Let’s get into the details then, shall we?


The design of each of the three phones reminds us of their respective predecessors, but have been upgraded substantially.

The OnePlus 5 takes most of the design structure of its predecessor, the OnePlus 3T, and upgrades it a bit, with a few tweaks here and there. Most notable amongst them are rounder corners and edges, rehashed antenna bands, and a dual camera setup on the back (which seems simliar to iPhone 7 Plus).

The Mi 6 moves on from the metal and glass finish of its predecessors (the Mi 5s and Mi 5, respectively), and is fashioned from 3D curved glass on all sides, which makes seamless transition with the stainless steel frame. Yes, it is a fingerprint magnet (and a bit slippery, too), but unless you want to risk scratches and bumps, a simple case would ease the anomaly.

For the G6, LG has let go off the controversial meta-sprayed plastic that the G5 came with, and improved the aesthetics of its flagship for the year, in all aspects. The G6 comes with a rather uncommon 18:9 ratio, and a 5.7-inch display that takes up about 80% of the front panel. We quite like the sturdy-yet-classy design of the phone, personally.

Then again, the design of a smartphone is indeed quite subjective, and differs from person to person. So, we’d let you infer from your personal preference here.


True to their flagship status, the trio comes loaded in the display department.

The OnePlus 5’s display mirrors what the OnePlus 3T sported – a 5.5-inch display size with 1080x1920p resolution and an AMOLED panel. The addition of the DCI-P3 gamut would be helpful in the reproduction of the UltraHD content in the future.

The G6, on the other hand, has the largest-of-the-lot (also including the PPI and screen-to-body ratio) 5.7-inch QHD display, which, going by LG endeavors in this field, works efficiently and helps the phone exude vibrant colors. Also, the G6’s compatibility with HDR 10, as well as the presence of an ‘Always On’ display is a huge plus point.

The Mi 6 is smallest in this aspect, but its 5.15-inch fullHD display does a great job, and manages to give off an AMOLED-like result despite having an IPS LCD panel. This factor would help win over users who would otherwise be unhappy with the presence of the latter in a flagship.


Everytime you introduce a smartphone as your flagship device for the year, you absolutely need to ensure that it comes good on the performance front. These three? Up there at the top.

All of the three come booting Android Nougat out of the box, with their company’s own skins layered on the top – OxygenOS for the OnePlus 5, UX UI for the G6, MIUI for Mi 6.

The G6, being the oldest here, makes use of a quad-core Snapdragon 821 chipset, one of the better ones introduced this year, combined with an Adreno 530 GPU and 4 gigs of RAM. Yes, this is one formidable combination indeed.

Meanwhile, the same octa-core Snapdragon 835 and Adreno 540 GPU (both highest in their class presently) setup is followed by both the OnePlus 5 and the Mi 6, making them more than efficient in this department, too. OnePlus with 6GB and 8GB RAM is slightly better in terms of multi-tasking and day to day performance.

Camera and Battery

What good is a flagship, if it fails in the optics department, isn’t it?

The three companies surely agree and that is why they have put in top of the line optics in their respective 2017 flagships. All of them feature a dual camera setup at the back, but their setup is different from one another.

The OnePlus 5 has a 16MP lens combined with a 20MP telephoto one on the back, with features including dual-LED flash, 2x optical zoom, and phase detection autofocus. That the newest Oneplus flagship does not possess OIS is a bit of a dampener, but it does make use of an EIS (which works exceedingly well for Google Pixel).

The G6 has a set of two 13MP cameras on its rear, with features that include phase detection autofocus, dual-LED flash, OIS etc. We know of LG’s affinity towards optics, and it is hence no wonder that we found the G6 to be better than the other two here (albeit by a very thin margin).

Similarly, Xiaomi’s flagship contender has dual 12MP cameras donning the back side, that have a 2x lossless zoom, OIS, dual-tone LED flash, face detection, HDR to name a few. The company has chosen to incorporate a combination of a telephoto lens and a wide-angle lens rather than going the conventional way (RGB + monochrome) following the iPhone 7 Plus’ lead.

Up front, the Oneplus 5’s 16MP (f/2.0, EIS (gyro), 1.0 µm pixel size, 1080p, Auto HDR) selfie snapper dominates the proceeding against the other two – 5MP (G6) and 8MP (Mi 6).

As for the battery, the trio does not have much of a difference, with the OnePlus 5 and G6 both having 3,300mAH-rated ones, while the Mi 6 has a 3,350mAh one.

Also, both the G6 and the Mi 6 come in boasting of Quick Charging 3.0 support, while OnePlus’ dash charging capabilities need no introduction.

If we were to single out a winner here, it would be the Mi 6 (largely thanks to its relatively smaller size, and the presence of Quick Charging 3.0 support).
