Apple iPhone 6s vs Samsung Galaxy S6 vs Galaxy S6 Edge : Detailed Comparison

Apple iPhone 6s vs Samsung Galaxy S6 vs Galaxy S6 Edge (1)

Look, Design and Feel

Apple iPhone 6s : 7.1mm thick, weighs 143g

Apple has built iPhone 6s on the lines of iPhone 6, keeping the overall look and feel of the device identical to the predecessor apart from minor changes such as the minimal increase in overall thickness of the smartphone in order to let go of the infamous Bend-gate and also, due to the in-cooperation of 3D touch panel. All in all, a fantastic design language that still gets many hearts pumping, specially with the new Rose Gold color option.

Samsung Galaxy S6 : 6.8mm thick, weighs 138g

Samsung might have tried well-and-hard to break free from the iPhone rip-off design language, failing so much so that at a distance, the S6 still seems to be inspired heavily by the iPhone 6s. Be it the mettle-and-glass treatment that first appeared on iPhone 4 or the Antenna bands or the speaker grills, Samsung seems to lack inspiration. Mind you, all of this is true only when we compare the iPhone and the Galaxy device side-by-side. What Samsung has otherwise came out with Galaxy S6 is a device that surely boasts the best design Samsung has ever mated any of its flagship to largely due to Samsung Project Zero that has aimed to bring up radical design changes, keeping in mind both the customer reviews and the likable previous-flagship aesthetics.

Samsung Galaxy S6 Edge : 7.0mm thick, weighs 132g

Just like Samsung rose above the competition with its distinctive Note range, Samsung seems to have found another winner with this Edge smartphone range that features dual-curved display at both sides of the screen that seems to inspire more of a infinite display-like screen that delves into the glass and mettle frame ever so flawlessly. Except this, the S6 and S6 Edge share most of their hardware components, both on the inside and outside.

Winner : Personal Preference


Apple iPhone 6s : 4.7 inches, 750 x 1334 pixels (~326 ppi pixel density)

On papers, Apple’s aging Retina display doesn’t even stand a chance to compete with what Samsung has in-cooperated on its flagship, but in real-world, the display seems to fare out well enough to leave its users with crisp color reproduction, viewing angles and under-sunlight legibility. Also, with the 3D touch support now embedded, iPhone’s display brings in a whole new capability to how a smartphone’s display behaves and differentiates across various taps and touches based on their sensitivity.

Apple iPhone 6s vs Samsung Galaxy S6 vs Galaxy S6 Edge (2)

Samsung Galaxy S6 : 5.1 inches, 1440 x 2560 pixels (~577 ppi pixel density)

High on resolution, high on pixels, high on Battery consumption. That’s the story of this ultra-beautiful display that leaves its users mesmerized. Be it the sheer perfect color reproduction, touted to be over-saturated by many, or the darkest blacks on a smartphone display, Samsung has crafted a gem of a display. Sadly then, all of this comes powered by a battery that seems insufficient to with-hold such power-hungry display.

Samsung Galaxy S6 Edge : 5.1 inches, 1440 x 2560 pixels (~577 ppi pixel density)

This is where Samsung has taken giant leaps. The ‘infinite’ dual-edge curved display that comes packed with oozing pixels and ultra-clear picture reproduction, the S6 Edge scores heavily over the iPhone 6s and even its sibling S6 on the display front to say the least. What further exaggerates the usefulness of such a brilliant display is the set of additional functionalities and features it comes powered with, such as Information Stream and Edge Lightning.

Winner : Samsung Galaxy S6/S6 Edge

Processor and Performance

Apple iPhone 6s : Apple A9 Chipset, Dual-core 1.84 GHz CPU with 2 GB RAM

The biggest and the most sought after hardware that has been added to this ‘S’ moniker flagship is the upgradation of RAM to 2GB to compared to 1GB on iPhone 6 along with an updated A9 chip that claims to bump up the CPU & GPU performances by 70% & 90% respectively. While these under-the-hood upgrades do offer help to make the iPhone 6s a lot more snappier, it’s more about the iOS that gives it the overall polished feel, resulting in the most stutter-free and crisp performance overall.

