We have barely gotten accustomed to the excellent Xperia Z3 that Sony churned out this holiday season, and there are already rumors emerging about the Xperia Z4. Exhale a sigh of relief, though, as the pesky six-month upgrade cycle might be gone for good with the Z4, as Sony is apparently planning to pull out all stops with its next flagship.
The sources claim that we will be looking at an Xperia Z4 with a 5.5" display, bearing the nutty 1440x2560 pixels Quad HD resolution, and the phone will be powered by the upcoming Snapdragon 810 chipset, meaning crazy power under the hood. Not only that, but the leakster tips that Sony might equip the Z4 with 4 GB of RAM, to take full advantage of the Android Lollipop's support of 64-bit architecture, and more than 3 GB of RAM addressable memory. Gone will be the days when flagship Xperias came with 16 GB of internal storage, as the Z4 is said to arrive with 32 GB out of the box, though nothing is mentioned whether it will have a microSD slot, or not.
That's not all, though, as Sony is rumored to equip the Z4 with a new curved Exmor camera sensor, which is likely to keep the same 20 MP resolution, but offer a better camera experience than what we have now in Sony's phones. The source also says that the Z4 will support LTE Cat. 6 download speeds of up to 300 Mbps, and Bluetooth 4.1, but since these are a given with Snapdragon 810, there's not much news here. What's news, though, is that Sony is planning to put amplifiers behind its signature stereo speakers at the front, similar to HTC's BoomSound kit, for a superior audio experience. If at least some of this pans out, it's no wonder that Sony might finally ditch the six-month upgrade cycle - the Xperia Z4, as laid out in this unsupported rumor, is shaping up to be as futureproof as they come.
Let's not forget the tweet from the famed Sony leakster Ricciolo last month, that says Sony will be decking out the Z4 to the gills, screen res included. Where there's smoke, there's usually fire, though nothing is mentioned whether the handset will still be waterproof and with great battery life, which are becoming Sony's signature features in the Android crowd. We'd assume that the Z4 will be roughing it as much as the Z3, though that purported Quad HD panel might take a bigger toll on battery life than necessary.
