The 35-year-old England captain endured a poor tournament, scoring just 87 runs across eight innings. His struggles mirrored a challenging batting display overall, even as the England cricket team progressed to the semi-finals.
Their campaign ultimately ended at the hands of the India national cricket team, who were both co-hosts and eventual champions.
Widely regarded as one of the top white-ball batsmen, Buttler has refused to draw any firm conclusions about his future based on the tournament alone, confirming he has not made any retirement decisions and remains committed to representing England.
Looking ahead, Buttler is set to feature for the Gujarat Titans in the Indian Premier League. Before that, however, he plans to take time away in France with his family, hoping the break will allow him to reset and return reinvigorated for the challenges ahead.
"Obviously I had a poor tournament, which is disappointing," Buttler said on his For the Love of Cricket podcast with former England fast bowler Stuart Broad.
"But I have been playing some of the best cricket of my (career) in recent years, so hopefully I can get back to playing my best.
"I certainly have ambitions (to play for England again), but no longer being a captain, I am not a selector and whatever, so what will be, will be."
He added: "Obviously the tournament didn't go personally how I would have liked it to go, and I just felt like I needed some space from cricket and not to think about the game, and I could not have been further away from cricket where I was in that week."
England coach Brendon McCullum has said that they are "leaning towards" dropping captain Ben Stokes down the batting order ahead of the Test series against New Zealand that starts on Thursday.
Joe Root has paid tribute to Sachin Tendulkar while closing in on the all-time Test run-scoring record, insisting that being mentioned alongside the Indian legend is an achievement in itself.
England have ushered in a new era for their Test side by recalling Ollie Robinson, dropping Zak Crawley and handing maiden call-ups to Emilio Gay, James Rew and Sonny Baker for next month's first Test against New Zealand at Lord's.
At 41, Samit Patel has brought the curtain down on a legendary English domestic career, a decision accelerated by an ECB ruling that rendered him ineligible for county competition.
