Xiaomi 15T VS Xiaomi Poco F7 Ultra

Both the Xiaomi 15T and the Poco F7 Ultra share the same IP68 waterproof rating, meaning neither has an edge in water and dust resistance — both can handle submersion in fresh water under standard conditions. Neither features a rugged build or a foldable form factor, so they occupy the same conventional smartphone category.

Where they diverge is in their physical footprint and feel in the hand. The 15T is notably slimmer at 7.5 mm versus the F7 Ultra's 8.4 mm, and lighter at 194 g compared to 212 g. That 18 g difference is perceptible during prolonged use — the 15T will feel less fatiguing in one-handed sessions. The F7 Ultra is also slightly shorter and narrower, resulting in a more compact but thicker and heavier profile, with a larger overall volume (100.989 cm³ vs 95.472 cm³).

For design, the Xiaomi 15T holds a clear advantage for users who prioritize a sleek, lightweight device. Its slimmer chassis and lower weight make it the more pocket-friendly and ergonomically comfortable choice, without any sacrifice in water resistance.

On the surface, these two displays share a great deal: both are OLED/AMOLED panels running at 120Hz with a 480Hz touch sampling rate, and both support the full suite of HDR standards — HDR10, HDR10+, and Dolby Vision — alongside an identical 5000000:1 contrast ratio and Always-On Display. For most content consumption and daily use, the viewing experience will feel premium on either device.

The real differentiator lies in resolution and pixel density. The Poco F7 Ultra packs a 1440 x 3200 px resolution into a 6.67″ panel, yielding a sharp 526 ppi. The 15T, despite its larger 6.83″ screen, tops out at 1220 x 2712 px and 435 ppi. That 91 ppi gap is meaningful — at typical viewing distances, the F7 Ultra's display will render text and fine detail with noticeably greater crispness, which matters for reading, intricate UI elements, and high-resolution media.

The Poco F7 Ultra takes a clear edge in display quality. Its significantly higher pixel density makes it the stronger choice for users who prioritize visual sharpness, while the 15T's larger screen offers more real estate but at a lower fidelity. Neither panel has a secondary screen, so that trade-off is the defining factor here.

The chipset gap here is substantial. The Poco F7 Ultra runs on the Snapdragon 8 Elite — a 3 nm flagship SoC — while the 15T is powered by the Dimensity 8400 on a 4 nm node, a decidedly mid-range platform. The benchmark numbers make this gap concrete: the F7 Ultra scores 2,580,490 on AnTuTu versus 1,821,100 for the 15T, and its Geekbench 6 single-core result of 2970 is nearly double the 15T's 1571. Single-core performance is particularly telling for everyday responsiveness — app launches, UI fluidity, and latency-sensitive tasks will all feel snappier on the F7 Ultra.

The memory story also favors the F7 Ultra in meaningful ways. It ships with 16 GB of RAM running at 5300 MHz, versus 12 GB at 4267 MHz on the 15T, and offers greater memory bandwidth at 85.1 GB/s compared to 68.2 GB/s. More RAM at higher speed translates to better multitasking headroom and faster data throughput between the CPU and memory. The F7 Ultra also steps up to OpenCL 3 versus the 15T's OpenCL 2, giving it a broader compute capability for GPU-accelerated workloads. Both devices cap at the same maximum memory amount and share 512 GB of internal storage.

The Poco F7 Ultra is the decisive winner in performance. Across CPU throughput, memory bandwidth, and GPU compute, it operates in a higher tier than the 15T. For users who demand top-tier gaming, heavy multitasking, or future-proofing, the F7 Ultra is the clear choice — the 15T's Dimensity 8400 is capable, but it cannot match the Snapdragon 8 Elite across any of the key performance metrics provided.

Both phones field a triple-lens system with the same primary and front camera resolution, OIS, and an identical manual controls suite — so the baseline shooting experience is comparable. The meaningful differences emerge in the details. The F7 Ultra's telephoto lens steps up to 32 MP versus the 15T's 12 MP, and its optical zoom reaches 2.5x compared to 2x on the 15T. Combined with a slightly wider maximum focal length of 60 mm versus 46 mm, the F7 Ultra has a stronger zoom range and more resolving power when shooting at distance. Its main lens also opens to f/1.6 against the 15T's f/1.7, a modest but real advantage in low-light capture.

Video is where the gap widens most sharply. The F7 Ultra can record at 4320p (8K) at 24 fps, while the 15T tops out at 2160p (4K) at 60 fps. These represent different priorities: the F7 Ultra offers higher maximum resolution, useful for cropping in post or future-proofing footage, while the 15T's 4K/60fps ceiling delivers smoother motion for action or sports video. Notably, only the 15T supports HDR10 recording, while the F7 Ultra includes a timelapse function and a second flash LED that the 15T lacks.

