Apple iPhone 4

I have used previous generation iPhones and gotta say this is a real upgrade from the rest.

Having said that, I am going to give an unbiased opinion with my iPhone 4 @ iOS 4.1

Display : Retina display @ 640x960 is just awesome. Have a 3Gs or 3G beside to an iPhone 4 you will notice that Apple really did a great job with the display.

Some shots regarding the Retina Display comparison. Boasting 4X more pixels in the same screen.

Processor : Apple A4 chip. While this uses the same chip with the iPad and with 512MB of RAM there was little or absolutely no lag when running multiple apps or switching between them.

A4 chip - 1Ghz CPU , 512RAM , GPU blablabla. More info at Apple A4 :P

Interface : As usual , the iPhone uses multi touch as the main input system and did a fairly great job with this, and along the way, revolutionizing the phone industry. What the hell is an accelerometer ? Bet you wouldnt know it 3 yrs back before the first iPhone.

Battery : This i gotta say is an extreme disappointment. With conservative usage, I am just able to squeeze out 6hrs of usage and 2 days of standby. Bear in mind the phone condition is as below :

Push Mail and Notifications : Off

Brightness : 30% with Auto ON

3G : Off

Wifi : Off

EDGE : On

Gaming , talk time , surfing on the net , app store time are all included in the 6hrs usage time. This seems fall short of the claimed battery life by Apple. Or did I get a unit with a faulty battery ?
