Galaxy S8 vs Xperia XZ Premium: both excellent, but only one will make you wish you'd bought the other


Last year, I switched my Sony Xperia Z2 for a Samsung Galaxy S7. Up until that point, I'd never even considered getting a smartphone that ran TouchWiz. With the update to Android Nougat, Samsung has proven that it's not only capable of delivering great hardware but it can do really good software too. Today, I use a Galaxy S8, and if I compare it to the Xperia XZ Premium, there’s no way I’d go back to using a Sony device.
Over the years, Sony has been slowly and steadily cleaning up its software and making it look more like pure Android. Samsung, on the other hand, has been loyal to TouchWiz from the beginning. However, with its new UX Experience, it’s redesigned the whole system. When you unlock the screen on the Xperia UI, the first thing you see is the app drawer. On the Galaxy S8, you clearly don´t see it since, like the Pixel Launcher, Samsung opted to go with gestures to access apps.

This is a perfect example of the impression I have of each model: one is stuck in the past, while the other is looking to the future. The Xperia UI reminds me a lot of the Nexus line, which will stop receiving new update support in September of this year, whereas the Galaxy S8 software brings different features from Pixel. Are you guys starting to see where I’m headed with this?

The European and some other national Galaxy S8 and S8+ models are packed with an Exynos 8895 processor, which comes with 10nm technology developed by Samsung. However, the US version comes equipped with a Qualcomm Snapdragon 835 CPU, which is also 10nm. It has four cores that clock in at 2.45GHz and the other four at 1.9GHz. Sony also opted for this latter processor in the XZ Premium. So, in other words, the performance of both devices is very similar. So much so that in our speed test, which was based on daily use, both devices finished the actions at the exact same time.
The XZ Premium did get a higher grade on the most detailed benchmark though. Using the PC Mark Work 2.0, Sony's device got 6338 points, while Samsung’s earned 5094 points. Obviously, basing everything on benchmarks isn’t the same as actual daily use of a device. However, I should mention that if you put the devices side-by-side and open an app at the same time, the Xperia XZ Premium does respond a few milliseconds more quickly.

The graphics on both devices are top of the line, and neither loses any details on images. However, the Galaxy S8 does have Game Launcher, which improves gaming experience with screen and notification locking features, while nicely collecting all your games into one place. But remember, Sony makes PlayStation, and there’s an undeniable integration between the XZ Premium and the gaming console. I especially like being able to continue playing on my phone.

Now, there’s one thing that Sony will never leave in the hands of another manufacturer: sound quality. In this respect, the XZ Premium earns the title. The stereo sound for both gaming and videos is everything you could ever want on a smartphone.
Things get even better when you use the XZ Premium with wireless accessories, like speakers or headphones. Since Sony supports LDAC technology, there isn’t any data lost on sound quality.
Compared to the XZ Premium, the sound quality on the Galaxy S8 is just ok. The device offers UHQ sound quality when using headphones or Bluetooth speakers. But a feature that Galaxy S8 comes out ahead of the Xperia XZ Premium in is Bluetooth 5.0. Don't get me wrong, the XZ Premium has the same version, however, it doesn't allow the user to take full advantage of this standard like Samsung does at the moment.
In other words, the dual audio feature, which allows you to simultaneously connect two Bluetooth speakers or even two headphones to a device, is only offered on the Galaxy S8 and Galaxy S8+ at the moment. However, Sony may offer the same function through a software update in the future.

As audio always comes hand-in-hand with images, it's a heated battle over screen quality between these two devices. On the one hand, we have the Super AMOLED display, with curved edges, HDR and the new 18:9.5 ratio; on the other hand, a lovely example of an LCD screen, with excellent resolution, HDR and a 16:9 ratio. Both manufacturers have done a fantastic job in this area, and either one of these devices will give you one of the best displays you can find on the market today.
However, to reiterate my point, Samsung shows that it’s thinking about the future while Sony is keeping things conservative. This isn’t necessarily bad though. While S8 users are prepared to receive content in a new ratio, as it’s just starting to pick up some momentum, they’ll have to deal with videos with different margins and games with hidden menus due to the image adapting to the screen. No one ever said being an innovator was easy.
Even the XZ Premium has to go through content restrictions for your 4K screen. Currently, not many services support screens with such a high resolution, such as YouTube, Netflix and also Amazon Prime.

