Samsung Galaxy S6 Edge vs Sony Xperia Z5:Who is the King?

Samsung Galaxy S6 Edge

                                                                                                                                                                 This is a first for an AMOLED smartphone, and dramatically boosts screen clarity when you're outdoors. Colours look punchy and I had no trouble using it in direct sunlight.The Samsung Galaxy S6 Edge's wraparound screen transforms an already great phone into Samsung's best-looking handset. Ever. The QHD display complements the sweeping, curving design by giving you something visually stunning to look at. It's not a huge step forward from the full HD panel on the Galaxy S5, but it looks great.                    For a long time now Samsung has used Qualcomm Snapdragon processors in its flagships, at least in the West. In Asia it's been using its own-brand Exynos processors, which it's now opted to put in the Galaxy S6 and S6 Edge. And it looks like the right decision.

The Exynos is a 64-bit processor, so some 64-bit compatible apps should see a modest performance boost. More importantly, and just like the 810, it uses ARM’s big.LITTLE configuration. This allows a ‘big’ quad-core CPU (2.1GHz) to be paired with a ‘little’, low-power quad-core (1.5GHz). Smaller tasks like browsing the web and listening to music use the little quad, which uses less juice. Intensive tasks, like 3D gaming, use the big quad.

Even in power saving mode, the S6 Edge has a higher Geekbench 3 score than the HTC One M9 running at full speed. When it comes to 3DMark Ice Storm Unlimited test – a test that focuses on gaming performance – full power results are a lot closer, but even here the S6 Edge comes out on top.                                       What makes the Exynos 7420 special is that it uses a 14nm manufacturing process, like the latest Intel chips, that puts it ahead of the 20nm process used by Qualcomm on the Snapdragon 810. In layman’s terms, smaller manufacturing processes provide benefits to processing speeds and help reduce the use of battery power.

Not only is the Exynos 7420 super-fast, it also seems to run a lot cooler than the Snapdragon 810 on the HTC One M9 and LG G Flex 2. Even during a prolonged gaming session the Edge remains cool to touch, although battery drain rises significantly.

Gaming performance is top-notch with intensive games like Riptide 2 running like a dream. We didn’t experience a single dropped frame or stutter. The S6 Edge is a real powerhouse thanks to that beast of a processor. Samsung made the right move dropping Qualcomm’s effort.

but,That supercool design comes with a big price tag, and the screen doesn't deliver any real killer apps. Like the regular S6, the Edge doesn't support swappable batteries or expandable storage. The lack of expandable storage isn't a huge issue as the S6 Edge comes in 32GB, 64GB and 128GB flavors with the added bonus of 100GB of free OneDrive cloud storage - but battery life isn't up to standard. You'll struggle to see out a whole day with moderate usage, and that's a real shame. If you're a heavy user you'll be dashing for a charger mid-afternoon.

THE BOTTOM LINEThe Samsung Galaxy S6 Edge is one of those phones that sets a line in the sand for smartphones. It makes curved edges viable, offering them in a phone that doesn't look bonkers just for the sake of it. Samsung's striking, high-end Galaxy S6 Edge has the beauty, brains and brawn to take down the iPhone 6 and all the Android competition.                                                                                                     Key Features: 5.1-inch 1440 x 2560-resolution screen; Octa-core Exynos 7420 chipset; 2,550mAh non-removable battery; 3GB RAM; Wireless charging; Samsung Pay mobile payments; Android 5.0 L with TouchWiz

Color balance and accuracy, on the other hand, are areas where Sony should have tried a bit harder. The screen has a significant blue tint, taking some of the life away from images. It's not too bad, though, plus Sony is kind enough to let us adjust display color balance from the settings, meaning there's a way to get a more natural-toned image. Sony has to be congratulated for not playing the specs game and sticking with this resolution, because in no way is the Xperia Z5's screen harder to read, in comparison to the 1440 x 2560 screens out there. Sony needed to fix up the design of its Xperia Z series and there have been some big changes this time. It's still angular and glass-backed, but this time it's a frosted material instead of the clear glass we've seen on every iteration since the Xperia Z1.                                                                                                                                              A lot of the problems that plagued the Xperia Z3+ stemmed from Sony's choice of components. It was powered by Qualcomm’s Snapdragon 810, a chip that notoriously ran hot. So, it might seem odd to layman that, on the surface, the Xperia Z5 looks to be using the exact same chip.

But the 810 in the Xperia Z5 is a slightly upgraded version that supposedly solves the overheating problems. From my time with the Xperia Z5 I'm not convinced this is the case.

During bouts of gaming, even with titles that I don’t class as graphically intense, the phone gets hot below the camera. The heating issue gets worse when I fire up Asphalt 8 or Lara Croft Go. I wouldn’t be as fussed if it was only a minor temperature hike, but the Z5 got hot to the point I hat to move by fingers on several occsaions. The phone even gets hot when playing Spotify, which is odd.

The other major problem with the Xperia Z3+ was that its 4K recording was basically unusable. Capturing footage for longer than a few minutes caused the device to spew up a worrying overheating message and then crash. Thankfully, this problem seems to have been fixed on the Z5.

As a test, I left the camera recording a 4K video for half an hour. Aside from eating though almost half of my available storage, it didn’t crash or make the phone hot. Discounting the gaming bits I mentioned earlier, performance and stability on the Z5 are great. Switching through apps is fast, Chrome never feels sluggish and lag is non-existent. It’s a great performer.

But, for a flagship device costing £539, packing a high-power processor and 3GB RAM, I expect this.

The powerful chip produces impressive benchmarking scores too. With a 4,720 result on the multi-core GeekBench 3 test it outmuscles the LG G4 (3,260) and HTC One M9 (3,952), but just falls short of toppling Samsung’s Galaxy S6 Edge+ (5,014). On AnTuTu, it scores 53,155, putting it above the Nexus 6 (51,855) and Moto X Style (51,350), but below the iPhone 6S (59,069).

To be completely honest, I’d still have preferred Sony to go with the Snapdragon 808. The small losses in performance are easily made up for by the better heat control.

You get 32GB of onboard storage, though this can be supplemented by a microSD card. These cards are about to get a whole lot more useful in Marshmallow, as the OS will let you use them for proper system storage.

The dual front-facing speakers are well positioned, but they fall into many of the same traps as other phones. Volume is loud enough, but audio is tinny and lacks any sort of oomph. It’s fine for YouTube, but not really for music.

But,The Xperia Z5 Premium hype seems to have done that to some degree, but 4K is still an issue when you realise the battery life isn't perfected, and you will need to shell out quite a bit of extra money to get it.Only minor updates from its predecessor means it lacks the excitement of its rivals. Its waterproofing no longer allows for full submersion, meaning it can't be used for underwater photography.

THE BOTTOM LINE The Z5 isn't as perfect as it should be, but it does have all the right parts.Even with strong specs befitting a high-end phone, the Sony Xperia Z5 adds little over its predecessor to make it an exciting option over rivals like the Samsung Galaxy S6 Edge.
