With the files, users can organize their applications in collections by simply sliding one application to another. In addition, it is also possible to customize their screen release and hospitality with a choice of wallpapers already provided or any photo of their phone.
As every year, Apple has taken the habit to bestow upon us his new iPhone to c? Heart of the summer. The fourth model is the most radically in contrast with his predecessors. For better?

The output of each new iPhone has become a global event. The Apple smartphone has become such a star he invites himself even in the newspapers of 20h. iPhone 4 was no exception to the rule, especially with the leak, he began to make a specialized websites several months ago. But the product is it all hype? For this new iPhone, Apple has not done things by half as we criticized him for the launch of 3G. In addition to the design review in depth, especially the technical evolving on almost all points.



The first thing that stands out is the screen Retina Display which measures 3.5 inches but still enjoys a resolution four times greater than that of 3G with 960 x 640 pixels! The processor is also revised upwards as it is now the famous Apple A4 processor running at 1 GHz and supported by 512 MB of memory (RAM). Multimedia side, the sensor autofocus camera now offers 5 megapixels and receives support from an LED flash. The video capture is also clearly improved since the iPhone 4 can record video in HD resolution of 1280 x 720 pixels (720p). And like every year with Apple, smartphone, new operating system. So we find in this iOS4 iPhone 4. Phone side, the iPhone 4 carries two microphones for such analysis and filter out background noise.

As for autonomy, the battery is a little bigger now with 1420 mAh. It is not much more than for 3G, but Apple promises a 40% gain autonomy. We will see what it is later in the test. All this is in a very compact size of 115 x 58.6 x 9.3 mm. Note that the device found in version 16 and 32 GB As with previous models, there is no port for a possible memory card.

Pack contents

The smartphone comes in an ultra compact package that includes:
• charger
• A USB cable
• A wired stereo headset
• The manual
Appearance and Design

The first thing that strikes with the new iPhone, it is obviously brand new design. Unlike usual where complete information about each new iPhone are jealously guarded, this iPhone 4 has seen many leaks and photos have been circulating around the web several months before its release. Most people, including us, was his design quite risky, if not downright ugly. Yet the iPhone 4 is certainly the most beautiful of all the iPhone, and even one of the most beautiful phones ever released.



Seen in photo is one thing but the take over is another. If the front does not fundamentally change, it offers a look somewhat more angular, a little more industrial, with more pronounced edges.



The gray outline of the device is made of brushed steel, for superb. The operation continues with the charm of the hull coating that is actually glass! Attention, we are talking about an ultra-resistant glass that wants thirty times stronger than plastic. The back of the unit is not rounded, but now appears straight. In fact it is so smooth that even difficult to distinguish the front of the rear when the unit is in the pocket. The materials used are of high quality and give lots of character to the iPhone 4 looks like a true small luxury item, like an expensive watch, for example. Especially since the whole is perfectly finished and assembled.



The design seems to apply to men and women, at least for the black version. The white is more mixed. Apple has managed a tour de force arrived to squeeze all the components of its new iPhone in just 9.3 mm thick. The manufacturer claims that the smartphone is the end of the world. A little research tells us that this boast is perfectly justified. So far, the thinnest smartphones showed 9.9 mm. So even if a cat's whiskers, the iPhone 4 is the finest moment with the 9.3 mm. Which makes the smartphone well as end of the world right now!



The unit is still stingy with buttons. It offers the same as its predecessors, namely the buttons to adjust the volume, the key facial "home" and that to turn on and off the smartphone.



The connectors are the same as before, namely a 3.5 mm mini jack connector and a connector for charging and syncing Apple iPhone. We would have appreciated the appearance of a button to take pictures!



As iPad 3G, iPhone 4 SIM cards are not accepted but only the classic microSIM. If for some reason you insist on bringing your old SIM card in, you will have to engage in a session of cutting a bit nerve-wracking!

OS & Ergonomics

Known as the iPhone OS since its inception, the mobile operating system from Apple is renowned iOS4 sees, certainly because it is now also operating system of the iPad. The latest update, which of course is that found immediately in the iPhone 4, has brought its share of novelties.



Starting with the multi-tasking! This new feature, long awaited, is handled automatically by the OS. When you quit an application, it will pause in the background. To return, double-click the center button shows you all the apps in court. Note that developers must update their applications to make them compatible with multitasking. Since the release of the OS a month ago, many publishers have already updated their applications. This really changes the use of the iPhone very positively. Now you can be fully part of a game, get a phone call, then resume your game at the point where you left off. Applications in the background are frozen and do not consume energy. The rare application that runs natively in the background in earlier versions of the OS (voice, GPS, audio,?) Do not change operation. The memory management is automatic. When an application needs a lot of memory, iOS4 close by itself some of the applications running in descending order of memory usage. You can still close them manually, by holding down one of them and pressing the small sign at the top right icon that appears.



