This total cost was estimated after the prices of each component were recorded individually. These prices were in turn taken from the manufacturer of those components. However, this total estimated cost doesn’t include other charges like- Apple’s development costs, shipping charges, advertising costs etc.

One thing that came out from this cost analysis was that the iPhone 4’s priciest part is its ‘Retina Display’. It is said to be developed by LG at the cost of $28.50 which is 15.2% of the total cost. This retina display which is 3.5 inch thick and boasts of a 960 by 640 resolution hasn’t been used in any other electronic product till date. In fact, it is being marketed as display with a higher resolution than even a human eye!

The pixel density is much higher than 1080p which speaks a lot about the quality and clarity of picture on your mobile screen. There is also a protective layer on the touch screen which is scratch resistant and maintains the vivid color display.

The next costliest part on iPhone 4 after retina display is NAND flash memory, produced by Samsung and priced at 27. Its 14% of the total cost!

Some other iPhone 4 components and their prices
•4G bits of mobile Double Data Rate (DDR) SDRAM-cost $13.80-developed by Samsung
•baseband integrated circuit, cost $11.72
•A4 processor-cost-$5.80
•Gyro scoping chip-cost $2.60

Heated Body
It has been experienced by certain users that due to iPhone 4 radio, the phone starts heating up after some time. Since the outer back of the phone is done up in glass, the heat can be felt more clearly. However, with a firmware update this issue can be resolved!

Terrible Reception
This is what can be defined as the ‘death grip’. It means losing the reception or signal when the antenna gets accidentally covered by your hand. This has been seen in several phones. But the basic problem with iPhone 4 is that it doesn’t boast of a great reception to start with.

Battery Run Out
The iPhone 4 battery usage time is 6 hours 14 minutes which is quite impressive on paper! The battery burns itself out just after 13 hours of moderate usage! This issue too has been seen in previous phones like SPRINT HTC EVO 4G and iPhone 3GS.

Screwed Up Screen!
There have been some reports about seeing yellow spots on the screen display of iPhone 4. Apple has indeed taken the innovative path with the use of 3.5-inch, 960-by-640 IPS LCD screen [no other electronic product is using this specification]. But the yellow spots on iPhone 4’s screen display are indeed a reality too which needs to be checked!

Wobbly Proximity Sensor
The proximity sensor of iPhone 4 becomes a bit wobbly especially when you restore the phone from a back up of an earlier iPhone. The phone hangs up in the middle of calls due to this proximity sensor issue. It can be resolved by setting your iPhone 4 as a new phone in iTunes!

These five possible bugs in iPhone 4 may or may not survive as it all depends on Apple’s innovation and technology!
