Oppo R7s review: Filling the gaps

Filling the gaps

GSMArena team, 11 December, 2015.

5.5-inch AMOLED display

The entire R7 lineup makes use of AMOLED displays and the R7s is no different. The screen is 5.5 inches in diagonal and the resolution is 1,080 x 1,920 pixels, which makes for a density of 401ppi.

Our microscope photo revealed a customary Diamond PenTile matrix. The green pixels are twice as many as any of the other two colors but they are smaller in overall size.

Oppo R7s review

The Oppo R7s maximum brightness level is good for an AMOLED unit (365nits) but in terms of color accuracy, there is a lot left to be desired. With an Avg DeltaE of 8.2, it's certainly not the worst phone screen in this respect, but just so we're clear, if color accuracy is important to you, that's not the right phone to deliver it. There are also no options for adjusting the screen colors or white balance.

Of course, outside color critical applications, color accuracy is a largely subjective topic so we bet you wouldn't notice anything wrong with the screen's color rendition without a proper calibration reference.

The R7s aced our sunlight legibility test. It scores substantially higher than both the R7 and R7 Plus, but also outshines the Galaxy A7. And while the OnePlus 2 scores decently for an LCD, the LG G3 posts rather miserable numbers here.

Connectivity

The Oppo R7s carries the same set of connectivity options as its brethren. It's a dual-SIM dual-standby device with both cards supporting quad-band 2G, while SIM1 also supports quad-band 3G and a selection of LTE bands, which vary by region. The distinction between SIM1 and SIM2 is made in settings so it doesn't matter in which slot you put your primary card.

The smartphone has Wi-Fi 802.11 a/b/g/n/ac both in the 2.4GHz and 5GHz spectrums, and also Wi-Fi direct and hotspot support. There is a GPS receiver, Bluetooth is the 4.0 iteration, but there's no NFC, nor is there an FM radio.

The microUSB 2.0 port supports USB on-the-go to let you attach peripherals, though it's off by default and the option to enable it is buried deep in the settings. You also need to enable it before you actually attempt to connect the USB peripheral.

A standard 3.5mm jack completes the wired connectivity package.

Oppo R7s battery life

The Oppo R7s packs a 3,070mAh battery, which like its display diagonal, puts it in between the R7 (2,320mAh) and R7 Plus (4,100mAh).

It would seem that for its 5.5-inch screen size, the R7s is more than adequately powered, the Huawei Mate S has a smaller 2,700mAh battery, the Xperia C4 and Galaxy A7 pack 2,600mAh worth of juice, while the LG G3 has a 3,000mAh powerpack. That said, next year's Galaxy A7 has an even larger 3,300mAh battery.

However, our R7s battery life test left us with mixed feelings. Much like the R7 and R7 Plus before it, the R7s excelled at 3G call endurance with just over 24 hours before it called it a day. In video playback the R7s was good for 14 straight hours before it ran out of power - another great score.

Not so in web browsing, however, where the R7s could only last for about 8 hours, regardless of whether you're using Oppo's custom browser or Google Chrome. This was also the case with the other R7's we tested - excellent call and video endurance and only average numbers in web browsing. It's either that the AMOLED screen is not that efficient in displaying our predominantly lightly colored test web pages or Oppo needs to put in a little more effort in optimizing battery life for this use case.

Oppo R7s

The Mate S showed a more balanced performance, with a little short of 10 hours on the web and 11 and a half hours in video playback, but a rather low 14 hours of 3G calls. The Galaxy A7 does 9 and a half hours on the web and 10 hours in our video test, and it also outlasts the R7s by an hour of voice calls.

Make note that our proprietary score also includes a standby battery draw test, which is not featured in our test scorecard but is calculated in the total endurance rating.

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.
