Call quality

With a great earpiece and three noise-canceling mics, Note 4 is the voice quality champ here.

The earpiece of the Note 4 sounds very clean and strong, with no audible distortions, and discernible voice timbres. Xperia Z3 exhibits an average call quality, as it is powerful enough to hear in noisy environments, but the voices coming through sound a tad muffled, and slightly distorted at the highest volumes. Both the Xperia Z3, and the Note 4's noise-canceling microphones, do a remarkable job at weeding out the ambient noises, and relaying are voice loud and clear to the other end. Samsung's handset now sports not the usual two, but three mics, allowing for a higher quality sound recording, and the voice calls with Samsung's phablet are no exception.


Outfitting the Note 4 with a 3220 mAh juicer, Samsung bragged that the phablet has a tad longer battery life than its predecessor, despite the Quad HD display, but hasn't posted official talk and standby times yet. Xperia Z3's 3100 mAh battery is cited as good for 16 hours of talk time in 3G mode, and the whopping 37 days on standby. Sony's phones are occupying the majority of the top spots in our battery benchmarks lately, and the Z3 is no exception, lasting almost nine and a half hours during our test, putting it at the top of current Android flagships. We will update with our Note 4 battery benchmark results as soon as we are done with the testing.

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
Samsung Galaxy Note 4
8h 43 min (Excellent)
Sony Xperia Z3
9h 29 min (Excellent)

minutes Lower is better
Samsung Galaxy Note 4
Sony Xperia Z3


Sony's OmniBalance design language is epitomized in the most stylish Xperia to date with the Z3, while the plasticky nature of Samsung's phablet line barely budges in the Note 4. Samsung's handset is bigger, but comes with a 20% larger, ultra high-res screen, which sports excellent color reproduction, while the Z3 display is very inaccurate in that department.

On the other hand, the more aesthetically pleasing and more compact Z3 is also waterproof, and houses stereo speakers at the front – features that are more useful than the heart rate and UV sensors, or the clunky fingerprint scanner that Samsung included in the Note 4.

Since the camera pictures and video quality are rather comparable between the two flagships, there aren't true advantages of the Note 4's bombastic spec sheet before the Z3, too, despite the higher chipset speed and pixel density on paper.

When it comes to multitasking, productivity and media consumption, though, the Note 4 is the undisputed king, with its large ultra high-res display, the extra stylus input, and the split-screen functionality. If you don't need that extra input, though, you will certainly appreciate the Z3's record battery life for the category, and the nicer feeling it leaves in the palm, pocket, and in the eye of the beholder.

Design, Battery life, UI - Z3 wins Camera, Screen - Note 4 wins.

Camera? "Somewhat surprisingly, Sony's digital image stabilization, called SteadyShot, performs almost as well as the mechanical OIS system in the Note 4 when it comes to keeping the footage fluid and steady regardless of the hand tremor."

If you see these 3 videos, there is a possibility that Z3 video stabilization is even better than the Note 4. As far as i know there are only 4 phones that have the most stable video stabilization Z2, 925, Z3 and Z3C.

lol...Not true at all 1st Link: The guy clearly says Note 4 has much better stabilization then iPhone's digital stabilization 2nd Link: Here we established that both the iPhone have negligible difference inspite of OIS and digital stabilization. 3rd Link: This proves Z3 has better OIS then iPhone. In short, those links you posted says nothing about Z3 being better then Note 4. It just shows iPhone's implementation of OIS is worst amongst Z3 and Note 4. Don't jump to conclusions so fast. Wait for the reviews from an authentic source.

Lol.. just watch the video and use your eyes there is more shake in Note 4 video and in the comment section many people dissagree with him because their eyes is saying the truth. Until this day i never seen any phones that has more stable video satbilization than Z3 the only phones that come close is 925.

'Until this day i never seen any phones that has more stable video satbilization than Z3' - Are you jumping to conclusions without trying the Note 4 ?!?! are full of bias my friend. BTW, I scrolled through comment section and found only 1 comment saying that. Rest agree Note 4 being much better. If what you're saying was true then the video would have much more dislikes.

No i'm not and if don't believe me just get the Z3 (you can, borrow or get to places where you can do a hands on) compare it with any phones that available that you think has better image stabilization and put extreme shake to see the different. Only one are you sure? How about Yudi Hilmawan, Ashwin R, Alex Papas, waqhbbb, Fastdounut BF, Daniel Orozco and MCButzi. Most of them is talking about overall performance not stabilization. Try to look carefully at the time he was walking around yoi can see the Note 4 video is more shaky than iPhone.

Dude clearly you have got yourself a Z3 and you'd do anything to justify your purchase. Since you might have to live with the 2nd best phone on the First, you said look at the comment section and now you are saying look at the video. Nothing you say is either agreed in the comment section or by the reviewer.

I agree with you. Z3 really does well with its steady shot.

Of course the camera for Z3 is better

lol.....wait for some reliable review. A channel with 200 subs can't be the most reliable source of info. Also, who knows if he actually even used both those phones. The number of dislikes in the video is another of sign of the credibility of the video.

Go check gsmarena compare tools and compare both note 4 and Z3. Note 4's camera is simply not as good as Z3's camera

strangely the note beats z3 in battery on other sites..

you say the z3 wins in battery life, but it lasts 46 more minutes and takes 140 more minutes to charge. if the person with the note 4 has an extra battery than they dont even have to wait for the phone to charge.

Design - subjective. UI - subj. Battery Life, ip68 certification - Z3 Camera, Screen, multitasking, resale value - Note 4 wins.

Equally great phones. The best in the market without a doubt.

Note 4 all the way. The true multitasking king.

Good job "Actually, the two chipsets are pretty similar in terms of performance, save for the improved graphics and video streaming part in the 805, so we wouldn't complain too much. The Xperia UI is lighter than TouchWiz, yet we noticed some gaps in transitions and redrawing while flicking the interface around – nothing to write home about, though."

Let me know when the Z3 is capable of multitasking like the Note 4. Wait, that's too much. Note 3.

Wait for Android L then let's see what you're bashing about. But I can't deny, I love the design of Note 4.
