Sony Xperia Z5 The Xperia Z5 has a very reliable battery and the addition of Quick Charge 2.0 will allow you to top off the battery quickly for those days when you need a bit more oomph to make it through your day.The Sony Xperia Z5 looks good, has plenty of power, its camera can take some great snaps and it won't die when you spill your drink on it.5.2 inches, 1080 x 1920 pixels, IPS LCD... 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.
VS Samsung Galaxy S6's The new super-skinny build does mean that this Samsung gets very warm in use, however. Actually, not warm, it gets plain hot. Finger-burning hot. This is something that's becoming more and more common with today's increasingly thin smartphones, particularly those that have metal bodies. But I'm pleased to report that even when it's got a fever on performance doesn't appear to be affected. The upscale Samsung Galaxy S6's smooth glass-and-matte-metal body, improved fingerprint reader, and convenient new camera shortcut key make the phone a stunner. Samsung's decluttered take on Android 5.0 brings the beauty inside, too.
BUT,Longtime fans will bristle at the Galaxy S6's nonremovable battery and absent expandable storage. The phone has an intensely reflective backing and looks embarrassingly like the iPhone 6. Battery life, while good, falls short of last year's Galaxy.
THE BOTTOM LINE Worldly looks and top-notch specs make the impressive, metal Samsung Galaxy S6 the Android phone to beat for 2015.
Octa-core Exynos 7420 big.LITTLE Processor; Mali T760 GPU; 3GB RAM
The Galaxy S6 runs Android 5.0 Lollipop integrated with a newly streamlined version of TouchWiz and it’s incredibly snappy to use. One of the best features is the multi-window functionality – I used it frequently.
Multi-window lets you open and use two apps simultaneously by holding down the option button or dragging from the top left corner of the screen. It’s great for writing an email while checking details online, or sharing posts from social media while talking about them with a friend on WhatsApp, for example.
Overall, the streamlined look and feel of the TouchWiz is a winner. We did experience a couple of instances where downloaded and native applications would randomly stop working, but we imagine this will be smoothed out fairly easily with updates.
TouchWiz gets a huge helping hand by the fact this is the most powerful smartphone on the market right now. Only the HTC One M9, with its Qualcomm Snapdragon 810 processor, gets close to matching its performance.
The credit goes to the 64-bit Samsung Exynos 7420 octa-core processor and 3GB RAM – it’s the first time Samsung has used this chip in a phone. It seems that switching away from Qualcomm’s top-end Snapdragon processor in its flagship phone has paid off handsomely.
The Exynos 7420 processor has an advantage over the powerful Snapdragon 810 processor used by the HTC One M9 because the chip is smaller and more energy efficient. You can read the software and performance sections of our Samsung Galaxy S6 Edge review for a more detailed breakdown of how it compares to the competition, but needless to say the S6 impresses.
One of the best demonstrations of the Galaxy S6’s power is how smoothly it handles graphically intensive games like Real Racing 3 or Asphalt 8. There are no dropped frames whatsoever and the games are rendered better than we’ve seen on any other phone. Battery life
Battery life on the Samsung Galaxy S6. Now we get to the real issue of this phone. It's not good enough, and that's hugely frustrating.
Let me put this into context: it's as good as the HTC One M9 and iPhone 6 in terms of being able to last just about through the day. Given that last year we were seeing phones that could easily make it to bed time without running out of juice, it's maddening that Samsung, like others, has gone backwards here.
The reason is simple: the battery pack in the new S6 is smaller than last year, 2550mAh compared to 2800mAh. The reduction is there solely so Samsung could make a slimmer phone, focusing on design over functionality. And unlike previous years, the battery can no longer be removed, taking away one of the big things fans loved about the phones.
