is powered by Qualcomm’s Snapdragon 821 chipset which is the Qualcomm’s current flagship chipset, the performance is not an issue here.

3T is quite fast (overall) and below is a list of benchmark score,

One Plus 3T scored 4364 on multicore, 1890 on single core tested by GeekBench 4. On GeekBench 3, it scored 5956 (multicore) and 2560 (single core). On AnTuTu 6 3T was able to get 165097, 3328 on Benchmark OS II and 2678 on Benchmark OS.

Moving on to graphics, the device is powered by Adreno 530 chipset. It was able to score 49 on GFX 3.0 Manhattan (1080p off screen), 48 on GFX 3.0 Manhattan (onscreen), 33 on GFX 3.1 Manhattan (1080p offscreen), 33 on GFX 3.1 Manhattan (onscreen), 20 on GFX 3.1 Car scene (offscreen), 20 on GFX 3.1 Car scene (onscreen), 36958 on Basemark X and 641 on Basemark ES 3.1 / Metal.

Sound (Audio effects)

As said earlier One Plus has adopted Google app suite but has not completely eliminated developing few basic applications. Gallery is one such app. You will be able to browse images or videos through Google Photos but also you can use Gallery to browse stuff.

Again for music playback there are two options, one is using Google Music and another is built in music app by Oxygen. The quality of the audio is good and clear. It produces clear sound effects when connected to external amplifier (even at high volumes).

But adding headset degrades the audio a little bit and introduces few distortions. Apart from that the overall performance is good.


The camera options of One Plus 3T includes a 16 MP primary camera and 16 MP front snapper. The rear camera performs great and utilizes Sony’s IMX298 sensor and is equipped with LED flash light with OIS-enabled. The camera has aperture of f/2.0 and 1.12 µm pixel size.

Regarding the front camera, One Plus decided to upgrade 8 MP camera (found in One Plus 3) to 16 MP in 3T. The selfie camera also performs moderately. The front camera does not come with LED flash. The features like HDR, Panorama mode, Oxygen OS’s HQ mode are performing quite well without any major issues.

Picture quality of rear camera is superb and front camera is okay but don’t expect the front snapper to perform great (but again One Plus never really performed well in selfie option is the past too, so…)

Coming to video performance, It is no surprise that 3T equipped with Snapdragon 821 chip (has high horse power) can deliver 4K video recording. The user interface of video recorder is as simple as its photo counterpart. It records videos at rate of 55 Mbps bit rate with accurate colors, high contrast and decent dynamic range.

The frame rate is 30 fps (frames per second) which is consistent and smooth. We can also record videos at 1080 pixels at 30 fps and also at 60 fps. Overall the camera options performs well.


Since 2014 when One Plus first launched its One Plus One they have come a long way which now has a huge user base and many are eagerly anticipating for more smartphones from One Plus.

The One Plus 3T has two variants 64GB and 128 GB. The price of 64 GB version is INR 29,999 rupees and 128 GB goes for INR 34,999 rupees and is about to launch on 14th December, 2016.

To conclude, 3T scores on all areas like performance, hardware, design, camera, audio quality etc. Thus I feel that at this price point (higher than its previous smartphone) what the smartphone offers is pretty high. So if you are planning on purchasing you can go right away and pre-order.