The Poco F7 Ultra holds the overall camera edge, driven by its higher-resolution telephoto, greater optical zoom, wider aperture, and 8K video capability. The 15T counters with HDR10 video recording and faster 4K frame rates, making it more competitive for smooth video work — but as a complete camera package, the F7 Ultra offers more versatility.

Across the entire feature set provided, these two devices are virtually identical in their software capabilities — privacy controls, multitasking tools, customization options, and accessibility features are matched point for point. The one meaningful distinction is the Android version: the Xiaomi 15T ships with Android 16, while the Poco F7 Ultra launches on Android 15. A newer base Android version typically means access to the latest platform security patches, API improvements, and any behavioral or UI refinements introduced in that release cycle.

Neither device receives direct OS updates, meaning both rely on Xiaomi's own update cadence rather than expedited patches straight from Google. This levels the playing field somewhat — the practical, day-to-day software experience will be shaped more by Xiaomi's skin than by the underlying Android version difference alone.

The Xiaomi 15T holds a narrow edge here solely by virtue of launching on a newer Android version. For users who care about being on the latest platform baseline out of the box, that distinction is real — but given the identical feature parity across every other software spec provided, it is the only differentiator in this group.

Raw capacity slightly favors the Xiaomi 15T at 5500 mAh versus 5300 mAh on the Poco F7 Ultra — a 200 mAh difference that, in practice, translates to a marginal runtime advantage under similar usage conditions. Neither gap is dramatic enough to be a decisive factor on its own, but the 15T's larger cell does give it a theoretical edge in longevity between charges.

Charging speed, however, tells a very different story. The F7 Ultra supports 120W wired fast charging against the 15T's 67W — nearly double the rate. At 120W, the F7 Ultra can realistically go from near-empty to full in well under an hour, making top-ups during short breaks genuinely practical. The 15T's 67W is still respectable and faster than many competitors, but the gap is significant enough to matter for users with demanding schedules. Additionally, the F7 Ultra adds wireless charging, a convenience the 15T entirely lacks, offering a cable-free overnight charging option.

This is a trade-off without a clear overall winner — the 15T edges ahead on raw capacity while the F7 Ultra leads on charging flexibility and speed. For users who prioritize topping up quickly or charging wirelessly, the Poco F7 Ultra is the stronger choice. Those who prefer a slightly larger battery and are less concerned about charging speed may lean toward the Xiaomi 15T.

Wired audio is off the table for both devices — neither includes a 3.5mm headphone jack, so wireless listening is the assumed default. Both feature stereo speakers, putting them on equal footing for built-in audio output. The divergence comes entirely in Bluetooth audio codec support, and it is one-sided.

The Poco F7 Ultra supports the full spectrum of high-quality wireless audio codecs: aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC. The Xiaomi 15T supports none of them. In practical terms, this means the F7 Ultra can transmit significantly more audio data to compatible wireless headphones, preserving detail and dynamic range that standard Bluetooth SBC or AAC compression would otherwise discard. LDAC in particular streams at up to three times the bitrate of standard codecs, and aptX Lossless enables bit-perfect CD-quality audio over Bluetooth — capabilities entirely absent on the 15T.

For casual listeners using the built-in speakers or entry-level wireless earbuds, this distinction may go unnoticed. But for anyone with a quality pair of Bluetooth headphones that supports these codecs, the Poco F7 Ultra is the unambiguous winner in audio — the 15T's complete lack of high-resolution wireless codec support is a meaningful gap that cannot be addressed through software.

Most of the connectivity foundation is shared: both phones support 5G, dual SIM, NFC, USB Type-C, Bluetooth 6, and an identical sensor array including GPS, gyroscope, compass, accelerometer, and infrared sensor. For everyday connectivity tasks, the experience will be functionally the same on either device.

Two specs break the tie meaningfully. The F7 Ultra adds Wi-Fi 7 (802.11be) to its wireless stack, while the 15T tops out at Wi-Fi 6E. Wi-Fi 7 brings higher theoretical throughput, lower latency, and better performance in congested environments — a forward-looking advantage as Wi-Fi 7 routers become more common. This also directly correlates with the peak download speed figures: the F7 Ultra reaches 10,000 Mbits/s versus 5,170 Mbits/s on the 15T — nearly double the ceiling. In real-world use this gap only matters when connected to infrastructure capable of those speeds, but it represents a meaningful future-proofing difference.

The Poco F7 Ultra takes the edge in connectivity, driven entirely by its Wi-Fi 7 support and the substantially higher download speed ceiling that comes with it. For users who want the most capable wireless stack available today, the F7 Ultra is the clear choice — the 15T is no slouch with Wi-Fi 6E, but it is one generation behind in this specific area.

The miscellaneous specs for these two devices are identical across every data point provided: both include a video light, neither features sapphire glass, a curved display, or an e-paper display. There is simply no differentiator to analyze within this group.

This is a complete tie — the Xiaomi 15T and the Poco F7 Ultra are evenly matched on every miscellaneous specification provided, and neither holds any advantage over the other here.
