Apple IPhone 4  Details

 

The retina screen

The iPhone 4 Retina display is the highest resolution screen we have seen on a mobile phone. Retina is just a trade name from Apple to distinguish it. But you do not need extra differentiation because it’s one of the best screens we’ve seen.

The new screen is the same size as previous iPhones (3.5 inches), but the resolution has been increased four times. In previous generations, the new screen of the iPhone 4 with 320 x 480 pixels has the incredible resolution of 640 x 960 pixels. Due to the increased pixel density (which reaches 326 pixels per inch), the images now look much sharper (or softer, if you will) than before.

Based on an IPS panel, such as the high-end desktop screens, the iPhone’s new LCD screen has a LED backlight and a contrast ratio of 800: 1, 4 times more than the previous ones.

In fact, things seem as impressive as on paper. The capacitive screen for iPhone 4 of 16 million colors offers excellent picture quality. The colors are bright, the blacks are deep and the readability of the sunlight is remarkable. The viewing angles are also excellent, comparable to the results of the Samsung Super AMOLED displays. In terms of tactile sensitivity, it is also excellent. Of course, multitouch support is back.

Cameras and battery

The iPhone 4 has a 5-megapixel rear-view camera that delivers sufficiently sharp images with sufficient light with its f / 2.8 aperture. The camera has LED flash and video recording with 720p. The camera app offers touch, geotagging and panning modes. The front camera is VGA, which makes simple pictures and needs a lot of light to take the best pictures. The front camera also shoots videos, but at 480p. The phone is powered by a Li-Po 1420 mAh battery.
Connectivity and other features
The only mobile phone with micro-SIM enables 3G mobile data, Wi-Fi 802.11 b / g / n, Bluetooth 2.1 with other Bluetooth enabled devices, GPS for A-GPS navigation and a micro USB 2.0 port for charging of the phone

connectivity

One of the most promising features of the iPhone 3.0 operating system has been to allow third-party developers to create applications that communicate with accessories or devices via USB or Bluetooth. We did not see much results, but we benefited from the new iPhone.

On iPhone 4, Bluetooth v2.1 with A2DP is enabled to stream music to Bluetooth-enabled stereo headphones or headphones. Bluetooth file transfers are not available. Point-to-point connections over Wi-Fi and even Bluetooth are one way to avoid this, but they only work on iPhones. Bluetooth connectivity also includes support for Bluetooth keyboards, just like the Apple iPad.

The latest iPhone 4 is compatible with Wi-Fi b / g / n standards. Although we did not have a Wi-Fi N router for testing, we can confirm that the Wi-Fi connection over a G-connection is much faster than the iPhone 3G, and when you press the palm against it the iPhone 4 Wi-Fi antenna – the metal strip on the top left side of the phone – it is even amplified by the signal. This is exactly the opposite of the problem we have with the cellular signal.
