Review Apple iPhone 4

Here I am at my first speech on what is my attempt to review the latest news from Apple. We are here to talk about the iPhone 4, the device still is populating the entire world market.

The enhancements are a lot of the last iPhone, which is why we are not here to list them all.

Surely the important presence of the PU processor A4 Made in Cupertino. At a frequency of 1GHz can be used in the best way iOS 4 and all of its novelty.
The presence of 512MB of RAM speeds even more iOS 4 and especially through the use of moultitasking app.

One of the new features that was very successful and above all curiosity (even by myself) and FaceTime. FaceTime's built-in 4 a TECHNOLOGY that allows video calls (for the moment only via WiFi) between two iPhone 4.

This technology was possible thanks to the implementation of a front camera. Beyond this there is a camera on the back with a resolution of 5MP with flash LED that allows you to record HD video with a resolution of 720P. Apple has also created in iMovie iPhone version that allows you to create great movies directly onto their iPhone fully exploiting the capabilities of the camera and the iPhone itself. We can create and edit our projects and then exporting them in three different resolutions are including the 720P.


Another of the four main features of the iPhone is the Retina Display, a special display that has a pixel density of 4 times that of the iPhone 3G, well 640 × 960 pixels . In the picture we see the next screen of the iPhone 3G and iPhone 4 in comparison.

This device to be more powerful than its predecessor, is also much more efficient. From that stated at the WWDC in which it was announced the iPhone 4, the battery life has been "enhanced" vis the previous degl'iPhone.

A test conducted by the undersigned will show the performance of the iPhone battery charge in its second cycle (cycle):
We can see that we have a standby time of over 5 days and has been used to about 8 hours. However, specify the use made: in this test I wanted to "squeeze the battery for a longer especially on standby. To do so I turned off 3G, WiFi, location and the cellular data network.
The 8 hours of use have been made with WiFi Active downloading some app from the App Store, snapping photos with geotagging, 21 minutes of talk time and sending many sms.
The result is that the battery actually has a good time but this is an unusual use of the iPhone 4.
If we make an average use, taking an active WiFi often we get such a standby time of about 2 and a half days and shorten the operating time to approximately 6 hours.
Obviously it is clear that the use of 3G and WiFi connection reduced battery life. A council is to conduct a full charge (fully charged and discharged) at least once a month.
We are now at version 4.0.2 of Apple IOS 4, we'll see What does the future iOS 4.1 which most likely will be presented at WWDC on 1 September. Will be fixed some problems such as those relating to the proximity sensor that turns off the display during a call, and other various bugs.
We'll see.
