Call quality


Not only are voices exquisitely loud and commanding with the HTC One (M8), but they’re also clear and noise-free for the most part – making it very easy to hear our callers in extremely noisy environments. Lucky for us, that’s also the case switching it to speakerphone mode, where its dual front-firing speakers deliver a potent mixture of power and clarity. Lastly, our callers also benefit by being greeted to voices that are robust and lively on their end of the line.

Although not really amazing, the Xperia Z1S also does a good job when it comes to sound quality during calls. Loudness is just enough, while voices tend to sound clear enough to be easy to comprehend. Naturally, there's a second mic on the Z1, which is used for noise-cancellation, so your callers should be able to make out what you're saying even if you happen to be in a noisy environment. On the other side of the line, callers are mostly pleased by what they hear. The loudspeaker is neither very powerful, nor high-quality. It'll do the job if you're in a quieter place, but forget about using it outside when it's noisy. The M8's BoomSound speaker will be better suited for this task.

Battery


The HTC One (M8) is equipped with a 2600 mAh battery, which doesn't seem as impressive as the Xperia Z1's 3000 mAh juice-pack. However, having run both handsets through our custom battery life test, we've discovered that the One (M8) can offer great longevity. It actually surpasses the Xperia Z1 in this respect, suggesting smarter power consumption on HTC's part.

When it comes to official battery ratings, HTC claims the One (M8) can last for up to 20 hours on 3G talk-time and 20.7 days in 3G stand-by. Meanwhile, the Sony Xperia Z1S is rated at 15 hours of 3G talk-time and 35.4 days in 3G stand-by. Naturally, your real-life results may vary greatly, depending on your usage patterns, but as a whole, we expect the HTC One (M8) to deliver the better battery life between the two.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

hours Higher is better
HTC One (M8)
7h 12 min (Good)
Sony Xperia Z1
4h 43 min (Poor)

Conclusion


There is no doubt that the HTC One (M8) is the better smartphone of the two... for the most part. The one area where the Xperia Z1S easily steals the show is the camera, as HTC's UltraPixel thing continues to lag behind the competition. That is not to say that the 4 MP shooter of the M8 is poor. No, it's actually pretty good for casual use, but if you want superior performance from your smartphone camera, then the 20.7 MP G Lens snapper of the Z1S will do a better job.

Aside from that, the One (M8) sports a newer chipset, better screen, nice front-facing speakers, and better battery life. In terms of exterior, well, both handsets are spectacular. The Z1S has the advantage of being water- and dust-resistant, but it's like the new One is the more likely phone to win a design award. Similarly, both handsets offer very nice and polished custom user interfaces, with that of the One being a notch fancier.

At the end of the day, the more advanced technology in the One (M8) allows it to bestow consumers with an overall better experience (except for the camera department). But we wouldn't have declared it a clear winner if it wasn't for the immense amount of work HTC has put in the design of this gorgeous smartphone.

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.

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
