Interface and Functionality

As both user experiences are very well designed, the One (M8)'s Sense UI differentiates itself by having a bit more character to it.

Running HTC Sense 6.0 on top of Android 4.4.2, the One (M8) brings a user interface that's in line with recent software design trends, being flatter and lighter, but this doesn't mean the HTC has abandoned its traditional UI style, which makes its software appear very polished and mature. In comparison, the Sony Xperia Z1S runs Sony's custom Android interface, which is also quite cool and modern, but overall, HTC's offering has a bit more character to it.

Both user interfaces are quite profound, as they customize almost every core OS application, such as contacts, messaging, calendar and others. Luckily, the two UIs offer strong alternatives to the stock applications, so users have no reason to feel bad about having an Android smartphone with a custom interface. After all, the customizations make the phones look and feel unique, and when you factor in that both are quite polished and free of any major issues, this do look pretty good on the software side for both.

Apart from their customized apps, Sense UI and Xperia UI offer some unique features to entice customers with. To start with, HTC's One (M8) sports the BlinkFeed news and social networking aggregator. The feature has gotten smarter in the M8, detecting what you're more interested in with a higher degree of success. Plus, it's now integrated with Fitbit, so if you're a fan of the service, then you have an additional reason to give BlinkFeed a try. Moving on to other unique aspects of the M8's UI, it's the new motion gestures that capture our attention. Instead of trying to create something fancy but gimmicky, HTC has actually come up with a few really useful gestures that we can see ourselves getting used to in the long run. We already mentioned double-tap-to-wake, which is used to wake the display up and view the lockscreen. However, you can also directly unlock your phone from an idle state by doing a swipe-up gesture. Conversely, swiping from the top edge of the screen will execute the voice-dialer.

Obviously, Sony has decided to put more effort in some other areas, such as camera and entertainment, as far as unique software features go. That is why we don't see the manufacturer put so much emphasis on the general user experience part of things. Still, we can mention things like Sony's small applications, which can be used to give your multitasking game an edge. Another cool option is the display color temperature setting, allowing you to tweak the colors of the screen to your own liking.

Processor and Memory

800 is a big, respectable number in the world of smartphone chipsets, but 801 is even bigger.

Geez, mobile silicon has been developing so fast that at the current time, getting a flagship phone with a chipset that's one or even two generations old will practically secure you all the horsepower you may need, in most usage scenarios. Indeed, we're in a situation where mobile software has failed to keep the same pace of advancement as hardware, which is why the fact that the One (M8)'s Snadpragon 801 SoC is slightly more powerful than the Z1S' Snapdragon 800 isn't really so important. Still, you'd never see us running away from the prospect of having a faster chipset, so yeah, the M8 sure is the more desirable option on the performance front.

Getting a bit more specific, the HTC One (M8) relies on four Krait 400 cores, each of which can be revved up to 2.3 GHz. Meanwhile, the Xperia Z1S' speed limiter is almost equally generous, as its four Krait 400 cores can reach 2.2 GHz, if need be. Being seemingly the same on paper, the Adreno 330 GPUs powering the two phones will no doubt guarantee superior graphics performance. However, in various scenarios, the one in the M8 should be able to perform up to 28% faster than its counterpart in the Z1S.

RAM is set to the healthy amount of 2 gigs on both devices, but there's a slight difference when it comes to their storage options. Namely, the HTC One (M8) comes in variants with 16 and 32 GB of internal storage, while the Sony Xperia Z1S is only available with 16 GB of storage space. Thankfully, both phones sport microSD slots, letting you insert memory cards in order to expand their storage.

I've held the Z1S and the first thing I noticed was the display is very poor. I'm hoping the Z2 is a big improvement.

Is HTC's duo camera is just used only for some eye catching effects??? No combining pictures for larger images??? It should have been 8MP UP this year at least . I would like to see a comparison of HTC M8's front camera with the rear. besides the camera M8 is pretty awesome. love the sense ui and fast auto focus.

The new HTC One should be pitted against the Z2 for a fair and exciting game, not its predecessor Z1/Z1s.

11. Amir1 unregistered

wrong. M8 is comparable to Z1. Z2 would smash it.

from what i've seen, only in the camera department

I'm sure they will once Sony releases it to the mainstream.

Right, can everyone agree now that a large battery rating doesn't mean a long battery life.

As i told htc fanboys m8 was going to fail in camera. Lol 4mp dont tell me MP dont matter. 4k recording needs atleast 8.3mp sensor.

15. engineer-1701d unregistered

do you have a $5000 tv with 4k viewing if not no reason and if you do then you should have a pro camera, it should have been a 8up but we dont know what it takes to make a 8up camera maybe they will release a 2nd phone later like note and the 8up will be on it samsung held the tech for its notes maybe htc is going to put 2 high end units out a year.

Why was my comment removed Ray S. ? Why even run a comment section if you guys only promote your views in comment section and simply remove the rest ? #growapair

20. g2a5b0e unregistered

I'm guessing your comment was removed because the S5 is irrelevant to this article.

Well, I wrote it as a joke and even mentioned 'jk' = Just kiddin' in the end. It was just to poke some fun as Samsung articles are full of praises of Z2 in the comment section. Also, my comment also consisted remarks about the phones in this article too. Irrespective of that, as long as I am not breaking any rules my comment shouldn't be just deleted without even mentioning the reason.

Actually, a lot of the M8 sample photos look better to me than the Z1s. I'm sure there's less detail if you zoom in, but zoomed out, they look perfectly fine.

14. papss unregistered

My m8 will be waiting at my house tonight when I get off.. I can't wait to put it thru its test and see what it does great at and what it doesn't.

16. engineer-1701d unregistered

did you see the water test it was in the sink under water for 2 hours no problems. they should market that and all the phones features.

17. papss unregistered

I have not seen that one.. I'll have to you tube it..

Take a look at this.... Samsung Galaxy S5 has the ‘best performing smartphone display’ DisplayMate compared the display on Samsung’s latest flagship to existing phones, and found it to have the best overall display, especially in color accuracy, brightness levels, viewing angles, and contrast. have the most accurate colors for any smartphone or tablet when Cinema Mode is activated, and it was also the brightest display ever tested by DisplayMate, having the ability to reach 698 nits of brightness

Why are they comparing these two? Not fair to Sony.

We all know Z1 is the winner here. Functionality durability technology . Oh wait m8 won coz of viewing angle. Who the hell watches video sideways? Oh wait the boom sound. Seems to me sound system of Sony is far more superior than any front facing speakers. They did these comparison just to emphasize how far is the difference between Htc and Sony. Sony>Htc.

I own both phones on my account. I don't agree that the M8 is a hands down winner. I definitely prefer the look and feel of the Z1s. The screen of the M8 is better but the screen on the Z1s is crisp and bright as long as you are looking at it straight on and not at an angle which is how we all use our phones 99% of the time. The speakers on both are fine. Yes the M8 is preferable but I would not use either phone to listen to anything like music without headphones. As far as battery life, in real life use they are equivalent. I never feel like these automated battery tests ever give true to life results. I would actually say that the Z1s give me better battery life if I gave an opinion based on gut use but the M8 definitely does not outlast the Z1s at the level this review implies. In either case it is a great thorough review. In my case the the camera and feel/ruggedness of the Z1s wins. on all other matters I would rate the phones as very equivalent without any clear winner that would sway my choice of phone. Steven
