Just one glance at these two smartphone side by side, and you'll never notice that they are two different phones. Both Samsung Galaxy Note 4 and Sony Xperia Z3 have a quite a similar look, thickness, and screen size. However, we're going to compare and contrast these two smartphones based on their features and specs, and their pros and cons.

Both of the phones have the same RAM, 3GB. They also operate on the same operating system, Android 4.4. The size of the screens are also quite similar, but Note 4 has a slightly bigger one. Note 4 has a 5.7-inch display compared to Xperia Z3 which has a 5.2-inch screen.

When comparing the cameras, Xperia Z3 has a better camera, as it has 20.7 MP with maximum ISO of 12800. On the other hand, Note 4 has a 16 MP camera, but with Smart OIS. For those who love to take "selfies," Note 4 might be the better choice since it comes with 3.6 megapixels with f1.9 on the front camera, instead of Xperia Z3 that only has 2.2 megapixels.

When comparing storage, Note 4 steals the spotlight with 32GB internal storage, while Xperia Z3 only has 16GB. However, the storage of Xperia Z3 can be expanded up to 128GB, which is quite a large number when compared to Note 4, which can be expanded up to 64GB only.

When comparing battery life, Xperia Z3 seems to be more promising as it offers two days of battery life. However, Note 4 makes up for the weaker battery life with its fast charging feature.