With the quality of the display and audio, using the XZ Premium for games and watching videos on Netflix or YouTube is incredible. It’s exceptionally comfortable to hold since it has such wide edges, however, considering that the Galaxy S8 uses 83.6% of the front display, when you put them side by side, it’s like putting Prince Charming next to Shrek.
Yes, I realize that the Galaxy S8 isn’t the most comfortable device to hold to watch an entire episode of Stranger Things since there aren’t any side borders and the ones on the top and bottom are basically non-existent. With a bit of practice though, I discovered how to hold the device in my hands without it getting uncomfortable.

The XZ Premium is swimming against the current; it’s massive, square and conservative. To give you a clearer idea, it can stand up on one edge without having to support it. And no, this isn’t an extra feature! Regarding the design, Sony forgot that they’d put the word “Premium” in the name.

It could all be justified with battery life, couldn’t it? Unfortunately, no. The difference between the two devices is just 230mAh more for Sony’s smartphone, but remember that the display is 4K. The hardware on Samsung’s device consumes a lot of energy as well. Although Performance mode does offer four different power settings and it offers anywhere from 6 to 12 hours of battery life, while the XZ Premium lasts about 7 (according to the battery benchmark on PC Mark).
Both manufacturers offer two energy saving modes and rapid charging. Unfortunately for Sony, only the Galaxy S8 has wireless charging.

Finally, let us discuss the camera. Sony invested a lot into the camera specs and features on the XZ Premium, whereas Samsung pretty much copied the good aspects from its last generation and made some small tweaks to the software to improve image capture. In the end, the camera on the Galaxy S8 is one of the best on the market. This was confirmed in our camera blind test, where the Galaxy S8 finished right behind the Google Pixel. The same can’t be said for the XZ Premium though, which found itself nearer the bottom on the list.

The camera on the XZ Premium has an optical image stabilizer and a Bionz image processor in addition to an Exmor RS 3-layer stacked sensor with 19MP and large pixels. These components let you use super slow motion, which generates videos at 960 fps, 32x slower than normal.
This feature is really cool, but in your day-to-day life, you’ll need a camera that's consistent, with image quality in low-light settings and quick on the trigger. That’s why I’d go with the camera on the Galaxy S8. Take a look below to compare the test galleries of each model:

