We have seen a number of powerful smartphones that offer poor in-call quality, but fortunately, the Sony Ericsson Xperia X10 is not one of them. Actually, the X10 is way above average with this respect and as a whole, we rate it 8/10. Our only gripe relates to the slightly muted voices, because they sound less than perfectly realistic, but everything else is great. We didn’t have any problem understanding our callers even on a single occasion, although they claimed they could hear unobtrusive environmental noise when we used the X10 while walking along a busy street.

The manufacturer claims the battery should be able to provide 8 hours of continuous talk time and keep the handset operational for 425 hours in stand-by on 3G networks. In order to achieve such a battery performance, however, you will have to switch off all social networking updates, since they drain the battery fast.


In terms of hardware, the Sony Ericsson Xperia X10 is nothing short of a marvellous device. It´s as easy to notice as taking a look at its specifications and the impression is confirmed when you get it in your hand. The build quality is very good, the screen is huge and features wonderful sensitivity, you get virtually all extra features you might need, including 3G, Wi-Fi and GPS (even navigational software). The 8-megapixe camera is great for taking pictures outdoors and happens to be the best you can find on Android-based handsets today. The video capture capabilities of the device are more than satisfactory as well, even if it does not deliver HD video capture. The in-call and audio playback quality are extremely pleasing as well.

We cannot but congratulate the manufacturer on the concept behind Timescape and Mediascape. The personalization is enjoyable and Sony Ericsson has done great, pre-installing applications to add Microsoft Exchange support and make up for one of the shortcomings of the ageing Android edition. All this contributes to a contemporary smartphone of a very high quality that definitely stands out from the crowd.

Of course, the handset is not without its shortcomings as well, say, lack of landscape QWERTY layout when composing messages, missing audio player equalizer, clumsy browser etc.

Alongside of the HTC Sense, the UX interface is somewhat harder to get used to, but the learning curve is not that steep and you just need to spend some time with it to begin feeling at home. Still, there will be lots of questions like “where is the option for...” and “What happens if I press this...”. One of the issues the manufacturer does need to address is the lagging software. We are pretty sure the severe slowdowns in the operational speed of the device are software-related, because the 1GHz Snapdragon processor is extremely snappy indeed.

What other options do you have? What about the fiercest rivals of the Sony Ericsson Xperia X10 today?

-    Google Nexus One – it is based on Android 2.1 and despite the lack of personalized interface, the device offers proper integration of social networks and eye-candies like Live Wallpapers. Its screen is smaller, but utilizes AMOLED technology and delivers impressive image quality. Moreover, the handset supports multitouch.
-    HTC Desire – based on the same hardware and software as the Nexus One, but runs HTC Sense that offers a number of personalization options.
-    HTC HD2 - if Android is not your cup of tea, but you still need a device with huge screen, this is your only option today. The handset runs Windows Mobile 6.5, but comes with all the advantages of HTC Sense.
-    Motorola DROID – even if less spectacular than the above mentioned cell phones (at least in terms of hardware), the device is a solid option with proper functionality. It is based on Android 2.0 (will get updated to version 2.1 soon) and sports a hardware QWERTY keyboard that may prove to be decisive for heavy texters.

The Sony Ericsson Xperia X10 is one of the best Android handsets today, but what it needs to become perfect is software update to the latest version of the operating system and a fix to resolve the several bugs and lagging issue. We hope the manufacturer responds fast in order to make its flagship device even more appealing than it currently is.
