Outperforms naked iPhone in total power (dBm).

Neowin has learnt that Apple’s bumper case for iPhone 4 not only restricts signal loss but also improves antenna performance.

The above test shows that a bumper cased iPhone 4 gains 28 dBm in Tot. Rad. Pwr. across all three benchmarks and outperforms the naked iPhone. The margin maybe small but it is a little consolation for users suffering from the ‘death-grip’.
