While the two new handsets come in different sizes, they have a lot in common under the hood. For starters, they offer the same 1,920 x 1,080 resolution, translating to 445 pixels per inch (PPI) on the R7 and the 367 PPI on the R7 Plus.
The trend continues when you get down to the internals, with both smartphones running on a Qualcomm Snapdragon 615 processor backed up by 3 GB RAM. There are 13 and 8 MP cameras on the front and back of the handsets that the company claims are able to produce good low light shots and effect-laden selfies.
The R7 Plus packs more internal storage than the R7 (32 GB vs. 16 GB), but both devices feature microSD card slots, so upping available space for storing media shouldn't be a problem. The larger handset also offers a higher capacity battery than its little brother (4,100 mAh vs. 2,320 mAh). Neither device's battery is removable.
On the software side of things, both handsets feature Oppo's own ColorOS 2.1, but while the R7 Plus offers Android 5.1 Lollipop, the smaller handset makes do with the 4.4 KitKat version of the platform.
Oppo has packed quick charging tech into the devices, and claims that you'll be able to get around 75 percent of a full charge in just 30 minutes. The R7 Plus also features a fingerprint sensor on the back that allows the user to unlock the device with the press of a finger (that didn't work so well on the HTC One Max, but we'll wait and see how Oppo's implementation goes). There are also dual SIM card slots on both handsets – something we're used to seeing on devices from this part of the world.
While the above specs call the devices out as mid-tier offerings, Oppo has made a significant effort with the design, slimming down the handsets to just 6.3 mm (0.25 in) on the R7 and 7.75 mm (0.3 in) on the R7 Plus. The aluminum unibodies look sleek and clean, if not wildly different from anything we've seen before. The front on both devices curved down slightly at the sides, though the effect looks a little nicer on the R7 Plus, which features an edge-to-edge-display design.
Both devices are launching this week in China, priced at 2,499 yuan (US$400) for the R7 and 2,999 yuan (US$480) for the R7 Plus. There's no word yet on when we'll see the devices hit other regions.
