Sony Xperia Z4 Compact rumor round-up: all the small things

Sony Xperia Z4 Compact rumor round-up: all the small things
Sony's mobile business might be more of a burden on the company that a money maker, but this isn't stopping the Japanese tech titan from producing mighty fine Xperia smartphones. Well, they don't get everything right — no one does — but still, Xperia flagships never failed to stand out with their design, functionality, and extensive protection features, among other things.

The Xperia Z1 and Xperia Z3 were particularly special, as they were joined at their side by the Z1 and Z3 Compact. Packing flagship hardware power in a small footprint, these two are an oddity in the Android smartphone industry - one governed by what seems to be an unwritten rule saying "any smartphone below 5 inches screen size is basically a toy."

As the last saving grace of users looking for a no-compromise, palm-friendly phone, Sony's Z Compact phones have been enjoying a warm reception over the years, especially in minimalism-cherishing Japan, where the Xperia Z3 Compact topped the smartphone sales list for six days straight in April 2015.

Now that a good bunch of plausible information has surfaced, the Xperia Z4/Z3+ is a matter of fact, and Sony has discounted the Xperia Z3 Compact in the USA, we're thinking now is a good time to put together a Sony Xperia Z4 Compact rumor round-up. There probably aren't that many of you whose knuckles have turned white in anticipation of this one, but the Z4 Compact may rank highly in our "best of 2015" list. We'll see. We'll tell!


At this point, the Z4 Compact's design makes for a rumor round-up that's more confusing than anything. Knowing Sony, we expect an incremental update over the Z3 Compact, keeping its distinctive "rounded liquid reflection frame" — a special type of plastic with a translucent finish — paired with a set of bold color choices. Water and dust-proofing should be on board as well, and the general dimensions are probably going to stay the same. The Xperia Z3 Compact measures 5.00 x 2.56 x 0.34 inches (127 x 64.9 x 8.6 mm).

However, Sony could also consider moving in a different direction. You may remember the concept images that leaked after last December's gruelling hack attack upon the corporation. Just in case you don't, we're going to re-publish them. Coming straight from Sony, these designs represent an all-metal device that looks quite unlike former Xperia flagships or Compact-series handsets.

In all honesty, though, we can't see Sony heading down this path, as it would make for an awkward design mismatch between the Xperia Z3+/Z4 and the Z4 Compact. But everything is possible, and as you can tell by the Z4's naming scheme, Sony isn't a stranger to odd decisions.


Few days ago, a certain Sony E5663 and its spec sheet popped up on our radar. With a 4.6-inch 1080p screen, a high performance MediaTek MT6795 SoC, 3GB of RAM, 16GB of storage, a 20.7MP rear cam and a 13MP front cam, this sounds like the Xperia Z4 Compact in disguise. Nevertheless, we can't be 100% sure about that, as the E5663 could also be a region-specific device that won't see the light of day outside a given country.

However, our intuition weighs down towards the former, as it would be foolish (business-wise) of Sony to spec out a 4.6-inch flagship, only to contain it to a specific market. Speaking of specs, we believe Sony will replace the MediaTek chip with a high-end Qualcomm SoC — the Snapdragon 808 or 810 — for an eventual global release.
All in all, we really like the idea of a Xperia Z4 Compact materialising itself in this form. The 4.6-inch 1080p screen, in particular, will be extremely sharp, racking up a pixel density of 479 pixels per inch. That's overwhelmingly better than the Z3 Compact's 720p screen, which stands at 319ppi and still looks quite acceptable. Meanwhile, the purported spec sheet presents a no-compromise device in a pocket-friendly form - exactly what the Z4 Compact should be.

Unfortunately, there's no word on the handset's battery life. The Z3 Compact boasted great results in this critically important department, squeezing out 10 hours and 2 minutes of constant on-screen use out of its 2600mAh battery in our test. So let's cross our fingers and hope for another outstanding job from Sony!

Release Date

We can speculate all we want, but the truth is that Sony could announce the Z4 Compact any time it pleases! Considering there are test units of the Xperia E5663 already in circulation, this could mean the eventual Z4 Compact is close to finished and has a high probability of showing up before the end of the year, or even before the final quarter. So Sony should grace the impatient sooner rather than later! We'll keep you posted about any new developments regarding this, and other aspects of the Xperia Z4 Compact that manage to escape from Sony's walled garden prior to launch.

This could actually make sense! They the phone Z3+ instead of Z4, because the the Z4 compact will have a totally different design (and hopefully come with the Snapdragon 820 if it's close to release).

Waiting for a Compact Model form Sony with Snap 820. Let's see what will happen.

Not interested in the 2015 phones. I'll wait for the Cortex-A72 models next year. They'll be true 64-bits worthwhile and have amazing performance. IMHO 64-bits is completely useless on a device with less than 4GB Ram like current 3GB devices. 2015 is nothing but a pissing contest between Samsung and LG with ludicrous screen resolutions, meaningless camera terminology (laser focus... that's not laser focus but IR-focus so don't call it laser focus morons), ugly battery wasting UI's especially for AMOLed equipped flagship phones, the race for the thinnest slab, deluding people with inadequate battery-stamina (made worse through fugly UI's), inefficient Android versions coupled with overheating inefficient SoC's. No thanks.

I think 808 would be better.

MT6795 performs better than sd810 so how can sd808 be better than it?

Sony, please don't repeat your mistake on Z3+. Put an 810 chip on Z4 compact and it's already blacklisted on my shopping list.

It'll be nice if they bring the Z2's purple color back for the Z4C, or maybe make a *real* red model this time instead of that confused red-orange salmon color.

SD808 and a 1080p screen would be nice.

MT6795's performance is beween sd810 and exynos 7420, so why downgrade with sd808 :/

I keep thinking they're gonna skip the Z4 compact like they did the Z2 compact. Hopefully these rumors turn to reality!

No compromise and MediaTek don't belong in the same article. A snapdragon 820 would be much better. Also love the concepts and renders. Here's hoping!

Typical old school thinking. Wake up dude! Mediatek is coping really hard these days..... Snapdragon was really great but Qualcomm is lacking behind from current generation SoCs.

6. T-rex unregistered

Totally! Snapdragon is lagging behind while the others are leapfrogging it

Still, though, Mediatek is not friendly for developers and Sony supports developers with their AOSP for Xperia program. I really don't feel like Sony would/should go with a MediaTek chip if they want their developer customers to be able to use their latest flagships.

I also don't believe Sony will make compromises with its flagship level phones but 810 has scared manufacturers, i wish sony would go with 820

That problem was in 2013. Have seen mediatek devices running apps smoothly. Technology is always evolving but qualcomm is on the reverse mode.
