"Our tests indicate that the ‘death grip’ issue is real. Overall, though, it’s [iPhone 4] still within the normal performance range for similar products

Apple iPhone 4: ‘Death grip’ problem not as bad on other handsets

Research from PA Consulting Group has been featured across the national and specialist trade press.  PA conducted a series of tests on Apple’s iPhone 4 which indicated that the iPhone4 does indeed suffer from connectivity problems compared to other smartphones. In the majority of the tests PA’s wireless technologists found the iPhone 4’s performance was in the same range as the other smartphones tested but it was consistently at the lower end of that range. And, as found by other testers, when used in the ‘death grip’, the iPhone4’s performance was significantly worse than other smartphones. 

The Daily Telegraph reports on PA’s research and Simon Tonks, who led the testing at PA’s Cambridge Technology Centre, is quoted giving his views on the ‘death grip’: “Our tests indicate that the ‘death grip’ issue is real, and is worse for the Apple iPhone 4 than for other smartphones.

“The iPhone 4’s radio performance was also found to be generally at the lower end. This means it will tend to drop calls earlier than other phones and may suffer more in areas of weak signal. Overall, though, it’s still within the normal performance range for similar products.”   You can read The Daily Telegraph article in full here
