The Galaxy S6 was the headline-grabber at Mobile World Congress mostly because of it’s bold new look. How does the GS6 build off the GS5? Is the phone the answer to Samsung’s smartphone woes? We pit the Galaxy S6 against the Galaxy S5.

Processor and architecture

For Samsung loyalists, 2015 will be remembered as the year Samsung parted with the Qualcomm processor. We’ve entered the era of the Exynos octa-core processor. How it stacks up against Qualcomm’s Spapdragon is only speculation at this point. No doubt, the expectations are high for Samsung’s new 64-bit octa core chip. We’ll keep you updated on the how the new processor stacks up.

Aside from the upgraded processor, Samsung has included 3GB of RAM (that’s a whole gigabyte more than the GS5) and boosted the internal storage capacity starting at 32GB. The added storage and RAM will make the GS6 one of the most powerful devices on the market. This isn’t really a surprise to anyone. On the other hand, Samsung has omitted an SD card slot, no doubt, in an effort to make a slimmer and more attractive handset.

Design and resolution

Overall, the GS6 is one of the best looking phones out there. The slimmer profile and aluminum bumper and glass rear panel make for a more premium looking Galaxy phone. The camera does stick out slightly from the rear panel, but that’s forgivable these days because, well, even the iPhone does it. So is the non-water resistant chassis, which Samsung has done away with for the GS6. Sadly, few new phones are waterproof this year due to an increased reliance on metal styling.

Samsung also upped the GS6 resolution. At 2,560 x 1,440 pixels, the SG6 fits into the category of Quad HD resolution with about 30 percent higher pixels density than the GS5.

Another yet-to-be-seen feature is GS6’s battery. It’s where specs don’t always tell the full story. While the GS5 had some nice features that were omitted from the GS6 (including a removable battery and larger battery size), Samsung has included a rapid charge feature that is estimated to give your phone about 4 hours of battery life with a 10 minute charge. When you add that to Samsung’s brand new processor (jury is out on its efficiency) and Android 5.0, which sips battery better than older iterations of Android OS,  and standard wireless charging feature for every GS6, it’s clear that the GS6 has thought through the battery game.


The GS6 improves upon an already stellar camera offered from the GS5. Most important, the “selfie” front camera has been upgraded to a 5-megapixel shooter from 2.1 megapixels, which puts in on par with other Android superphones.

The merits of a great camera surely don’t come down to just megapixels, though, and the GS6 has a couple of new advancements designed to make the most of the rear 16-megapixel shooter. For starters, now GS6 users can simply double tap the Home button and be transported to the camera app in less than a second. It’s a great feature that’ll take some of the angst out of candid photos. The rear camera also has optical image stabilization and a larger f/1.9 aperture that will take wider shots.

Both devices also tout the ability to capture HDR images and video, but the GS6 has an auto-HDR feature that’ll shoot with consistently better photo quality.


The bottom line is this: Samsung’s new handset is a beauty. It’s decision to make a beautiful device come with a several trade offs. Leaving out the SD card, removable battery, and water-resistant chassis are disappointing. However, it’s a small trade off for most of us who are thrilled that Samsung stepped up its design game. This is one of the most elegant handsets of 2015 so far.
