What's interesting is that most other top phones (EVO, Nexus One, etc) don't have metal in the cases = no problems. Except the Nexus One does have this problem

Except the Nexus One does have this problem (to the tune of 17 dB of signal loss, according to Anandtech).
- jonknee 16y agoHolding naturally, Anandtech measured the iPhone 4 losing 19.8 dB vs the Nexus One 10.7 dB. Keep in mind that dB is logarithmic, so the iPhone 4 performs ~10x worse than the Nexus One in that test. http://www.anandtech.com/show/3794/the-iphone-4-review/2 http://www.anandtech.com/show/3794/the-iphone-4-review/2
- sounddust 16y agoThe reason that signal strength is measured in dB in the first place is because it corresponds linearly to actual performance based on distance. It is originally derived from the measurement of a signal needed to sustain an audible sound across X miles of telephone wire. Therefore, it's a bit disingenuous to base performance on the linear strength of the signal.
- varjag 16y agoExcept that mobile phones are wireless and are subject to inverse square law as far as signal is concerned. Signal theory traditionally operates with log scale because it simplifies math greatly and makes graphs manageable. If you say have noise floor at -30dB, expressing it on a linear graph is not very convenient.
