Targeted Evaluation of Sony Ericsson Walkman King W900
Music and shooting have become the most popular functions on mobile phones at present, and many people think that mobile phones must have the above two functions to be worth buying, and they can't wait to concentrate all entertainment functions on mobile phones. Therefore, many smart manufacturers have developed many entertainment mobile phones in response to people's desire for all-in-one psychology. Among them, Sony Ericsson's Walkman mobile phone is the most successful, and the appearance of its first product W800 is like an orange storm sweeping the world. After successfully winning the high-end entertainment mobile phone market, the subsequent W550 pointed to the mid-range, and the heat wave of Walkman mobile phone also intensified. I believe that it is not difficult to find these two mobile phones when you walk on the street. After W800 and W550, facing the increasingly robust 3G network, the Walkman trend of Sony Ericsson finally blew into this emerging market, and the launch of the 3G Walkmann mobile phone W900 made Walkman everywhere.
The appearance of Sony Ericsson W900 aims at shooting top non-intelligent 3G mobile phones for entertainment, including Sharp 903SH. With the title of QVGA screen, 2 megapixel autofocus camera and Walkman, W900 is enough to challenge 903SH. Both of them are so powerful that this fierce battle is bound to be brilliant. However, as the only flagship masterpiece of Sony Ericsson at the end of the year, the attention of W900 was unexpected. So we continue to send you a more detailed and targeted detailed test report of Sony Ericsson W900.
appearance design
The appearance of Sony Ericsson W900 is really shocking. The black body does not use the eye-catching orange on the W800 and W550. The all-black body looks as hard as the Black King Kong. The hard fuselage fully integrates the advantages of many machines in the past, optimizes the overall shape of S700, and incorporates the rear camera design of W800. The black body is not dull at all. The orange WalkMan logo and the decoration of the circular ring make the W900 very fashionable, and completely get rid of the impression that black gives people a stable, honest and dull before.
The body of W900 basically keeps the appearance design of its first rotary mobile phone S700, and has made firm modifications on the rounded shape of S700. The whole body looks slightly rectangular, and the straight lines are more resolute and generous. The style design is quite different from the first two Walkman phones, but it makes people feel similar to the tough style of K750. The black body is painted with piano-grade paint, and the reflective panel looks very gorgeous and upscale. But at the same time, because of the painting of piano paint technology, W900 has become a new generation of "fingerprint king", which is very easy to be contaminated with fingerprints and oil stains, thus affecting the beauty of the fuselage.
Both are Walkman phones, and both are designed with rotating covers. The volume of W900 is 109×24×49mm, which is twice as large as that of W550 and similar to that of Sharp 903sh. It feels very thick in your hand. Tough corners are handled smoothly, which can be well matched with the natural curvature of the palm when held, so that the thick-bottomed fuselage also has an excellent grip feeling. The weight of 148g makes the wide fuselage more textured, but compared with the small and exquisite MM, the W900 is probably a monster. In terms of size, weight and shape, the main target of W900 is the male market.
W900 also has the title of double-sided mobile phone. The camera surrounded by an orange ring on the back of the fuselage looks very prominent. The addition of the orange ring on the black fuselage obviously implies that the W900 has a very powerful shooting function.
The periphery of the fuselage has been well utilized. When the cover is not unscrewed, from top to bottom, there are music playing shortcut keys, the LOCK(hold) key of keyboard locking and the expansion slot of memory stick Duo Pro memory stick. In addition, a rare signal indicator light from Sony Ericsson is added between the expansion slot of the memory stick and the lock key. On the right side of the fuselage are the volume adjustment button, the shooting shutter button and the infrared data association from top to bottom. At the bottom of the fuselage is Fsat-prot data cable, earphone and charger interface. It should be noted that after unscrewing the cover, the buttons around the phone will switch left and right.
Although the rotating design is not the first time in Sony Ericsson mobile phone, the semi-automatic rotating cover design of W900 is the first time. Compared with W550 and S700, it needs to be unscrewed manually all the way, and W900 is very convenient. Just gently push the rotating cover with your fingers to push out the range of the fixed sliding cover of the fuselage, and the sliding cover can automatically rotate to the full open state of 180 degrees, and the length of the fuselage is nearly doubled. The automatic capping process is very natural, without any jam, and can rotate around 180 degrees, which is suitable for users with different grip habits. It should be mentioned that when screwing the cover with one hand, you must hold the lower cover, otherwise there may be an "airplane" phenomenon.
