Vivo iQOO 15 VS Xiaomi Poco F7 Ultra

Both the Vivo iQOO 15 and the Xiaomi Poco F7 Ultra share the same core protection credentials: an IP68 rating, meaning both are fully waterproof and can withstand submersion in fresh water. Neither adopts a rugged or foldable form factor, so they compete squarely in the same category of premium, conventional-slab smartphones.

Where they diverge is in their physical envelope. The iQOO 15 is the larger device overall — 163.7 × 76.8 mm versus the Poco F7 Ultra's 160.3 × 75 mm — giving it a noticeably bigger footprint that may challenge one-handed use for smaller hands. The Poco F7 Ultra compensates slightly by being 8.4 mm thick compared to the iQOO 15's slimmer 8.1 mm, though a 0.3 mm difference is barely perceptible in daily handling. More meaningfully, the Poco F7 Ultra is 8 grams lighter at 212 g versus 220 g — a gap that becomes noticeable during extended use, such as prolonged gaming sessions or long calls.

On balance, the Poco F7 Ultra holds a modest ergonomic edge: it is lighter and more compact, making it the more pocketable and comfortable option for sustained use. The iQOO 15 counters with a slightly slimmer profile, but that advantage is marginal. Both phones are functionally equivalent on protection, so for users who prioritize comfort in hand and on the go, the Poco F7 Ultra's dimensions give it the nod in this category.

Both phones use OLED/AMOLED panels at 1440p resolution, with Always-On Display and HDR10+ support — a strong shared foundation. The iQOO 15 goes larger at 6.85″ versus the Poco F7 Ultra's 6.67″, which suits media consumption and gaming, but the Poco F7 Ultra's smaller screen actually yields a slightly sharper image at 526 ppi compared to 508 ppi — a difference that is negligible in practice at typical viewing distances.

The sharpest contrast between these two panels lies in brightness and refresh rate. The iQOO 15 pulls ahead significantly with a 2600 nits typical brightness versus 1800 nits on the Poco F7 Ultra — a gap that translates directly to far superior outdoor legibility in sunlight. Conversely, the Poco F7 Ultra counters with Dolby Vision support, a premium HDR format that enables richer, more precisely graded visuals when streaming compatible content from platforms like Netflix or Apple TV+. The iQOO 15 tops out at HDR10+, which is capable but lacks the mastering precision of Dolby Vision. The Poco F7 Ultra also features branded damage-resistant glass, adding a layer of everyday durability the iQOO 15 does not explicitly offer. The iQOO 15's 144Hz refresh rate edges out the Poco F7 Ultra's 120Hz, though the real-world smoothness difference between the two is subtle for most users.

The display category is genuinely split by use case. The iQOO 15 is the stronger choice for outdoor use and fast-paced gaming, thanks to its higher brightness and refresh rate. The Poco F7 Ultra is better suited for cinematic viewing and everyday durability, owing to Dolby Vision support and its protective glass. Users who prioritize brightness and sheer screen real estate should lean toward the iQOO 15; those focused on content fidelity and build resilience will find the Poco F7 Ultra more compelling.

At first glance these two phones look nearly identical on paper — same RAM, same architecture, same GPU model, same memory bandwidth. The critical distinction is generational: the iQOO 15 runs on the Snapdragon 8 Elite Gen 5 while the Poco F7 Ultra uses the original Snapdragon 8 Elite. That one generation gap has measurable consequences across every performance metric provided.

The benchmark numbers tell the story clearly. The iQOO 15 scores 4,030,245 on AnTuTu versus 2,580,490 for the Poco F7 Ultra — a lead of roughly 56%. In Geekbench 6, the iQOO 15 posts 3,234 single-core and 10,059 multi-core against the Poco F7 Ultra's 2,970 and 8,887 respectively. These are not marginal differences; they reflect the iQOO 15's higher peak CPU clocks (4.6 GHz vs 4.32 GHz on the prime cores) and a faster GPU clock of 1200 MHz versus 1100 MHz. In practice, this translates to snappier app launches, smoother sustained gaming under load, and more headroom for demanding AI-driven tasks. Both chips share the same 3 nm process and 8.2W TDP, so the iQOO 15 achieves its performance advantage without a thermal or efficiency penalty. Storage is also worth noting: the iQOO 15 ships with up to 1TB of internal storage versus the Poco F7 Ultra's 512GB maximum.

