Galaxy S7 vs S6 vs S5: Should You Upgrade?

With last year’s Galaxy S6, Samsung’s flagship line took a big step forward in design and performance, with a well crafted aluminum frame, attractive yet durable glass panels on front and back, Samsung’s homegrown Exynos 7420 chip and blazingly fast storage speeds.

Samsung also introduced the S6 Edge, the first phone featuring a display with usable curved edges. It wasn’t wildly different from the standard S6, but it changed the way people, and other companies, thought about designing a smartphone.

But those improvements didn’t come without sacrifice, as certain features of older Galaxy S phones —including water resistance and a microSD slot — were missing from the S6 and S6 Edge. The S7 and S7 Edge restore those missing features.

Here’s an in-depth comparison to help you figure out what’s new — and what’s old — on the S7 and S7 Edge, and if it’s worth upgrading from an S6, S5 or older Samsung model.

The Specs


The big hit from last year’s Galaxy S6 launch was the curved-screen S6 Edge, which was so popular early on that Samsung couldn’t make enough to keep them in stock. But aside from the seductive curved screen, the S6 Edge wasn’t that different from the regular S6. Its 2560 x 1440 display was same overall size (5.1 inches), and its battery was larger by only 50 mAh. But for the S7s, there’s much more of a difference between the standard phone and its edgy sibling.

On the S7 Edge, the screen size has jumped to 5.5 inches, while the standard S7 has stayed put at 5.1 inches. Along with the bigger display, the S7 Edge features a significantly larger 3,600 mAh battery, almost 40 percent larger than the 2,600 mAh power plant in last year’s S6 Edge.

Speaking of edges, the size of the S7’s curved display space has doubled from 260 pixels wide on the S6 Edge to 550 pixels on the S7 Edge. That creates room for a second row of Edge apps, along with the ability to make simple macros that can do things like email a specific person or take a selfie with one touch. Samsung has said it will open up the Edge apps’ API, so we can expect third-party side-mounted software in the future.

The result is two S7s that have much more variety between them than the twin S6s from last year. The standard S7 is a good choice for people who prefer smaller phones, but want all the bells and whistles that a new generation of flagship phones has to offer. The S7 Edge, on the other hand, should attract buyers willing to pay a bit extra for looks, handy extra apps, and a better, more immersive media experience.

Both the S6 and S7 are far superior to the S5 in terms of feel and design. It was the plastic body on the S5 (and previous Galaxy phones) that drew criticism about how Samsung’s flagships didn’t feel very premium in 2014 compared to other phones, such as the HTC One M8.


The S6 Edge is one of the best-looking phones in tech history, and on the S7 Edge, Samsung wisely has stuck pretty close to last year’s formula. The company has done a little tweaking to smooth out certain corners and better integrate the fingerprint reader, but you’re still getting a very similar-looking phone, with a metal frame around the outside and glass panels on both front and back.

The more important changes have taken place beneath the skin. On the S7 line, Samsung has brought back the microSD card slot and water resistance last seen on the Galaxy S5. The S7s’ IP-68 ratings are a notch up from the S5’s IP-67 rating, and means both the S7 and S7 Edge can withstand depths down to 5 feet for up to 30 minutes.

The microSD slot built into the S7s’ SIM trays support 200GB microSD cards, much larger than the 128GB limit on the S5. Card reads and writes should also be faster, because the S7 line uses a speedier UFS 2.0 file format. To respond to critics who said Samsung neutered its flagships last year, all the features you may have loved on the S5 are back — other than the S5’s removable battery.


On the S7 line, Samsung has shifted back to Qualcomm CPUs with the Snapdragon 820, after having used one of its own chips, the Exynos 7420, for the S6. (The S5 featured the Snapdragon Qualcomm 801.) The Galaxy S7 phones also have 4GB of RAM, versus 3GB for the S6 and 2GB for the S5. Combined with the new Snapdragon 820, that boost in memory should offer markedly better performance than the S6 line, both in browsing the Web or playing mobile games — no mean feat.


At first glance, the camera specs on the S7s might lead you to think Samsung had regressed, because the new phones feature 12-megapixel rear cameras versus the 16-MP cameras on the S6s and S5. But resolution isn’t everything. While the S7 cameras have fewer overall pixels, each pixel measures 1.4 microns, as opposed to 1.12 microns on the S6 cameras. Combined with a wider 1.7 aperture lens on the S7 cameras, that means you’re collecting significantly more light than before, which should result in sharper, less noisy low-light photos.

The S7 rear cameras also have a feature called dual-pixel technology, which has each photo pixel serving double duty. Every single pixel can simultaneously collect light while also capturing focus information. The S7s should be able to focus on an subject 2 to 3 times more quickly than other phones, including Apple’s iPhone 6s Plus.

For S6 Owners

It’s kind of a tough call to recommend the S7 line over the S6 phone. While the S7 phones will almost certainly be faster and more durable, many consumers may already have gotten past the need for microSD expansion. For owners of the regular S6 who may be considering the S7, it’ll probably be a pass.

The S7s, especially the standard model, don’t look that much better, or different, than the S6s, and the S7 screen resolution hasn’t gotten an increase. It really comes down to how much value you put in the S7’s improved camera, and if you really need the slightly bigger battery.

But for S6 or S6 Edge owners mulling a leap to the S7 Edge, the argument to upgrade is much more convincing. That’s because, with a massive 3,600 mAh battery and larger 5.5-inch display, the S7 delivers a big, dual-edged screen experience with all the bells and whistles of Samsung’s previous three flagships.

For S5 Owners and Older

But it’s a no-brainer to upgrade from the S5 to an S7. No one’s saying that you absolutely have to buy a new phone, but if you’re already considering upgrading from an S5, S4 or earlier Samsung phone, both the S7 and the S7 Edge are a great next step.

If you’re on a two-year contract, you probably have some upgrade credit coming your way, and going from an S5 to an S7 is like night and day. For people using even older models, let’s just say the S7 is on a completely different level. Anyone who skipped the S6 doesn’t even need to worry about losing features such as a microSD slot or water resistance.

The S7 has taken almost every single thing that was great about the S5 and turned it up to 11. If you’re finally ready to upgrade from your S5 or an older model, go forward and boldly embrace what will almost surely be the best phones Samsung has made yet.
