To follow up, the second phone call hung up after 3 hours and 54 minutes 
-- only a two minute saving, but the Freerunner's battry icon still 
showed lots of power available, instead of being completely drained like 
my test with power saving turned off.

Since the call ended about the same amount of time as my test last night 
(236 minutes vs 234 minutes), I'm curious if either AT&T or TMobile 
simply kill a phone call just shy of 4 hours of talk time to free up 
their network.

To solve that riddle, I'll try both my AT&T SIM card and TMobile SIM 
card in the Freerunner and call it from my Vonage VoIP line, see if I 
can narrow down what killed the call.

My speculation at this point is that the 3 hour 52 minute call last 
night that drained my battery might not have drained the Freerunner's 
battery completely, but that the phone just ran out of power at some 
point after the phone call because power saving was turned off.

Stay tuned,
Ian Douglas