Samsung Galaxy S6 : Quad-core 1.5 GHz Cortex-A53 & Quad-core 2.1 GHz Cortex-A57 CPU, Exynos 7420 Chipset with 3 GB RAM

With 4-cores clocked at 2.1 GHz and the other 4 at 1.5 GHz, Samsung Galaxy S6 is nothing short of a powerhouse. S6 makes the most of its under-the-hood hardware beasts by powering a display flooded with pixels and a camera setup that’s beyond excellence flawlessly enough. Also, with 3GB RAM onboard, you can multi-task well enough only to find yourself face some weird hiccups, thanks to the bloatware Samsung still pushes across with its Galaxy devices.

Samsung Galaxy S6 Edge : Quad-core 1.5 GHz Cortex-A53 & Quad-core 2.1 GHz Cortex-A57 CPU, Exynos 7420 Chipset with 3 GB RAM

Keeping the internals unchanged to those on the S6, S6 Edge offers near equivalent performance. The major difference comes only to the display section wherein the dual-curved display offers added functionalities along with the bragging rights for a phone that simply stands out for its appeal.

Winner : Apple iPhone 6s

Operating System/Software

Apple iPhone 6s : iOS 9

This is where it all comes down to. iOS vs Android! Security vs Compatibility! Intuitive UI vs unnecessary Bloatware! Well, it really comes down to personal preferences to choose among these 2. Well, one thing’s for sure, with iOS 9 and 3D touch capabilities embedded on iPhone 6s, Apple holds the edge largely due to addition of a whole new dimension of tracking the pressure sensitivity in order to distinguish between a light tap and a hard tap, thus enhancing the interactive capabilities. Also, with the most slick iOS to date and the reliable security iOS comes bound to offer, iOS for iPhone 6s works like a charm.

Samsung Galaxy S6 : Android Lollipop OS with TouchWiz UI

Old same story. A beast of a device with top-of-the-line internals, a re-invented design language and the World’s most famous OS on hands only to be marred by the bloatware Samsung’s TouchWiz UI infects this ultra-powerful device with. Mind you, both the Android, with Android Lollipop, and the TouchWiz UI are at the top of their game right now offering the most slick UI they ever have been till date, still, there’s nothing that can beat the Stock Android’s flawlessness and overall-polished feel, not even iOS perhaps.

Samsung Galaxy S6 Edge : Android Lollipop OS with TouchWiz UI

For all the minuses- Same as above. What then sets S6 Edge apart is the additional functionalities its curved display brings along.

Notifications and messages can be accessed from the edge using the new ‘People Edge’ mode wherein you can set upto 5 contacts and have shortcut access to them via swiping gesture on the Edge of the display. You can even set a specific color to flash when a particular person calls. The edge on the display can also double up as a bedside clock with Night Clock mode ‘On’. These functionalities to some extent do extend the capabilities a flagship device is expected to offer, bring in various new dimensions with the dual-curved edge display.

Winner : Personal Preference


Apple iPhone 6s : 12 MP, 4032 x 3024 pixels, phase detection autofocus, dual-LED (dual tone) flash rear camera, 5 MP front facing camera

Bumping the camera setup from 8MP to 12MP for Rear camera and 1.2MP to 5MP for front snapper, iPhone 6s offers improvements not only on the hardware front but a plethora of them on the software front. Be it the Retina flash, that lights up the screen up three times brighter that normal, touted to help you take brighter selfies in dim light or the Live Pictures that help you capture a second-and-a-half both before and after a picture is clicked and animate it later, Apple has tried to regain lost ground in the Camera department. But then, the lack of Optical Image stabilization that features on the Galaxy flagships and even its bigger sibling- 6S Plus is dearly missed. Still, by no stretch of imagination can the iPhone’s camera prowess be considered to be filthy largely due to the intuitive UI iOS’ camera app has, plus all the minor under-the-hood improvements that result in better image reproduction, shutter-speed and overall stability.

