Poco F9 Ultra Review: Bose-Tuned Sound and a Bigger Battery in a More Refined Body
The Poco F9 Ultra builds on the F8 Ultra's sound-first formula with a Bose-tuned speaker system, a 6.9-inch 1.5K AMOLED display, an 8,050mAh battery, and a more sophisticated design that trades denim-inspired novelty for metallic composure.
The Poco F9 Ultra arrives as the company's most confident attempt yet to turn its sound-first strategy into a lasting identity, pairing a Bose-tuned speaker system with a larger battery and a more restrained design. The phone builds directly on the Poco F8 Ultra, which first introduced Bose-tuned audio to the lineup and changed how the device felt in daily use. Where the F8 Ultra felt like a turning point, the F9 Ultra reads as an effort to make that direction stick.
The audio experience remains the centerpiece. The Bose-tuned speaker system delivers the same punchy, room-filling sound that distinguished its predecessor, giving games more impact, films more depth, and everyday listening a sense of presence that most phones still treat as an afterthought. Poco has not treated the Bose partnership as a one-off flourish. Instead, the company appears to be building on it with more confidence, wrapping the sound-first approach in a package that feels bigger, more polished, and more ambitious.
The design marks a clear shift in tone. The denim-inspired rear panel of the F8 Ultra is gone, replaced by a finish that feels more metallic and architectural. The silhouette is simpler, with cleaner lines and flatter surfaces, but it does not come across as plain. The camera island remains a large rectangular module across the top, housing three cameras and an LED flash in a neat 2 by 2 arrangement, with the speaker grille set off to the right. New to the F9 Ultra is a dynamic light ring around the speaker grille that supports personalized visual effects for incoming calls, games, and music. The effect is closer to a clean white LED accent than anything flashy, a subtle nod to the brand's gaming-phone roots without overwhelming the more sophisticated direction.
Two color options tell slightly different stories. The Dark Cherry finish is the more expressive choice, bringing warmth and a bit of drama without tipping into flashiness. The Black version feels more understated and technical, with a red side-button accent adding a small but effective point of contrast.
That more polished look comes with a more substantial physical presence. At 235 grams, the F9 Ultra is about 15 grams heavier than the F8 Ultra, and the extra weight is immediately noticeable, especially in one-handed use. Its dimensions of 163.49 x 77.94 x 8.74mm are broadly in line with its predecessor, so the overall footprint will feel familiar to anyone coming from the older model. It remains a wide phone, and the curved edges help soften the grip without making it a truly one-handed device. The matte finish feels premium, pleasant to touch, and better at disguising smudges than a glossier surface. Button placement and the in-display fingerprint scanner are unchanged, making the F9 Ultra feel less like a phone you need to relearn and more like one you simply need to get used to carrying.
Performance is a refinement rather than a leap. The F9 Ultra runs on Qualcomm's Snapdragon 8 Elite Gen 5, the same flagship platform used in the F8 Ultra, and Poco has retained the VisionBoost D8, a dedicated chip aimed at improving gaming and video performance. The result is a device that feels like an evolution of an already capable formula rather than a raw power upgrade.
The display supports that entertainment focus. A 6.9-inch 1.5K AMOLED panel is large, sharp, and vibrant, with a refresh rate that gives the phone a clear edge in games that can take advantage of it. The same smoothness carries over into scrolling, animations, and general navigation. Brightness is another strength: Poco says this is the first global lineup to use the new M11 luminescent material, helping the panel reach up to 4,500 nits in peak brightness.
The 8,050mAh battery is among the largest in its class, reinforcing the phone's entertainment-first positioning. The ultrawide camera, however, still does not feel especially wide, leaving room for improvement in a system that otherwise leans heavily on its audio and display strengths. The F9 Ultra is not for everyone. Its size and weight will not suit all users, and the ultrawide remains a weak point. But for buyers who prioritize sound, screen, and battery life, Poco's latest flagship makes a clear case that the brand is growing into its strengths.
