Posted by

Apple just launched iphone 4 at World-Wide Developers’ Conference. Apple claims that the iPhone 4 offers over 100 new features, though he would focus on only a handful for the keynote and the Thinnest smartphone on the planet.

The iPhone 4 runs on the A4 processor, Apple processor improved power management, that iPhone 4 will a 40% improvement in battery life due to the efficiency of the A4 (plus the 16% larger battery). so the device can also play up to 10 hours of video, 40 hours of music, and should have an standby time of up to 300 hours. In addition to GPS, a compass and accelerometers, the iPhone 4G is adding a gyroscope, providing full pitch/roll/yaw sensing in 3D space.

The iPhone 4 will feature a 5 megapixel camera with a backside-illuminated sensor, which Jobs says increases the amount of light captured by the sensor, resulting in better photographs, particularly in low-light situations. The camera will also record HD video at 720p resolution and 30 frames per second, and the LED flash can be used to light video as well. New iPhone 4 also has a new high resolution display that doubles the pixels in each direction (960 x 640) for a 4X overall pixel count increase. The result is a 3.5-inch display with a native resolution of 960 by 640 pixels that is actually a higher resolution than the typical human eye is capable of perceiving, when held at a distance of just 10 to 12 inches. Apple calls it a “Retina Display. It’s rated at 326ppi, which Apple claims is beyond the human eye’s limit of distinction. The retina display is one whose resolution meets or exceeds the maximum resolution the human retina is capable of resolving, assuming perfect vision. The LCD IPS display (In-Plane Switching) used in the iPhone 4 is manufactured by LG.

The iPhone 4 smartphone will also support 802.11n Wi-Fi, assisted GPS, Bluetooth, and packs and accelerometer, compass, proximity sensor, and an ambient light sensor,. Thedevice also sports a gyroscope, which enables six-axis motion sensing…just like a game controller, and iPhone OS 4 will offer developer APIs to leverage the gyroscope: Jobs envisions the gyroscope enabling whole new types of mobile gaming.

The new design is more squared off, with a flatter back, creating a stronger shape in both your hand and eye. The iPhone 4 smartphone has stainless steel casing, all-glass front, and a design Jobs describes as the thinnest smartphone on the planet. the frame on iPhone 4 has same corners and front-facing camera mount as the lost iPhone. Also, construction of the screen connector is slightly bigger which confirms an increase in the number of connections to the motherboard, as a result there clearly will be more pixels than the current-gen models.

The iPhone 4 with retina display will be available June 24 in black or white, with pricing set at $199 for a 16 GB model and $299 for a 32 GB model: those price points match the iPhone 3GS. Initial availability will be the United States, France, Germany, Japan, and the United Kingdom.