The iQOO 15 holds a clear and substantial performance edge in this category. For users who push their phones hard — competitive gaming, heavy multitasking, or future-proofing against increasingly demanding apps — the newer chipset generation makes a tangible difference that the benchmarks consistently confirm.

The camera systems on these two phones diverge in meaningful ways despite sharing the same 50 MP primary resolution and 32 MP front camera. The Poco F7 Ultra immediately stands out with its wider main aperture of f/1.6 versus the iQOO 15's f/1.9 — a significant difference that allows considerably more light onto the sensor, directly benefiting low-light photography. The Poco F7 Ultra also includes optical image stabilization (OIS), which the iQOO 15 lacks entirely. OIS is one of the most impactful camera features in real-world use, reducing blur in handheld shots and dramatically improving video smoothness, particularly in low-light or while moving.

The iQOO 15 reclaims ground in a few specific areas. Its telephoto lens delivers 3x optical zoom compared to 2.5x on the Poco F7 Ultra, giving it a longer reach for distant subjects. It also supports RAW capture, which the Poco F7 Ultra does not — a meaningful advantage for photographers who post-process images, as RAW files retain far more detail and dynamic range than compressed JPEGs. On the video side, the iQOO 15 records 8K at 30 fps while the Poco F7 Ultra caps at 24 fps for 8K, giving the iQOO 15 smoother motion at the highest resolution tier. The Poco F7 Ultra counters with a dual-LED flash unit versus the iQOO 15's single LED, which can produce more balanced and natural-looking flash illumination.

This category is genuinely competitive, with each phone holding distinct advantages. The Poco F7 Ultra is the stronger all-around shooter for everyday users — its brighter aperture and OIS combination produces more consistently sharp, well-exposed images across varied conditions. The iQOO 15 appeals more to enthusiast photographers and videographers who value greater zoom reach, RAW flexibility, and higher-frame-rate 8K video. Neither phone dominates outright; the right choice depends heavily on shooting priorities.

Strip away the single version number and these two phones are running effectively identical software feature sets — every privacy control, productivity tool, and system capability listed is shared between them. That makes the Android version the only meaningful differentiator in this category: the iQOO 15 ships with Android 16 while the Poco F7 Ultra launches on Android 15.

One generation ahead at launch is a tangible advantage. Android 16 brings the latest platform-level security patches, privacy refinements, and system optimizations out of the box — meaning the iQOO 15 starts its lifecycle one step ahead in terms of software currency. It also implies the iQOO 15 will reach end-of-support one cycle later, which matters for users who keep their phones for multiple years. Neither device receives direct OS updates from Google, so both rely on their respective manufacturers for future version upgrades — a factor worth keeping in mind when evaluating long-term software support.

The iQOO 15 holds a clear, if narrow, edge in this category purely by virtue of its newer Android version. For users who care about having the latest OS features and the longest possible software runway from day one, it is the stronger choice. For those who consider Android 15 fully current and sufficient, the Poco F7 Ultra is in no way disadvantaged in day-to-day software experience.

The battery category is where the iQOO 15 makes one of its most compelling statements. Its 7000 mAh cell dwarfs the Poco F7 Ultra's 5300 mAh — a 32% capacity advantage that, in practical terms, translates to significantly more screen-on time between charges. For heavy users, gamers, or anyone who frequently ends the day with a nearly dead phone, that extra capacity is a genuine quality-of-life upgrade.

