Sony Xperia Z5 in-depth review: pretty cool but can get warm

Sony's Xperia Z5 series came at a time when it almost seemed that Sony had lost the plot as far as premium smartphones were concerned. Phone makers like Apple, Samsung, LG and Huawei were unveiling new phones that were far superior to the Z3. So it was quite interesting to see the new Xperia Z5 series   at IFA in Berlin this September, and we ran a gazillion tests on the flagship Xperia Z5 to bring our consumers this in-depth review.

How good is the Xperia Z5?

The Xperia Z5 costs £550, even though Force Touch, curved displays or even a super premium finish does not make an appearance here. However, with frosted glass on the back and the interesting range of colours makes the phone an interesting one.

With plastic round edges and metal sides, Z5 also features a flatter and elongated power button which doubles up as a fingerprint sensor. The phone also holds a SIM tray and a microSD slot. Yet, despite having a width of just 7.3mm, it may feel thick to those who have tried curved screens on Samsung phones.

Sony Xperia Z5 in-depth review - Still hot, in a good way! And that camera...

Is the camera best in the world?

In terms of pure features, it is. The 23-MP Exmor RS sensor in the Z5's primary camera is by some distance the best in the industry. It takes pictures in as less as .3 seconds. The Clear Image Zoom feature that can zoom images up to 5X, lossless zooming technology, low light photography, f2.0 aperture round up a great camera.

However, as we found during our review, the image quality in 23MP mode is fuzzy around the edges and unimpressive.

Does the Z5 get hot, literally?

It does, especially when shooting videos. During the review, we found that apart from the camera, the Snapdragon 810 processor was also culpable for it. After you've finished shooting a video, you'll find the performance  sluggish and the phone warm to the touch.

Spec comparison: Lumia 950 vs iPhone 6s vs Samsung Galaxy S6 vs Sony Xperia Z5 vs HTC One (M9)

With a stellar display on which watching HD videos is pure fun, a super-intuitive fingerprint sensor in the power button, a long lasting battery, water-resistant body and great music quality, Xperia Z5 can claim to be among the finest smartphones in its category. However, it is not the best owing to some average features and an older version of Android holding it back. Sony have done a good job this time, but it could have been better.