In terms of keyboard, both rotating and sliding mobile phones have their shortcomings, so the W900 is no exception. The separation of function keys and numeric keys requires cross-level operation, which also causes the fatigue of fingers after long-term operation. Because it is a 3G mobile phone, W900 has more buttons for video calling than W550. The wide body makes each key of W900 have a large contact area, and the moderate key stroke and force feedback bring excellent operation feel. Unfortunately, the span is too large, which greatly weakens the comfort of keyboard operation.
Musical effect
Mobile phones with QVGA screen resolution are very rare in Sony Ericsson's GSM network and 3G network. Before W900 appeared, there was only one S700, and the color number was only 65536. Facing more and more mobile phones with QVGA resolution on the market, it is difficult to compete with many mobile phones such as W800, W550 and K750 that only rely on 176×220 pixels. Under the general trend, Sony Ericsson finally used the QVGA resolution screen again on the W900, and the 260,000-color TFT display will trigger a new round of Walkman audio-visual hegemony.
The color reproduction of QVGA display with 260,000 colors is excellent, and the 2.2-inch visual area makes the screen display very delicate, which is one level higher than that of W550. The picture is rich in layers and vivid in colors, but it is smaller than Sharp's top ASV technology screen in visual angle, and the overall display effect is very satisfactory. In terms of screen parameter adjustment options, W900 is different from other models in the past. The menu only provides the adjustment of screen brightness, and the adjustment of screen contrast can only be carried out in engineering debugging mode.
Sony Ericsson's 12 grid menu interface is very beautiful, with many beautiful themes built in for users to change, and more themes can be downloaded through the network. Unfortunately, W550' s rotating cool theme menu interface does not appear in the built-in theme. W900 supports wallpaper and screensaver animation in various formats such as GIF, jpg and BMP. Personalized design is very prominent, which provides great convenience for DIY.
As for the ringtone, the W900 only uses a large-caliber independent speaker, which is placed on the back of the fuselage. Compared with the three stereo speakers of the W550, the W900 is much eclipsed.
At this point, the sound quality of W900 with large-caliber speakers is very good and the volume is very high, which saves a lot of face for single speakers and avoids losing to W550. W900 has no sound interruption at the maximum volume, and the sound reproduction is also ideal. In addition to the loud volume, W900 has quite good penetration ability, and it can easily hear the ringing of incoming calls in noisy outdoor, which can effectively avoid the phenomenon of missing calls. W900 supports MIDI, MP3, AMR and other mainstream ringtone formats. The support of ringtone formats such as MP3 provides great help for setting personalized ringtones. In terms of SMS prompt tone, W550 also supports the setting of customized SMS prompt tone, which can directly set MP3 files on the fuselage as ringtones or SMS prompt tones, which is very convenient in sound setting.
Shooting special
As for the camera, the W900 uses the same camera as the W800, and the 2-megapixel CMOS camera also has an autofocus module, which is supported by a selfie mirror and a high-light flash, which brings great convenience for shooting. It should be pointed out that W900 can only shoot when the cover is closed, and cannot shoot when the cover is open.
After closing the upper cover, in standby mode, press and hold the shutter button to activate the shooting menu option. The menu design is basically the same as that of W800, which integrates the operation interface of Sony Cyber-shot series digital cameras and adopts the autofocus lens module. Therefore, the shutter button of the semi-focusing type also appears on the W900. The 2-megapixel camera can take photos of the largest 1632× 1224 pixels. In addition, users can choose 640×480 and 160× 120 pixels to shoot.
In shooting mode, the W900 provides a wealth of options. The newly added spot metering option makes the exposure better and more accurate, and supports four modes: normal shooting, panoramic shooting, photo frame and continuous shooting. In terms of color special effects, four special effects are provided: black and white, negative film, sun exposure and exposure. According to different shooting environments, W900 also provides five precise white balance modes: automatic, daytime, cloudy, fluorescent and incandescent. In terms of photo shooting quality, it provides two choices: ordinary and fine, and supports night shooting, flash activation and self-timer delay operation. In addition, the W900 also provides macro shooting options because of its support for focus mode, but users need to pay attention to the camera's focus mode, otherwise it will be difficult to take clear photos.
