Your choice. I'm not familair with the Ipaq ( I'm lurking for general ARM stuff ) but I would take the battery out side and connect again with a wire. In the wire goes the ampere meter. We are talking _milli_ ampere. The battery charging circuit will drawn relative much current. ( "there is no harm, the wall out let is an infinit powersupply" ) Measuring current from the battery is simply the best place.
