iPhone 5 Overheats with A5 Chip, May Delay Launch?
Apple is rushing to get the iPhone 5 to customers in Q3 but is running into problems. A Chinese site Sohu, citing no sources, has claimed that the iPhone 5 is delayed because A5 processor is overheating in the iPhone 5.
It seems that the real problem is within the software and A5 chip is nothing to do with it. This fact could be corroborated with the pair of reports appeared last week, where iPad was overheating after installing iOS 5 Beta and reached to a temperature of 65 degrees centigrade despite being turned off. In another report, developer’s iPhone 4 USB cable caught fire after installing iOS 5 beta and finally singed-off.
It is worth noting that A5 is present in iPad 2 too and does not dissipate enormous heat and that the chip was successfully tested within iPhone 4 by Apple team only raises question to this story. Certainly this claim has moved the needle from “if” to “when”. However, for me, the iPhone 5 delay rumor stands on shakier ground.
The report adds that next year Apple will transition to a 28-nanometer manufacturing process with the A6 chip as compared to Samsung’s 45-nanometer mfg process used in A5 chip. The author further speculates that the iPhone 4S (not iPhone 5) will keep users busy until Apple’s hardware engineers find a solution to overheating problems.
