My Review of Oneplus 5T

The new Oneplus 5T is a souped-up version of the OnePlus 5. It comes with the current trend with an almost borderless display. OnePlus is bringing the update around Christmas. The two are the same in equipment and identical in design. There are two crucial differences. The display on the front is now larger with 6 compared to 5.5 inches and almost borderless. And on the back, OnePlus replaces the OnePlus 5 telephoto camera. There is a large aperture lens to enhance low light photography.

Our first impression of the OnePlus 5T is positive with high quality and performance. Very commendable is that the model update costs no extra charge! So you pay for the 5T as much as for the OnePlus 5. It means that the 64 GB version costs 499 euros and for 128 GB and more 8 GB RAM is 559 euros.

This is already a high price, but still far below than that of the competition! And for the price, you get in our opinion a very solid device, which is good in almost all areas! The OnePlus 5T will be available from 21st November.

Hardware and Connectivity

Under the hood works the Qualcomm Snapdragon 835. This is also in the non-European version of the Samsung Galaxy S8 and other top models like the HTC U11. With this CPU you experience in practice - as our experience proves - no performance losses. The performance is high, even with many tasks at the same time.

In the 3D Mark, the OnePlus achieves 40,439 points. The Antutu Benchmark rate it one of the strongest smartphones on the market with 173,013 points. OnePlus increases the clock speed of even the weaker CPUs to the performance of 1.9 GHz. It is to achieve the highest possible performance, especially in the benchmark apps. According to OnePlus, you should not overclock the cores. You want to show the users the actual performance.

The Snapdragon 835 is the first mobile processor that Qualcomm produce in a 10nm process. It offers a higher performance with energy efficiency, which extends the battery life. Depending on the version, the CPU get supported by 6 or even 8 GB of RAM.

The strong CPU itself ensures smooth operation of the mobile phone. Oneplus integrate a new app management in OxygenOS to increase the app's performance. Applications are ready to go immediately when you turn on the OnePlus 5. Programs that you rarely use, are not prioritized. So they do not have a negative impact on performance.


The case is again made of quality aluminum. Compared to its predecessor, it is two millimeters longer and one millimeter wider. The screen has grown 0.5 inches to 6 inches. Despite the large display, the OnePlus 5T feels good in the hand.

On the bottom, there is the speaker, the USB-C port, and the 3.5-millimeter jack. On the back is now under the camera and the flash, the fingerprint sensor. For this, there was no more space on the front because of the large display.

The fingerprint sensor now controls gestures as well. Swipe down, pull down the notification bar. And hold it with the camera app open, shoot a photo - this simplifies one-handed operation.

Display, Audio and Multimedia

The AMOLED screen on the front is as mentioned 6 inches. It is almost borderless and comes - how could it be otherwise - in 18:9 format. The resolution of 1080 x 2160 pixels is higher than the OnePlus 5. But due to the difference in size, both end up with the same pixel density of about 401 PPI. So content is pretty sharp, rich in contrast and colors are crisp.

While others long relied on large and high-resolution screens, OnePlus Full-HD remained true. And so does the OnePlus 5. The 5.5-inch display continues to display its contents with 1080p. In normal use, you will hardly notice a difference. But higher resolutions are important in times of VR. The display covers the DCI-P3 color space like that of the iPhone 7.

In the options, you can set a reading mode and assign it to certain apps, which will activate when you start them. The color temperature change for better readability. So that it seems like you are reading texts on paper. Because the display shows read-only content almost colorless. It is very warm, reading is actually more relaxed for your eyes. You can also activate the mode manually.

Granted, the OnePlus 5 looks a bit like an iPhone 7 Plus - especially the back side is very similar. The antenna strips are also installed in the same place. After all, it is as good and processed quality. At 7.25 millimeters, the OnePlus 5 is the thinnest OnePlus flagship to date. Thanks to its design, feels very good in the hand. Where the smooth metal is quite slippery - so always hold on tight! The case is not waterproof.

The other equipment corresponds to the OnePlus 5 and other current high-end devices. The Snapdragon 835 from Qualcomm with 8 cores and a clock of up to 2.45 GHz ensures high performance. Depending on the storage variant of 64 or 128 GB, there are 6 or 8 GB of RAM. The battery capacity of 3300 mAh does not change compared to its predecessor. The runtime should be the same despite the larger display. But thanks to software optimization - we are curious if OnePlus can keep that up.

