Who else: Nokia 7650 mobile phone Chinese version

With the opening of China Mobile's MMS service, the China version of Nokia 7650 mobile phone appeared in the mainland market as a representative model of MMS. This is undoubtedly exciting news for the vast number of mainland mobile phone players-because many media have introduced the English version of the 7650 mobile phone. From these reports, we have been able to feel the powerful functions of the 7650 and the extraordinary strength of the MMS leader. However, because it is an English version of the mobile phone, the Chinese input and MMS-related functions that mainland players use the most have not been tested. So the focus of our evaluation is these two parts.

Camera: This is one of the proudest devices of the 7650-a 300,000-pixel camera with the highest resolution of 640×480 and 24-bit color. There are three levels of shooting quality to choose from, and three shooting modes to choose from: standard, portrait and night. The final effect of shooting is acceptable, but in the night mode, the camera's framing window will be seriously lagging behind. Portrait photos are most suitable for setting the contact's head, which is very intuitive when making a phone call or looking up the phone book. The photos taken can also be used as pictures in MMS or standby pictures.

Answer state sensor: When the hands-free function of the mobile phone is started, the user only needs to put the mobile phone to his ear again, and the mobile phone will automatically switch from hands-free mode to earpiece mode, which is very intelligent.

Light sensor: automatically senses the light intensity around the mobile phone, and accordingly adjusts the backlight intensity of the mobile phone screen to achieve the purpose of saving electricity and energy.

Voice switch: long press can turn on the voice control function of the mobile phone. The 7650 can record a total of 25 voice commands, which is still a little less for a mobile phone with such a large storage capacity. In addition, you can turn on the hands-free function of the mobile phone through this button when talking.

Speaker sound hole and built-in recording microphone port: 7650 uses 24 chord ringtones, and the maximum ringtone is 72.5dB. Compared with many chord ringtones, this ringtone is inevitably a little smaller, but fortunately, it can be combined with vibration function to strengthen the intensity of incoming call reminder.

Infrared data association: Used for data communication between mobile phones and other devices with infrared data association. If you want to dial-up the Internet with the built-in modem of your mobile phone or access the Internet through GPRS, you should also use this interface.

Headphone interface: used to connect hands-free headphones.

Power button: According to Nokia tradition, this button can also be used to switch between five standby modes, such as standard, mute, conference, outdoor and pager.

Main screen: The main screen size of the 7650 is 34.5mm×4 1mm, and the resolution of the display screen is 176×208, which is quite fine. When inputting short messages, one screen can display five lines of 50 Chinese characters, each line has 10 characters. When displaying short message content, it can reach the display ability of 70 Chinese characters in 7 lines-the shortcoming of Nokia's low display resolution in the past is gone forever on 7650. Because the STN color screen with 4096 colors (12bit) adopts reflective lighting, the brightness is sufficient and uniform, and the viewing angle of the screen is also large. Unfortunately, for the 24-bit 300,000-pixel camera built in the 7650, the performance of the 4096-color screen is still a little weak, and it is inevitable that there will be bad color transition when displaying pictures, but it is not too serious.

Left and right function keys: users can set the most commonly used functions to these two keys according to their own needs.

Five-dimensional navigation key: with the left and right function keys, you can answer the phone, dial the phone book, read short messages, view pictures and even read e-books without opening the keyboard.

Pull-out keyboard: The keyboard design is very simple. In addition to the commonly used keys, there is also a key marked "ABC", which is related to the input method and will not be explained. Yes, when inputting characters, you can easily switch between different input methods through this button.

The SIM card of 7650 is placed in a special way.

Taste function.

7650 is the first mobile phone with Symbian 6. 1 operating system, and its function is naturally not weak. The mobile phone has a very good interface. Each menu has beautiful icons corresponding to it, and the operation is simple and intuitive.

In 7650, the phone book is defined as a card holder, and each record can record multiple items of information. In addition to the default items, you can add information items yourself, and even rename the default information items. In order to test how many pieces of information can be recorded in each business card of 7650, the appraiser made an approximate "crazy" test on 7650-after adding about 60 pieces of information, the appraiser could only "submit" to 7650, and the mobile phone didn't show any intention of holding it, but after reading the contact information for a long time, there were too many things recorded-I believe no user would use it like this. In addition, the 7650 provides a total of 4MB of memory. Excluding the space occupied by the operating system and some necessary files, the total memory available to users exceeds 3,390 KB. Such a large capacity is enough to hold thousands of business cards.

