iPhone 4 - In depth, opinions and analysis


Apple and Steve Jobs once again give the best of themselves with the presentation of the iPhone 4, without the G , as some expected. Apple's new phone breaks into the smartphone market at a sensitive time for Apple , whose market share is threatened by high-end smartphones with Android operating system , such as Google's Nexus One or Motorola Milestone . Apple announces a terminal with up to 100 new features . Let's see which are the most important.


Design and display

The iPhone 4 is relatively similar in form factor to the iPhone 3GS . In fact, the size of the screen is the same (3.5 inches) and also that of the outer case. The design, however, is 24% thinner than the iPhone 3GS , at just 9.3mm thin . That makes the iPhone 4 the thinnest smartphone on the market , at least for now.

The entire front of the phone is covered with tempered glass . Sides and back are made of aluminum and stainless steel to increase the terminal's resistance to bumps and scratches. It should be noted that the housing also serves as an antenna, an interesting detail that saves space inside to embed more technology.

Although the same size as that of the iPhone 3GS , the iPhone 4 screen comes with a novelty: a technology called Retina Display that raises the density of pixels per inch to 326, four times the number of pixels of the old model and that gives the screen a unique sharpness . The name is due, in fact, to 300 pixels per inch is the maximum density that the human eye is able to perceive at a distance of 3 or 4 centimeters . The resolution of the Retina Display is 640 × 960 pixels .

Externally, the iPhone 4 features external buttons, volume, mute, dedicated button for the front camera, microSIM card slot, 3.5mm jack audio input, and rear camera with integrated LED Flash . Of course, the front features the single menu button that characterizes all iPhones .


Connections, camera and plugins

The iPhone 4 is not missing the G for any reason. The terminal will not be, as claimed in some blogs, compatible with the new 4G LTE networks . The phone's connectivity is limited to HSDPA, Wi-Fi N, Bluetooth, and A-GPS , which is no small feat.

In terms of camera , the new iPhone 4 does not intend to enter a futile war for megapixels. The camera of the new terminal only has 5 megapixels . However, Apple has focused on improving everything possible quality images and video and, indeed, the difference with snapshots of the 3GS is very palpable. The iPhone 4 camera has an LED flash, 5X digital zoom and touch focus . The camera also records 720p HD video at 30 frames per second . In addition, the iPhone 4 will have a specific version of the iMovie software installed , which will allow a high degree of video editing.

In addition to the camera, iPhone 4 incorporates a bulky battery of sensors including gyro, accelerometer, proximity sensor and ambient light . Of all of them, the gyroscope is the most relevant. Not only is it the first sensor of its kind in a mobile , but it also allows the iPhone 4 to position itself in six axes of movement (the traditional accelerometer only has 3 axes). This new sensor opens new doors to video game controls or more precise positioning in GPS mode.

The image section has earned a "One More Thing" and Steve Jobs has presented a feature that no iPhone had before: a secondary camera for video calls . The application that moves it is called Face Time and it seems to run quite agilely.


Memory, processor and software

Another of the most outstanding elements of the iPhone 4 is its processor . It is the same A4 1Ghz chip that Apple integrated into the iPad and that equates the iPhone 4 with terminals equipped with a Qualcomm Snapdragon processor , with the added attraction that being developed by Apple, its operation is fully optimized for the system. iPhone OS operating . In terms of memory , the iPhone 4 will be available in two models of 16 and 32 GB.

The operating system is also new. It is the iPhone OS 4.0, which now changes its name to IOS4 . The new software supports true multitasking and allows you to organize your desktop in folders among many other functions. The new operating system will also allow you to read e-books on the iPhone 4 thanks to the iBook integration . In fact, iBook becomes an integrated platform for all Apple devices , making it possible to synchronize notes or new eBooks between various devices.


Autonomy and availability

Of all the components of the iPhone 4 , the battery is the largest in size . According to Apple , the autonomy of the terminal has risen by 40%, which allows, in theory, 10 hours of WiFi browsing or watching videos, or 6 hours of 3G browsing. The autonomy in standby is 300 nominal hours.

The iPhone 4 will be released in the United States associated with the operator At & T. Its price will be 199 euros for the 16GB model and 299 for the 32GB model , both with a stay of 24 months . The price of the terminal, free , will be 799 euros . Spain is on the list of countries where the iPhone 4 will arrive in July . At the moment, yes, there is no data on at what price or with which operators it will go on sale .


The best

The screen , the processor , the gyroscope and the new IOS4 operating system with multitasking , all washed down with a very reasonable price, promise to make the iPhone 4 a new best seller.

It can improve

The insertion of a MicroSD memory card slot would have been convenient , especially considering its multimedia capabilities.