Without a doubt, both models are good. It just so happens that in my opinion, the Galaxy S8 is better. With hardware performance similar to that of the XZ Premium, the Galaxy S8 stands out on most things. It won’t be considered old next year, and it has solid software options like system backup, different biometric and security options, and software that works well with the hardware to give you more battery life.
Today, before finishing this comparison, I asked the editors at AndroidPIT which of the devices they’d buy if they’d just seen them for the first time. Of the 15 people in the room whom I asked, only one person chose the XZ Premium.
What do you guys think? Let us know your thoughts in the comments below.
This is why "tech expert" is such a laughable term. You spend every day living in your own little bubble, getting sent your free phones, you do your little straw poll to confirm "oh yes, I'm definitely right about this, yes" - you even spend an entire article banging on about how antiquated the Sony is....then you ask ACTUAL phone users, and discover your 'expertise' is pretty much worthless.
I will choose Sony Xperia XZ premium because you can hold it securely without fearing of accidental drop. S8 is just good if you are not holding the phone like a mini TV. You need a mobile phone holder like a small tripod.
Sony allows you to hide the app drawer and use the swipe up gesture; you have a choice, something increasingly rare in the Android world...
Sony makes high quality and durable phones. Samsung makes glossy displays, nothing more.
I chose xzp. For me was the best option because I put first in line audio quality and sony attention to detail. I own this phone for 5 months and I haven't anything to complain, now it runs android 8.
I don't understand why it is so overlooked by the tech professionals. Probably sony don't pay them like samy or apple. I hope sony keep the good work.
I am using Samsung S8, This is the best phone in my life. I am too much happy.
The design of the Galaxy S8 is very good, but I prefer XZ Premium's. Also, you must be kidding about the camera, XZ's is the best in the market right now, S8's is good, but xzp is far better
Samsung uses sensor from Sony...
But Sony makes the worst picture...... poor implementation
Learn from Samsung
Sony phone camera are just bad. You can’t change it, the bitter truth.
Hi all,
i'm using z3 compact itz good but service is not good from sony, i have display problem scene i bought the phone. this is a 3rd time i'm submitting my phone and service center call me after 45 days with overall estimate of rs 9,950Rs.. and price of same model on amazon is 12,000 rs.. i love sony product but its not for long time its about 2 or 3 years after that its not useful. sony don't have a resell value. we are not invest 50k or 60k+ every 2 year in smartphone.... sony must be introduce replacement policy. in xz-premium must be secure fingerprint under gorilla glass, after scratch on it its not working properly, and one another thing witch is sony always use plastic body... its not good...
My Samsung 7'' tablet from circa 2011 still stuck on android 2.3. Any updates are at my own risk... Never ever Samsung again!
S8 android 7.0 (it will probably lag further as time moves on, stuck in the past!) XZ android 7.1.1
Sorry, but the XZ Premium has one of the best cameras I've ever had. Especially in video modus it's amazing sharp and has very fast autofocus and amazing depth of field. I don't know how you tested the camera... Also the battery it's enough for two days without stamina and the 4k display doesn't take effect on battery life. I also made a photo of a car driving at 180 km/h and even the spinning wheels where exactly taken with all details, so that you thought they standing still.
I use a Xperia from years, the XZ premium has a long battery time, but the camera quality is low
Maybe you don't know how to use
You are right bro
Bro, I think you haven’t used anything other than Sony. Even cheap Chinese phones have better cameras than Xperia phones
To be honest, while i have long been a Note user, I am thinking to buy an XZ Premium. I am not too sold on the new screen ratio and Samsung policy in terms of updates is terrible. And having seen both displays next to each other I must say is the first time a Sony device left me so positively impressed.
Ive had the xzpremium for a few weeks now after upgrading from Z5 initially thought it wasn't worth it but now it is and is definitely worth it, don't think there's a better phone at this time! ok its a plain design but who cares.
Not a sony fanboy xzpremium is overpriced but so is the s8 ive had a xzpremium for two weeks and i know someone who has a s8 plus and the xzpremium is by far the fastest and people and reviews keep saying the s8 has a better camera i can definitely say it isn't the sony camera beats it in all but extremely low light conditions and gives a lot better colour rendition so to me its a better than the s8 maybe not as good a looker but as with all phones you need a case for protection so it doesn't really matter about the look as its covered.
I think they're both overblown and overpriced. They're more involved in trying to be my BRANDED phone rather than being my tool. I want my phone to get out of the way to the extent possible and facilitate my life and necessary apps. Brand, gimmicks, skins and such are not why I have a particular phone. Brand based apps tied to a particular skin has never been what I use for any of my functions. I need to have the same apps everywhere and to be hardware/skin agnostic.
The skin and bloatware apps are really antithetical to the principles of good hardware and software design and implementation. Yes, there are good arguments for camera specific abilities in some cases, but mostly I use aftermarket camera apps as well so I always know where to find the right feature.
I would prefer to see optimizations for battery efficiency; antenna efficiency; universal band support; decouple the SD card from the Sim tray so I don't have to reboot to swap cards, just unmount; More open OS and software so instead of locking me out of bootloaders, root and ROM and some apps, let me actually be administrator on my phone. Implement the full spec for USB C so I have video out and OTG support and all that.
