Live radio shows, print photo shoot and live television shows
Contrary to previous seasons, the competition was split into three stages: the live radio shows, print photo shoot and live television shows. The change in the competition format was to give all finalists an opportunity to gain exposure on radio, print and television. In another change to the format of previous years, all finalists are required to perform songs performed or composed by homegrown talents for the entire competition to showcase and promote local music. The Revival round, a round where singers perform to reinstate them from the competition, did not return this season.

The live radio shows started on 3 January 2013 and ended on 31 January 2013. The performance shows were held via Y.E.S. 93.3FM. Each week, three finalists performed on the first four weeks, with the voting lines opening before the performances. The results were based solely on the public votes. The results were announced on week five, with the contestant receiving the most public votes awarded with "鲜声夺人奖" sponsored by Tic Tac. The top three contestants based on judges' score were also announced, though the scores has no impact towards the overall results.

Guest judging role was brought in during the live radio shows. Y.E.S. 93.3FM radio personality Nico Chua was brought in as the guest judge.

The voting for print photo shoot started on 28 January 2013 and ended on 13 February 2013. Prior to the voting window, all finalists went through a full makeover by stylists from I-Weekly. Individual photos of finalists that were taken during the photo shoot were then uploaded to I-Weekly's Facebook page. Public votes, I-Weekly editorial team votes and Facebook photo likes, constituted 50%, 40% and 10% of the final results, respectively. The result was announced on 16 February 2013, during a meet-and-greet session at Alexandra Retail Centre; the singer with the highest combined total was awarded "最i上镜奖".

The live television shows started on 18 February 2013 and ended 31 March 2013. As with previous seasons, each live show had a different theme. Each week, the contestants perform on Monday at 8:00 pm or Sunday at 8:30 pm (live final), with the voting lines opening before the performances. The results are announced immediately after the performance shows at 9:00 pm, with the contestants in the bottom two or the one with the lower combined total being announced and eliminated. For the top 12 performance shows, judges' score, public votes and scores accumulated from the live radio shows and print photo shoot, constituted 50%, 30%, 15% and 5% of the combined total, respectively. For top 8, top 6 and top 5 performance shows, judges' score constituted 70% of the combined total and the remaining 30% were determined by the public votes and gift-to-votes from the official website. Judges' score and public votes with gift-to-votes from the official website constituted 50% each to the combined total of the final.

The live television shows often featured guest performances. The first live television show included performance from Taiwanese girl group Popu Lady. There was no guest performer on the second live television show and footage from the audition rounds were shown instead.
