How does OnePlus 6 compares to iPhone 6s Plus

With the recent launch of OnePlus 6 globally, we had been bombarded with tons of queries on how it compares to iPhone 6s Plus. Yes you heard it right, the phone which was launched back in 2015. And why are we comparing these, well it's the economics this time. Both OnePlus 6 and iPhone 6s Plus are trading at ₹35,000 (USD 518) and ₹37,000 (USD 547) respectively for their base variants. Both are incredibly capable devices, one giving the entry into the Apple's eco-system and the other bringing you the latest of the technology.

Phone DisplayPerhaps the most important part of the mobile phone serving as window to access all your virtual content including news sites, emails, videos, etc. The mobile screen are physically measured in inches and it's resolution in PPI (Pixels Per Inch).  We usually prefer screens with larger display sizes and better PPI. The higher the PPI, the crisp the image would be. The text would appear much cleaner and sharp and videos up to mark.

Besides the PPI another consideration with screen is type of screen. There are two kinds of screen, LCD-TFT or AMOLED. There are other kinds as well but we are leaving them off for this comparision. LCD display has been found in almost all devices today, they work on the principle of backlight illumination to paint your image. They usually tend to be more power hungry and have limited contrast. AMOLED on other hand has been made from electroluminescent material which tends to glow themselves without needing a backlight to paint an image. They tend to conserve power as the necessity of backlight is eliminated and since each pixel can be turned off or made black, they tend to be having higher contrast ratio.


iPhone 6s Plus
  • 5.5" Retina HD Display with 3D Touch (Retina Display is Apple's marketing term for higher PPI displays)
  • 1920x1080 resolution @ 401 ppi
  • 1300:1 contrast ratio
  • LCD Multi-Touch display
  • Sapphire glass treatment
OnePlus 6
  • 6.2" corner to corner screen. (It has thin bezel, i.e. frame, just like iPhone X)
  • 2280x1080 resolution @ 402 ppi
  • Infinite contrast ratio
  • Optic AMOLED display mostly sourced from Samsung
  • 2.5 Corning Gorilla Glass 5

The OnePlus 6 clearly has a larger screen than iPhone 6s and covers corner to corner which should be pleasant to look at. It has AMOLED display panel with equivalent PPI. AMOLED, as we said before, helps save battery but it has inherent problem to show over saturated colors. Though the effect is slightly less prominent on OnePlus 6.

On the other hand we have Apple's Retina HD display, one of the most innovative of it's time with more natural colors but with time has come little dated.

CameraMobile cameras have almost killed the market for point and shoots. Nowadays they are have excellent lens & image sensors with ton of software pre-processing to get you the best. Usually we measure the cameras in MegaPixels. MegaPixel is the measure of how many pixels (dots) the image sensor captures which in-turn define dimension & size of your picture. It's a general myth that higher MegaPixel is better but usually what matters the most is the quality of Image Sensor, Lens, Stabilization, low light response and post processing. Another important aspect is aperture size, i.e. amount of light allowed to enter the image sensor, usually larger is better and good for low light photography.

There are two kinds of cameras on mobile phones (nowadays it's three kind). The rear camera, nowadays coupled with lens to capture depth. And the front or selfie camera. Usually the rear cameras have higher MegaPixel and better sensor. The front cameras are most used for selfies or video chatting.

  • f/2.0 aperture


  • 1080p (Full HD) @ 30 fps
  • 720p (HD) @ 30 fps
  • Time Lapse

It's quite evident that iPhone 6s has started showing it's age in the camera department. In no way it's less capable and one of the best quality image sensors but certainly misses the features like Telephoto lens, Potrait mode, etc. It has wider aperture which can help with low light photography.

On the other had OnePlus 6 seems to be filled to brim with features. Two rear cameras both having quality Sony Image Sensors and way higher megapixel than iPhone. You can use Telephoto or capture portrait. With two cameras, one capturing depth or additional details, the low-light photography should be excellent. It could shoot 4K video @ 60 fps and Super Slow Mo 720 @ whopping 480 fps! It is unclear however whether it supports image stabilization while shooting video.

Connectivity & Location

WiFiConnectivity is the paramount aspect of any phone. After all you have bought the phone for being connected, no? There are various kinds of connectivity on the phone. Telephony chip (2G, 3G, 4G), Bluetooth, WiFi and NFC. Your phone uses them to either connect to the cellular network or to a WiFi or to another device as well as charge or make digital payment.

Besides connectivity, there is GPS Receiver to determine your location. GPS has become synonymous to location however it stands for Global Positioning System and is network of satellites commissioned by the US for determining location for military purposes. It was made available to general public in the year 2000. Your device can connect may such GPS systems, like GLONASS, Galileo, etc. Using location you can get turn-by-turn navigation on Google Maps & Apple Maps.


iPhone 6s Plus


  • Supports nearly all LTE (4G), 3G, 2G bands
  • 802.11ac Wi-Fi with Multiple In and Multiple Out configuration
  • Bluetooth 4.2 with NFC


  • A-GPS, GLONASS, Galileo and QZSS
  • Digital Compass
  • iBeacon micro-location

Qualcomm chipsetThe performance of the phone is usually measured by the chipset or SOC it supports. SOC stands for System On Chip which basically is circuitry which encompasses all what it makes to be a computer. The usual components is CPU, GPU, RAM, Memory, Wireless, Telephony, Storage etc. Amongst these, the component that makes a markable difference is CPU, GPU & RAM. The more the processing power, the more complex or multi tasking applications can be run. You can play ultra HD games or record 4k videos. The power of CPU is measured in Gigahertz which roughly translates to 1 trillion floating point operations per second. The CPU can have one core or multiple. Having multiple core in theory can let multiple applications run together simultaneously. Nowadays the CPU contains 4, 6, 8, 10 cores all packed in different configurations.

Similarly, GPU is responsible to draw images on your screen. The powerful the GPU is the faster the complex images can be drawn. GPU power is also measured in Gigahertz however it tends to have much higher number of specialized cores than CPU and usually runs at lower clock speed (gigahertz). Powerful GPU along with more RAM can make gaming a breeze.

RAM stands for Random Access Memory which serves as ultra fast store of data & instruction those are needed by the CPU & GPU. Even RAMs have clock cycles albeit much slower compared to CPU/GPU. The larger & faster the RAM the better.

Then comes our beloved Storage. Storage is basically your Hard Disc where you can store your songs, pictures taken from camera, your downloads, etc. The Storage comes in two configuration, Phone Storage and Removable Storage. No all Phones support Removable Storage in which case you are limited to the storage available on your phone. More the storage, more content you can save locally to your phone.

iPhone 6s Plus
  • Dual Core, 1.8 GHz, 16 nm, Apple A9 processor
  • 64 bit architecture
  • PowerVR 7XT GT7600 GPU with six cores
  • M9 motion coprocessor
  • 2 GB RAM
  • 16/32/64/128 GB Phone Storage
OnePlus 6
  • Octa (8) Cores. 2.8 GHz, Snapdragon 845 (SDM845) processor
  • 64 bit architecture
  • Adreno 630 GPU
  • 6/8 GB RAM
  • 64/128/256 GB Phone Storage

Apparently the SOC on OnePlus 6 is much latest, leading with 8 cores on CPU and about 2. 8 GHz clock speed clubbed with Adreno 630 GPU. This simply blows iPhone 6s out of proportions but again we are comparing a recent released product to one which was released 3 years back. RAM wise again OnePlus 6 blows it out with huge margin. Even the basic variant has 6 GB of RAM which is enormous.
