OnePlus X Review

Skye Hudson 08-12-2015

How do you make a single phone that pleases everyone? OnePlus seems to think that you can’t. A few months after announcing their OnePlus Two “flagship killer” YouTube Drops Google+, The OnePlus 2 Flagship Killer... [Tech News Digest] The unimportance of Google+, the OnePlus 2 arrives, eBay Now is no more, Steve Jobs is The Man In the Machine, and everything wrong with Super Mario Bros. Read More , OnePlus released the OnePlus X, a smaller, cheaper device with some pretty major differences from the Two.


So the X is kind of a like a sequel to the OnePlus One (which we loved Top Six Best Features Of The OnePlus One -- And One Drawback I've been living with the OnePlus One for a few weeks now, and it's amazing, but it's not perfect. Let's run through some of the best features -- and one downside. Read More , even compared to other great phones The Best Unlocked, Off-Contract Smartphones Available Buying unlocked phones can save you lots of money, but with so many options out there, which unlocked phone is the best? Read More ), but taken in another direction. Whereas the Two will satisfy the tech-obsessed phablet-lovers out there, the X is for the average consumer who isn’t obsessed with specs but still wants a solid, affordable device.

And honestly, I’m impressed. Let’s take a look at everything this smartphone has to offer.


  • Price: $250 (Invite currently needed to purchase)
  • Dimensions: 140mm x 69mm x 6.9mm (5.5in x 2.7in x 0.27in)
  • Weight: 138g (4.86oz)
  • Screen: 5″ 1080p AMOLED Gorilla Glass
  • Processor: 2.3Ghz Quad-core Snapdragon 801 with Adreno 330 GPU
  • RAM: 3GB
  • Storage: 16GB
  • MicroSD Card: Yes, up to 128GB
  • Operating System: OxygenOS (based on Android 5.1.1 Lollipop)
  • Battery: Non-removable 2,525 mAh Lithium-ion Polymer
  • Cameras: 13MP rear-facing with f/2.2, and 8MP front-facing with f/2.4
  • Extras: Alert slider, LED notification light, Dual Nano-SIM slots, FM Radio, included rubber phone case
  • Color: Onyx



OnePlus talks a big game about their craftsmanship, but I’d be lying if I said they were all hype. This really is a gorgeous phone. Straight out of the box, it just looks like a professional, high-end device. You might expect that if you were buying a $700 iPhone or Samsung device, but this is a $250 phone from a relatively unknown Chinese manufacturer.

Usually for that price, you get squeaky plastic and weak MediaTek processors — but not with the OnePlus X. You’re really getting a premium device at a budget price, especially in the hardware department.


Though some of this polish is surely due to the fact that it looks a bit like the iPhone 4 and 5. It has the size and the brushed aluminum sides of the iPhone 5 with the backplate made of glass like the iPhone 4, and the camera in the top corner isn’t helping any comparisons.

Still, if you can look past the similarity to the older iPhones, it’s a very nice Android handset.

The power button, volume rocker, and SIM card/microSD card slot are all on the right side of the device.



Also, take note that even though this is a dual-SIM device, you can’t use two SIM cards if you plan on using a microSD card to expand your storage, because the microSD card goes in the second SIM card slot.

On the top of the phone, you’ll find a headphone jack as usual. The left side is home to a new “alert slider”, which may seem foreign to Android users but might seem familiar to, well, iPhone users.


The biggest difference is that this alert slider has three levels rather than the iPhone’s two. They correspond to Android Lollipop Android 5.0 Lollipop: What It Is And When You'll Get It Android 5.0 Lollipop is here, but only on Nexus devices. What exactly is new about this operating system, and when can you expect it to arrive on your device? Read More ‘s new notifications controls How to Set Up Android's Priority Mode (and Get Back Silent Mode) Volume controls changed a lot in Lollipop, so we're here to help you make sense of all of it. Read More : All notifications, Priority only, or No notifications. With the alert slider set, you can’t leave any of those three levels without physically moving it — so accidental volume button presses won’t unmute your device.


For me, this is pretty useless since I leave my phone constantly on the no notifications option, but if you switch between them a lot, I could see it being an easy way to change without having to open up your phone and change settings. Though three levels makes it a tad more cumbersome than that iPhone’s simple switch.

