Last year, Sony had a great successor with its Xperia Z3 flagship and even now, towards the end of 2015, this model is still more popular than its successors. It’s a bit unfair to compare it with Samsung’s Galaxy S6, which houses a more powerful processor, but they have in common a glass back and we thought it will be interesting to put them side by side.

Designs and Displays

The Xperia Z3 has a square body with a metal frame and nylon corners which are protecting the device against accidental falls. Sony placed the rear camera in the upper left corner and the screen has three capacitive buttons integrated in the lower part. The back is made of Gorilla Glass 3 and it’s available in five variants of colors: Black, White, Copper, Silver Green and Purple. Its dimensions are 146x72x7.3mm, it weights 152grams and its water and dust resistant. Its display measures 5.2-inch and it uses the IPS LCD technology which delivers colder tones. It’s sharp enough with a Full HD resolution, but this will result in a much lower pixel density of 424ppi.

The Galaxy S6 features a glass back as well, but it’s made of Gorilla Glass 4 and its color options are White Pearl, Black Sapphire, Gold Platinum and Blue Topaz, but its frame is simple, made of aluminum and the corners are more rounded. Also, the device is much slimmer (6.8mm) and lighter (138grams), but it’s also shorter and the screen has a size of 5.1-inch, but it’s definitely brighter and more vibrant, because it uses the Super AMOLED technology and its resolution is QHD at 577ppi. Unfortunately, this type of screen is a battery killer and the Galaxy S6 doesn’t have a big cell. Anyway, the advantage of this flagship is the fingerprint scanner which was built inside the home button.


Samsung has worked on a faster processor for the Galaxy S6 and the Exynos 7420 obtained high benchmarking scores. The processor was built using a 14nm process technology and it has four cores running at 1.5GHz, while the other four cores are clocked at 2.1GHz. The device has a stunning performance especially because the internal configuration supports 3GB of DDR5 and a memory which is available in variants of 32/64/128 GB. Unfortunately, there’s no room for expansion, so you’ll stuck with one of these variants.

The Xperia Z3 uses an old 32bit Qualcomm MSM8974AC Snapdragon 801 chipset which is powered by a modest quad-core 2.5 GHz Krait 400 processor which is backed by 3GB of RAM, while the internal memory comes in variants of 16GB and 32GB, with the possibility to add a microSD card and expand their capacity up to 128GB.

Cameras and Batteries

The Xperia Z3 has a rear camera which supports a higher resolution of 20.7MP, offering up to ISO 12800 and 4K video recording, but it’s limited in features, supporting autofocus and LED flash, but it lacks OIS. If you’re a selfie lover, then you won’t be very satisfied with the pictures taken with the 2.2MP front camera of the Z3. The Galaxy 6 has a better 5MP front camera, but the snapper on the back supports 16MP. The resolution is not as important as the software and we can guarantee you that this phone performs quite well and the images are very colorful and accurate.

Both phones have batteries which support wireless charging, but the Galaxy S6 has a smaller battery of 2550mAh, which offers 17 hours of talktime, while the Xperia Z3, with its 3100mAh unit, supports 16 hours of talktime, according to GSMArena.
