2010
In January, Ha Jung-eun with her women's doubles partner, Lee Kyung-won, became the semi-finalists in Korea Open Super Series. With Ko Sung-hyun in the mixed event, she only reached the quarter-finals.
In All England, Ha and Ko suffered a first-round defeat to Zheng Bo and Ma Jin of China 17–21 and 12–21. Meanwhile, Ha and Lee, seeded seventh, vanquished Indonesia's Shendy Puspa Irawati and Nitya Krishinda Maheswari in straight sets, 21–18 and 21–18, before bowing out to Chinese third seeds, Cheng Shu and Zhao Yunlei, in the semi-finals.
The next week's tournament in Switzerland brought unsatisfying result for Ha and Ko as they lost to the eventual finalists and their countrymen, Shin Baek-cheol and Yoo Hyun-young, in a tough three-setter, 21–19, 9–21, 19–21. However, in the women's event, Ha and Lee succeeded to their third semi-final of 2010, edging fourth-seeded Petya Nedeltcheva and Anastasia Russkikh out with a 21–17 and 21–11 win. Ha and Lee fought hard in the semi-final but finally lost 21–13, 19–21, and 20–22 to Miyuki Maeda and Satoko Suetsuna of Japan.
Uber Cup 2010
Ha played for the Korean Uber Cup team on May 9–16. She and Lee Kyung-won defeated Yu Yang and Du Jing of China in the final 19–21, 21–14, and 21–19, giving the first Uber cup for Korea.
2011
Ha paired up with Lee Yong-dae again and they won the US Open Grand Prix Gold title in July.
2012
At the 2012 Summer Olympics, Ha and her partner Kim Min-jung, along with Jung Kyung-eun and Kim Ha-na of South Korea, Wang Xiaoli and Yu Yang of China, and Meiliana Jauhari and Greysia Polii of Indonesia were disqualified from the competition for "not using one's best efforts to win a match" and "conducting oneself in a manner that is clearly abusive or detrimental to the sport" following matches the previous evening during which they were accused of trying to lose in order to manipulate the draw. Ha and her partner Kim Min-jung played against Indonesia's Meiliana Jauhari and Greysia Polii. It is suspected that the Koreans emulated China so to avoid playing against another Korean team in the semi-finals; the Korean head coach Sung Han-kook said "Because they don't want to play the semi-final against each other, so we did the same. We didn't want to play the South Korean team again". South Korea filed an appeal to the case, but it was rejected by the Badminton World Federation.
