Open box
As usual, OPPO is still very well equipped for the user on the accessories in the box. When opening the OPPO R11 box, we found that the phone itself had a 20W VOOC quick charger, a microUSB cable, a nice boxset, a silicon case, and OPPO also attached to the OPPO R11 display. OPPO is always so, very thoughtful to users when you buy the machine can be assured to use immediately because of the screen stickers and case, instead of having to buy accessories like many other phones.
Design
OPPO R11 is made from metal with excellent finish. The most impressive feature for us is the exceptionally thin, only 6.8mm. Thanks to this thinness and soft curved lines, the OPPO R11 fits comfortably. At the same time, the metal casing also brings a high-class feel, cool in your hand is a monolithic aluminum machine.
The biggest change in design is the two strips of the antenna that offer two very fine and delicate peaks. This is also a trend that many manufacturers use in recent times. The dual camera cluster is made very nice and compact, although it is unavoidable to bulge slightly.
In general, OPPO R11 is a beautiful and high quality metal machine. However, it is difficult to understand that OPPO still uses the microUSB connector in the context of other manufacturers are gradually moving to USB Type-C more advanced. It seems that OPPO has not yet found a solution for compatibility between USB Type-C and their exclusive VOOC fast charging technology.
Screen
The OPPO R11 has this 5.5-inch AMOLED screen and it runs at 1080p Full HD resolution, kind of straightforward. The OPPO also manages to keep the bezel around the display pretty thin, and honestly that looks like a nice little compliment. The display quality on the OPPO R11 is really strong too because the AMOLED advantage is mostly its vivid , vibrant color output, it feels lively almost instantly.
Display
The OPPO R11 comes with a 5.5-inch AMOLED panel, set at 1920 x 1080 pixels, so it lands around 401 PPI. AMOLED tech is usually praised for vivid hues, really dark blacks, and solid contrast ratios, and the R11 screen doesn’t really fall flat there.
On the OPPO R11, the colors look punchy, and they seem to work nicely for all kinds of media, like watching videos or even gaming. Those deep blacks give you a more immersive kind of mood, especially when you’re viewing movies, or using apps that lean on darker themes. There’s also a broad color range, so the whole visual ride feels a bit more enhanced, overall.
With Full HD resolution, text and pictures look crisp and clean. Sure, it may not hit the same pixel density as some higher-end phones that use Quad HD, but for most users the R11 screen is honestly more than enough. Brightness is also fairly commendable, so it stays workable even when you’re outside in brighter conditions.
From different viewing angles, the OPPO R11 performs well. Color shift is minimal, and brightness loss doesn’t become too obvious, even when you tilt the phone. That makes it handy for sharing content too, and for using the device across varying lighting setups.
For display options, the OPPO R11 includes a “Night Shield” mode that cuts down blue light emission, to help reduce eye strain during night time use. You can also tweak the color temperature, and pick either cooler or warmer tones to match your preference.
Software
OPPO R11 comes with the latest Android 7.1.1 operating system, of course still under the custom ColorOS 3.1 interface. This is a very customized ROM, different from the original Google interface. With the interface design and features quite similar to iOS, you will be easier to use than other Android machines. At the same time this interface is also very nice, friendly and easy to see.

Performance
OPPO R11 is, somehow, the first smartphone in the world to come with the Snapdragon 660 processor, a brand new chip from Qualcomm . The Snapdragon 660 packs 8 customizable Kryo 260 cores, 4 core 2.2GHz and 4 core 1.8GHz, which is kind of the point. OPPO says this CPU will bring 20% more CPU power and as much as 30% more GPU than the OPPO F3 Plus Snapdragon 653 . That older model has been rated highly for performance, so the upgrade actually matters.
Besides the Snapdragon 660, the OPPO R11 also includes 4GB RAM and 64GB of internal storage. In practice this ends up being a rather capable set up for the price category. Sure it is not on the same level as Snapdragon 835, but the ANTUTU score over 118,000 is still enough to breeze through essentially any game or daily application.
Camera
OPPO R11 owns the camera with extremely terrific hardware parameters. The main camera consists of two cameras, a 16MP Sony IMX398 aperture f / 1.7 and a 20MP Sony IMX376 f / 2.6 Tele. This dual camera unit can take 2x optical zoom. The front camera is a 20MP single-megapixel camera, which can also be used to capture deleted images.
Battery Life
The OPPO R11 comes with a 3,000mAh, non-removable battery, nothing too wild but pretty standard for a phone in this class. In day to day situations , with moderate use, it can usually get you through the whole day on a single charge. Stuff like browsing the web, scrolling social media, streaming videos, and yes making phone calls, all that kind of normal routine works out fine.
