Also, for the not-as-technically included, dB for RF measurements is a 10 log scale. Meaning a change of 3 dB is a HALVING of value. Going from 9 dB to 24 dB means you lost 97% of your signal strength.

For the not-as-technically included (sic), dB attenuation is relative to a signal, not an absolute measurement. A higher dB attenuation doesn't necessarily mean a lower signal if you are starting with a higher signal strength in the first place.

So the iPhone has a higher signal strength? Do you have anything showing its signal strength vs that of other devices?

For clarification purposes -- in the above, were you specifically addressing and discussing the output signal strength from the iPhone's transmitter section or the received input rf signal strength to the iPhone's receiver section?