S8 all day. A bunch of sony fan boys. I have a s8 & its a great phone. If you go with what fans say on this here, you'll find yourself not wanting a lot of phones. Get what you like & not what this site say. Peace & Love ✌?
I'll take the s8 but the xz premium is a very good phone. I can honestly say either one would satisfy me. This is the best Sony phone to date!
if I had to choose..
Sony..
yea it's looking a bit dated next to S8 and G6, but it's still very much an impressive flagship, with premium build quality, specs and durability.
and still a superior multi media UX thanks to front facing audio..
I like Sony's omnibalance design, for the future all they need to do is increase screen to body ratio and keep front speakers.
SONY RULEZ!!!!!!! IM GONNA PICK UP MY PRE-ORDERED XPERIA XZ PREMIUM TODAY
These phones look pretty good, I personally have an Xperia z5. I'm defiantly not going to upgrade because there would be no need to do so. It's the same phone over and over, Samsung has been tying, but for me it doesn't have that edge™. The Xperia xz is the same as the z5 in a way. If these phones were much cheaper and had the same hardware (or if Sony and Samsung came together) that would be pretty good indeed.
P.s. Can every one stop saying the Xperia has ois (a little mistake in the review)
S8 looks great but this time around Sony really nailed it. I've checked a bunch of videos on YouTube and yes, XZ Premium is the fastest in launching apps on the market as of now. It beats iPhone 7, Galaxy S8, and (to my surprise) even OnePlus 5!
Moreover that super slo-mo intrigues sports people like me...
The S8 is undoubtedly cool and cooler than the relatively old-fashion Sony, but I'd pick the Sony.
Samsung's software update policy is much worse compared to Sony, who's actually quite good at releasing new Android versions for its flagships, and supports them for a long time. The X1 went to Android 6.0, and you didn't have to wait two years to get it - how does Samsung fare for old flagships?
Samsung's duplication of apps (assistant, email, browser, calendar etc) is something I absolutely do not want on my phone. I generally find them of poor quality, they cannot be uninstalled or in some cases fully disabled (that Bixby button I think stays in the camera app no matter what). It's a funny case of more is less here, and it's a deal breaker for me.
I had a Samsung, still works fine as a backup phone, but the software, update and support experience have fully convinced me to never buy Samsung again, no matter how cool the device looks. It's just not worth the aggravation and in my opinion, poor overall ownership experience.
For me it has to be the Sony XZ premium, it beats my partners s8 hands down, taken the same pics and Sony was better, watched films and the Sony screen is amazing as is the sound, I really cannot fault the Sony, my partner uses my old Xperia X so she doesn't have to use the gs8. Everyone has their own opinion about phones, I have always had Sony even back to the days of Sony Ericsson cybershot, I did switch to Motorola for a while but that was well before phones got smart. Motorola are sneaking back up the rankings especially pushing the boundaries of attachments, but bringing my comment to a close Sony has always been associated with technological class and that is why they get my vote when it comes to outstanding brilliance.
As a Samsung galaxy S7 edge user, I would choose the Sony. I just hate the reflections on the curvature of the screen. Also, the Samsung is the only phone I have had that needed to be reset to factory default because of dramatic slowdowns. I never had this issue with Huawei p8, nexus 5, and various other brands. For me personally, I never will buy me a Samsung ever again.
Sony seem to be the only company that will not change the design of there phones, nearly every Sony phone looks the same, an the Bezels at the top and bottom take away so much screen usage,that's why there phones have to be so larger and wider than the others,Sony might have a good name with there cameras, but Samsung is getting a lot better,the audio on Sony phones as not been very good audio the time,why is smaller battery employed by Sony is not a very good selling point,when consumers want more phone usage
I chose the Sony Xperia XZ premium
I have no desire to ever own another Samsung device.
This article is spot on. I feel the same way. I don't think I can ever use a smartphone without TouchWiz anymore after switching to the Galaxy S7 (the flat one) last year. And this come from a person that hated TouchWiz not too long ago. It have all the things that I could ever want on a smartphone. Excellent battery life, clean and feature-pack UI (I think Samsung isn't credited enough for this. There are so many useful features on TouchWiz such as Ultra Power Saving Mode, Multi & Pop up windows mode and more), outstanding and consistent rear camera, sexy design, and above all, the breathtaking sAMOLED display. The only downside of my S7 is that it's too small. (should have bought the S7 edge. But hey, I bought my S7 for just $450 and that's good enough for me. hahaha)
I just really hope Sony fan won't come to diss you for your honest opinion article.
You should mention build quality all glass vs metal build. I will take the metal.
Since when did either of these two phones have an all metal build? Both of these phone have a metal and glass design.
you are right my mistake I though the Sonny still had a metal back. I will still take the flat display over curved, the curved display is just a gimmick.
Me too. I would rather pick a flat display (GS7) than a curved display (GS7 edge). But not because of usability or palm-rejection problems though, (been playing around with the GS7 edge and the GS8 and have no problem with it's curved display whatsoever). It's just that I'm a clumsy person, but don't like putting a protective case on my phone (lol). So, dropping a curved display phone would be a nightmare for me. hahaha. But I'm sure I'll be getting a curved display Galaxy in the future when my GS7 dies on me though.
My next will be the LG V20 since the V30 will copy the G6 and go all glass non removable battery. I have to have a removable battery to bad every body is jumping on the planed obsolescence wagon. My Note 4 still rocks luckily.