But once you switch to heavier workloads, like gaming sessions, or lots of camera time, battery life tends to drop off faster. Still the OPPO R11 holds up decently, it doesn’t feel like it’s falling apart. The 3,000mAh capacity together with the Snapdragon 660’s power efficiency creates a decent compromise between speed and stamina. Most people should see roughly 4 to 5 hours of screen-on time on average, which is pretty much what you’d expect from a mid-range smartphone.
Another thing worth mentioning is OPPO’s own VOOC Flash Charge support. The idea with VOOC Flash Charge is that it can refill the battery quickly while avoiding major overheating, which is always a good sign. In real use, it can bring the OPPO R11 from 0% up to around 75% in about 30 minutes. That “quick top-up” style is useful when you’re out and you need a little extra boost during the day. Do note though, this rapid charging is only available when you use the included VOOC charger and cable , not random adapters.
Finally, wireless charging is missing on the OPPO R11. Over the last few years, that feature has become more and more common, so if you care a lot about charging without cables, this is something to seriously keep in mind. For many users it may not be a deal breaker, but it depends on your habits.
Audio and Connectivity
On the whole, the OPPO R11 gives you a pretty decent audio experience, but it’s not really the device’s most standout feature. There’s a single bottom firing speaker, and it manages to sound clear and fairly loud, still though , when you use the phone in landscape mode and your hand covers the speaker area, the sound gets kind of muffled, like happens with a lot of phones that only have one speaker. For everyday listening it’s fine, but it doesn’t bring the deeper, more textured feel you might notice on models with dual speakers or built in audio enhancements.
If you like wired headphones, the OPPO R11 is at least considerate, because it keeps the 3.5mm headphone jack. That’s a nice touch in a time when many brands decided to quietly let go of that classic port. On the wireless side, the phone supports Bluetooth 4.2 so you can pair up wireless headphones, plus other Bluetooth enabled gadgets without much hassle.
Connectivity wise, the OPPO R11 handles the essentials properly. You get dual SIM support alongside 4G LTE , so mobile data speeds should stay in a decent place, not sure why it matters but you know. It also brings Wi‑Fi 802.11 a/b/g/n/ac, which helps keep connections stable on both the 2.4GHz and 5GHz bands, kind of handy for a household network or those crowded public areas. For navigation you have GPS, GLONASS and BDS included, so location tracking feels more reliable , which in turn makes the R11 a dependable choice for map apps.
Still, there is one place where the OPPO R11 doesn’t quite keep up, and that’s the charging and data transfer side, since it uses a microUSB port. By 2017, plenty of smartphones, even some mid range ones, had already started moving toward USB Type-C. Type-C tends to offer quicker data transfer, and you don’t have to worry about orientation when plugging it in. Sticking with microUSB feels a bit old fashioned, especially because the rest of the device seems modern enough and generally well rounded.
Conclusion
The OPPO R11 is, in general a well-balanced smartphone, you know it kinda hits that sweet spot between performance, design and camera features. The sleek metal unibody build feels pretty premium, and the AMOLED screen shows vivid colors plus those deep blacks, so the whole viewing thing looks nicer than expected. With the Snapdragon 660 processor paired with 4GB RAM, everyday use stays smooth for most apps and such, and then the dual-camera arrangement gives you more photography ways to try out.
And yeah, the camera is probably the main thing here. It really does well in regular shots, also portrait mode looks solid. The front camera matches up with OPPO’s “Selfie Expert” idea, giving sharper selfies and letting you play with multiple beautify settings, which is what many people actually care about.
Software wise, ColorOS brings several customization options and a bunch of handy features, but it might not be everyone’s cup of tea. The background app management can feel a little too strict, and the overall interface has this iOS-like vibe, which some users like, and others don’t. Battery performance is pretty decent too, and VOOC Flash Charge is a major plus if you keep forgetting to plug the phone in, or you just need fast power.
Still, it’s not perfect, no. Using a microUSB port instead of USB Type-C is a clear letdown for modern standards, and the fact that there’s no wireless charging might disappoint certain buyers. Also, ColorOS can feel kinda heavily skinned, and plus the bloatware situation might make some people bounce off, who actually want a cleaner , more streamlined system.
So overall the OPPO R11 sits as a solid mid range rival, especially if camera quality and design matter the most to you. It’s a convincing bundle, like it probably covers what most people want, and that makes it a good choice if you’re after something capable , stylish, and not too complicated.