W900 not only supports the shooting function of still photos, but also supports the sending of multimedia messages and even unlimited audio and video recording. The recording time depends on the remaining storage capacity. In the video shooting mode, users can also choose the mode and special effects in the camera function, which provides the support of QVGA(320×240) pixels for the maximum resolution of video shooting. Switching between photo and video shooting state is also very simple. When the mobile phone is held horizontally, it can be quickly switched by grasping the up and down arrow keys, and the operation and use are very simple.
Because the W900 supports 3G network, a camera dedicated to video phone is provided beside the receiver. Because it is only provided for videophones, the requirements for pixels are not high. However, W900 still provides it with a variety of options. Here, the appraisers, like all the audience, are eager to quickly open the domestic 3G network and use the satisfactory 3G videophone.
Because the camera with the same parameters as W800 is used, and its function is very similar, through the detailed comparison of appraisers, it is found that its imaging quality and function are consistent with those of W800 and K750, and it is not necessary to do in-depth and detailed tests. Please refer to the camera evaluation project of K750 for detailed test.
utility function
W900 continues the editing style of Sony Ericsson. The conversion between input language (you can also press the # key for a long time) and input method (you can also press the * key for a long time) can be realized by the right soft key, and pressing the * key can input punctuation and characters. In terms of overall response speed, due to the influence of resolution, the overall response is slow, but much faster than S700. The phenomenon of pause and suspended animation did not appear, but there was a slight delay and the overall speed was acceptable. In terms of short message storage, it can also meet the storage capacity of 500 short messages, and the current daily application can fully meet the current needs of users.
When editing MMS, W900 can add pictures, ringtones, photos, movies, videos, recordings and other files to the machine at will, activate the camera to shoot once, and set the display interval of each page at will. The background of the MMS page also provides a variety of colors to choose from, and users can edit unique MMS. The body does not limit the capacity of MMS, but users should know the MMS sending capacity limited by operators when using it. The storage capacity of MMS is shared with the body memory, so users can store a large number of wonderful MMS.
As for the phone book, W900 provides 1000 storage capacity, and each contact can store five phone contents, including seven options, such as email and web address, incoming call picture, personalized ringtone, voice command, position and company, and information. When viewing comment contacts, you can quickly view information by moving the joystick left or right. Where the cursor moves, the default phone number of the contact will be displayed immediately. By moving the joystick left and right, all the telephone contents can be displayed one by one, which is quite convenient to query.
Entertainment expansion
In terms of memory, the W900 has a built-in 470M memory, and it also supports the expansion of the memory stick Duo Pro memory stick, which can support up to 2G expansion. Whether it is built in or expanded from the fuselage, it has truly realized massive data storage. Compared with the 240M memory of its W550, the W900 not only improves the memory of the fuselage, but also expands the memory card. It is the mobile phone with the largest memory on the market at present, which provides great support for the Walkman function. Even without memory, 470M of memory is enough for ordinary daily applications.
Due to the built-in large-capacity memory, in order to facilitate data transmission, W900 comes with a USB cable with Fastport interface, which can be used as a mobile disk and a card reader after being connected to a computer and equipped with a driver. In addition to the data line, W900 provides infrared and Bluetooth connection in wireless expansion, and the comprehensive wireless interface brings great convenience for data exchange and transmission. Its Bluetooth port adopts the latest 2.0 standard. Because there is no Bluetooth 2.0 adapter in the market, when the Bluetooth adapter with 1.2 standard is used for data transmission test, its speed is maintained at about 40K, and the data transmission process is very stable without abnormal interruption. I believe that the speed will be doubled when using the Bluetooth 2.0 adapter. W900 is backward compatible with GPRS network connection, and WAP websites can be accessed quickly through the built-in WAP web browser. In addition to WAP websites, our appraisers also found that as long as the relevant parameter options are set, we can also access the World Wide Web of WWW. With the built-in PLAYNOW function, you can also connect with official website to download genuine music and related files such as themes and desktop wallpaper.
