Primer análisis xperia ARC

Sacado de una página rusa, es un buen tocho pero sirve para aclarar muchas cosas:
Full review of Sony Ericsson Xperia arc: very stylish Android


In early 2011, in Las Vegas at CES was presented smartphone Sony Ericsson Xperia arc, which is quite unexpectedly became one of the main trends of the whole event.

The fact is that at that point arc was the thinnest smartphone in the world (8,7 mm), the only one who has worked on a version of Android 2.3, and also has parent technology company Sony: camera sensor with Sony Exmor R Backlight technology, BRAVIA mobile engine for post images on the screen in preview mode.We've already left a very detailed article about this smartphone, but with the advent of the commercial sample is only to check the battery life and the quality of images and video.


After the announcement Xperia arc Russian price was discussed within the 26-28 thousand, in the end we are dealing with the lower boundary of the range. The device goes on sale at 25,990 in early April. Agree, the price for the flagship and extremely interesting product came out very reasonable.The nearest competitors LG Optimus 2X and Samsung Galaxy S II will come later (in May) and will cost significantly more (33 and 37 thousand rubles, respectively).So, taking into account an adequate price and soon Sony Ericsson Xperia arc obtained by one of the most interesting products this year, with what the company wants to congratulate you.
Mistakes of the past (Xperia X 10) fully into account, new products in this series quite different in terms of perception. In this article I want to share their impressions from using the final sample Xperia arc.

Let's talk first about the hardware.

Hardware platform, the battery

The smartphone is based on a platform of Qualcomm QDS8255 1 GHz, this second generation of chips Snapdragon. Theoretically, the difference is described by lower power consumption, better optimization, but in practice it is almost the same as in the first generation (QDS8250). Consumption Smartphone Android - sick theme, and with the growth characteristics of all it only gets worse. For example, HTC Desire HD, running on the same chip, and can not stand daylight under normal loads. The situation with the power of smartphones Sony Ericsson is better, and in real life arc is slightly longer than competitors with similar parameters.


Of the top Android is a leader Samsung Galaxy S, due to more efficient processor Hummingbird (marking S5PC110), as well as graphics accelerator PowerVR SGX540 and AMOLED-screen performance superior battery life of devices from HTC about half.

Sony Ericsson Xperia arc running about the same as what can be considered an excellent indicator for Android, while not comparable to the iPhone, Symbian). Under intensive load time is reduced to one day, this is again normal for Android, there's nothing you can do.


Thus, the platform - a single-core chipset Qualcomm.

At the same time at CES and MWC were announced dual-core smartphones Motorola Atrix, LG Optimus 2X, based on the Nvidia Tegra platform 2.But as far as the two nuclei are effective in smartphones now?Nvidia promises a general reduction of energy consumption at the expense of such an architecture, but other indicators of increased (two cores at 1 GHz, resolution, screen, recording and playback in 1080p), this advantage disappears.Total: smartphones Tegra 2 operate exactly the same as single-core predecessors, a light day.Actually, the detailed testing of LG Optimus 2X can be found in our full review . The real advantage of the platform from Nvidia - a record and playback video FullHD (1920x1080 pixels), high rate of all other activities related to graphics, gameplay.This Qualcomm Snapdragon provide the same degree can not.

On the other hand, all existing games for Android does not require dual-core processors and even not fully charged the current generation of accelerators (PowerVR, Adreno 205), today it seems more a marketing advantage, rather than real. Producers, indicate the advantage of the hardware platform, but to demonstrate this advantage is obtained while only a couple of examples related to the video.

Benchmark Neocore

So, discarding the marketing delights, we can conclude that for the beginning of 2011 SE Xperia arc looks quite modern solution with excellent performance, very smooth interface, animation effects that we demonstrate in the overview videos. Compared with the advantage of X10 is very noticeable, although the frequency of the processor is identical.In all this there is merit a separate graphics accelerator Adreno 205.

Benchmark Quadrant

But to compare the results of similar tests on synthetic LG Optimus 2X:

And Samsung Galaxy S i9000:


Memory size is 512 MB (internal), from which free little more than 300 MB, 512 MB RAM, performance averages.Android version 2.2 and higher allows you to install applications on a memory card, so that's not the applications, but rather a total lack of memory.

Smartphones from Motorola, Nokia, Samsung - all have built-in array to 8-16 GB of what Sony Ericsson is responsible 16 GB memory card included, so that, in general, we get parity.

Т
Also as part of the hardware platform would be desirable to raise the issue with the video. Display Xperia arc has the technology Sony mobile BRAVIA engine (used in TVs parent company) for pre-processing the signal, eventually the quality of video images when viewed in some ways better.

Coupled with the filter Live Color picture on the smartphone screen more clearly, contrast and more realistic. However, it should be understood that this feature - the software, not hardware, it can be turned on and off in the settings screen, and it works only for graphics, but not on the menu, for example.

Screen

The screen is very good, the difference with X10 noticeable immediately. And that's not the technology Sony BRAVIA, it is only used when viewing video and graphics. Just the screen itself was better, he shows up to 16 million colors, has significantly increased the brightness and viewing angles.
Technology - backlit LCD, size - 4.2 inches, there is a full multitouch (including typing). Comparing the screen with HTC Desire HD, there is an advantage Xperia arc, Super LCD screen Desire duller, less color is natural, especially disappointing viewing angles.


Leader remains iPhone screen 4, resolution and true color maximum, but the difference is minimal. However, see photos (Xperia arc from the top, iPhone 4 bottom): front view comparable to that obviously can be written to the achievement of arc, differ only in viewing angles.






We compare the screens with the HTC Incredible S:


An important point - the technology No air gap, ie the absence of an air layer between the matrix and the protective glass.

New in this there is nothing similar to technology used in the manufacture of Super AMOLED displays the same Samsung Galaxy S.

Due to no air gap reduces the thickness of the screen (as a result - and the whole device), due to the absence of air between the layers increases the brightness, improved reflective properties while in the sun.In general, Reality Display (the so-called screen Xperia arc in the company) - a big step forward compared to its predecessor. Resolution (854h480 points), size, technology used, and the overall impression of quality are different.
LCD-technology, of course, on the set of parameters is inferior IPS (iPhone) and AMOLED (Samsung), but thanks to the above technology gap is not there.


The screen is protected by tempered glass, scratches, he was not afraid.
Design and Dimensions

Appearance - is the setting for which Sony Ericsson Xperia arc fond of almost everything.Arc translated means "arch", the name emphasizes the curved form of the rear surface.
If the previous generation devices posterior surface was slightly convex, then the novelty she almost concave. Bending the minimum, but allowed to reach a record thickness apparatus - only 8.7 mm. Ends the thickness reaches 10.8 mm.

Options are excellent, due to such subtleties phone can be put into any pocket, as the owner of the iPhone 4 minimum fineness is very important to me.

Minimum thickness of the market has the Galaxy S II (8,5 mm), but the difference is small.




Trims two, it's silver color and black-blue gradient.


The latter looks a lot better off, well, first more practical, it does not show fingerprints. Housing, as is the case with the X10, entirely made of plastic, metal elements do not. Side chrome ends (in X10 coverage was very strong, complaints peel was not), so that worry for his safety is not worth it. The back cover is painted metallic paint on the vacuum technology, but that it never ceases to be plastic. Albeit very good looking. Due to all this weight of the unit a minimum, 117 grams.


Р
Dimensions Xperia arc is 125 x 62.5 x 8.7 mm. The size of the display compared to the X10 has increased markedly, the overall dimensions of the case, by contrast, decreased.
