Sony Xperia Z4 vs Sony Xperia Z3: What’s different

XperiaZ4 comparision

After much deliberation, Sony has at last announced its latest flagship the Xperia Z4. The phone comes powered by the Snapdragon 810 SoC, and is more compact, sleek and more powerful than its predecessor. But the real question is if the Xperia Z4 is a worthy upgrade over the Xperia Z3, or just the classic case of old wine in a new bottle. Let s find out how different these two flagships really are.Display

The new Sony Xperia Z4 borrows the 5.2-inch Triluminos display set at 1080p from its predecessor. On the display front Sony seems to have decided not to go ahead with any drastic changes and it seems that the company ditched the idea of employing a QHD display owing to power consumption issues.

Processor and RAM

This is one department that sees big changes. Where the Xperia Z3 was powered by a 2.5GHz Snapdragon 801 quad-core processor, the new Xperia Z4 has an octa-core Snapdragon 810 chipset under the hood. The processors are paired with an Adreno 330 GPU and Adreno 430 GPU respectively, and 3GB of RAM each.


Sony Xperia Z4 offers 32GB of onboard storage along with a microSD card that can accommodate up to 128GB. The Xperia Z3 on the other hand came with an option of 16GB/32GB internal memory and was also expandable up to 128GB. It s good to see Sony still offering the crucial expandable memory card slot even when its competitors like Samsung Galaxy S6 are excluding the feature fearing design constraints.


Xperia Z4 shares the 20.7-megapixel primary sensor with the Xperia Z3, which boasts Exmor RS image sensor and 4K video recording capabilities. On the front however, Sony has bumped up the specifications keeping in mind the selfie craze. In place of the 2.2-megapixel camera, the Xperia Z4 now boasts a 5.1-megapixel camera with wide angle lens, as well as digital image stabilization.


Despite the bump in power, strangely the Xperia Z4 comes with a smaller 2,930mAh battery, as opposed to the 3,100mAh battery on its predecessor. Sony has however included its STAMINA mode, which should help get the best out of the smaller battery.


Xperia Z4 comes preloaded with Android Lollipop 5.0. The Xperia Z3 was launched with KitKat out-of-the-box, but has recently been upgraded to Lollipop as well. So even on the software front we don’t see drastic changes between the two successive generations of Xperia handsets.


Just like its predecessors, the Xperia Z4 too is resistant to water and dust. It boasts IP68 certification, but the talking point is that Sony has done away with the plastic flaps covering the USB port and the 3.5mm audio jack.


As we can clearly make out except for the upgraded chipset, slightly revamped design and better front camera, Xperia Z4 doesn’t really give many reasons for users to upgrade from the Xperia Z3. While we appreciate the fact that Sony has not ditched the water and dust resistant features but on the contrary we still feel that they could have come up with some serious upgrades at least on the camera front, like Optical Image Stabilization.
