The Selecao talisman scored a hat-trick at the Fisht Stadium as the Euro 2016 winners salvaged a valuable point against the 2010 world champions.
Ronaldo described his latest treble, the 51st of his career, as a "personal best" but remained focused on the team performance and stressed that the present goal is to reach the knockout stages.
"I'm very happy," the Real Madrid star told BBC Sport. "It is a personal best, one more in my career and the most important thing is to highlight what the team has done.
"We have played one of the favorite teams to win the World Cup, we have been winning twice and drew and I think it was a fair result. The game was about to end and we managed to equalise so we are happy. Now we have to think about the next match, it is going to be hard, but our goal is to win and to move on from the group stage.
"Portugal is going to start moving through the group stage, we know it is going to be hard, and have to think match by match. We are not the favourites so we will try to do our best. The team is doing very well and we are going to do well for sure."
Ronaldo is the first player in history to score in eight consecutive major tournaments in a streak going back to Euro 2004.
