What exactly do you mean? Talk time is usually a measure of how long the phone battery lasts, measured in terms of how many minutes of talking you can do before the battery dies.
If you want your phone to last longer there are usaully better quality after market batteries you can buy.
I am sorry for the confiusion. I wish to make out going calls of just one minuter. as soon as the time reaches to one minute it should automatically get disconnected. it is cell phone's buit in capability in most of the models. but I donot know how to access it. it does not have to do any thing with the battery of my cell phone.
