The 25-year-old, who was mentored by Tulisa, faced Union J in the sing-off.
She delivered a heartfelt rendition of White Flag by Dido, while Union J sang Perfect by Pink.
Three judges opted to save the boyband.
Jade said: "To me it's just been an amazing experience; I thank you guys for all your critique and my life starts from today."
Tulisa joined her act on stage and said "maybe" she should have "pulled some more ballads out of the bag for Jade".
She said: "We took a risk together and I apologise if it is my fault."
Jade was criticised for her song choice on Saturday night, after she sang and danced to Sugababes' Freak Like Me on the Halloween-themed live show.
After the sing-off, tearful judge Louis Walsh was the first to announce his vote for Union J.
He said: "I'm the mentor for Union J, I love them and I don't want to lose them, I have to send Jade home."
Tulisa quickly voted to save her act. Then Nicole Scherzinger favoured Union J.
Nicole said: "Jade, you are a beautiful, beautiful young woman, you are a strong young woman who has been through so much. You are one of my favourite voices in the competition.
"With a tone like that I know no matter what happens you're going to get a record deal because you are a recording artist.
"Union J, through your performance and through your work you have proven yourself to me so the act that I have to send home, I'm sorry, is Jade."
Gary Barlow said Union J's performances so far had been "good" but not "exceptional".
He said: "I'm excited though to know what's coming next for you guys. I can see the commitment; I can see the ambition in your eyes."
He said Jade was a "phenomenal vocalist" but wondered if he "wanted it" more for her than she did and therefore decided to send her home.
Lucy Spraggan automatically went through to next week's Number One hits themed show after being unable to perform due to illness.
Sunday's results show marked the return of Robbie Williams on the X Factor stage.
The 38-year-old pop star sang his new single, Candy, and declared his support for controversial act Rylan Clark during his energetic performance.
He also treated Louis to a lapdance, in a move which left the judges gobsmacked and reminded viewers of an audition by X Factor reject and Britney Spears lookalike Lorna Bliss.
Next week's results show will feature performances from Rita Ora and No Doubt.