As the world's first 3G mobile phone with Walkman logo, W900, like the two Walkman mobile phones of G network, can enjoy MP3 songs without turning on the mobile phone function. Every time the phone is turned off, a startup menu will appear, asking the user whether to start the phone function or directly enter the music playback function to enjoy music. The built-in multimedia player can recognize and play MP3 files well. In terms of playback function, W900 and W550 are basically the same. Please check the related WALKMAN function test of W800 for detailed functions.
W900 is equipped with the support of wire control, which provides great convenience for outdoor operation. It should be pointed out that the remote controller of W900 can't display words, but only provides support for displaying numbers. Wire control provides music selection for MP3 playback function, and simple previous and next songs can meet people's needs. The adjustment of the 45-level volume is more humanized than the certificate of the fuselage. In the MP3 playback state, the line controller only displays a constantly rotating picture, and does not display songs and the like. In the process of answering, if there is an incoming call, the line control can only display the word incoming call, and there is no incoming call display. In addition, as we all know, the remote control of W900 is highly targeted and can only be used on ourselves, but it is not universal for W800 and W550.
There is a switch on the remote control of W900. When pressed, the phone will automatically switch from MP3 state to FM radio. There is no radio activation option in the menu because the remote control supports the switching of FM radio. You must use the remote control to start the radio. Wire control provides a 3.5mm standard stereo headphone interface, equipped with the same in-ear headphones as W800, and its performance in sound quality is basically the same as W800. Users can also use other better headphones to listen. In terms of the function of multimedia player, W900 provides the option of enhancing stereo, which is equivalent to the 3D sound effect of ordinary MP3 player. When this function is turned on, sound stage suddenly turns on, and the sound effect of the original headphones has been greatly improved.
In addition to the powerful WALKMAN function, W900 also provides good entertainment performance, supports the extension of JAVA MIDP2.0, and has built-in NVIDIA's brand-new GoForce 4800 3D graphics processing chip. According to its powerful 3D processing ability, two of the three games built in W900 are 3D games, which have very high visual effects and playability. Another note-taking game is similar to Tetris, which matches the music theme of W900.
In the process of JAVA performance testing, we used the authoritative JAVA testing software JBenchmark for testing. From the test results, JBenchmark and JBenchmark2 are weaker than W550 and W800 in 2D plane performance test, but this is normal because of the influence of screen display resolution. In JBenchmark3D software specially designed for 3D performance testing, the performance of W900 is three times higher than that of models such as W800 and W550, and the 3D performance is very good. At present, any large 3D JAVA game can be run at will.
The functions of music DJ, video DJ and photo DJ also appear on the W900. As for the functions of the three, I won't say much. You can refer to the detailed evaluation of K750. In addition, in terms of application software, W900 also provides a music learning software, which provides key demonstrations of scales and chords of pianos and guitars, and also provides instructions for beginners of music to use the beat, giving full play to the functions of its music mobile phone.
W550 has built-in alarm clock, calendar, tasks, post-it notes, countdown timer, stopwatch, lamp, calculator, code memo, etc. It provides great convenience for daily use and going out.
Summary evaluation
As for the battery, the W900 adopts BST-33 battery with a battery capacity of 900 mAh. In the test of standby time, the mobile phone can continue to work for about 55 hours after continuously talking at 1 hour, sending and receiving 20 short messages and 10 multimedia messages, but it can continue to work for 30 minutes after continuously talking, sending and receiving 10 short messages and 5 multimedia messages. Under the test of playing pure music, W900 can maintain the playing time of about 28 hours, which is very close to the nominal 30 hours. Excluding the processor energy consumption caused by MP3 music compression ratio, the playing time is basically the same as the nominal. The mobile phone can last about 13 hours when the function is turned on, which makes people feel very satisfied with the playing time, especially some professional MP3 players W900.
Sony Ericsson W900 appears in 3G network with a brand-new attitude. The appearance of Sony Ericsson's second QVGA display resolution model has attracted many people's attention. Walkman and 2 million autofocus cameras are the highlights of W900. Although the powerful shooting function W900 of Sharp 903SH is slightly inferior, the screen is not as good as Sharp. However, its walkman function and Sony Ericsson's brand appeal are unique. Rigid semi-automatic rotating fuselage, professional LCD wire control, NVIDIA GoForce 4800 3D graphics processing chip and built-in massive memory of 470MB have also become the sharp weapon of W900, so as long as it falls back to a suitable price, W900 will have a very good market.
