The iphone 4 features far more functionality than the iphone 3GS, with hundreds of upgrades, many more than previously expected.　　In his keynote address, Mr. Jobs highlighted 8 major improvements, including a new design, a revolutionary Retina display screen, a 3-axis gyroscope, a A4 processor, and a new camera system. Systems and software upgrades to the iphone 4 include ibooks Store introduction, iOS4 loading, and IADs ad system and FaceTime video call capabilities. It also brings new surprises on the price.　　In addition, battery performance, 802.11n wireless network support, enterprise enhancements are very strong, the iphone 4 to the user's surprise is far from so simple, the following comprehensive analysis of the iphone 4 of the top ten features of the analysis: first, the new design 9.3 mm Global thinnest smart phones the world's thinnest smartphone　　The 1th of the iphone 4 's new design, the iphone 4 thickness of 9.3 millimeters, has thinned by 24% compared to the iphone's 3gs12.3 millimeter, making the iphone 40% the world's thinnest smartphone.　　Double mic design As is rumored to be the case, the iphone 4 is added to the dual mic design, one of which can play an active role in noise reduction, which will greatly improve the quality of the iphone 4 call. Cleverly designed antennas The iphone 4 can be so thin that one of the winning points is that the iphone 4 integrates the antenna and the border of the handset, and the side stainless steel frame antenna is divided into two segments, serving as two antennas.　　One side is responsible for Bluetooth, WiFi and GPS signal reception, the other side is responsible for UMTS and GSM mobile phone signal reception, this design is very wonderful. In addition, the IPhone 4 button style is also a new design.　　The front and rear panels of the IPhone 4 use a special tempered glass, which is 30 times times the hardness of the plastic, so it is very resistant to strokes. Two, far beyond the industry's Retina display technology The second revolutionary feature promotion of the iphone 4 is the real-world technology called retina, which is the most commonly guessed argument, and the iphone 4 uses the 960x640 pixel resolution display screen,　　The equivalent of 78% pixels on the ipad screen. Because the screen size doesn't change, or 3.5 inches, the resolution improves the iphone 4 display resolution to the iphone Four times times the 3GS.　　　　The size of 326 pixels per inch, this resolution is very alarming, familiar to the realistic resolution of the user will know, usually our computer display screen resolution of 72dpi,iphone 4 of the resolution of the computer 3 times times more, so the display will be very delicate.　　That's why jobs says Retina display technology is much better than OLED.　　In addition, the IPhone 4 display screen resolution reached a high contrast of 800:1, while adding the IPs wide visual angle technology, which was used in Apple ipad.　　With a number of upgrades, the IPhone 4 has surpassed the previous generation and is well above the industry level. Third, A4 processor standby Video Call 10 hours for the first time on the ipad A4 processor, now officially landed on the iphone 4, but in WWDC2010 's keynote address, Jobs did not specifically highlight the A4 processor high-performance, rose to not disclose the iphone 4 using the A4 processor frequency,　　But the battery power of the iphone 4 is particularly stressed. Jobs released the iphone 4 battery for 7-hour 3G calls, 10-hour video playback, 40-hour music playback, and 300-hour standby. In addition to 3G calls, the 7-hour call is 2 hours longer than the iphone 3GS 5 hours, and no significant increase in other endurance time.　　However, after joining the A4 processor, the energy performance does not decline, has been a progress.　　Wireless network support before the rumor of the CDMA version of the iphone 4 did not appear, the iphone 4 now supports UMTS/GSM/GPRS network, while supporting the network support dual-frequency Hsdpa/hsupa 3.5G base, the highest download speed can be achieved. 8Mbps.　　In addition, the IPhone 4 supports the latest 802.11n wireless standard.　　Four-axis Gyroscope will subvert the gaming experience many of the IPhone 4 enhancements to the hardware are upgraded on a previous basis, with only three-axis gyroscopes being newly added hardware. Three-axis gyroscope, as the name implies is a mobile phone can be induced three dimensions of the direction of change.　　The mobile phone's ability to sense the motion will be greatly enhanced, for the use of gravity-induced games, the user experience will have a very large impact, the operation will feel more close to the real feelings. In addition to the three-axis gyroscope, the iphone 4 also has the following sensors, is also very powerful: 1, built-in compass, this is the IPhone 3GS added new features 2, close proximity induction call can automatically turn off the screen 3, automatic light sensor screen can automatically sense the ambient light adjustment brightness 4, gravity accelerometer feel gravity Speed up five, 5 million photo support 720P HD video Shoot the iphone 4 's photo enhancements are unprecedented, from iphone 3GS 300 millionPixel elevation to 5 million pixel, also supports AF.　　