Sony Xperia Z5 follows the Z3+ – which is technically the Z4 in certain countries – and makes actual improvements. You see, Sony had this knack for releasing updates but failing in terms of enhancements. But the Z5 is an actual break from that “tradition” as it features changes that give it a fighting chance in the market. The Z5 was released together with the Z5 Compact and Z5 Premium in 2015 and is the middle child of that bunch. However, this looks to be the last of the Z line of phones as Sony intends to end the series.

Enter the Xperia XZ: the new line of flagship smartphones from Sony. This new line of phones contain the elements of what made a Sony device great but also making it feel new.

While it might not be fair to compare the Z5 and the XZ as one is obviously not going to be around for long, the Z5 still exists as of this writing.


For the Z5 to be labeled different from its predecessors it had to undergo several changes – and it did. While it still retains a glass back, the material is frosted instead of clear glass of the previous models. The edges are also rounded off this time and buttons have new placements. The ports of the phone are waterproof and it’s got fewer flaps this time around.

The XZ, on the other hand, uses a material called ALKALEIDO for its back which doesn’t look revolutionary and feels like the metal of other Sony handsets. While it does make the device look like a premium product, it suffers from being a fingerprint haven. The XZ also features a flattened top and bottom which makes it easier to stand the phone up.


With the competition taking display capabilities up a notch, Sony is still remaining in full HD territory. Both phones have 5.2-inch screens that have a 1080 x 1920 resolution. Both also have IPS screens with multi-touch gestures of up to 10 fingers. While the Z5 features scratch-resistant glass, the XZ uses Corning Gorilla Glass.


The Z3+ used a Snapdragon 810 processor and was a source of constant frustration. In a strange twist, Sony decided to use the same problematic chip for the Z5 claiming that they have fixed the issue of it overheating and crashing apps. While there are certain improvements, the problems still remain especially if playing graphic-intensive games.

The Snapdragon 820 on the XZ is a lot better and although there are times when apps loaded a little too slow, it still performs better than the Z5.


The Z5 only offers a 32GB, 3GB RAM variant but it has a microSD slot to expand memory to 256GB. The XZ comes in 32 and 64GB storage variants but all with 3GB RAM as well as expandable memory up to 256GB.


Who wouldn’t love a 23MP primary shooter, right? Both phones posses that kind of rear camera but the XZ just takes it up a notch with a 13MP front snapper which is better than the 5MP snapper of the Z5.


For all its improvements, Sony decided to stick with a 2,900mAh cell compared to the 3,100mAh of the Z3. Also strangely, they also decided that the 2,900mAh is also best for the XZ. All those said, the battery can last a whole day without charging.


If you want to stick within the same family when buying smartphones, you might want to opt for the Xperia XZ given the discontinuation of the Z line. However, if the specs of the Xperia line is not enough to convince you, going for the competition is the way to go.
