iQOO 15 Full Specifications: Display, Camera, Battery and Performance

The iQOO 15 is not trying to be a “budget flagship” or a toned-down premium phone. This is a full-blown flagship built for raw performance, hardcore gaming, a crazy bright 2K display and a massive battery. It launched first in China and is now headed to markets like India with serious hardware and long-term software support.

If iQOO 15 you’re someone who plays heavy games, watches a lot of content and wants a phone that just doesn’t slow down, the iQOO 15 is aimed directly at you.

Design and Build: Premium and Tough

The iQOO 15 is a big phone – there’s no hiding that. It has a tall body, slim bezels and a large camera island at the back that immediately tells you this is a performance device.

The phone weighs around 215 grams and is roughly 8.1 mm thick. It feels solid and reassuring in the hand, not flimsy.

The iQOO 15 back design follows iQOO’s signature racing-inspired look, with colour options like a “Legend” white version, darker performance-themed variants and even a special game-themed collector’s edition in some markets.

What really makes it stand out is durability:

You get IP68 and IP69 certification, meaning it is resistant to dust, submersion in water and even high-pressure water jets.

This is higher-grade protection than many regular flagships, so it’s well suited for people who don’t want to baby their device.

In short, the iQOO 15 looks and feels like a high-end phone that’s meant to be used hard, not just shown off.

Display: 6.85-inch 2K+ LTPO With 144Hz and Extreme Brightness

The display is easily one of the biggest talking points of the iQOO 15.

Size: 6.85-inch curved AMOLED panel

Resolution: 2K+ (around 1440 × 3168), giving very high pixel density and razor-sharp text

Refresh rate: up to 144Hz with LTPO, which can dynamically drop to lower refresh rates to save power

Panel tech: Samsung M14 LTPO, one of the latest-generation OLED panels

Brightness: peak brightness figures go into the thousands of nits, making it one of the brightest smartphone screens available

HDR: support for HDR standards like HDR10+, plus deep blacks and rich contrast

In real-world use, that translates into:

Excellent outdoor visibility, even under harsh sunlight

Incredibly smooth scrolling and animations at 144Hz

Vibrant and punchy colours for movies, games and social media

Very sharp detail thanks to the 2K-level resolution

Simply put, this is a top-tier flagship display and is one of the main reasons to buy the iQOO 15.

Performance: Snapdragon 8 Elite Gen 5 + Q3 Gaming Chip

Inside the iQOO 15 sits Qualcomm’s Snapdragon 8 Elite Gen 5 chipset, built on a cutting-edge 3nm process. This is one of the fastest Android chips in the world right now.

Key performance highlights:

Super-fast CPU cores with clock speeds crossing 4 GHz on the prime core.

A powerful Adreno GPU designed for high-frame-rate gaming and heavy graphics tasks.

Up to 16 GB of LPDDR5X RAM and as much as 1 TB of UFS 4.1 storage in the top variants.

On top of that, iQOO includes a dedicated Q3 gaming / supercomputing chip that:

Helps stabilise frame rates in games

Handles some display and rendering tasks

Works together with the cooling system to keep temperature under control

In practical terms, you can expect:

Flagship-level performance in everything: games, camera, multitasking and AI features

Very high benchmark scores

Smooth gameplay at high graphics and high FPS for long sessions

If you care mainly about performance, the iQOO 15 is absolutely in the top league.

Cooling: Large Vapour Chamber for Long Gaming Sessions

High performance is pointless if the phone gets hot and throttles. That’s why iQOO has equipped the 15 with a very large vapour chamber cooling system (in the multi-thousand mm² range).

The result:

The phone maintains more stable performance during long gaming sessions.

It heats up more slowly and cools down more efficiently.

You feel less “burning hot” sensation on the frame and back during extended use.

Coupled with the Q3 gaming chip, this makes the iQOO 15 more than just fast; it’s sustained fast.

Software and Updates: Android 16 With Long-Term Support

The iQOO 15 runs Android 16 out of the box with OriginOS 6 (or a similar customized skin depending on region).

Key points:

The UI is feature-rich with a lot of customisation options, gaming tools, themes and animations.

There are dedicated gaming modes that let you tune performance, touch sensitivity, notifications and network behaviour for serious gameplay.

iQOO promises a long update window – several years of OS upgrades plus multi-year security updates, bringing it closer to what brands like Samsung and Google offer now.

If you prefer a very clean, stock Android look, OriginOS might feel busy at first, but for power users and gamers it offers a lot of control.

Cameras: Triple 50MP Setup With Periscope Zoom

The iQOO 15 doesn’t ignore the camera side just because it’s performance-focused. In fact, the camera hardware is genuinely flagship-level.

Rear camera system:

50 MP main camera with optical image stabilisation, using a high-quality sensor tuned for accurate colour and strong detail.

50 MP ultra-wide camera for landscapes, cityscapes and group shots.

50 MP 3x periscope telephoto camera with optical zoom and the ability to push to very high digital zoom levels for “100x” style zoom experiments.

Front camera:

Around iQOO 15 32 MP selfie camera, good for high-resolution selfies and detailed video calls.

Photography expectations:

In daylight, the main camera delivers sharp, detailed photos with good dynamic range.

The periscope telephoto lens gives more natural-looking zoomed shots and much better portraits than simple digital crop.

Ultra-wide is handy for travel and architecture.

Low-light performance is boosted by both large sensors and the powerful ISP inside Snapdragon 8 Elite Gen 5, plus multi-frame night modes.

For video, you can expect high-resolution recording (up to 4K and beyond on the rear), stabilisation support and multiple modes for vloggers and content creators.

Battery and Charging: 7,000mAh + 100W Wired + 40W Wireless

The iQOO 15 battery is another headline feature of the iQOO 15:

Capacity: 7,000mAh, which is huge for a modern flagship.

Uses advanced silicon-anode battery tech, allowing more capacity without making the phone absurdly bulky.

Charging:

Up to 100W wired fast charging, which can charge the phone very quickly from low to high.

Around 40W wireless charging, which is still very fast for a wireless standard.

Real-world experience:

Heavy users (gaming, camera, 5G, social media) can comfortably get a full day and often more.

Moderate users may push close to two days of usage on a single charge, depending on settings and signal strength.

A quick wired top-up gives you hours of extra use in a short time.

Combined with the efficient 3nm chipset and LTPO display, the battery system makes the iQOO 15 a great choice for people who hate power anxiety.

Connectivity and Extras

The iQOO 15 is a true 2025 flagship in terms of connectivity and features:

Full 5G support on multiple bands for global use.

Wi-Fi 7 for high-speed Wi-Fi with low latency.

Latest-generation Bluetooth, with support for modern audio codecs.

In-display fingerprint sensor, iQOO 15 with fast and accurate unlocking (often ultrasonic depending on region).

Stereo speakers tuned for gaming and media, with support for immersive audio formats.

All the usual sensors – GPS, gyro, proximity, ambient light and more.

Overall, nothing feels “missing” from the spec sheet for this class of device.

India Launch and Pricing (Overview)

For iQOO 15 the Indian market:

Launch is scheduled around late November 2025.

Pricing for the higher variants is expected in the upper flagship bracket (around the typical premium range where it competes with top phones from OnePlus, Samsung and others).

Early buyers may get pre-booking benefits like extended warranty and bundled TWS earbuds, depending on offers at launch.

Exact final prices and bundles can differ by RAM/storage configuration, but this is clearly positioned as a premium flagship, not a budget device.

Final Verdict: Who Should Buy the iQOO 15?

You are a heavy gamer who wants top-end performance, stable frame rates and a huge battery.
