Li again finished second in the women's team event at the 2015 Southeast Asian Games, beating Hong Kong's Lee Ho Ching in the quarter finals. She was knocked out in the group stages of the women's individual event, having played with a knee injury. Due to her knee injury, Li did not compete for the rest of the 2015, and her next competitive tournament was the 2016 World Team Table Tennis Championships in Kuala Lumpur, Malaysia. That was her last competitive event. In 2017, Li received $55,000 from the Singapore Table Tennis Association as recognition for her achievements.
