Reviewing OnePlus X - Is it the budget flagship killer?


Two years ago, the OnePlus company launched its first smartphone called OnePlus One, promoted as the "Original flagship killer". The One model was designed to compete in terms of performance, quality and PRICE, with the flagship devices released by the well-known companies in the Android market. In the summer of 2015, the manufacturer launched the successor to the OnePlus One, the new "flagship killer", OnePlus Two. Late in the same year, the C hinese company released a new smartphone called OnePlus X. This smartphone was designed as a budget alternative for those who don't want to pay 350 dollars for the OnePlus Two. Over the last month we have had the chance to test and play with the OnePlus X, and now it's time for us to share with you everything we found about it, in this review:

Hardware specifications and packaging

The OnePlus X comes in a white and red premium-looking box. On the top side you'll see the OnePlus logo and a big X, while on the bottom you'll find two IMEI codes (the smartphone is dual sim) and some information about the package and the device.

Underneath the OnePlus X, you'll find the power charger, the USB cable, the protective silicone case, the SIM tray ejector, the quick start guide and the user guide. You won't find any headphones though and you will have to purchase them separately.

The OnePlus X comes in three variants: Onyx, Champagne and Ceramic. The Onyx and Ceramic versions are black and the Champagne variant is white. What is very important to mention is that the Ceramic version is limited, and it is 100 $/€ more expensive than the other two variants.

OnePlus X is powered by a quad-core Qualcomm Snapdragon 801 processor at 2.3 GHz, 3GB of memory RAM and an Adreno 330 graphics processor. In terms of storage, the smartphone comes with 16GB of internal storage space that can be extended with a microSD card up to 128GB. The smartphone has dual-sim technology, but if you choose to add a microSD card you will lose the second SIM slot.

The screen uses a 5 inches AMOLED capacitive touchscreen with 16M colors panel with a resolution of 1920x1080 pixels and a pixel density of approximately 441 dots per inch. The display has wide viewing angles, high contrast, very good color reproduction and it is protected by Corning Gorilla Glass 3. By default, the display is covered by a quality anti scratch screen protector slot.

In terms of size, the OnePlus X measures 140 mm (5.51 inches) in height, 69 mm (2.72 inches) in length and only 6.9 mm (0.27 inches) in width. It weighs only 138 grams (4.86 ounces) for Onyx and Champagne versions and 160 grams (5.64 ounces) for Ceramic. As you can see it is an average-sized smartphone that is easy to carry around but if you have small hands it is a little hard to handle with only one hand.

The OnePlus X has a 13 megapixels rear camera, with an F2.2 aperture, autofocus, LED flash, HDR and panorama capabilities. The front camera has 8 megapixels with an F2.4 aperture that comes very handy in a low-light situation. Both rear and front cameras are capable of recording video at 1080p at 30 frames per second and 720p at 120 frames per second.

In terms of connectivity, the device comes with Bluetooth 4.0, USB 2.0, all standards of the 2.4 GHz Wi-Fi technology, Radio FM and GPS. OnePlus X has a 2525 mAh battery that should keep the smartphone alive more than 12 hours in conditions of normal use. It works with two nano-SIMs that can be connected at the same time through 4G but you cannot use both SIMs at the same time for the Internet connection.

The OnePlus X has the specifications of a high-end smartphone from the end of the year 2014. Today, we can say that the OnePlus X is somewhere between the midrange and high-end branches of Android smartphones.

Design and build quality

When you touch the OnePlus X for the first time, it feels like premium quality. The smartphone has a unibody design and it is built of glass and aluminum (the Onyx and Champagne editions) or ceramic and aluminum, if we talk about the Ceramic version. In the picture below, you can see the Onyx version that we tested.

On the front side, above the display, you will find the earpiece, the front camera, the ambient light sensor and the proximity sensor. In right-upper corner you will find the multi colored LED notification light. Below the display, if you look carefully, you will see the capacitive Android buttons.

On the back are the rear camera, the LED flash and the OnePlus logo.

On the right side you will find the Power button and the volume rockers, on the upper rim there are the 3.5mm audio jack and the second microphone used by the noise cancellation technology. On the bottom you will find the speaker, the main microphone and the USB connector.

On the left side, you will see something that is very rarely found on a smartphone: the Alert Slider. We will say more about this feature in the next section of this article.

Even if you pay a mid-range price for the OnePlus X, you get a smartphone with a high level design, built from the highest quality materials.

The smartphone experience on the OnePlus X

The phone experience with OnePlus X is exactly as we expected from this hardware configuration. We used this smartphone with two 4G SIM cards. During phone calls, the sound is loud and clear, and the active noise cancelling technology works works very well even if you are in a noisy environment. The second SIM card slot doubles as a microSD tray, which means that you will have to choose between expanding your storage or using a second mobile service provider.

Even though the package doesn't include any headphones, we tested the audio quality with some aftermarket ones. When listening to music or watching videos, the audio quality is quite good.

As we said earlier, OnePlus X provides a Full HD display with AMOLED technology. It has vivid colors, high contrast and thanks to the AMOLED technology the black color is very deep. The touchscreen works very well even though you choose to keep the default screen protector.

We already mentioned that OnePlus X comes with something that you will find on very few smartphones:the Alert Slider. This is a switch that allows you to put the device in one of three notification available modes: All notifications , Priority interruptions only and No interruptions. If you put the smartphone in the All notifications mode, you will receive notifications from all applications installed on your smartphone and, of course, if you enable No interruptions , you won't receive any notification, but the alarm will still ring. If you choose the Priority interruptions only mode, you will be notified only by specific applications.

The only downside is that you can't select which apps can send notifications and which can' t , but you can choose to be (or not to be) alerted by events and reminders, calls or messages.

All in all, the Alert Slider turns out to be very useful when you are in meetings and you need to put the smartphone on silent very quickly.

OnePlus X comes with a 2000mAh adapter that fills the battery by approximately one percent per minute, which means that the battery will be fully charged in about one hour and a half. We also noticed that while charging the smartphone is overheating a little.

In a one month of daily use we had with it, the OnePlus X worked well, without any major problems. It offered a great smartphone experience and it had no problems running all the applications and games we have installed. The signal reception is good in all types of networks (2G, 3G and 4G), and during phone calls the sound is loud and clear.
