iPhone 4 Reception Issues: Detailed Analysis
AnandTech then ran many tests to find out the signal degradation by holding an iPhone 4,
in their hand in 5 different positions. They observed the following:
Inside a case, the iPhone 4 performs slightly better than the Nexus One. However, attenuation gets measurably worse depending how you hold the phone. Squeezing it really tightly, you can drop as much as 24 dBm. Holding it naturally, I measured an average of 20 dBm.
The drop in signal from (more…)
