I think *not* moving for all tests (and different types of cellphones to
compare) is near a "best case" scenario for standby time - anyway place some
sensitive radio or the like near the phone, to hear the typical interference
noise when it is sending, just to make sure you don't sit on a "bad spot"
where the phone changes cell every few minutes.
For "best case" talktime scenarios the distance to basestation is much more
important. Here you should check for *very* good RF-signal, means very near
to BS and thus allowing the phone-transmitter to power down to lowest level.
Also note that GSM without simcard is constantly reselecting cells, so energy
consumption is really bad. Switch off GSM when not registering to a network.