Along the bottom, you’ll find a regular microUSB port (not the new Type-C What Is USB Type-C? Ah, the USB plug. It is as ubiquitous now as it is notorious for never being able to be plugged in right the first time. Read More that you’d find in the OnePlus Two) and dual speakers — but more on those later.

There are hardware capacitive keys — Back, Home, and Recents — but you can disable those and use the on-screen software keys if you prefer.




This screen is gorgeous. I know a lot of reviewers say that about a lot of phones, but this screen has really blown me away. It’s bright and visible in direct sunlight, the colors absolutely pop off the screen thanks to the AMOLED display, and cramming a 1080p display onto a 5″ screen gives it a high 441PPI (a 2K screen would just be overkill How Advertisers Trick You into Buying Their Smartphones You hear something about an octa core, 20-megapixel, Quad HD smartphone with 3GB of RAM. You have no idea what that means, but it sure sounds fast and powerful in the commercial. Read More ).

In fact, just using it side-by-side with my OnePlus One really makes me want to upgrade. You can see them compared above, with the X on the right and the One on the left — both at full brightness. This may be a budget device, but the screen is not an area where they cut corners.



Placed along the bottom of the phone, your hand will likely cover the speakers if you’re holding the phone in landscape mode — but at least they’re not on the back. Sadly, they seem a bit quieter than the speakers on my OnePlus One. You might need to get crafty making your own DIY smartphone speakers Making Your Own Smartphone Speakers - MakeUseOf Tests The average smartphone speaker is an insult to an audiophile's ears. Poor quality, low volume, and a lack of bass can ruin the sound. Since those speakers are in-built, there isn't an easy way to... Read More .



Wiht a 13MP f/2.2 camera on the back and an 8MP f/2.4 camera on the front, you won’t be disappointed with the photos here (well, really, they’re 12.4MP and 7.6MP respectively). These are in a 4:3 ratio, though; if you want 16:9 photos, you’ll be reduced to 8MP on the back and 2MP on the front.


Above, you can see what the camera app itself looks like. It’s very simple and easy to get used to. You have options for Clear Image (OnePlus’s algorithm for getting high megapixel shots), HDR, and Beauty mode. Swipe in from the left, and you can use a time lapse mode or take slow motion video (though only in 720p).


You can see a sample shot I took with the rear-facing camera above on a cloudy day (cropped, of course, cause that 4:3 aspect ratio is way too tall). For this price, it’s really the best camera you’re going to get, and it’s an impressive camera for any price range.

But that’s enough little bits and pieces — let’s take a look at the software that powers this beast.

Oxygen OS


The OnePlus One launched with CyanogenMod, but relations between the two companies quickly soured, and OnePlus was forced to develop their own in-house operating system, which they dubbed Oxygen OS. It’s currently based on Android 5.1 Lollipop, and while OnePlus has said that the Two will be updated to 6.0 Marshmallow Android 6.0 Marshmallow: What It Is and When You'll Get It Android Marshmallow is here -- but why should you care? Read More in the first quarter of 2016, they haven’t said anything about the X yet — though I’m sure we can expect an update by Q1 or Q2.

Until then, though, the software here really isn’t bad. Oxygen OS keeps it simple, only changing small things. It’s not like Samsung’s heavy-handed TouchWiz skin Android Skins Explained: How Do Hardware Makers Change Stock Android? Hardware makers like to take Android and morph it into something that is entirely their own, but is this a good or a bad thing? Take a look and compare these different Android skins. Read More  — it’s more like a little polishing of stock Android.

One of the most noticeable differences comes when using the default launcher (though you could use an alternative launcher Which Android Launcher Should You Use? We Compare the Best! These awesome launchers will have your Android device feeling brand new. Read More ), because there’s an HTC Blinkfeed-like stream that lists your frequently used apps and can hold widgets.


You get two apps not available on stock Android: a file explorer called Files and an FM radio app called OnePlus Radio. If FM Radio is your thing, it works great and has a lovely, modern interface.


In the Settings, you can switch between a light and a dark interface. The dark interface, as it uses a pure black background, should help to save battery with the AMOLED screen Common Mobile Display Technologies You Should Know When you're comparing different mobile devices, whether they're phones, tablets, e-readers, or laptops, one of the differentiating features can be the display technology. But do you know the differences? Read More . With the dark interface selected, you can also change the accent color to personalize your device a bit more.


