New Delhi, Oct 25 (IANS): Japanese electronics major Sony launched its new Xperia smartphones this week - Z5 and Z5 Premium - priced at Rs.52,990 and Rs.62,990. We got our hands on the Xperia Z5 dual and here is what we think of it:

What is good?

The phone comes with the same design and look as the Xperia's Z series. Other than the dedicated camera button for the quick launch camera app, the addition seems to be the fingerprint scanner on the side. What is interesting is the positioning of the scanner: the power button doubles up as the scanner. No other phone has a scanner on the side.

The Z5 is also IP65 and IP68 certified which means it is dust proof and water proof. We held the phone over a stream of running water and it functioned properly even after the cold bath.

The phone's 5.2-inch screen has a good 427 pixel density and there were no problems with viewing angles. Watching videos and gaming is also a good experience, combined with the phone's awesome sound.

The Z5's 64-bit octa-core Qualcomm Snapdragon 810 processor, along with a 3GB RAM unit, can take most of the things thrown at it, including heavy games.

The smartphone's camera is the best of the features on the phone. The camera, in combination with several modes that are usually seen in all Z series phones, can take wide angle pictures. The rear 23-megapixel camera performs really well in any condition. The front five-megapixel can also take wider selfies and groupies.

The phone's 2,930 mAH battery is a fair performer as well keeping in mind that it comes with ultra stamina and stamina modes to preserve its charge.

Interestingly, in terms of connectivity, the phone supports dual 4G nano-SIM cards and also VolTE, which Reliance's Jio Infocomm will launch by the year-end. Also, the Z5 comes loaded in terms of storage. It has 32 GB internal memory that can be expanded to 200 GB.

Other features like NFC, Bluetooth module 4 and Wi-Fi and Wi-Fi direct are also available on the phone. The company also seems to be banking on integration of other Sony services like its television channels and Playstation to attract more users.

What doesn't work for the phone?

Be it customer dissatisfaction or lack in innovation, the Japanese major seems adamant on retaining the look and design of the Z series.

What seems to worry us is the sudden heating of the phone when the battery level reaches a certain level or exposure to heavy games for tad longer duration. The positive is you could cool it with a cold water bath. Also, the phone ranks a little lower (around 7,000 points) than other flagship rivals in An Tu Tu and Geekbench 3 scores.

The front camera should have come with a flash keeping in mind the price. A 4GB RAM would also have been fair.

Verdict: It is not new for us as well for Sony to be criticised for bringing overpriced phones to the market; so we will maintain a stoic silence. Keeping in mind the fans of the brand, the phone is definitely an improvement over the previous Z series as it comes future ready with a fingerprint scanner and VolTE support. Should you buy it? There might be other options to consider than zeroing in on the latest Z.
