But while the global market has already begun enjoying this new flagship, the United States is facing an unexpected delay. Due to the recent US federal government shutdown, the FCC approval process has paused, postponing the phone’s US launch. Despite this hiccup, the device’s impressive specifications and innovative features are making waves worldwide.
In this in-depth review, we’ll explore everything the OnePlus 15 brings to the table—from its record-setting 7,300 mAh battery, 165 Hz display, and Snapdragon 8 Elite Gen 5 chipset to its quietly powerful universal remote functionality and on-device Gemini AI integration. Let’s dive deep into what might be one of 2025’s most balanced powerhouse smartphones.
A New Generation Powered by Snapdragon 8 Elite Gen 5
With every new smartphone generation, the processor becomes the single most important factor defining performance, efficiency, AI capabilities, and overall fluidity. The OnePlus 15 is the first US-bound smartphone equipped with Qualcomm’s Snapdragon 8 Elite Gen 5 chipset, offering substantial upgrades in both raw performance and sustained workloads.
Lightning-Fast Performance
Whether you are editing high-resolution 4K videos, juggling multiple resource-heavy apps, or engaging in demanding real-time gaming sessions, the OnePlus 15 glides effortlessly. Thanks to the next-gen CPU and GPU architecture, animations feel sharper, app switching is almost instantaneous, and even extended workloads avoid thermal throttling.
Smarter & Faster On-Device AI
This new chipset significantly boosts AI workloads, a key priority for modern smartphones. Because of the integrated Google Gemini AI, the OnePlus 15 can perform tasks like summarizing text, analyzing content, recognizing objects in images, managing device functions, and organizing your daily activities—all without relying heavily on cloud connectivity.
This not only enhances security (because your data stays on your device) but also makes AI-driven tasks faster, more private, and more reliable.
A Display Built for Elite Mobile Gaming
Gamers will instantly recognize the OnePlus 15’s most visually striking feature—its 6.78-inch, 165 Hz ultra-fluid AMOLED display. It’s a dream come true for serious mobile gamers who crave smooth, ultra-responsive gameplay.
165 Hz: A Refresh Rate Few Phones Can Match
Most premium phones today offer 120 Hz displays, and while the difference between 120 Hz and 165 Hz isn’t always obvious to the human eye, the improvement becomes noticeable in fast-paced games like:
- Call of Duty: Mobile
- Clash of Clans
- Real Racing 3
- Brawl Stars
Several of these titles natively support 165 Hz, letting you experience ultra-responsive gameplay with reduced latency and enhanced motion clarity.
Advanced Cooling with Vapor Chamber Technology
To support extended gaming sessions, OnePlus has incorporated a vapor chamber cooling system, similar to what we see on flagship iPhones and previous gaming-centric Android devices. This ensures:
- Reduced overheating
- More consistent performance
- Better battery efficiency under load
Gamers who play for long hours will appreciate the difference instantly.
Unmatched Battery Life: 7,300 mAh of Pure Power
OnePlus has always been known for fast charging, but with the OnePlus 15, they’ve stepped up the game in battery capacity.
Two-Day Battery Life Confirmed
With a 7,300 mAh battery, the OnePlus 15 surpasses every mainstream flagship from Apple, Samsung, and Google. Even heavy users should expect:
- Up to 48 hours of mixed usage
- One full day of gaming or content creation
- Minimal battery drain during standby
This gives the phone a unique competitive edge, especially for travelers, gamers, and people frequently away from chargers.
Super-Fast Charging Speeds
The charging capabilities are equally impressive:
- 80W wired charging
- 50W wireless charging
These speeds ensure that even this massive battery can be topped up quickly. However, note that full charging speeds are only achievable using OnePlus-branded chargers—a minor limitation for those who prefer universal accessories.
Design Changes: Aesthetics, Build & the Missing Alert Slider
Design loyalty among OnePlus fans is strong, and while the OnePlus 15 features an elegant and polished look, some changes may be divisive.
