Oppo R1x review: Sleek geometry
Solid 720p 5-inch display
The display on the Oppo R1x is a 5-inch IPS unit of HD resolution. Not a record breaker, the panel still manages a respectable 294ppi. To be fair, there are competitors with 1080p resolution at this price point. Our microscope shot revealed a standard RGB subpixel arrangement.
The panel does have its virtues though, among them the great viewing angles. Even at the extremes, the display remains clearly legible, color stability is excellent and there's only the slightest drop in contrast.
Color rendering is quite accurate, no over-saturation. We try to make that sound as a compliment, but fans of that vibrant AMOLED look may not be pleased. There're no color adjustment options in the settings, it is what it is.
The test results aren't overly impressive though. At maximum brightness, whites are around the 500-nit mark, which is on the high side of average. On the other hand, the highly lit blacks make up for a rather low contrast.
The adjustment slider is virtually linear, and the 50-percent setting halves the illumination of both the whites and blacks, resulting in practically the same contrast.

| 0 | 191 | ∞ | 0 | 398 | ∞ | |
Despite the less than stellar numbers for brightness and contrast, the R1x posted a decent result in the sunlight legibility test.

Connectivity
The Oppo R1x has all your basic connectivity needs covered. It's a dual-SIM dual-standby device with both cards supporting quad-band 2G, while SIM1 also supports penta-band 3G and tri-band LTE.
The smartphone has Wi-Fi 802.11 b/g/n only in the 2.4GHz spectrum, but does have Wi-Fi direct and hotspot. Bluetooth is the 4.0 iteration, with A2DP enabled for audio streaming. There's no NFC, nor is there an FM radio.
There's GPS with GLONASS support, but no A-GPS for precise positioning over cellular.
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. A standard 3.5mm jack completes the wired connectivity package.
Battery life test
Oppo has equipped the R1x with a 2,420mAh battery, which is about average for 720p 5-inchers these days. The Sony Xperia M4 Aqua has virtually the same capacity at 2,400mAh, while the Samsung Galaxy A5 has 2,300mAh. The battery is non-removable.
Oppo doesn't have a terribly good track record in our battery tests, and we approached the R1x with caution. The results were varied.
Its 3G call endurance wasn't particularly impressive at around 12.5 hours, but it's still more than 50% better than the modest 8 hours quoted by the company, so we could count that in the R1x' favor.
As part of our standard battery tests we measure standby time as well, and although it's not explicitly stated on the scorecard, it's taken into account in the overall rating. It was not too good either, with a dual-SIM time just shy of 7 days.
On the other hand, both video playback and web browsing are around the 9-hour mark, which is a very good achievement. Overall, if most of your interaction with the R1x happens with the screen lit up, you should be more than satisfied with its battery performance.
