POCO F9 Ultra Review

POCO has spent years building phones around a familiar formula: aggressive hardware, capable performance, and pricing that makes competing devices look a little uncomfortable. The POCO F9 Ultra stretches that formula into more expensive territory, perhaps somewhat against its will.

This is a large, heavy, thoroughly equipped Android phone built around Qualcomm’s Snapdragon 8 Elite Gen 5 processor, an 8,050mAh battery, a 185Hz AMOLED display, a 200-megapixel main camera, and one of the most unusual speaker arrangements we’ve seen on a smartphone.

There is even a dedicated rear subwoofer tuned with Bose.

That combination makes the F9 Ultra an interesting proposition. It has the hardware muscle to compete with considerably more established premium phones, yet its now higher pricing means POCO no longer gets to win simply by showing up with an impressive spec sheet.

The F9 Ultra has to feel like a flagship, too. For the most part, it actually does.

Design

There is nothing subtle about the POCO F9 Ultra. Its 6.9-inch display, 235-gram weight, and broad 77.94mm body make this a substantial phone. Anyone coming from a smaller handset will notice the difference immediately.

The aluminum frame gives it the structural feel expected from a premium device, paired with Gorilla Glass 7i up front and a glass-fiber reinforced plastic rear panel.

The POCO F9 Ultra pairs exceptional battery life, flagship performance, and unusually good smartphone audio with the kind of hardware package that makes the most sense when POCO keeps the price aggressive.

The wide camera housing stretches across nearly the entire upper section of the phone. That sounds excessive, yet I did find a practical benefit: the phone sits flat on a table instead of rocking back and forth every time you tap the screen. You likely have experienced this problem with a recent device.

POCO puts the usual camera hardware inside that rear section, along with an infrared blaster and the phone’s dedicated subwoofer. A light ring around the subwoofer can indicate notifications, charging progress, media playback, and certain gaming events.

It’s a busy camera area, yet it gives the F9 Ultra some identity in a category filled with large rectangular camera islands.

The phone carries an IP68 rating for protection against dust and water, and the flat side rails are slightly shaped to provide a more secure grip.

All that being said, there is no getting around the size. This is a phone for buyers who consider “large display” a benefit rather than a warning label.

Display

The 6.9-inch HyperRGB AMOLED panel is one of the F9 Ultra’s better features. It runs at 2608 x 1200 resolution and supports refresh rates up to 185Hz. POCO pairs the screen with a dedicated VisionBoost D8 processor that can handle motion interpolation, image upscaling, and SDR-to-HDR processing.

In everyday use, that translates to an exceptionally smooth interface and plenty of headroom for compatible games.

Brightness reaches 850 nits in typical settings while stepping outside kicks the High Brightness Mode (HBM) up to 2,200 nits. This makes for crisp visibility for outdoor navigation and text messages under direct light.

Numbers like these tend to matter less than the practical result which is outdoor visibility being strong and highlights have plenty of intensity. HDR video, for its part, looks convincing.

Color accuracy is very good, though the default white balance leans slightly cool. Anyone particular about display calibration may want to adjust the color profile.

The panel uses hardware DC dimming rather than relying heavily on high-frequency pulse-width modulation (PWM) behavior at lower brightness levels, which could appeal to users sensitive to display flicker.

Software

The F9 Ultra ships with Android 16 and HyperOS 3. HyperOS remains distinctly Xiaomi in appearance and behavior, though the interface feels quick and responsive on this hardware. Animations are fast, menus respond immediately, and there is enough processing power underneath that the software rarely feels constrained.

One of the more visible additions is Hyper Island, which uses the area around the front camera cutout for timers, media controls, recording status, and other background activity.

It works much like similar notification systems found elsewhere, but it fits naturally into the interface.

HyperConnect extends device sharing and communication across Android, Windows, macOS, and iOS hardware. Depending on the devices involved, it can handle clipboard sharing, file transfer, streaming, notifications, and call synchronization.

