Every time Sony launches a flagship handset, a question arises, why can’t the company succeed in the global and local mobile market? The answer is not in the quality of its products, which are generally very good, even excellent, but because of the ego of the Japanese company, preventing it from cutting prices to compete full force in the marketing level against the South Korean and Chinese competitors.
The Z5 comes with a full HD 5.4-inch screen, the colors are rich and the backlight is good, but the device tends to heat up when it is using a car charger. This causes the device to automatically decrease the backlight a little, which is troublesome when trying to navigate in direct sunlight.
The Xperia Z5 does not come with a breakthrough design and is very similar to the Z3 model, it has rounded corners and is very pleasant to the touch. Sony finally gave up on the charger cover. The thickness of the device is reasonable – 7.3mm and weight – 154 grams.
Sony has chosen to implement its fingerprint mechanism on the right side of the smartphone, along with the power button, as opposed to other companies that integrate it to the back or front of the device. The fingerprint mechanism on the Z5 is very successful. It is fast and rarely misses. The only pity is that it requires a dual action: first you must click a button and then lay the finger to identify and unlock the screen.
The Xperia Z5 is waterproof upto a depth of 1.5 meters, and for a duration of 30 minutes. However, Sony intended for it only as resistant to rain or in case a glass of water spilled on the smartphone. This won’t protect your phone when taking a dive in the pool.
The Z5 has a very good performance and doesn’t suffer from "stuttering" or slowdowns.
Sony introduced here a new 23 megapixel sensor. Photographs in daylight produce excellent, sharp pictures with rich colors that aren’t overly saturated. In some cases, the results can even compete with standalone cameras. The selfie camera delivers mediocre results (5 MP sensor).
The Z5's performance is worse than the Z3. Here the battery lasts up to 10 hours, including when using the Stamina mode. This mode disables WiFi and cellular data while on hold (when the screen is off), except for applications that the user decides otherwise, for example Whatsapp and E-Mail.
The Z5 is a smartphone with a high quality camera, but the battery is disappointing compared to the Z3 and the price itself is expensive, especially since it is the premium model in the series.
