Swapping batteries during an important call is not really an option "please hold, i will call you in a bit", sometimes even, "wait a sec i just need to find my charger" is not an option either during the call. for me extended battery seems more convinient.
and if your accu is empty within a call, you should change your way using your phone.
that is not quite true!!! when a person is swallowed by work, quite interesting kind of work, the person only notices battery level when he checks the time!! - "oh no its late evening already!! oh no i still havent done arrangements for the nite!! oh no the battery is uber low!!"
manufacturers shall change the way they cut costs on stock batteries and develope us an ultimate engineering solution.
I have to admit that when I travel I carry 3 spare batteries! 2 "normal" capacity and 1 "high" capacity (and the extended back to go with it). As I can go for 36 hours between leaving and getting to a hotel to recharge and may be using the GPS a lot I need to know I have power at hand. Even back in the "old" Nokia N80 days I use to carry at least 1 spare battery. I agree that modern smart phones aren't very smart when it comes with battery performance but you do get a lot of performance compared to the "good old days". The ability to swap out batteries is for me essential though and one of the many reasons I wouldn't buy an iPhone. This is something that I think HTC have forgotten with the new "One" and Samsung could win out with the S3 because of this.
My advice - buy some cheap ebay batteries and cycle them in your phone.
