Sony is still loyal to announce a new flagship every 6 months, although the difference between the new flagship and its predecessor is almost nothing. Sony used the IFA2014 to unveil the Xperia Z3, and in this AW Center article we compare Xperia Z3 with Xperia Z2 to see whether it is worth updating from Xperia Z2 to Xperia Z3 or not?
For those who just want us to get to the final conclusion, we should say if you are one of those who already own an Xperia Z2 (or even Xperia Z1), then the Xperia Z3 is not really a phone worth updating, but if you are going to buy a high-end Android phone, then we should admit that Xperia Z3 could be on the top 3 list at the moment. The other 2 candidates at the moment are HTC One M8 and LG G3. We haven’t forgotten about Samsung Note 4, but this new Samsung’s 5.7-inch smart device is more a phablet than a phone and we don’t believe in comparing it with 5.0 to 5.2-inch phones.


Now, for those who prefer a detailed comparison, let’s start with genera specification comparison:

Xperia Z3 vs Xperia Z2: Design

This is where you can find the most changes as Sony has kept the OmniBalance" design language but reduced both Xperia Z3’s weight and thickness so the device is considered more user friendly, ergonomic wise.
In overall Xperia Z3 is much easier to hold with hands and we believe it is the only solid reasons for Xperia Z2 users to upgrade to Xperia Z3.

A new app drawer icon and larger icons are almost all the changes.


Xperia Z3 vs Xperia Z2: Battery
