Performance & Battery Life
Four of the Z5’s Snapdragon 810 processor cores use Cortex-A53 architecture and run a 1.5 GHz clock speed, while the remaining four run a 2 GHz clock with Cortex-A57. Processing is aided by the Adreno 430 GPU and 3GB of RAM. The device comes with 32GB of internal memory storage and can be expanded with microSD cards.
These specs help the Z5 rank highly on synthetic benchmarks, and users won’t see any glitching or slowing down even when running lots of demanding applications. Snapdragon 810 may have had overheating issues (which are not present here, or really any other 810 handset released in the last few months), but never speed problems.
Undemanding display resolution, Android OS version adjusted for the most modern chipsets and a solid battery capacity of 2900 mAh are good indications that the Xperia Z5 offers just about the same autonomy as Xperia Z3+, which had a bigger battery. In fact, Sony claims as much. On one charge, the Z5 can last up to two days with normal use. Breaking it down further, the Xperia Z5 uses less power making calls and while in stand-by mode than browsing the web or any data communications over cellular networks. Compared with other handsets, which have measurably improved battery performance in recent years, the Z5 is about average.
There is no doubt that the 23-megapixel Exmor RS sensor takes photographs that are up there with the best smartphones. The sensor is in fact 25-megapixel, but the section used for 4:3 ratio images has 23 million pixels, while the section used for 16:9 ratio images uses 20.1 million pixels (the 16:9 have a greater horizontal resolution than the 4:3). This sensor and the Snapdragon 810 processor enable the phone to record 4K video clips with 30 fps, while the front-facing 5.1-megapixel camera can also record full HD selfie-video clips of the same density.
With a 2-step shutter button on the right side, which enables simple, fast and precise focus, it is clear that the Z5 offers both creative and technical options for taking photographs – just like more powerful compact cameras. This is aided by top-quality software from Sony, which provides great manual control of the camera’s settings.
The Z5 photos are up there with the best of the bunch, which currently includes the LG G4 and latest Samsung Galaxy smartphones, and the smartphone is particularly good at in low-light conditions with high dynamic range capturing detail in both highlights and shadow.
In fact, the Sony Xperia Z5 is equally precise when it comes to rendering colors and properly exposing shots in poor lighting conditions. What is even more important is that the Z5 can do those things speedily. The camera isn’t perfect , however, as it loses fine details along the edges of the image frame due to the wide angle lens. There is also a visible amount of digital noise on darker surfaces taken at night. But if you are looking for a camera that takes the best images at twilight, that’s the Sony Xperia Z5.
