iPhone 4 Cracked Glass Cases Almost Double iPhone 3GS'

When the iPhone 4 was revealed, it was obvious that its design was more fragile than the previous generation. If you double the glass panes, the accidental shattering rate will increase too. Now there is data to confirm this theory.

According to consumer electronics warranty company SquareTrade, 3.9 per cent of all iPhone 4 owners have reported a cracked screen - meaning the front and the back glass panes - within the first four months. On the iPhone 3GS, this percentage was only 2.1 per cent.

The data also shows that 82 per cent of all iPhone 4 accidents involve shattering glass, compared to 76 per cent of the iPhone:

The company says that "at least a quarter of the broken glass claims involved the back screen". I was expecting an even distribution, but this could be easily explained by the fact that many people use iPhone jackets to protect the back of their devices.

But while they conclude that "the iPhone 4 is significantly more prone to physical damage than its predecessor" and its "aluminosilicate glass seem to crack at least as often as the old glass", they couldn't find any connection between cracked backs and cases.

The total percentage of accidents per unit has increased too, from the 2.8 per cent of the iPhone 3GS to the 4.7 per cent of the iPhone 4. That's almost 70 per cent.

The company says that, while the increase is very significant, the accidental damage rate is still remarkably low compared to other smartphones models analysed in 2008. They claim they will update their report with data from Android phones in the future. [Square Trade via MacRumors]
