The Sony has a design very special thanks to the transparent layer is at the bottom which draws much attention and gives a touch of elegance to your computer. It also has a backlight with three multicolored LED lighting that will change color according to the images to be displayed on the screen. This part includes the icons of the touch keys Backspace, Home and Options. One thing to clarify is that many people think that this part transparent icons where they are tactile, but those people are wrong, and that above these icons are three points that are tactile and this is where you must press and not directly the icons.

I personally liked the design enough, the same size and weight are ideal for day to day, is lightweight and very comfortable to carry, especially in his pockets. Another good thing is the materials design, one notices that are of very good quality, but is plastic with a rubber cover, giving you greater security when making the team with his hands.

Begin to Review their design, side by side:

In the front are mainly its 3.5-inch display, which unfortunately is a fingerprint magnet and often dirty very easily, so I recommend that you buy a protective film if you plan to purchase this equipment. Above we see the familiar logo SONY with the headset, ambient light sensor and proximity, and finally see the VGA camera for video calls.

FM Radio

The Sony Xperia U features an FM radio receiver with RDS (Radio Data System).

Signal reception is pretty good, although we know it depends on the type of headphones that are occupied and the area where one is. As for sound quality, I must say that you hear quite well but lacks a little strength by volume.

The good news is that the integrated FM radio and Track ID application so you can easily identify the song being broadcast on the radio.

Video Player

The video player that incorporates the Sony Xperia U is not as complete in terms of settings but still saves. Plays 3GP, ASF, MOV, MP4 and WMV at a maximum resolution of 1280 X 720 at 30 frames per second. You can enable or disable the Mobile BRAVIA Engine which greatly improves the video quality, highlighting the colors, definition and shine.

You can also adjust the brightness, enable or disable the option to automatically rotate the screen according to the team’s position allows you to enable or disable animations and also lets you adjust the timeout of the backlight when you have a video paused.

I personally thought it was going to see some change around here but remains exactly equal to the interface that has a younger brother, the Xperia Arc S.


The Sony Xperia U has A-GPS (Assisted GPS) so you can use the Google Maps application that comes built into the operating system so you can know your current location or ask directions to a place.

Sony Xperia U image 29

But if you do not like Google Maps, you can download the application Wisepilot navigation, maps and find your current location. There is also Waze, a Social GPS which lets you make use of GPS equipment.

The team takes about 5 to 10 seconds to connect with satellites to determine your location, as long as you own an internet connection active. If you have no internet, the computer will take a little longer to connect.


The screen incorporates the Xperia U is the LED-backlit LCD with BRAVIA Engine and has a size of 3.5 inches. Its resolution is 480 X 584 with a density of 280 pixels per inch t 16 million colors. This display has a 16:9 aspect ratio, is of the capacitive and supports multi-touch.

The screen quality is excellent, has a very good brightness, excellent contrast and definition, although the colors are not as outstanding as one would expect. The sensitivity of multi-touch screen works very well and we find the famous “ghost” images when playing very fast or at the time of enjoying a game. We tested also in broad daylight and behaves very well.


The Xperia U has two sound sources: The headset and speaker.

The headset I must say I quite liked it because you sound delivers a clear and strong, which is not saturated at all if you put it at full volume, really remarkable to have this kind of audio calls.

Sony Xperia U image 32

The Sony Xperia U has a single speaker, so we appreciate the audio is in Mono. The speaker is located on the back of the computer, but thanks to a small curve that has the Xperia S in the back, the sound does not diminish when the computer is on a flat surface, so that is appreciated.

The audio quality delivered by the speaker is good. It gives you a crystal clear sound with very good bass and very loud sounds. The good thing is that to have the volume to near maximum, the sound does not bother at all and the audio is not distorted.

Operating System

Android Gingerbread 2.3.7 is the version of operating system which operates the Sony Xperia U. The good news is that this team will soon upgrade to Android Ice Cream Sandwich, because their hardware is compatible.

The system works very nicely, going very fast and I must say I thought it would not run so well, but the team surprised me. At no time gets slow and I dare say you have a very similar experience to be with a computer with 1.2 GHz processor

Home Screen

The Home Screen is fully customized by Sony Timescape interface and has 5 desktops that are fully customizable. You can customize with 3 animated backgrounds and 18 funds of “Xperia”. You can also change the graphic theme for another 7 created by Sony. You can also create shortcuts to your applications, create folders, shortcuts and widgets.