Another important novelty of the iOS4: records! Long been available for jailbroken iPhones, the ability to create folders lands in this new version of the operating system. You can now create folders that can contain up to 12 applications. To create a folder, simply switch the arrangement of icons and drag an icon over another. This will create a folder whose name will default to that of the category in which the apps are the majority in this case. You can also create and rename them from iTunes.



The application "Mail" is also changing as it can now find the emails of your various addresses in a unified mailbox. Mail allows you to view, in one place, all your different email accounts. Another interesting new feature of Mail: The application can now handle the son of discussion: all messages on a subject can be gathered under the last message.



Research also is expanding since Apple has improved Spotlight. You can now search through it in the history of your SMS but also directly launch a web search on Wikipedia and from the Spotlight window.



iOS4 also brings a host of other new smaller but still significant enough as iBooks, the ability to focus with your finger on the videos, the "coup d '? it in mail", etc..

We would still like to see an area of ​​the home page that provide quick access to certain settings for Bluetooth, Wi-Fi, a "discreet", etc.. as is the case on most competing OS. Notification of delivery of SMS / MMS is still not on the agenda either. Bouygues Telecom offers a good solution is to insert a code at the beginning of the message, but it is only tinkering.

However, despite these criticisms and even if iOS4 is still not perfect, he dusts off brilliantly the OS of the iPhone. The latter began to acknowledge his age to compete and he is exhilarated with animations discreet but welcome and funds. Especially because the navigation is still in its intuitive menus and responsiveness is still required.
Multimedia features (Camera / Video)

If there is one point on which the iPhone has always been derided by its critics, it is that its photo sensor. Apple wanted to react with the iPhone 4. Of course, this does not seem really obvious at first. On paper, the photo sensor autofocus of the four iPhone is indeed not much better off than its predecessor, from 3.2 to 5 megapixels. This may seem little compared to what has sometimes competition. However, despite the arms race of Sony Ericsson, Nokia, Samsung and others, the megapixel never guarantees a good quality photo. The lens is essential for correct hope take pictures and 5 megapixel (2592 x 1944 pixels) are largely sufficient for most purposes, as long as you do not make very large enlargements of your photos.



From this point of view, Apple has been careful to give his latest one of the best sensors we had ever seen on a 5-megapixel. The manufacturer has also added autofocus and an LED flash, which now allows the photos in low-light environments. In light environment, this smartphone takes great pictures. Respect of colors, finesse of contours, level of detail satisfactory ... all conditions are met. Even the photos of moving subjects do not suffer from blurring, which is an improvement over the sacred sensor 3GS. You can make the development of a fingertip on the screen. The quality is deteriorating course when you try to take photos in dark environment. In fact, the pictures are good enough in low light as you are shooting stationary subjects. But at the slightest shake, blurring is guaranteed even if the subject is close and even flash. But this detail did not you cool! The function of the iPhone 4 is really a very nice surprise!



And if catching photo is clearly improved, the video screen literally die! The iPhone 4 can save them in a HD resolution of 1280 x 720 pixels (720p). The rendering is excellent, the videos filmed combining a good level of detail and fluidity with flawless 30 frames / second. As the brightness is good, the videos you capture with the iPhone are really excellent.

Caution, however, the radius of the defects, note that it is for the photo or video, the sensor is not comfortable with high-contrast scenes and poorly managed, often leaving too much light filter, which the effect of overexposing the result of your catch. Similarly, if the interface of imaging features is praised for its simplicity, it lacks all the same settings. Thus, one can not choose the resolution at which you want to capture for example.



One last point: the iPhone 4 embeds a camera for facial Facetime (see elsewhere). This camera can also capture photos and videos in VGA resolution (640 x 480 pixels).
Other features (MP3 player, WiFi, Bluetooth?)

Before turning to the multimedia functions itself, let's talk about the screen. Although it has not changed size, the screen is certainly the element that has the most dramatic improvements. It measures 3.5 inches but still sees its resolution four times, now displaying 960 x 640 pixels! Baptized? Retina Display?, This display is the one who shows the most pixels per inch in the world with 326 dpi (dots per inch)! Beyond the numbers, the rendering is excellent, both in terms of brightness, contrast or black level. The display is extremely late! While the new screens are Samsung Super AMOLED steal the title of "most beautiful mobile screen in the world" on the nose and beard of the four iPhone, its screen Retina Display nevertheless absolutely exceptional. And that quite logically that the multimedia content to enjoy.



Photo Viewer, simply called "Photo" by Apple, does not change much but the few new features are welcome. There is the emergence of new tabs marked "faces" and "card". As you can see, we can now view photos by face or on a map, if this information is filled course. For faces, it is necessary that you use iPhoto on a Mac and you have made a face recognition previously. For display on the map, we need your photos geotagged silks. It's very easy on the iPhone since it is sufficient to allow the smartphone to do it once for you is automatically. Finally, the display of a photo is much better on this screen than on the 3G example. 4 The iPhone makes it possible to display a clearer image for the same zoom level.



