Beautiful Phone, Beautiful Performance


Although slated for release in only a handful of countries, around the world, the Oppo R11s is a very ambitious piece. This device generally packs enough bells and whistles to be a great mid-range device, from cameras to CPU, features to display. 

Coming in such a classy red, can this eye-catching device captivate anyone on how it performs ?

The R11s looks rather impressive, having a metallic unibody that’s relative to the OnePlus 5 design language. This is a slim device with a very tall looking screen thanks to its 18:9 aspect ratio, which is the trendy direction many manufacturers are making with their displays. 

The device like this gives off  minimalist vibes, mixed in with an alluring red-color scheme. Bezels are really thin, with no features on the device that we could deem distracting. It’s clean and clear cut, just the way we like it. The front of the device is free of capacitive buttons, with only the front-facing camera and motion sensors located just above the screen. 

Adding design, the R11s exudes character from Starry Sky, a unique finish on the top and bottom of the device, featuring shades of its main color flowing out into inside the glass case of the screen. It resulted in a stylish finish that made the device look slimmer and accented. 


The display on the R11s is an improvement over the R11’s Full HD AMOLED display, bumping it up to an 18:9 FHD+ AMOLED display with a resolution of 2160 x 1080, boasting a 401ppi. Protecting the screen is a Corning Gorilla Glass 5, along with a factory-installed screen protector. 

In terms of the 18:9 ratio, playing certain content like videos and some games on the device would result in the same black bars we see when we play standard 16:9 content. It’s not really a big issue, as forcing the device to play 16:9 content on an 18:9 ratio would only result in stretching and making the video look disproportionate. 

Color reproduction is rich, along with deep blacks and strong contrast, thanks to its Samsung-made panel. A missing feature on the R11s would be color profile picking. With only its default profile, users may feel a tad bit restricted by not being able to pick out their preferred profile, whether they intend to take full advantage of an AMOLED’s strengths. As for brightness, the R11s generally isn’t very bright, which is great for indoor usage and some scenarios of darkness such as being in your room with all the lights off. This just basically means that the R11s may not be too dependable under direct sunlight due to not being bright enough. 


Out of the box, the Oppo R11s run on ColorOS 3.2, skinned over Android 7.1.7 Nougat, which brings users interesting new features such as AI Learning and facial recognition as an unlocking method. 

ColorOS 3.2 still runs the same ship as any other Oppo device. There’s no app drawer still, so iOS and some other Android brand users would feel right at home. 

For gesturing, it’s not difficult to navigate to anything on the R11s (or anything with ColorOS for the matter). Swiping down from the top would fetch you the notification shade, showing all your messaging or app notifications that you may have missed. Swiping up from the bottom brings you the Control Center, just like iOS. This is where all your toggles such as Wi-Fi, Bluetooth and Mobile Data are located. 

Just like the Oppo  F5, Game Acceleration is on board too, and can be accessed from the settings. Of course, when it comes to gaming on the R11s it definitely performed well thanks to its new choice of hardware. As for other features, users will still get to enjoy the now-standard Clone Apps and Split screen features. Clone App basically allows users to install two of the same app and use them during the same instance, such as having two WhatsApp accounts for two numbers, and two Facebook Apps for managing two accounts. Split-screen just splits the screen for users to multitask on another app in real time. The app must be able to support that feature in order to be used during split screen mode.  


This is where it got real interesting. The Oppo R11s packs a Snapdragon 660 processor, the immediate successor of the Snapdragon 653. This line of Snapdragon processors (especially the 660), although designated as a mid-range chipset, packs both processing and graphical prowess comparable to even the flagship Snapdragon 835

Featuring custom kryo 260 cores, it’s a unique surprise to see a device pack such a type of core, as compared to the more common ARM Cortex-A72 and A53 cores that feature a big.LITTLE architecture. 

Apart from the processor, the R11s carries 4 GB of RAM and 64 GB of internal storage. This combo is slowly getting old, but not unreliable. You can still bump memory up to 265 GB via microSD expansion. 

As for gaming, the R11s performed admirably. Games were constantly at 60 FPS (if available), with all settings dialed up to high. Games like Riptide, Need For Speed No Limits and Arena of Valor performed very well on this device. This kind of real time performance is commendable and expected, thanks to the Snapdragon 660’s 14nm process, which is known to be very energy efficient. This probably was what kept the device consistently cool even during 3D acceleration during gaming. 


The R11s comes with a dual-camera setup and a strong selfie camera in the front. The primary rear lens is 16-megapixels, with the secondary telephoto lens being 20-megapixels. Both possess the same f/1.7 aperture.

We rather enjoyed the novelty 1x to 2x tapping zoom on the camera software, alongside the quality that these lenses could deliver. In terms of image quality, the R11s is an improvement over the R11, in terms of color reproduction, contrasts and speed. The only downside of this is the lack of any form of image stabilization, which affects the overall quality of your shots, since it would take a longer time for the shutter to capture the image when it gets dark.  

As for video, the R11s is capable of capturing video on several levels of quality:  

  • 720p : 60fps
  • 1080p: 30fps
  • 4K: 30fps

On 1080p, videos are decent in terms of detail and color. Dynamic range and contrast were impressive if not rather good. As for 4K, videos had notable levels of detail and excellent contrast. Colors were punchy and there were not signs of frame drops during moments of sudden motion. Stereo recording on any level was sub-par, with some voices being soft despite being at are decent distance when speaking.

Selfies on the R11s were a treat. In fact, its 20-megapixel selfie cam outdid its rear counterpart. I could even dare say that it was one of the most impressive front-cameras I have ever used. Almost every aspect of quality was great, from colors to contrast, focus and resolution. 

Battery Life

Powered by a 3,200mAh Li-Po battery, the R11s boasts a hardy battery life of slightly over 2 days on a single charge. Of course, this varies according to each user’s usage pattern. Oppo devices are one of the few brands out there that proves that it’s okay to forget about charging your phone sometimes. A super fast VOOC charging brick with matching microUSB cable takes care of all your charging needs, delivering a staggering charging speed of 0%-60% in 25 minutes.

A full charge cycle takes around 85 minutes, and that’s alright, considering that the charger dispenses a maximum of 20W @ 4A of charge into the device. 


Overall, the R11s fares very well as a mid-range device with updated features that are up to speed in the market today. Several features on this device makes it quite an irresistible option for many, such as a great design, a beautiful 18:9 AMOLED display, high performing cameras and very reliable performance. 

Its Snapdragon 660 processor is definitely a step forward, alongside the never-disappointing vooc charging capability that Oppo fans adore very much. Some steps backwards could be the lack of NFC and some form of image stabilization , but it’s definitely forgivable if you are getting this device as an entertainment and picture-taking solution. For an asking price of SGD $699, it’s arguable that there are many other choices out there, but only a small handful could impress based on looks and features the way the R11s has.
