Verdict
The Poco F8 Ultra positions itself as a high-end smartphone and is equipped with a suitably powerful SoC. It also features a bright and colour-accurate 120-Hz AMOLED display, a solid triple-camera setup, USB 3.2 support, IP68 certification, a 6,500 mAh battery and fast charging both wired and wireless. In addition, the device delivers excellent Bose-tuned audio.
That said, the display is not based on power-saving LTPO technology, 6-GHz Wi-Fi is missing, and the smartphone shows significant heat development under sustained stress tests. Software update support could also be more generous.
Despite these shortcomings, the Poco F8 Ultra offers a very strong overall package that faces little direct competition in its price segment.

The second Ultra model followed quickly, with the Poco F8 Ultra replacing its predecessor after just around eight months. Poco has sought to reassure buyers, however, stating that this accelerated release cycle is intended as a one-off strategic adjustment rather than a permanent change to the company's internal release calendar.
Unfortunately, Xiaomi has also increased prices. The Poco F8 Ultra is once again available in two storage configurations, 12 GB/256 GB (MSRP: €830) and 16 GB/512 GB (MSRP: €900), representing price increases of €80 and €100 respectively compared to the previous generation. At the time of writing, no officially confirmed US pricing has been announced.
Specifications – Poco F8 Ultra
Case – Poco F8 Ultra relies on Poco Shield Glass
The Poco F8 Ultra is available in Black and Denim Blue colour variants. On the black model, the frame is matte black and the rear panel is made from a fibreglass composite. The blue version, by contrast, uses a silicone-resin-based nanomaterial designed to mimic the look of denim, paired with a matte silver aluminium frame. The chassis has a nominal thickness of 8.3 mm, which we were able to confirm. Including the camera module, thickness increases to up to 11.9 mm.
Build quality appears high overall. The denim-style rear panel features a coarse texture and offers very good grip, although it feels more rubber-like than fabric-like to the touch. Panel gaps are tight and even, and the smartphone exhibits only minimal creaking when subjected to torsional stress. In addition, the device is certified to the IP68 standard, making it resistant to both dust and water. The front is protected by Poco's in-house Poco Shield Glass.
Features – Poco smartphone with fast USB 3.2
In contrast to the Pro model, the Poco F8 Ultra features a fast USB 3.2 port that supports wired image output. The high transfer rates in the copy test (768.14 MB/s) actually speak in favor of the faster Gen 2 standard.
As expected, the device does not feature an audio jack or microSD support. It supports Xiaomi's offline communication, but does without UWB.
Software – six years of updates
The Poco F8 Ultra ships with Google Android 16 and Xiaomi’s HyperOS 3.0. According to the manufacturer, it is set to receive four years of Android version updates and a further two years of security patches. Given the device’s high-end ambitions, longer software support would have been desirable.
Xiaomi’s HyperAI features are also included. However, the system comes with a considerable number of pre-installed third-party apps as well as advertising. While these apps can be removed easily, we explain how to disable system advertising in a separate article.
Sustainability
There is only general information about sustainability on the company website, but no full report on the smartphone. The outer packaging is largely free of plastic, but is shrink-wrapped.
Repair by the user is not planned.
Communication – dual-band GNSS and 5G Sub6
The Poco F8 Ultra supports all modern mobile communication standards with a broad frequency band support and showed good reception characteristics during the test, even abroad.
The current Wi-Fi 7 is supported in the WLAN, but without the fast 6 GHz band. However, the transmission rates with 5 GHz are at the expected level and stable.

Satellite lock-on was achieved very quickly outdoors. Indoors, acquisition took slightly longer, but remained comparatively fast.
During a cycling tour, the smartphone was compared with the Garmin Venu 2. The two devices performed at a similar level, although the fitness smartwatch proved to be slightly more accurate. Nevertheless, the Poco F8 Ultra delivered a very good overall result.
Telephony and call quality – F8 Ultra with dual eSIM
When held to the ear, the Poco F8 Ultra impresses with very good voice quality in quiet environments, while the noise suppression is only mediocre and can lead to dropouts on busy roads. The integrated speaker ensures a solid call volume without any significant reverberation effects.
Dual SIM support includes two nano-SIM cards or two eSIMs, including mixed combinations; VoLTE, Wi-Fi calls and Vo5G are also available and worked reliably in the test.
Cameras – Poco F8 Ultra with three 50 MP sensors
Although the front camera of the Poco F8 Ultra has a high resolution, it does not use pixel binning and the full number of pixels is only available in the 4:3 aspect ratio, which is reduced to 24 MP in the default 16:9. The images are coherent and pleasing in daylight, but details are lost early on in low light.
The main camera relies on the brand new Light Fusion 950 sensor, which impresses with a balanced image composition and takes good photos, even in dim light. The ultra-wide angle shows no aberrations in the test, but could do with a little more sharpness. The optical zoom also delivers good results and can also be used as a macro lens (minimum distance: 30 cm). Both the main and zoom sensors can use OIS.
The F8 Ultra can film in 8k with 30 FPS or 4k with 60 FPS. With ShootSteady, a particularly smooth image stabilization is on board, which however only works at 2.8k/30FPS. The front camera is limited to 4k (30 FPS).

