Sony Xperia Z5 vs Xperia Z3: Should you upgrade?

Sony Xperia Z5 vs Xperia Z3: Should you upgrade?

Well, folks, it's official – Sony's flagship for 2015 is the Xperia Z5. Donning a slight facelift, a 64-bit processor, and a camera upgrade, the handset looks like it can go shoulder-to-shoulder with the rest of this year's top-shelf handsets. Still, the Xperia Z3 wasn't a bad handset in its own right, and did pack some serious hardware of its own. So has the latter grown obsolete in the last 12 months, and does the Z5 cover enough new ground to warrant an upgrade? Let's take a look!

Familiar design with slight touch-ups


You'd be forgiven if you find yourself confused when trying to distinguish between the Sony Xperia Z5 and the Xperia Z3. The two share very similar design cues, have the same dimensions 5.75 x 2.83 x 0.29 inches (146 x 72 x 7.3 mm), and house similar 5.2” displays on their fronts. The Z5 has received a slight facelift, however, which becomes apparent after a quick inspection.

The new Sony flagship still retains the metal-and-glass sandwich constriction, but this time around, its back panel bears a “frosted glass” finish, giving it a matte look and a less slippery feel. In comparison, the Z3's back is glossy, gets smudged by every touch that lands on it, and is very slippery, both in-hand and when laid on a surface. Additionally, the Xperia Z5's metal frame is slightly flattened across its sides, instead of the Z3's curved ends, making it slightly easier to hold. On the flipside, the place on the Z5's back, where the glass meets the metal, has a slight edge, which some may find a bit irritating.



Same old display


The Xperia Z5's display shares the same 5.2” diagonal size and same 1080 x 1920 resolution as the Z3. We did find it a lot less colder, however – back when the Xperia Z3 first arrived, it shocked us with a crazy amount of blues in its display. It seems like we are not the only ones who found this unpleasant, and Sony took appropriate action.

Color temperature aside, the Triluminus IPS LCD display is as sharp and crisp as it was before – Sony didn't jump the QHD bandwagon, but the screen on the Xperia Z5 still packs a pixel density of 424 PPI. Quite enough for a pleasant viewing experience.

User Interface


Owners of the Xperia Z3 who have updated their phones to the latest, Android 5.1 Lollipop-based Xperia UI will find the Z5 to be identical. Sony hits a balance between adding its own, proprietary looks to the operating system, without bogging Android down with too many features, apps, or processes, so it runs as snappy as we've come to expect. The Material Design ideology doesn't seem to be a favorite of the manufacturer, however. This may annoy some, but those of you who don't really like Google's “flat” interface ideas may want to seek refuge in Sony's camp.

Processor and memory


To stay relevant, Sony had to equip it's newest and greatest with a 64-bit processor. It chose the Qualcomm Snapdragon 810, which has stirred up some controversy ever since being in pre-production. Reports of overheating, throttling, and not much increase in performance, when compared to the Snapdragon 801 and 805, have plagued the SD 810's existence ever since Samsung chose to use its own chips inside the Galaxy S6. In the short time we had to play with the Xperia Z5, we couldn't confirm nor disprove any performance or temperature issues, however, so judgement here is still up in the air.

As far as RAM goes, both handsets retain the same generous amount – 3 GB. As for internal memory, the Xperia Z3 is sold in variants that have 16 GB of storage, but, so far, we are led to believe that the Z5 may come in 32 GB only.

So, all in all, the Z3's processor and RAM are still quite relevant here.

Fingerprint sensor


Of course, every flagship that wishes to stay in the game nowadays needs one of these. The fad, which started with the iPhone 5s and its Touch ID, has now spread across many of the Xperia Z5's Android-bearing competitors, and we understand that Sony had no choice but add their own version of a biometric scanner to the handset. In the case of the Z5, its combined with the power key, which is now much larger than the one on the Xperia Z3. So, if a fingerprint scanner is your thing, there is no competition here – the Xperia Z5 is the clear winner.

Conclusion


Sony's newest top-shelver may not look very different than its predecessor, but we certainly appreciate the small touch-ups, which help keep the already good-looking design feel fresh. The matte back is a welcome change for anyone who loves the feel of glass, but hates the fingerprint smudges and inherent slipperiness, the flatter sides are a welcome upgrade for comfort, and the discreetly etched Xperia logo on the side of the frame is a nice touch.

The camera upgrade is also an exciting bit, as we were slightly underwhelmed by the Z3's snapper, especially when compared to its relevant competitors. What Sony promised about the Z5's picture quality and under-the-hood features sounds promising, and we can't wait to put it through some extensive tests.

Hardware-wise, however, the phone doesn't seem to offer a great leap ahead. Sure, it brings the Xperia line to the 64-bit table, but this doesn't seem to be much of an issue just yet.

All in all, it's a mixed bag – if you are nearing your upgrade cycle and want to go with Sony again, the Xperia Z5 seems like a great device to get. But if you still have a relatively new Xperia Z3, we'd say you should hold on to it for the time being.

I'm definitely upgrading from my Z2 provided the battery life isn't poor.

I'm also upgrading from my Z2 if the battery proves to be good enough. It will either be the Z5 or the Z5 premium, not sure yet. Looking forward to the reviews!

You're talking about the S6 correct? Because both those devices have better screen to body ratio's than the S6.

Actually it doesn't. The S6 has a 70.7% of screen to body ratio, where as the Z5 has 69.6%. As for the Z5 Premium, it is 70.4% compared to the 75.9% of the Note 5.

Actually, it does. Do the calculation yourself, and you'll see than the Z5 Premium has a 71% screen to body ratio, whereas the Z5 has a 70.8% screen to body ratio. And guess what Maherk? PhoneArena has the same ratios that I calculated. Save yourself and AnTuTu's embarrassment, don't always trust GSMarena. But, I agree, I'm the one who has laughable tech knowledge... http://phonesabout.com/screen-to-body-ratio-calculator-for-smartphonetablet/

Meh the GS6 uses its space quite well while the Z3 and Z5 really don't. The Z5 5.2 display is only .1 mm bigger, has onscreen buttons, but somehow end up being way bigger than the GS6 which has a physical and capacitive buttons....

STEREO SPEAKERS up front. Stereo sounds when consuming media in your face. I would gladly have that than capacitive buttons occupying the space.

Naw that's HTC and Sony's mistake. More compact form factor beats stereo speakers you rarely use anytime, anyday or Apple and Samsung would have pushed for them in their board meetings. Or at least Samsung would have in their start from the ground up board meeting. The truth is no one really gives a crap about speakers, they like buttons though since the GS6 effectively has the slightly bigger screen in the applications where the software buttons do not disappear.

For the price they are asking, no thank you!. What a disappointing year it turned out to be. My only salvation is the new Nexus.

You guys didn't even mention the camera which was arguably the only sore spot of the Z3 I own. It also appears to finally have a new UI and full manual controls along with the new sensor and 5X lossless zoom. If this pans out and the results are more than marketing fluff, I'm without a doubt getting the Z5. It's not even close.

It's digital Zoom. not lossless zoom! That's practically useless. How do I know? I have couple of Sony SLT's at home including A99. Digital zoom is worse than nothing.

Parena , please do Mate S vs Galaxy A8 (not crappy SD615 but exynos SoC) Thnx

Unless you have money to burn, there's no rational reason to upgrade. I might pick up the Z3c now since they're practically the same too.

would a casing interfere with the fingerprint scanner?
