In this article, we compare the OnePlus 2 with industry's renowned flagships, the Samsung Galaxy S6 and the LG G4, to see where the newly launched handset stands.

OnePlus is promoting OnePlus 2 smartphone as the "2016 flagship killer".

By comparing individual specs of OnePlus 2 with its rivals, we try to come at a conclusion of whether it is worth making the jump to the Oxygen OS-based handset.


Big screens are in. Consumers are looking for smartphones with 5-inch screens and above and manufacturers are catering to their demand.

The OnePlus 2 smartphone was launched with a 5.5-inch Full HD (1920 x 1080p) screen with a pixel density of 401ppi. Comparatively, the Samsung Galaxy S6 features a 5.1-inch Super AMOLED display with Quad HD (2560 x 1440p) resolution and 577ppi, highest pixel density in the industry.

The LG G4 packs a screen size similar to the OnePlus 2, measuring 5.5 inches and matches the screen resolution of Galaxy S6 with its Quad HD screen.


A good camera in a smartphone always comes in handy. The OnePlus 2 packs a 13-megapixel rear-facing camera with f/2.0 aperture and a dual LED flash.

As for Samsung's flagship, the Galaxy S6 features a 16MP primary shooter with LED flash and f/1.9 aperture, which is the same as the LG G4 but even lower f/1.8 aperture for LG's flagship.

On the front side of the devices, the OnePlus 2 and the Samsung Galaxy S6 pack identical 5MP sensors, while the LG G4 is a step ahead with its 8MP shooter.


All three smartphones have different type of processors. Samsung takes the lead with its home-grown Exynos 7 series Quad 2.1GHz + Quad 1.5Ghz octa-core SoC, which has the highest benchmark score in the industry.

On the other hand, OnePlus and LG borrowed their chipsets from Qualcomm. The OnePlus 2 is powered by an octa-core 64-bit Qualcomm Snapdragon 810 v2.1 SoC while the G4 smartphone gets treated with a 1.8GHz 64-bit hexa-core Qualcomm Snapdragon 808 chipset. Given the high-end processors, you can bank on any handset for an exceptional lag-free performance.

RAM and Storage

The Samsung Galaxy S6 is supported by a 3GB LPDDR4 RAM while the LG G4 packs 3GB RAM based on LPDDR3 architecture. The OnePlus 2 takes the lead in the RAM department as it houses 4GB LPDDR4.

In terms of storage, LG G4 packs 32GB internal storage with an option to expand using microSD cards while the OnePlus 2 and the Galaxy S6 have different storage variants. The OnePlus 2 comes with either 16GB or 64GB storage options and the Galaxy S6 offers 32GB/64GB and 128GB variants.


All three smartphones are powered by Google's latest Android Lollipop operating system. The LG G4 customizes the OS with its new human-centric UX 4.0 to include features such as Quick Shot, Smart Notice, Event Pocket and more. The Samsung Galaxy S6 comes with its own TouchWiz UI. As for OnePlus 2 smartphone, it runs an entirely different OxygenOS based on Android 5.1 Lollipop.


The OnePlus 2 leads in the battery department. The combination of a 3,300mAh battery along with use of LPDDR4 RAM guarantees lasting smartphone usage. Comparatively, the Samsung Galaxy S6 packs a 2,500mAh non-removable battery and the LG G4 gets a 3,000mAh unit.


In line with their brand image, the Samsung and LG flagships are expensive. The LG launched its G4 smartphone in India for Rs 51,000, while the Samsung Galaxy S6 was launched at Rs 49,900 for the 32GB model, Rs 55,900 for 64GB and Rs 61,900 for 128GB. Although the current prices for both the flagships have dropped since the release, they still fail to match the competitive price of OnePlus 2.

The OnePlus 2 16GB variant costs ₹22,999 while the 64GB model sells for ₹24,999.


Both Samsung Galaxy S6 and LG G4 smartphones are available through various online and offline channels. But the same cannot be said about the OnePlus 2, which is sold only via invites.

The company will send out invites to registered buyers before they can get the handset, which can be quite a turn off for those who lack patience.
