1. A method of performing a formation pressure test, comprising:
inserting a bottom hole assembly (“BHA”) into a wellbore from the earth's surface to a first location within the wellbore through a subterranean formation, wherein the BHA comprises:
a drill bit; and
a formation testing tool comprising a battery configured to power the formation testing tool during a formation pressure test;
performing an initial formation pressure test with the formation testing tool;
determining, using a processor, drawdown parameters for a drawdown phase of a planned formation pressure test using parameters and results of the initial formation pressure test, wherein the planned formation pressure test comprises the drawdown phase and a buildup phase;
performing at least a portion of the planned formation pressure test with the formation testing tool while powering the formation testing tool with the battery only while not circulating fluid in the wellbore; and
determining, using a processor, at least one characteristic of the formation based on results of the planned formation pressure test.