Refined Design with Micro-Arc Oxidation Finish
The phone features:
- Slim bezels
- A premium matte finish using micro-arc oxidation
- Improved grip and fingerprint resistance
It feels modern, sleek, and comfortable even during prolonged use.
Goodbye, Classic Alert Slider
One of OnePlus’s most recognizable features—the three-way alert slider—has been removed. Replaced by a remappable action button similar to Apple’s “Action Button,” it still offers functionality but lacks the physical multi-position toggle that fans loved.
This change may upset longtime users, but the new button is programmable, which adds a layer of versatility.
Camera System: Big Sensors, Big Megapixels & New Image Engine
OnePlus ended its partnership with Hasselblad for the OnePlus 15, but that doesn’t mean the camera performance has stagnated.
Camera Setup
- 50 MP Main Camera
- 50 MP Ultra-Wide Camera
- 50 MP Telephoto Camera
- 32 MP Front Camera
The new DetailMax Engine is designed to enhance color accuracy, sharpness, and dynamic range.
Performance in Real-World Use
- Daylight photos look detailed, vibrant, and crisp.
- Portrait mode is improved with better edge detection.
- Low-light performance remains good but not flagship-leading.
- Google’s Pixel 10 Pro still dominates in night photography.
For most users, the camera system is more than capable, but professionals may notice its weaknesses in low-light consistency.
The Hidden Gem: Built-In IR Blaster for Universal Remote Control
In an era where most brands have removed the IR blaster, OnePlus continues to offer one of the most useful but underrated smartphone features.
You can instantly control:
- Televisions
- AC units
- Audio systems
- Set-top boxes
- Projectors
With just a quick setup, the OnePlus 15 becomes a universal remote. Whether you’re in a doctor’s waiting room with a blaring TV or want to switch channels discreetly at a sports bar, this feature is surprisingly handy.
It’s a small touch that adds significant real-world value.
AI Features: Gemini Integration & the “Plus Mind” App
OnePlus, like every smartphone manufacturer in 2025, is deeply invested in AI. The OnePlus 15 integrates Google’s Gemini AI directly into its system.
Plus Mind: Your AI-Powered Personal Scrapbook
The built-in Plus Mind app functions as a digital memory hub where you can save:
- Notes
- Voice memos
- Images
- Ideas
- Daily logs
Gemini can then analyze your stored content to:
- Create summaries
- Generate reminders
- Enhance productivity
- Offer personalized insights
Other AI Capabilities
- Voice transcription
- AI photo enhancements
- Smart image sorting
- Task scheduling
- Context-aware suggestions
This device quietly transforms into a personalized AI assistant.
US Launch Delay: The FCC Backlog Problem
While the OnePlus 15 is available in countries like Canada and across Asia, the US launch has been delayed due to the long federal government shutdown, which created a backlog for the FCC.
Why It Matters
Without FCC approval:
- No official US sale
- No carrier distribution
- No local marketing campaigns
OnePlus hopes approvals will come soon, but no timeline is guaranteed.
Pricing & Variants
Despite global inflation trends, OnePlus is maintaining a competitive price point.
Variants
| Variant | Price (Approx.) |
|---|---|
| 256 GB Storage + 12 GB RAM | ~$900 |
| 512 GB Storage + 16 GB RAM | ~$1,000 |
Prices may change based on market conditions, but these numbers align with flagship competitors while offering far more battery life and gaming features.
Conclusion: Should You Buy the OnePlus 15?
The OnePlus 15 stands out in an increasingly crowded flagship market by focusing on practical power rather than gimmicks. Its giant battery, hyper-smooth display, strong AI features, and universal remote add real-world value.
Ideal For:
- Gamers
- Power users
- Travelers
- Tech enthusiasts
- People who want long battery life
While it may not beat the Pixel or iPhone in software sophistication or low-light photography, it offers a uniquely balanced experience very few phones can match.
Once FCC approval clears, the OnePlus 15 has real potential to become a standout choice in the US—especially for users who prioritize performance and battery longevity.