Accessories and warranty – optional Xiaomi Care coverage
The Poco F8 Ultra's scope of delivery includes a USB cable (Type-A to Type-C), a SIM eject tool and a black silicone protective case.
The smartphone comes with a 12-month manufacturer warranty, which does not affect the statutory seller warranty applicable in the country of purchase. Optionally, Xiaomi's Xiaomi Care insurance package can be added, costing either €59 or €79 for two years, depending on the level of coverage.
Input devices and handling – ultrasonic in-display fingerprint sensor
The capacitive touchscreen of the Poco F8 Ultra responds reliably and precisely to inputs. Glide characteristics with the preinstalled screen protector are good, although direct interaction with the glass itself feels noticeably more premium.
For biometric security, an ultrasonic fingerprint sensor is integrated into the display and proved to be very fast and reliable during testing. In addition or as an alternative, facial recognition via the front-facing camera can be used, which unlocks the device quickly under good lighting conditions.
The linear vibration motor provides crisp haptic feedback, although it could occasionally be a little stronger.
Display – larger and with lower resolution
Compared to its predecessor, the display of the Poco F8 Ultra has grown slightly in size, but at the same time features a lower resolution. Even so, a sharp image is still ensured with a pixel density of 416 PPI. It is also disappointing that the panel is once again not based on LTPO technology, meaning the refresh rate can only be adjusted dynamically by the system between 60 and 120 Hz.
Brightness levels are high, reaching around 3,500 cd/m² in both the APL18 and HDR measurements. When brightness is adjusted manually, a maximum of 617 cd/m² is available, while activating the sunlight mode allows values of up to 821 cd/m².
As with the F8 Pro, Poco lists DC dimming for brightness control in the specifications. Under the oscilloscope, however, this turns out to be high-frequency PWM dimming with a low base frequency. As a result, the display is comparatively easy on the eyes, but not completely flicker-free.

Outdoors, the Poco F8 Ultra leaves a good impression even on warm days and remains easy to read at all times. At most, reflections can be somewhat distracting.
Viewing angle stability of the panel is very good. At very shallow viewing angles, the image only darkens slightly.
Performance – Poco F8 Ultra comes with Snapdragon 8 Elite Gen 5
The Poco F8 Ultra relies on the cutting-edge Snapdragon 8 Elite Gen 5 and delivers first-class system performance.
Depending on the selected configuration, the smartphone has 12 or 16 GB LPDDR5x RAM available and the UFS 4.1 memory is also one of the fastest.

Emissions – overheating under stress
Temperature
Under sustained load, surface temperatures occasionally approach the 50-degree mark, which is still within an acceptable range.
Less convincing is the SoC's cooling performance, however. Only one of the 3DMark stress tests was able to run to completion, while the others were terminated early due to overheating concerns. Even the lightest test (Wild Life) stopped after 12 out of 20 loops. In everyday use, however, we have so far not observed any resulting limitations.
(-) The maximum temperature on the upper side is 49.8 °C / 122 F, compared to the average of 35.2 °C / 95 F, ranging from 21.9 to 247 °C for the class Smartphone.
(-) The bottom heats up to a maximum of 48.9 °C / 120 F, compared to the average of 34 °C / 93 F
(+) In idle usage, the average temperature for the upper side is 28 °C / 82 F, compared to the device average of 32.9 °C / 91 F.

Battery life
Despite its large battery, the Poco F8 Ultra's runtimes are not among the very best, but they are still very good overall. With just under 22 hours in the Wi-Fi test, it should offer more than enough endurance to last two days.

Notebookcheck overall rating
The Poco F8 Ultra offers a high-quality IP68-certified chassis with either a denim-style or fibreglass finish, a Snapdragon 8 Elite Gen 5, USB 3.2, strong cameras, a bright 120-Hz display, Bose speakers with a subwoofer and a 6,500 mAh battery. Under sustained load, however, the device shows significant heat development, and support for 6-GHz Wi-Fi is missing.
