Does Google G1 generates more data traffic than others?
By both running tcpdump on G1 and collecting data on the GPRS gateway, it shows that the Android OS itself only generates a little data traffic. It really depends on what apps and services running on top of the OS.
If we go further to lower level to observe the radio stack:
logcat -b radio -v long
There is no evidence showing additional data traffic or stack overhead from Android OS. Actually the GSM driver and the RIL depend on the OEM, mostly Qualcomm and HTC.
Some side results during the research for further reading:
1. *#*#7262626#*#* on G1 will run a HTC app called field test, which shows network information, will try to find the meanings of these parameters later.
2. It also available for some HTC WM phones.
3. A look at PDP Context in UMTS networks