The IPhone 4 also has 5 times times digital zoom and built-in led dimming. But the biggest upgrade in the iphone 4 performance is in video shooting, which supports high-definition video shooting with 720P resolution, with a frame speed of 30FPS. At the time of filming, the IPhone 4 also supports touch-focus, plus a key sharing feature.　　　　According to Jobs, the IPhone 4 uses an imaging element called backside illuminated sensor (back-irradiation sensor), which can also be greatly improved in imaging. After the video shoot was enhanced, Apple ported imovie's excellent video processing software to iOS, making it easy to edit video on the iphone. When you edit a video, you can insert any video and audio.　　As a result, the IPhone 4 has become a powerful video-shooting device, and the multimedia upgrade is a big one.　　Vi. iOS4 Introduction of the revolutionary multitasking iphone OS4 landing iphone 4 is the least of the suspense, but there are some small changes, mainly in two: the first is the IPhone OS 4 officially renamed the iOS 4,iphone system has a brand new name.　　2nd, iOS4 of the iphone 4 has tweaked the search engine, adding Bing and Yahoo searches, plus Google, which now has three different search engines on the iphone 4, and users are free to choose.　　Apple's approach seems to be distancing itself from Google, which, for now, has become the biggest competitor to iOS. iphone OS 4 renamed to iOS 4, feature upgrades we have mentioned in the previous iphone OS 4.0 release, mainly in a number of ways: 1, a revolutionary multitasking processing iOS can listen to music, download, while the Internet, email.　　But in Jobs ' speech we also found a detail where the iphone 3GS and iphone 4 opened a Web page, and the iphone 3GS was turned on, and the iphone 4 was opened in half.　　2. Another important upgrade of IOS 4 is that it supports folder archive management of programs, and users can drag several software into a folder of custom names to manage. 3, iOS4 Mail Management when there is a unified Inbox 4, IOS4 has better data protection 5, iOS 4 support multiple Exchange account landing, while supporting Exchange Serve2010 6, iOS 4 support SSL VPN network connection in the introduction of iOS 4, job Also announced anotherData, if combined with the iphone, ipod Touch and the ipad's total sales, the 100 millionth iOS device will now be sold soon. The ibooks store, with its massive books, ibooks with the ipad and is now officially in the iphone 4.　　While the iphone 4 introduced ibooks, ibooks also had a significant upgrade in functionality. 1, first of all, one of the biggest upgrades, Apple will be in ipads, ipod Touch, iphone ibooks fully through.　　If you buy a book on your iphone, the book can sync to your ipad or the ipod Touch book store, and you don't have to pay for it.　　2, the IPhone 4 inside the ibooks not only can read the books purchased online, but also can read PDF documents, take notes, while the bookmark system also has upgrades.　　3, ibooks can synchronize the user's location and bookmark information.　　IBooks, the App Store and itunes have become Apple's three largest online stores, with another data line published by Jobs showing that the total number of registered users in three online stores has exceeded 150 million. Eight, after the IADs advertising system, which makes developers more profitable, launched the IADs ad system on the ipad, Apple also announced that IADs landed on the iphone 4.　　This upgrade is a great thing for developers in the App Store, but it has a certain impact on the user experience for mobile phone users.　　Focus on graphic effects and interactivity Apple launched the IADs mobile phone advertising system to emphasize the visual effects and interactivity, the general IADs will be shown in the lower part of the screen, click to view Interactive online ads. Mr. Jobs said all iads devices would be added to iOS 4 devices in July.　　With the development of the IADs system, Apple has invested more than 60 million dollars, aiming to occupy 48 of the mobile advertising market. Nine, FaceTime as long as there is WiFi can be video call after the introduction of the top eight upgrade, Jobs bought a look at the iphone 4 to introduce the last killer application, that is, video calls.　　Apple's name for this feature is face time, which is quite different from the video call we talked about earlier.　　Apple FaceTime currently supports WiFi only, meaning that two iphone 4 handsets can make video calls without any setup if they are in a WiFi-usable environment. Moreover, the video call can choose Scenery, portrait and other different scene patterns.　　At present, Apple's FaceTime function is limited to WiFi environment, not in the operator network environment, is expected to 2010 years will be implemented through the operator network video calls.
