The Oppo R11 features a 5.5" AMOLED screen with 1080p resolution. It's not the Optic AMOLED in charge of the OnePlus 5, at least not on paper, but it's still an AMOLED and the expectations are high as usual.
A peek under a microscope revealed a familiar Diamond Pixel arrangement. It's the same pattern we saw in the OnePlus 5 and the Galaxy S8 series.
The AMOLED on the Oppo R11 is capable of 410 nits of maximum brightness - a fine score for this type of screen, and just a few nits short of the OnePlus 5's achievement.
The contrast is excellent, as expected.

The color accuracy on the Oppo R11 is far from spectacular with an average deviation (DeltaE) of 6.1 and a maximum of 12.4 in the whites. Oppo chose to tone up the main RGB colors and they ended up oversaturated. Not sure if the extra punch will be universally liked, but it shouldn't be that much of an issue.
Sunlight legibility is better than before, a massive improvement over the R9 and R9s, and only a slim one over the OnePlus 3T and 5. The Gorilla Glass 5 laminated AMOLED display keeps reflections well in check. Note that even with the pre-applied screen protector, which we removed for the test, the R11 still scored an impressive 4.131 in sunlight contrast.

Battery life
The Oppo R11 is powered by a 3,000mAh battery (Li-Po) sealed inside its metal body. The phone supports the fast VOOC charging standard and is bundled with the proper charger for it, a 5V unit at 4A for a total output of 20W. In our tests, it reached a 65% charge (from flat) in half an hour, and full charge in an hour and a half.
ColorOS features a few power saving modes that are enabled by default, so you may notice how the phone often intervenes by killing background apps for you. If that causes issues, you can exempt specific apps from this behavior. We found it too aggressive to our taste and had to disable it for a few apps (a minor note: we wish we had a way to do this from the app switcher, instead of having to go into the settings).
We ran our battery tests and the 3,000mAh battery posted an overall score of 81 hours, matching the Oppo R9s and the R9 (also known as F1 Plus). The R11 did great on talk time, web browsing, and video playback test, while its standby consumption is just about average.
The Snapdragon 660 didn't outclass the Snapdragon 625 in the R9s or the Helio P10 inside the R9, but it didn't lag behind either.
Our endurance rating denotes how long a single battery charge will last you if you use the Oppo R11 for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern so our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.
Connectivity
The Oppo R11 is a dual-SIM phone powered by a Qualcomm chipset, which means excellent support for a wide range of mobile wireless connectivity. This includes ten LTE, four GSM, CDMA, and five 3G bands. VoLTE is supported as well for improved audio quality.
The R11 supports Wi-Fi 802.11 b/g/n over 2.4GHz and 802.11 a/n/ac on 5GHz (dual-band Wi-Fi). Wi-Fi Direct, Bluetooth 4.2, A-GPS, and GLONASS are also enabled. There is no NFC support, though. The R11 does not have an FM radio or an IR blaster.
The microUSB 2.0 port on the phone offers On-The-Go for connecting accessories.
