Critical reception
The song was well received by critics. Billboard stated "The end of 2016 is near, but there’s still tons of new music to look forward to before it comes to a close. LeToya Luckett will return from a musical hiatus with her long-awaited new single “Back2Life” hitting iTunes this week. The single’s exclusive artwork features Luckett sporting cropped blond hair, a black leather choker, and fierce cat-eye liner." Rap-Up stated in a review "LeToya Luckett is “Back.” Following a hiatus from music, the former Destiny’s Child songstress unleashes her new single, “Back 2 Life,” off her upcoming album Until Then. Sampling Soul II Soul’s classic “Back to Life,” LeToya sings about a failing relationship. While the muse for the track is unknown, it could be inspired by art imitating life." Singersroom described the track as a "mid-tempo, laid-back groove," while SheBOPS noted that the song's "sombre R&B sounds sonically pinpoint the vulnerable realities of a painfully toxic relationship."
The music video is over eight minutes long, the music video begins with LeToya in a perfect relationship. The plot twists when she suspects that her significant other is a little too friendly with his female best friend. The video ends with a heated argument between LeToya and her man, resulting in her leaving the relationship with a "to be continued...".
Reception
Amber McKynzie from The Boombox wrote "It’s a new year, which means it’s time to be out with the old and in with the new; or simply take some time to focus on you. At least that’s the mindset LeToya Luckett follows in her new video, 'Back 2 Life.' LeToya Luckett recounts a love story gone wrong thanks to a good “friend” named Cynthia. First in love and floating through the honeymoon stage, Luckett discovers the man she thought she knew is nothing like the man she met after meeting his childhood friend who’s a little too close for comfort." Lauren Porter from Essence commented: "Ladies, we've all been there: you're dating a great guy who wants you to meet his female friend who you suspect wants to be more than that. Well, in LeToya Luckett's new video for her song, "Back 2 Life" art truly imitates reality with a scenario we can all say we've encountered at least once or twice. With some steamy eye-candy from Being Mary Jane's former "cuddy buddy," Thomas Q. Jones, Luckett and her on-screen love serve up a true cautionary tale for what it means when he says, 'don't worry baby, she's just my friend.'"