Samsung Galaxy S6 : 16 MP, 2988 x 5312 pixels, optical image stabilization, autofocus, LED flash rear camera, 5 MP front facing camera

Well, same old story. Samsung has been giving Apple’s renowned Camera setup  a run for its money ever since but what makes Apple’s camera standout is it intuitive and crisp nature, as briefed above. But then, zoom into the pictures taken by S6 and iPhone 6s side-by-side and surely Samsung comes out with better detailed pictures in both natural & low-light photography. The over-saturated colors on the photos might well dent the natural colors, but then, they are so pleasing to the eyes that you surely can’t hate it. Well, a close call on the rear-camera setup for sure, slightly in S6′ favor! For the Selfie cameras then, Apple has a prolific camera setup that Samsung still can only dream of competing. Be it the various color modes or the added ‘Retina Flash’, iPhone’s Selfies still earn those bragging rights, authoritatively.

Samsung Galaxy S6 Edge : 16 MP, 2988 x 5312 pixels, optical image stabilization, autofocus, LED flash rear camera, 5 MP front facing camera

An unchanged camera setup to that on the S6 makes little to no difference in the overall camera quality.

Winner : Samsung Galaxy S6/S6 Edge

Battery life

Apple iPhone 6s : Non-removable Li-Po 1715 mAh battery

What makes up for a battery that’s strangely cut down to smaller capacity as compared to the predecessor, iPhone’s battery still claims to get you through a day without charge. A better battery management aesthetics with detailed battery consumption details drawn app-wise plus a Low-Power mode that claims to increase the overall battery backup by 2-3 hours, iPhone’s battery does have the upper hand on the Samsung flagships for sure.

Samsung Galaxy S6 : Non-removable Li-Ion 2550 mAh battery

A larger screen and a battery-hungry processor to feed to, Samsung’s S6 does fall short with a very moderate battery backup. But where Samsung scores heavily is the support for both wired and wireless charging options plus faster-charging technology that gets the S6 faster out-of-the-block with upto 20% battery charge for mere 10 minutes of charging.

Samsung Galaxy S6 Edge : Non-removable Li-Ion 2600 mAh battery

A slightly bigger battery, perhaps for the little curved edges? Well, it still disappoints like its sibling Galaxy S6 to say the least.

Winner : Samsung Galaxy S6/S6 Edge (for faster charging & both wired & wireless charging options)

Apple iPhone 6s vs Samsung Galaxy S6 vs Galaxy S6 Edge – VERDICT

First up, there’s no doubt that all of these 3 devices are hugely powerful, hugely popular and consequently, would be sold in Millions. What we try and bring to you, here at GeekViz, is the first-user review for all of these flagships to help you steer clear of any doubts, conceptions or indecision you might be facing to find out the best of the lot. While all of these flagships try and improve on there predecessors shortfalls, they are still found wanting on various issues that need to fixed ASAP! For iPhone’s, it’s time Apple considers a serious update to its aging Retina display to stand a chance to compete with the ones fitted on the Samsung flagships plus improvements such as faster-charging technologies and dumping 16GB entry model. Samsung then seems to be going two-steps-forward-one-step-back by letting go of the removable battery, expandable storage and water-resistance capabilities. Also, the long overdue call for Samsung to stop infecting its ultra-powerful devices with the stupid TouchWiz bloatware has had no ears so far. But where Samsung’s S6 then outclasses iPhone 6s is the better display quality, redefined design language and a prolific camera setup, only to be exaggerated on the S6 Edge with dual-curved display doubling up to offer extensive list of features such as the new ‘People Edge’ mode wherein you can set upto 5 contacts and have shortcut access to them via swiping gesture on the Edge of the display, setting up specific colors for the ‘Edges’ to flash when a particular person calls or using these Edges as a bedside clock with Night Clock mode ‘On’. Apart from this, there is little to no difference in the way both S6 and S6 Edge behave and respond in Real-world, except for the additional cost S6 Edge comes with. Coming to iPhone 6s, Apple manages to improve on its forte with ever-so-slick and polished iOS plus the new 3D touch setup that in-cooperates new dimension of touch based on the sensitivity of touch made. In a nutshell then, all of these smartphone do improve on their predecessors in a certain way and are still the best flagships you can choose from with all of it coming down to personal preferences amongst the iOS and Android.