The operating system is Android 7.1.1 with its own OxygenOS used. The OnePlus 5T also supports Bluetooth 5.0, NFC and LTE Cat12, allowing up to 600 Mbps download. And in determining the position Galileo has now got added to GPS, Glonass and BeiDou.

The OnePlus 5T has a dual-SIM slot - so you can use up to two SIM cards. A memory extension does not exist.


The next major difference is in the dual-cam on the back. The 16-megapixel main camera remains identical with an f/1.7 aperture. OnePlus exchanges the second camera. Instead of a telephoto lens OnePlus uses the second camera. It now also has a f/1.7 aperture, for better photos at low light.

In low light - less than 10 lux - the 5T, according to OnePlus, changes from the main camera to the second camera. It should combine 4 pixels to create a higher brightness with reduced image noise. We hardly notice a difference in low light between the main camera and the secondary camera. Because with both of them, we shoot low light and sharp photos that do not cause much noise. For a conclusion, we are still waiting for the detailed test.

OnePlus knows that the camera is one of the most important smartphone features. On May 18, OnePlus officially announced its cooperation with DxO. It is best known for its DxOMark photo benchmark. Based on the experience of the DxO experts, OnePlus is sure to take the clearest photos with the OnePlus 5.

On the back of the OnePlus 5 is now a dual camera with 16 and 20 megapixels. Thanks to the combination of the main camera and a telephoto lens, you can take clear photos while zooming. At least with 2x optical magnification. With 8x zoom, the picture quality is still good when there is enough light. It decreases in poorer lighting conditions. The second camera gives you a nice bokeh effect with the background blurred.

In some cases, image noise occurs, which increases despite HDR and a large image sensor in low light. We see a strong blue cast, which tends to occur more in indoor shots and less visible in daylight.

The front camera offers a resolution of 16 megapixels and a high image quality. Here the blue cast is not there.


The OnePlus 5 comes with a 3300 mAh battery. It supports Dash Charge for fast charging. In the battery, the phone reaches a running time of almost 11.5 hours. It thus proves almost as high endurance as the Galaxy S8. In everyday life, the OnePlus 5 has to be re-connected to the power outlet the next day during normal use. Thanks to Dash Charge, the mobile phone is then ready for use fast.

The fingerprint scanner is again on the front below the screen and coated with ceramic.

System and Software

As the operating system, OnePlus relies on its own oxygen system with Android 7.1 as the basis. The system comes with a UFS2.1 dual lane memory, which is 64 and 128 GB depending on the model. The memory can not get expanded via micro SD card.

OxygenOS is on Stock-Android and manages without unnecessary frills. OxygenOS offers advanced features and settings. For example, you can change the layout of the buttons or show a virtual navigation bar. You can also customize the appearance of the status bar.

With gestures, you can start defined functions or apps like the camera from the lock screen. For example by drawing an "O" on the display with your finger. With a 3-finger swipe gesture, you can take a screenshot. You can now extend the screenshot down like the Galaxy S8. You can take even a screenshot of entire web pages and not apart.

For the OnePlus 5, the second software update is already available after launch. The new OxygenOS version 4.5.3 fixes several bugs and improves system stability. With the update, crashes of the WLAN connection and the screenshot function disappear. The automatic brightness also improves and the consumption display of the data volume. Further improvements are in the stability and effects of the camera app.

On Reddit, OnePlus says it will continue to work on stabilization of 4K video recordings. So far, video stabilization only applies to videos with 1080p.

OxygenOS 5.4.3 comes via OTA update on your OnePlus 5 - usually, you will receive a notification on the phone. If this is not the case, you can start the update search in the settings.

OnePlus 5 instead of OnePlus 4

Because above all the number 4 in China is an unlucky number. It was already speculated that the new model carries the name OnePlus 5 as the successor to the 3T. The Group, which owns OnePlus, also owns the Vivo brand, which also migrated from the Vivo V3 to the Vivo V5. And indeed OnePlus skips the model name "4" in the new flagship killer.

The OnePlus One was unbeatable with the price/performance ratio. It was an absolute buy recommendation compared to former flagships. With 300 euros it would be almost a takeaway product. Depending on the memory version, the OnePlus now costs 499 and 559 euros! So the price keeps going up towards other flagships instead of the other way around!

Compared to an S8 or an iPhone 7 are also missing features. There is no waterproof case, pressure-sensitive display, memory expansion or an iris scanner. Of course, you can argue now if you need that. But OnePlus 5 is not a true flagship killer. It is a solid smartphone with customizable software for a reasonable price. Especially if you need a lot of storage space.