POCO includes its HyperAI tools, too, covering tasks such as translation, transcription, subtitle translation, and image-based wallpaper creation.

Software support is scheduled for four major Android version upgrades and six years of security updates. That is respectable, though some competing premium phones now promise longer OS support.

Performance

The Snapdragon 8 Elite Gen 5 gives the POCO F9 Ultra plenty of raw speed. After all, it is one of the highest-powered chipsets on the market so we should expect nothing less.

POCO pairs it with 12GB or 16GB of LPDDR5X memory and UFS 4.1 storage, resulting in the sort of responsiveness expected from a high-end Android phone. Both the memory and storage tech are among the most current and capable.

Geekbench 6 testing that I found returned scores around 3,530 in single-core performance and 10,500 in multi-core testing. Sequential storage write speeds landed around 1,140MB/s.

Nerds appreciate those last few sentences but the more useful takeaway is simpler: apps launch quickly, multitasking feels effortless, and demanding games have plenty of processing power available.

Sustained heat is the bigger concern for heavy users or gamers. POCO uses a dual-layer IceLoop vapor chamber cooling system, yet extended synthetic stress testing can push the Snapdragon chip beyond what the chassis can comfortably dissipate.

The frame becomes noticeably warm and performance throttles under prolonged maximum workloads. To be totally clear, that sounds worse than it tends to be during regular use.

Long gaming sessions remain considerably more stable, with POCO’s WildBoost system managing clocks and thermal limits to maintain consistent frame rates. The phone still becomes warm after extended play, but the dramatic throttling I’ve found observed in testing does not appear to represent normal everyday behavior.

Serious mobile gamers may want to keep the thermal behavior in mind. Everyone else is unlikely to push the hardware that hard.

Cameras

POCO equips the F9 Ultra with three rear cameras: a 200-megapixel main sensor, a 50-megapixel 5x periscope telephoto camera, and a 50-megapixel ultrawide. The main camera, to the surprise of no one, is the strongest of the group.

Its Samsung ISOCELL HP5 sensor combines pixels for standard 12.5-megapixel photos, producing images with strong dynamic range, controlled sharpening, and natural-looking color.

The dedicated 200-megapixel mode can pull out considerably more fine detail in favorable lighting, especially in architecture, signage, and textured surfaces. File sizes can climb into the 30MB to 70MB range, so this is best treated as a specialty option rather than the default shooting mode. A 2x crop from the main sensor works well for portraits, too.

Low-light performance is similarly capable. The main camera does a good job retaining shadow information without turning darker areas into a noisy mess.

The 5x periscope camera is another welcome inclusion. It provides optical stabilization and produces sharp photos with pleasant subject separation during the day. It remains useful after sunset, though image quality starts falling off once digital zoom takes over beyond roughly 10x.

At those longer zoom distances, computational processing can make surfaces such as grass, brick, and foliage look unnaturally smooth.

The ultrawide camera is less convincing than its siblings. Its 102-degree field of view is relatively narrow, autofocus is absent, and color temperature differs noticeably from the main and telephoto cameras. Low-light results lose detail more quickly and can struggle with certain artificial lighting. It works, but it feels like the one camera POCO could spend more time refining. Then again, how often are you actually taking ultrawide shots in lower light?

Video recording reaches 8K at 30fps, with 4K60 available from the main and telephoto cameras.

Audio

Phone speakers rarely deserve their own section, and I tend to typically gloss over the detail in most phone reviews. The F9 Ultra earns one.

I’ve never been that big of a fan of music on handsets, especially in settings where others are around. Either pair a Bluetooth speaker or think twice about whether you even need to throw your favorite playlist on. Don’t be that guy.

POCO worked with Bose on a 2.1-channel audio arrangement consisting of two traditional stereo speakers and an independent rear-mounted subwoofer.

The result has considerably more low-end presence than the average smartphone.This is still a phone, so nobody is confusing it with a bookshelf speaker, but music, videos, and games sound fuller than they do through most handset speakers. Voices remain clear at higher volumes and bass-heavy content has some genuine weight behind it.

