Booker, with a 3-pointer less than two minutes into the game, passed Kobe Bryant to move into fourth place on the NBA scoring list of players before their 21st birthday. Booker, with 2,774 career points, trails Carmelo Anthony, Kevin Durant and leader LeBron James.
Tyler Ulis added 20 points and 10 assists for the Suns.
The Mavericks rested starters Dirk Nowitzki, Nerlens Noel and Wesley Matthews in the second half. Yogi Ferrell and Dwight Powell led Dallas with 21 points each. They have lost four straight.
The Suns moved to 24-57 and will finish with either the second- or third-worst record in the NBA. The Los Angeles Lakers started Sunday 24-55.
Phoenix turned a three-point halftime lead into a 104-85 lead after three quarters, with Ulis scoring 15 points in the third.
Rookie Derrick Jones Jr. highlighted the fourth with a rebound dunk with 8:55 to play. Jones scored 15 points.
The Suns used a 17-0 run to go up 24-14 with 5:50 left in the first quarter. The Mavericks went through a stretch of eight straight missed shots.
Warren's corner 3 with one second left in the first gave Phoenix a 40-29 lead, part of his 15 points in the opening 12 minutes.
The Suns led by as many as 16 points in the second quarter, only to see Dallas take a 56-55 lead on Nowitzki's 12-foot turnaround at the 4:55 mark. But Phoenix took a 68-65 lead into the break.
Booker had 12 of his 17 first-half points in the second quarter.
Suns forward Marquese Chriss limped off the court with 8:06 to play in the third quarter after a Dallas player banged into his right knee. Chriss went the bench and ice was applied to the knee, and the injury was announced as a deep bruise.
Chriss finished with nine points in 17 minutes.
