Call quality

You'd think that call quality would not have been overlooked on a top-tier smartphone like the Sony Xperia Z2, but in reality, what we heard did not meet our high expectations. The earpiece is okay. Sound coming out of it is definitely loud enough, but average in terms of quality with sharp “S” and “Sh” tones. Loudness was sufficient on the other side of the line, but the digitizing of the sound is easy to detect.

Phone calls made with the HTC One (M8), on the other hand, sound excellent on both sides. The earpiece is loud and produces no crackling even at the highest volume setting. Its microphones capture audio clearly without much background noise disturbing the conversation.


Don't let the slim profile of the Sony Xperia Z2 fool you. Inside it is tucked a beefy, 3200 mAh battery rated at 19 hours of talk time on 3G or 30.8 days on stand-by. Music and video playback times are said to be 120 hours and 10 hours respectively, according to data provided by the manufacturer. Of course, the actual time between charges depends heavily on what the phone is being used for and your mileage may vary from these figures. But if used with moderation, the Xperia Z2 should have no problems lasting a couple of days on a single charge. We must mention that Sony has baked its Stamina mode into the phone's software. When enabled, it may significantly extend the handset's stand-by time by turning unused radios and features off when they aren't needed.

The HTC One (M8) has been equipped with a smaller, 2600 mAh battery, although the difference in capacity shouldn't worry you much. According to the manufacturer, that should suffice for up to 20 hours of 3G talk time, and stand-by time is quoted as 20.7 days. In addition, running our custom battery benchmark on the handset produced a result of 7 hours and 12 minutes, which is excellent for the M8's class. Having this in mind, we're confident that if you're not pushing it too much, you'll squeeze a couple of days' worth of usage out of the HTC One (M8) without reaching for a charger. And let's not forget to mention the handset's extreme power saving mode. Turning it on will shut down all of the phone's non-essential features, but may extend its usage time dramatically.

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.

Price-wise, the Sony Xperia Z2 and the HTC One (M8) rank among the most expensive smartphones money can buy right now, right along with other flagships like the Samsung Galaxy S5 and the iPhone 5s. But they're worth their price, given all the great features that both have to offer. Which one of the two you should pick, however, depends on your needs and taste.

Both phones excel in the design department – you'll be drawing the eyes of people nearby upon taking either out of your pocket. We'd say that the HTC One (M8) fits a bit better in the palm, but the Z2 is still okay as large as it is, not to mention that it compensates for its size with a slightly larger screen and a water-resistant construction. And speaking of screens, the 5-incher on the HTC One (M8) is indeed an eye-pleasing one, and with more accurately represented colors compared to the 5.2-inch panel on the Z2. The latter has the advantage of being a tad larger and with better-represented whites, but its pumped up colors aren't as accurate.

Then there's the performance of the two phones. Even though both pack the same silicon under their hoods, the HTC One (M8) feels slightly snappier, and we're guessing that the light-weight Sense UI has something to do with that. The Sony Xperia Z2 might feel slightly laggy if its home screens are too packed, but when it comes to, let's say, playing heavy games, Sony's flagship is in the same premier league together with the One (M8).

As for their UIs, Sense 6.0 on the HTC One (M8) is well-polished and very consistent. It is, without a doubt, one of the best custom interfaces that you might come across on an Android device. Plus, heavy social network users would probably be happy with BlinkFeed combining all their feeds in one single stream. Sony's user interface, on the other hand, isn't as radically different from stock Android, but it does add a number of handy modifications, including its Small Apps and its various options for personalization.

And when it comes to taking photos and videos, the Sony Xperia Z2 is the phone that has the upper hand thanks to its splendid 20.7MP camera. The Duo 4MP UltraPixel camera on the HTC One (M8) isn't bad, but it doesn't meet the expectations one would have for a top-of-the-line smartphone.

Z2 looks pretty cheap and not classy. The white trim ruins it.

have you ever seen one in personal? :) xperia z I agree it's not classy, but not looking so cheap also, but hell, ugly. It looks like a brick and u can bitch slap anybody using that phone, but z1 and z2, really looks premium, and eye catcher... i love z1 compact, because i have small hands, and i don't want to use 2 hands for a phone, for multi-tasking purposes. plastic yes, but it doesn't look cheap, it's beautifully crafted really well made, and very comfortable to grip and browse with your thumb only... :)

Ultimately it comes down to aesthetics for me because both phones are truly beasts at what they do. I'd prefer thee HTC One simply because I'm a huge HTC One fanboy. The Sony Phone is utter perfection though. I just wish the back had like this shattered look to it so when you drop it and it actually shatters, you can't tell.

So, as per yr conclusions general score is 4-1 in favor of m8. But the z2 has a higher rating in the individual review. Hah ?!

Straight edgeNexus, if you dont get my point, please don't TROLL. I was only trying to make Nick T confess. It is very clear from the comparison that he prefers the M8.

HTC one M8 is a near perfect phone, great design, great specs overall, but only let down by its camera. But had it has a 1/2.3" 8MP ultrapixel sensor, then it is perfect..

It's not all about MP's, but don't even think about printing a photo from the M8 to anything like a 4x6 or 5x8 because it's going to look terrible. I rarely ever do this, but when I do I want a alright pic, not crap. If I had to choose I would go with the Sony, but why not just wait for the LG G3 instead?

at least all flagships released this year can use sandisk's 128GB sd card. that's been tested and proved on some youtube video.

Sony has good UI but it should be smooth not laggy... they should focus on optimizing it. I'm using Sony phones from old SE times and though I'm entirely in love with Z2's display I'm thinking of either getting a lumia 930 or oneplus one as my next phone.

Battery life the Z2 kills the M8 and S5 those two respectively do 71hrs and 72 but the Z2 manages 89hrs it's on Gsmarena, but get this that's without any power saving enabled.

I love both actually. I prefer the looks and design of the z2 (I like square phones with sharp corners) but like the UI of the m8...