And OnePlus even gives you the option to control individual permissions for your apps under App Permissions.

For example, making an app purchase may expose personal contact information, including one’s name, physical address and email address, to... Read More .

Battery Life

I was worried when I saw that the X would have such a significantly smaller battery than the Two — only 2,525mAh? But in real world usage, it didn’t turn out to be too bad. In fact, I’d say it was on par with my OnePlus One, which I’m very happy with in the battery department.

Heavy, heavy usage could kill the phone before the end of the day, but on an average day I made it to bed with 30% battery or more left. Battery life is definitely not an issue here.


This is another area where you might expect the X to be inferior to the Two, but the Snapdragon 801 inside of it really chugs along. Plus with 3GB of RAM, I haven’t had the phone hesitate at all when switching betweens apps or playing games. Plus, it stayed relatively cool the whole time.

If you’re worried that the X is underpowered and feels like a budget device — don’t be. This is a flagship hiding under a budget price, and it can handle anything that the other top devices can.


This is the category where the X really knocks it out of the park. At only $250, you really won’t find a better deal on a smartphone — except for maybe the Moto G.

Still, I’ve played with a Moto G before, and the OnePlus X really feels a lot more premium. OxygenOS is lightly done, just as Motorola’s skin is, but the hardware is more solid. You also get much nicer cameras, more expandable storage space, and more RAM with the X.

Should You Buy It?

I’m beyond impressed with this phone. You won’t get a fingerprint sensor like the OnePlus Two, and it has slightly lower specs, but the ability to add expandable storage is a huge plus. Overall, it feels like a flagship smartphone with a super low price. How could you not love it?

The only trouble is actually buying it. OnePlus is notorious for its invite system, and the OnePlus X currently requires an invitation to purchase. Getting an invitation isn’t hard, though — simply check out their website and add your email to the waiting list.

Note that there have been reports of 4G LTE not working in the United States, so be sure to verify compatibility with your carrier before purchasing. This OnePlus X was tested in France and connected fine to 3G, HSPA+, and 4G LTE networks.

Our verdict of the OnePlus X:
If you’re looking to buy a cheap phone off-contract, and you’re willing to wait a bit to get an invite, definitely buy this phone. It has the best specs for its price range, and it’s an extremely well-built device.

    I have the OnePlus One after fighting through the invite system. After I gave up and wrote OnePlus off my friend gave me an invite so I bought it. Its going just past a year now and I still like it but I would not buy another OnePlus device after this given their invitation strategy and the other options on devices that are now available. The OnePlus One was the first and last device by this company that has NFC. I didnt see in this article where they focused on the OnePlus X not having NFC. They are also prone to screen issues. If someone is going to review then make it an honest review and not a kick-back review. Give both the PRO's and the CON's. People can search Google for issues with OnePlus so there's always that. As stated, I do like my OnePlus but there's no way I'd buy a device from the company again.

      yo this was a completely honest review, what makes you think i wasn't being honest?? i spent time with the device and these are my impressions. honestly i didn't talk about NFC because I never use NFC and it's not applicable to me, but you'll notice it's not listed in the Specs list -- folks can use their eyes. I did give the pros and the cons, but the invite system has worked well for me (clearly, I got this device with no problem and my last OPO), and I've never had an issue with the screen on my OPO or this OPX. no need to attack the honesty of my review just because you and i have different views of OnePlus. i was definitely being honest, lol.

    Two very underwhelming things that I reckon you didn't focus on enough:
    - Who knows if it will get an update to Android 6.0? That's a fairly major update (at least backend-wise) and I don't think the company doesn't have a history with those.
    - Doesn't use USB Type-C, so charging is slow like the old days. This is a huge issue for me, still an issue for others but maybe to a lesser degree. I'm very bad at remembering to charge. I know this is something of a personal issue, but still one that gadgets try and SHOULD try to resolve.

    • Riley J. Dennis
      December 11, 2015 at 12:33 pm

      yeah it's pretty sad there ain't no USB type-C, but hey at least no adapters or anything involved, just keep using all the same ol cables

      and i reckon it'll get an update to 6.0. maybe not the fastest update in the world but OnePlus wouldn't let their only devices go un-updated.