Over here we can see the contacts menu which has a different interface to that already seen in other family members Xperia. You can add enough information to a contact as Name, Last Name, add image, number, email, IM address, groups ringtone, management, organization, notes, alias, web site, birthday and anniversary.

The Media Gallery is the same as the Xperia includes S with the difference that here you will see a 3D section for those photos you’ve captured using the 3D panoramic sweep. Also continue to use graphic design made by Cooliris .

We also have some unique applications of Sony you the detail below:

LiveWare Manager> This application is ideal for those who often use Bluetooth devices such as headsets or hands-free, and allows you to customize a profile for each device. For example, if you connect a Bluetooth headset, you can program the computer to start the music player automatically.

Power saver> With this application you can program the computer for some time to turn on or turn off some components. For example, at 18:30 I want to turn off the Bluetooth, turn on the Wi-Fi and turn off automatic synchronization.


The Sony Xperia U features Wi-Fi 802.11 b / g / n, Bluetooth 2.1, 3G/HSDPA/HSUPA, Wi-Fi hotspot and DLNA.

In addition the team is capable of supporting GSM-GPRS-EDGE 850/900/1800/1900 MHz and HSDPA-HSUPA 800/900/1900/2100.

We liked how well it worked the issue of signal and coverage of the team, as it has a good signal reception and good data transfer speed. Also try it with DLNA to play video in HD (recorded from the same camera of Xperia U) and never had a break in play as it happened on other computers to have a low transfer rate. And finally we tried using it as Wi-Fi Hotspot and the speed was quite good too, but equally it also depends on the operator.

We tested the Xperia Bluetooth 2.1 U of transferring an MP3 file of 4.2 MB between our protagonist and Lumia Nokia 800 and the transfer was completed – according to our stopwatch – in 38 seconds.

The external battery for Sony Xperia U is of the type Li-Ion 1320 mAh operating at 3.7 volts and the battery according to the manufacturer offers a range of 260 hours of standby mode 2G and 472 hours in 3G. While in call mode get 7 hours in 2G and 3G mode 6 hours.

We tested the battery performance, starting charging the battery by leaving overnight. At 06:30 in the morning turn on the computer and it connects to internet immediately and so is the whole day. On leaving home, (06:45 – 97% battery) connect my Bluetooth headset and leave the player playing music with standard, while on the road doing my job I receive some emails and mentions on Twitter. (07:30 – 82% battery) came to the office and let the computer desktop on standby throughout the afternoon and sometimes I WhatsApp or chatting by using Twitter. (17:30 – 32% battery), I leave the office, connecting my Bluetooth headphones and listening to music again, while I’m using Twitter and WhatsApp. (19:00 – 11% battery) came to my house and the cellular and begins to realize that you have low battery.

In short, the battery lasts about 12.

Final opinion of the Author

The Sony Xperia U is a team that I personally liked, reminds me of the Sony Ericsson Xperia Ray, a team that I had exquisite taste, but we could have the opportunity to do a review. The design is the same as its big brother, the Sony Xperia S, but with the difference that the team is smaller, more compact, more comfortable, and so on.

The quality of the screen, although it is smaller, is very good and not be uncomfortable when typing on your keyboard. The camera I was surprised, I expected to have lower quality but I was wrong, both in video and photos.

I also liked the audio, the speaker sounds great as the music played through headphones, complete and integrate an equalizer with several effects that significantly improve the sound.

And the operating system flies on this machine, it works great, one is not slow in the system and loads forever.

Would I buy this team? The answer is YES, because it is a very complete team, works very well and its price is not as expensive as one can imagine, I recommend it 100%.


The team is available at zero cost Entel plans from media and from CLP $ 199,990 in prepaid.

The Unmissable

  • Good camera
  • Good design
  • Good screen
  • Will be updated to Android 4.0 Ice Cream Sandwich
  • Well-rounded team

The unpresentable

  • Only 4GB of memory and is expandable with MicroSD cards
  • The battery life is not the best
  • LED notification light barely visible