The system can adjust left and right stereo channels depending on how the phone is being held, and dedicated gaming profiles can make directional effects easier to identify.

Users who spend a lot of time watching video or gaming without headphones may find the audio system one of the strongest reasons to choose the F9 Ultra.

I’m still going to prefer earbuds or a speaker depending on my situation, but I would actually not have feel the way I do if all phones put out this kind of sound.

Battery Life and Charging

The 8,050mAh silicon-carbon battery is another star in the hardware package. For context, many large premium Android phones still sit around the 5,000mAh mark. POCO manages to fit substantially more capacity into a phone that remains 8.74mm thick.

Battery testing and benchmarks I looked into suggest it produces nearly 30 hours of continuous web browsing and more than 13 hours of continuous 3D gaming. A standardized active-use test reached 24 hours and 35 minutes.

Those figures point to a phone that can comfortably handle a heavy day and, for lighter users, push into a second day without much anxiety.

Charging is quick considering the enormous battery. The 100W wired charging system reached roughly 32 percent after 15 minutes, 61 percent after 30 minutes, and a full charge in approximately 54 minutes.

There is 50W wireless charging, too, along with 27W reverse wired and 22.5W reverse wireless charging for powering accessories or another device. It’s fast in all of the ways you can imagine.

European buyers should note that the wall adapter is not included with the standard retail package.

Battery protection options inside HyperOS can limit charging to 80 percent, adapt charging behavior around usage patterns, or switch between standard and faster charging modes.

Value

This is where the POCO F9 Ultra becomes more complicated. The base 12GB/256GB model is listed at $799 in the United States. European pricing varies considerably by configuration and promotion, with higher-end versions moving beyond €1,000.

At promotional pricing, or one sale, the F9 Ultra makes a very strong case for itself.

An 8,050mAh battery, Snapdragon 8 Elite Gen 5 processor, 185Hz AMOLED display, 5x periscope camera, 100W charging, 50W wireless charging, IP68 protection, and Bose-backed 2.1 audio give buyers an unusually dense hardware package.

At full premium, pricing, the calculation changes. Samsung, Motorola, Xiaomi, and other manufacturers offer compelling alternatives with leaner/cleaner software, longer update commitments, lighter designs, or more consistent camera systems.

POCO can compete with those phones on hardware. The harder question is whether buyers are prepared to spend premium money on a brand historically associated with value-focused devices.

The closer the F9 Ultra sells to its promotional pricing, the easier that decision becomes.

Warranty

POCO provides a one-year limited hardware warranty for the phone, with six months of coverage listed for the battery and included accessories.

Some regions receive extra launch-period benefits, including screen replacement programs or extended coverage. These vary by market and purchase period, so buyers should check the terms that apply where the phone is sold.

Verdict

The POCO F9 Ultra feels like a company testing how far it can stretch its identity.

Its biggest strengths are easy to appreciate. Battery life is excellent, charging is fast, the display is smooth and bright, performance is extremely strong, and the Bose-backed speaker system gives the phone an audio advantage few competitors can match.

The main and 5x cameras are capable, too, though the ultrawide trails behind them. Heavy thermal throttling during sustained synthetic workloads and the 235-gram weight remind you that POCO squeezed a lot of hardware into this chassis.

It’s late 2026, though, and pricing matters more than ever.

At around $729 to $799, the F9 Ultra offers enough unusual hardware to make established flagships uncomfortable. Once pricing climbs toward the €1,000 mark, longer software support, better-balanced camera systems, and stronger brand ecosystems become harder to ignore.

For buyers who value enormous battery capacity, gaming performance, media consumption, and fast charging above having the lightest phone or the cleanest software, the POCO F9 Ultra has a clear appeal.

It may be POCO’s least budget-minded phone yet, but it still works best when the price keeps some of that old POCO value intact.
