1. A Bigger, Brighter, And Smarter Display
The display is one of the most noticeable upgrades when comparing the iQOO 15 vs iQOO 13. The iQOO 13 featured a 6.82-inch curved Q10 LTPO AMOLED screen that was already quite impressive with smooth visuals and great colors. However, the iQOO 15 takes it further with a slightly larger 6.85-inch curved Samsung M14 LTPO AMOLED display.
While the size increase might sound minor, it actually makes a visible difference, especially when gaming or watching high-quality videos. The bezels are slimmer, giving you more screen space without making the phone feel bulky.
Both phones share the same 144 Hz refresh rate, ensuring super-smooth motion whether you’re scrolling, gaming, or streaming. The real game-changer, though, is brightness. The iQOO 15 can reportedly reach up to 6,000 nits of peak brightness, which is a big leap from the iQOO 13’s 4,500 nits.
What does that mean for you? Simply put, you will be able to see your screen clearly even under direct sunlight. Outdoor visibility will be drastically better, and HDR videos or photos will look much more vibrant.
Key Takeaway: The iQOO 15 offers a brighter and more vibrant display with a premium viewing experience- perfect for entertainment and gaming.
2. Massive Performance Upgrade
Let us now talk about the performance of the iQOO 15 vs iQOO 13. Performance has always been iQOO’s strongest area, and with the iQOO 15, the brand is pushing boundaries again. The smartphone is powered by Qualcomm’s Snapdragon 8 Elite Gen 5 chipset, which is built on a 3 nm process. That makes it faster and more power-efficient than the Snapdragon 8 Elite chip found in the iQOO 13.
This new processor delivers higher clock speeds and better AI capabilities, meaning smoother multitasking and faster response times. Paired with the Adreno 840 GPU, gaming performance is going to be even more impressive. Expect higher frame rates, improved graphics quality, and reduced lag in demanding games like Genshin Impact or Call of Duty Mobile.
To make gaming even smoother, iQOO 15 will come with a dedicated Q3 gaming chip. This chip helps distribute workload, maintain consistent frame rates, and control temperature, ensuring that the phone stays cool during long gaming sessions.
While the iQOO 13’s Snapdragon 8 Elite was already powerful, the Gen 5 version brings noticeable efficiency gains. The combination of the new architecture, faster GPU, and enhanced AI means not just raw speed but smarter performance overall.
Key Takeaway: Expect a big jump in speed, efficiency, and gaming power. The iQOO 15 is built for gamers and heavy users who demand top-tier performance.

3. Bigger Battery And Faster Charging
Another major upgrade in the iQOO 15 vs iQOO 13 comparison is the battery. The iQOO 13 had a 6,150 mAh unit, which offered decent endurance. But the iQOO 15 is expected to come with a massive 7,000 mAh battery- a significant improvement that will easily power you through a full day and more.
With such a large battery, you can enjoy long gaming sessions, binge-watch videos, or use GPS without constantly worrying about the charge percentage.
iQOO also understands that users need quick charging options, and the iQOO 15 won’t disappoint. It may support 100 W wired fast charging, allowing the battery to fill up from 0 to 100 percent in roughly 30 minutes. On top of that, 40 W wireless charging support could make it even more convenient to top up the phone without plugging in cables.
The iQOO 15’s efficiency will also benefit from the 3 nm Snapdragon chip and the M14 display panel, both designed to use less energy. That means even with a larger and brighter screen, battery life should still improve compared to the previous model.
Key Takeaway: The iQOO 15 offers longer battery life and super-fast charging, making it ideal for gamers, travelers, and busy professionals.
4. Smarter And Smoother Software Experience
A powerful phone deserves equally good software, and this is another area where iQOO 15 brings improvement. It will debut with Origin OS 6, built on Android 16, replacing the Funtouch OS found on the iQOO 13.
This change isn’t just about aesthetics- it’s a complete redesign of how the system feels and functions. Origin OS 6 is expected to have smoother animations, cleaner icons, and improved transition effects. Everything from opening apps to switching between tasks will feel quicker and more refined.
One of the standout additions is AI-powered optimization. The system will learn your habits over time- like which apps you use most or when you typically charge your phone- and make adjustments in the background to save battery or free up memory.
It’s also expected to include smarter privacy settings and better control over notifications, helping you stay focused and secure. Customization is another focus; you can personalize themes, icons, and widgets more easily than before.
While Funtouch OS on the iQOO 13 worked fine, it sometimes felt a bit heavy and inconsistent. Origin OS 6 aims to fix that by offering a cleaner, lighter, and more user-friendly experience, thu making iQOO 15 a better option in the iQOO 15 vs iQOO 13 comparison.
Key Takeaway: With Origin OS 6, the iQOO 15 will feel more polished and responsive, offering a smarter and smoother user experience than the iQOO 13.

5. Better Cameras With Real Optical Zoom
While iQOO1 15 vs iQOO 13 phones are mainly known for speed and gaming, the iQOO 15 is also upgrading its camera system in meaningful ways.
Like the iQOO 13, it will feature a triple 50 MP rear camera setup, but this time with improved sensors and better zoom capabilities.
The main sensor is expected to be the Sony IMX921 50 MP, complete with Optical Image Stabilization (OIS) for steadier shots. This will help capture sharper photos, especially in low-light situations or when your hands aren’t perfectly steady. Colors will look more natural, and dynamic range should improve as well.
The ultra-wide camera also stays at 50 MP but is said to handle details better and reduce distortion at the edges. This makes it great for landscapes or architecture photography.
The biggest improvement, however, is in the telephoto lens. The iQOO 15 will likely include a 50 MP Sony IMX882 periscope camera with 3× optical zoom. This feature will allow you to zoom into distant subjects without losing image quality- a significant step forward from the iQOO 13, which lacked a true periscope zoom lens.
Whether you’re taking close-up portraits, wildlife shots, or capturing far-away subjects, this zoom lens adds a lot of flexibility. You can also expect more stable video recording thanks to improved image stabilization and the ability to record in 8K and 4K resolutions.
Key Takeaway: The iQOO 15 brings meaningful improvements to photography, especially with its new zoom lens- offering clearer, more detailed images in every situation.
Is the iQOO 15 Worth the Upgrade?
After looking at all these improvements, it’s clear that the iQOO 15 isn’t just a small refresh- it’s a genuine upgrade in multiple areas. It combines power, endurance, and intelligence in a single sleek package.
Here’s a quick iQOO 15 vs iQOO 13 comparison:
| Feature | iQOO 15 | iQOO 13 |
| Display | 6.85-inch AMOLED, 6,000 nits | 6.82-inch AMOLED, 4,500 nits |
| Processor | Snapdragon 8 Elite Gen 5 | Snapdragon 8 Elite |
| Battery | 7,000 mAh | 6,150 mAh |
| Charging | 100 W wired + 40 W wireless | 100 W wired |
| Software | Android 16 + Origin OS 6 | Android 15 + Funtouch OS |
| Cameras | Triple 50 MP with 3× optical zoom | Triple 50 MP |
The iQOO 15 feels more refined in every sense- brighter visuals, faster performance, longer endurance, smoother interface, and more versatile cameras.
For gamers, it means better frame rates and cooler performance. For casual users, it means a more fluid and reliable phone that lasts longer. And for photography lovers, the improved zoom lens opens up new creative possibilities.
So, if you have been using the iQOO 13 and are looking for a solid upgrade, the iQOO 15 seems well worth waiting for. It’s shaping up to be one of the most complete flagship phones of 2025- balancing speed, design, and innovation in true iQOO style.
