Here's the exhaustive guide to all the features of the new iPhone 4.
Hardware technical features
It has an Apple A4 chip inside, just like the iPad. Inside the A4 there are a few interconnected chips: A Cortex-A8 main processor unit—the main brains—paired with a PowerVR SGX 535—which handles the high definition graphics of the new iPhone. These are directly connected with each other and two low-power 128MB DDR SDRAM chips. Since all these components are in the same chip, they can process things faster while consuming less battery than before.
The A4 also consumes less power because its sub-components can be switched on and off when they are not needed, shaving watts whenever it's possible.
The battery is 16% bigger than the current one. Coupled with the A4 processor and new display, it results in a longer battery life: Apple claims 40% more talk time. Here are their figures:
• Talk over 3G: 7 hours.
• Browsing over 3G: 6 hours.
• Browsing over Wi-Fi: 10 hours.
• Video: 10 hours.
• Music: 40 hours.
• Stand-by: 300 hours.
The 3.5-inch screen has a resolution of 960 × 640 pixels. Apple calls is the Retina Display, and it has four times as many pixels as the current iPhone 3GS' display. The screen has 326 pixel per inch resolution, a higher definition than your typical magazine, a quality that shows in the screenshot.
The main camera
The new iPhone has a bigger sensor for the main camera, with bigger lenses. This one is capable of capturing high definition video at 720p 30 frames per second. The sensor maintains the same 5 megapixel count, but it increases the size of the sensor, so it has a higher ISO. That means that you would be able to take better photos and video in low light conditions.
The camera also has a LED-based flash, which works both for photographs and video.
The video conferencing camera
In the front, there's a video conference camera, with standard VGA resolution. This camera will be used with third-party applications, as well as Apple's own video conference solution.
The new iPhone 4 has a gyroscope built-in. This means that it can track movement with a very high precision, much higher than the built-in accelerometers in the previous iPhones. It's 3-axis, so it's capable of detecting pitch, roll, and yaw. Couple with the accelerometer, you have 6-axis motion sensing.
• Like the iPad 3GS, the new iPhone uses the new micro-SIM standard.
• It has an additional microphone on the top used for noise cancellation.