Side "iPod", the changes are not lining up at the gate. The music player does not change position but also to better customize your playlists as you can now create or edit them directly from the mobile, which is very significant and gives the impression of being less than totally chained to iTunes even if it is still largely the case. The sound reproduction is excellent. Note the appearance of shortcut keys for the music player in the multi-tasking manager. To get there, go left once you've double-clicked on "Home".



For video, no change in the interface or features. However, the iPhone turns 4 that can play HD video, that is to say, 720p (1280 x 720 pixels)! The rendering is really beautiful on the screen as long as the video is encoded correctly. However, still no DivX / Xvid on the menu. Note that if you're willing to spend a little money, full of iTunes video content so paid. The Apple platform can even rent movies recently. You can view them from the iPhone too.

Unlike many other competing smartphones, the consultation of all the multimedia features are exceptionally fluid, even when you advance in HD video.



The web browser is faithful to itself, that is one of the best currently available on mobile phones. It is not surprising the lack of Flash technology to the extent that Apple is viscerally opposed in its mobile devices (iPhone, iPad). Depending on your browsing habits, this lack may go completely unnoticed or limit yourself to stay. For you to see if the absence is damaging or not depending on the sites you frequent.



You may have noticed the appearance of a camera facial in this new iPhone. What is it exactly? But to make the video course! Not just any video, of course, since this is FaceTime, a video to Apple sauce you've probably discovered through the many pubs on the spots on one now hears on TV. The video has never been as successful as he predicted the operators to launch 3G but it is obviously more to cool Apple. However, if the manufacturer seems to want to reinvent the video, it gave itself the means with FaceTime, which could be described as high-end service. It offers a much higher quality video services to current but suffers from two weaknesses. On the one hand it needs to be connected via Wi-Fi to work and secondly you can only call to another iPhone 4. In short, Facetime is currently very limited. Apple told us to work to expand its compatibility to call in Facetime to computers for example.



Finally, now talk about a latest development, which should show its full potential in the coming months: the gyroscope. You already know the accelerometer that allows the smartphone to detect if it is leaning to the right or left. Well aware that the gyroscope is almost the same, but 360 °! To simplify to the maximum, say it allows the iPhone 4 detect how it is moved in space. The best example of the use that is made will certainly play Eliminate: GunRange. If you move the iPhone in one direction, the game also moves in that direction!
Conclusion

Impossible to conclude this test without a word about the reception problems suffered by the iPhone 4. Although this problem has been identified in the early hours of marketing the product, it has been publicized in recent days, the media grabbed the TV info. But what exactly? The antenna which can receive the signal system of the iPhone 4 is located at the bottom left of the hull, while that for the Wi-Fi and Bluetooth is at the top right. If you hold the camera with your palm resting on the bottom left, the network signal bars drop more. It is therefore problematic for those who hold their mobile in the left hand when they call. This applies to most left-handed but also many who have grown accustomed to hold their mobile in the left hand when they call, probably to keep the right hand free. But in reality, this reception problem becomes really annoying in areas of poor reception. To remedy this, Apple decided to make a commercial gesture by offering their Bumper cover or until the end of September in the first place. This allows the hand and smartphone not to be in direct contact and this eliminates the well-known reception problems! We also strongly recommend the Bumper Apple. In addition to eliminating the problem of reception, this accessory protects the turn of the device by raising slightly the edges of the front and rear. In fact, it prevents the screen is in direct contact in case you fall flat. We find quite effective, aesthetically rather successful, but really expensive at 29 euros. So now that Apple supply, Bumper really serve as great accessory!



In terms of mobile phone functions, autonomy has also been revised upwards and Apple announced a battery 40% faster. It is always difficult to judge the battery life with a smartphone since the duration of a load depends on the use of each. But know that we could verify the gain of 40% compared to 3G. Thus, during a normal day of use (+ voice mail + music + some games + a + little video mail), when the lower house to 18h 3G, the iPhone holds up to 4 23h! The improvement is substantial and real! If you go directly to an iPhone 3G the new iPhone, you will end up in heaven. Side conversation, the sound quality is really go. The iPhone integrates four because two microphones, one used to your voice and the other is used to analyze the sound environment in order to better eliminate noise.

At the choice is logical that those who have fallen under the spell of the first iPhone are sure to get one that is logically more beautiful, more powerful and more comprehensive than its predecessors, but the real question is: do those who have remained impervious to the attractions of the far smartphone at the apple should fall for this model? Yes? and no! It is certainly a response to Normand, but much depends on what you expect from a smartphone. In fact, with advances in photo and video, the new multitasking OS, the screen unconventional, self-improvement and all other improvements, Apple has blurred many of the shortcomings of previous models. The only thing that can now appear very prohibitive for some are required to go through iTunes. But for the rest, while the iPhone 3G was exceeded in many ways by its new competitors, the iPhone 4 delivers the record straight. Apple is the king of the smartphone and has the means to stay!