The assessor tested the MMS function of the 7650. Send a multimedia message named "Xinchao Electronic Editorial Department", with a total capacity of 37KB, including a 7650 JPG picture, a paragraph with a size of 7KB and 7 Chinese characters, with a size of14b; ; 7650 recorded sound clip, length 1 min, size 29KB. It takes 80.8 1 s from the beginning of sending to the complete reception of the short message by the mobile phone and prompting to receive it, in which the sending time is about 39.75 seconds and the rate is about 7.45Kbps. Intermediate network delay 13.06 seconds; It takes 28 seconds from sending a mobile phone to indicating receiving a short message, and the rate is about 12. 1 kbps. Because the mobile phone clicks the send button and receives the multimedia message in the background, we can only judge whether there is a change in the icon of data exchange in the GPRS network of the mobile phone, so our test is not particularly accurate and can only provide you with a reference.

It should be noted that the GPRS level of 7650 is level 6 (3+2 channels), and the highest download and upload speeds are 40.2Kbps and 23.8Kbps respectively. However, due to the influence of Chongqing GPRS network where the editorial department is located, the actual rate is much lower than the nominal rate, but the proportion of upload and download rates is similar. It can also be seen that when choosing GPRS mobile phones in the future, in order to really enjoy high speed, the GPRS rating of mobile phones is also a very important data.

Look at the powerful personal information management and entertainment functions of the 7650. Calendars and to-do lists allow users to keep track of their itinerary at any time. Notepad can be used as a memo, and users can also send some e-books to their mobile phones in the form of "". TXT "text to enjoy the fun of e-books when they are free. Of course, if you find an e-book interesting, you can also send it to your friends in the form of MMS or SMS. It should be noted that the SMS of 7650 can support at most 30 messages with 70 Chinese characters, with a total of 2 100 words, so the text with excessive length can only be sent by MMS, but the capacity cannot exceed 100KB. The unit converter of 7650 is relatively complete, which is divided into 1 1 type: currency, area, energy, length, quality, power, pressure, temperature, time, speed, volume, etc. Each of them includes metric and English units commonly used internationally, and there are as many as 40 kinds of currencies. In addition, because the 7650 also supports Kjava, it can download tools, games and other Kjava software through the network, which can infinitely expand the functions and entertainment of the mobile phone. However, the downloaded program will also occupy the memory of the mobile phone, so it is necessary to manage the memory of the mobile phone in time.

Insufficient comments.

Although 7650 has so many outstanding functions, it still can't cover up its shortcomings.

Since its release, the 7650 has received the most criticism because of its huge size. The volume is 1 14.4 mm (length) × 56.3 mm (width) × 25.7 mm (height) when the keyboard is unplugged, and the length of the mobile phone is 157.8mm after the keyboard is unplugged. Perhaps this is nothing to Europeans and Americans with big hands, but for Asians, the volume of 7650 can be described as "huge". Plus the weight of 155 438+0 grams, putting it in your pocket is by no means an easy task. This may be the price paid by the big screen and camera. At the same time, after the keyboard is pulled out, the center of gravity of the mobile phone is relatively high, so pay more attention to the operation when inputting words to prevent the mobile phone from slipping out of your hand.

The memory of the 7650 is 4MB, but it has some reservations about the recording function-it can record at most 1 minute at a time. Although a conversation can be completely recorded by multiple recordings, it is still troublesome to keep an eye on the recording time of the mobile phone at any time. In addition, the 7650 can only use Nokia's Bluetooth headsets, and is not compatible with other brands of Bluetooth headsets.

The battery life of color screen mobile phones has always been a long-standing problem, and 7650 is no exception. The engineering prototype sent for inspection this time is equipped with a 650mAh lithium battery. If it is pure standby, it can be used for 3 ~ 4 days. During this period, occasionally three or five calls have little effect on the use time of mobile phones. However, if you frequently use the camera to take photos, write short messages for a long time, and use GPRS to surf the Internet, the battery will soon run out.

Generally speaking, 7650 is a product with few rivals in the current mobile phone market, but it is "unattainable", and many subsequent products are eyeing the dominance of 7650. In the eyes of mobile phone players, Sony Ericsson P802, which also uses Symbian operating system, is the most competitive product. "You can't rely on the sky, who is ahead", and a wonderful enter the dragon will soon appear in the high-end mobile phone market.
