It's hard to believe at first that a phone is water resistant... and we're not talking about splashes, that's a bit of a challenge. What we're talking about is... submerge it in a fish tank and nothing happens to him. That's exactly what the new Sony Xperia Z which has just been presented at the CES fair and, from what has been said about it, is sure to be one of the models that will set the trend.
Thanks to meeting the standard IP57, the rest of the most important features of this terminal you can see them in this link, the new model of the Japanese company offers resistance to dust, which is always interesting, but what is really remarkable is that it also supports immersion in waterThis is evidently possible thanks to its unibody casing, which means it's built in a single piece, preventing any gaps through which liquid can leak. Furthermore, the device states IP55 / 57, combining protection against water jets and limited submersion.
This could be seen in the product presentation video, but you can always think that it is biased information ... but it is not the case, since in a video of GSMOnline live you can see how a Sony Xperia Z is inside a fish tank and works normally:

What does IP55/IP57 water resistance really mean?
When a device is said to be Waterproof is not the same as “waterproof”. IP certification is governed by the standard IEC 60529 and consists of two digits: the first indicates the dust protection (0 to 6) and the second one protection against water (0 to 8). In the case of the Xperia Z, the first digit “5” assumes that some dust may enter but without affecting operationThe second digit “5” certifies resistance to water springs under moderate pressure, and the “7” ensures that it withstands complete immersion up to 1 meter for 30 minutes in fresh and static water.
It is key to understand the physics behind it: the water we normally use contains salts and compounds dissolved in water that makes it conductive. If liquid gets inside while the phone is on, it can cause a short circuit. That's why protection is achieved by seals and gaskets that prevent the entry of water, and always with port plugs tightly closed.
Design and sealing: ports, covers and good practices
The Xperia Z opts for a design OmniBalance, with tempered glass on both sides and a chassis that gives continuity to the straight lines. Its “unibody” construction and the port covers (microUSB, microSD, microSIM, and audio) are the basis of its tightness. This solution provides a clean and elegant finish, but entails two considerations: Identifying each compartment is not immediate and opening/closing lids frequently can be difficult. wear of the joints over time.
To take advantage of the resistance without surprises, it is advisable to follow these recommendations common sense:
- Before wetting it, visually check that all covers are tightly closed and without any gaps.
- Use only in sweet water and calm. If it comes into contact with salt or chlorinated water, rinse it with fresh water and dry it carefully.
- Do not press buttons or connect cables underwater and avoid high pressure jets or steam.
- If you detect deterioration in a cover or gasket, replace it before exposing the equipment to water; wear and tear is not always covered by warranties.
The edge includes a point for safety strap, useful if you plan on taking photos near water. And while the caps maintain the design, some users may prefer wireless charging so as not to open the USB port often.
Camera, display, and everyday performance
Both the camera, as expected since it is from 13 megapixels with Exmor RS sensor, makes high-quality recordings and photographs. It has modes such as Panoramic sweep, Burst with different speeds, HDR for photo and HDR video, digital zoom up to 16x, face/smile detection and the possibility of take photos while recording video. Focusing is fast and noise is contained for its sensor size.
In addition, it is also appreciated that the quality of the screen with technology Mobile Bravia Engine 2 It's really good: 5 inches Full HD and high pixel density that favors sharp text and vibrant color. As with other panels of its time, the viewing angles They are the least spectacular section, but the multimedia experience is outstanding.
In terms of performance, the Xperia Z is equipped with a Snapdragon S4 Pro with 2GB of RAM, enough to run Android smoothly, play demanding games, and multitask without bottlenecks. The battery life 2330 mAh leans on the STAMINA mode, which limits data usage at rest to extend battery life when the screen is off, and offers options to adjust connectivity or synchronization based on profiles.
In connectivity, there is no shortage NFC, Bluetooth 4.0, MHL for video output, Wi-Fi with Miracast and screen mirroring, as well as GPS/GLONASS. With headphone audio, it offers a good balance of bass and treble.
Another very interesting video
Other details that are quite clear in another video, in this official case, is that both the camera, as expected since it is from 13 megapixels with Exmor RS sensor, makes high-quality recordings and photographs. In addition, it is also appreciated that the quality of the screen with Bravia Mobile technology is really good. Undoubtedly, the rest of the companies will have to “row” a lot to overshadow this device.

Finally, it is clear that the Android 4.1.2 operating system It works like a charm and fluidity is the predominant feature in the handling of the Sony Xperia Z. In addition, it offers consumption control options of energy that will be of great help, although this must be seen live and in person to be able to properly assess its functionality.
The Sony Xperia Z proves that design y resistance can coexist: IP55/57 certification, solid construction and advanced camera functions, with the added value of power settings and a very careful multimedia experience. Respecting the limitations of the standard and good usage practices, it is a companion that tolerates everyday accidents with ease.