The Poco F7 Ultra responds with faster replenishment speeds: 120W wired charging versus 100W on the iQOO 15, and 50W wireless versus 40W. Higher wattage means a depleted battery reaches full charge more quickly — useful for users who charge in short bursts throughout the day rather than overnight. However, the gap in charging speed is relatively modest, and crucially, the iQOO 15's larger battery means it starts each charge cycle with considerably more energy stored, so even slightly slower charging is offset by the reduced frequency with which charging is needed in the first place. Both phones include a charger in the box and support wireless charging, putting them on equal footing for convenience features.

The iQOO 15 holds the stronger position in this category. A 7000 mAh battery is an outright stamina advantage that the Poco F7 Ultra's faster charging cannot fully neutralize — you can top up quickly, but you still need to top up more often. Users who prioritize all-day or multi-day endurance will find the iQOO 15 clearly superior here; only those who strongly prefer wireless charging speed over raw capacity will find the Poco F7 Ultra's specs more aligned with their habits.

Wired audio is off the table for both phones — neither includes a 3.5 mm headphone jack — so the comparison centers entirely on wireless audio quality and speaker output. On those fronts, the two are largely aligned: both feature stereo speakers and share support for aptX, aptX HD, and aptX Adaptive, covering the full range of Qualcomm's high-quality Bluetooth audio stack. aptX Adaptive in particular is the most capable of the three, dynamically adjusting bitrate up to 24-bit/96kHz for near-lossless wireless audio with compatible headphones.

Where the Poco F7 Ultra pulls ahead is in two additional codecs the iQOO 15 does not support: LDAC and aptX Lossless. LDAC, developed by Sony, is widely supported across premium wireless headphones and earbuds and transmits audio at up to 990 kbps — significantly higher than standard Bluetooth codecs — making it the go-to choice for audiophiles using Sony, Bose, or other LDAC-compatible gear. aptX Lossless goes a step further, enabling bit-perfect CD-quality audio over Bluetooth when the connection conditions allow. Together, these two additions give the Poco F7 Ultra a materially broader and higher-ceiling wireless audio capability.

The Poco F7 Ultra has a clear edge in this category. For casual listeners, the shared aptX Adaptive support on both phones is more than adequate. But for users with premium wireless headphones — especially those in the Sony ecosystem or any LDAC-compatible hardware — the Poco F7 Ultra's additional codec support unlocks a noticeably higher tier of audio fidelity that the iQOO 15 simply cannot match.

Across the broad sweep of connectivity specs, these two phones are remarkably well-matched — both support 5G, Bluetooth 6, Wi-Fi 7, NFC, dual SIM, USB-C, and an infrared sensor, with identical peak download and upload speeds. For the vast majority of users, the day-to-day wireless experience will be indistinguishable between them.

Drilling into the details reveals two small but genuine differentiators. The Poco F7 Ultra's Wi-Fi stack includes Wi-Fi 6E support, which the iQOO 15 omits. Wi-Fi 6E extends into the 6 GHz band, offering lower congestion and higher throughput in environments with many competing devices — a meaningful perk in dense urban apartments or offices where 5 GHz channels are saturated. In return, the iQOO 15 includes a barometer that the Poco F7 Ultra lacks. A barometer enables more accurate altitude readings and can improve GPS positioning accuracy, and is also used by certain fitness and weather applications — a niche but functional sensor advantage.

This category is effectively a wash, with each phone trading one minor advantage. The Poco F7 Ultra's Wi-Fi 6E is likely the more broadly useful of the two additions, benefiting anyone with a compatible router in a congested wireless environment. The iQOO 15's barometer serves a narrower audience. Neither difference is significant enough to be a deciding factor on its own, making connectivity essentially a tie between these two devices.

The miscellaneous specs for the Vivo iQOO 15 and the Xiaomi Poco F7 Ultra are identical across every data point provided: both include a video light, neither uses sapphire glass, and both feature flat, standard OLED panels with no curved or e-paper display. There is nothing in this category to separate them.

This is a complete tie. No advantages or disadvantages exist for either product based solely on the data provided here.
