The OnePlus 15 delivers the most complete flagship experience in the OnePlus lineup, powered by the Snapdragon 8 Elite Gen 5 and a massive 7,300mAh silicon-carbon battery that routinely provides two-plus days of real-world use. It’s the fastest Android phone available — apps launch instantly, gaming runs at sustained high frame rates, and multitasking is effortless with up to 16GB of LPDDR5X RAM. IP68/69/69K durability ratings make it tougher than any Samsung or Apple flagship, surviving submersion to 2 meters and high-pressure water jets. The 6.78-inch 165Hz AMOLED display is superb for gaming with razor-thin 1.15mm bezels. The triple 50MP camera with 3.5x telephoto is capable, but the loss of Hasselblad tuning means it doesn’t quite match the OnePlus 13. At ~$899, it undercuts the Galaxy S26 Ultra by over $400.

Multiple reviewers call the OnePlus 13 the best all-around Android flagship ever made — and many actively prefer it over the newer OnePlus 15. The Hasselblad-tuned triple 50MP camera system featuring Sony’s LYT-808 sensor and a 3x telephoto produces the best photos in OnePlus history, with natural color science and strong low-light performance. The 6.82-inch QHD+ 120Hz LTPO display is sharper than the OP15’s 1.5K panel, and the Midnight Ocean vegan leather finish remains the most distinctive phone design on the market. The Snapdragon 8 Elite still delivers flagship-tier performance, and the 6,000mAh battery comfortably lasts a full day. OxygenOS is clean and responsive with 4 years of OS updates. Now regularly discounted to ~$750, it’s arguably the best value in flagship Android phones.

The OnePlus 15R packs a current-gen Snapdragon 8 Gen 5 chip and a staggering 7,400mAh battery — actually larger than the OP15 — into a $699 package. This is the first time a OnePlus R-series phone gets a brand-new processor instead of a hand-me-down, and the performance leap is significant: benchmarks put it ahead of most 2025 flagships. The 6.83-inch 165Hz AMOLED display is vibrant and responsive, and the IP68/69K build matches the pricier OP15 for durability. Battery life is extraordinary — consistently two-plus days between charges with 80W wired charging. The significant trade-off is the camera: with only a 50MP main and 8MP ultrawide, there’s no telephoto at all, making it less versatile than even the cheaper OnePlus 13R for photography.

The OnePlus 13R delivers a more balanced experience than the 15R for $100 less, and in some ways it’s the smarter buy. The Snapdragon 8 Gen 3 still outperforms most mid-range competitors, handling demanding games and heavy multitasking without stutter. Unlike its successor, the 13R includes a 50MP telephoto alongside the 50MP main and 8MP ultrawide, giving it meaningfully better photographic versatility — portrait shots benefit from the dedicated zoom lens. The 6.78-inch 120Hz LTPO display adapts down to 1Hz for better battery efficiency, and the 6,000mAh battery with 80W charging comfortably lasts a full day. OxygenOS is clean with 4 years of OS updates and 6 years of security patches. The trade-off is IP65 vs IP69K on newer models. At ~$599, it’s the value sweet spot for the lineup.

The OnePlus Open remains the only foldable in the OnePlus lineup, and despite launching in late 2023 it still impresses with its large 7.82-inch inner display and polished multitasking software. Open Canvas lets you run three apps simultaneously with intuitive drag-and-drop — one of the best foldable software experiences available. The Hasselblad-tuned camera with a 48MP main, 64MP 3x periscope telephoto, and 48MP ultrawide delivers solid results, and 16GB of RAM keeps everything smooth. The 6.31-inch cover screen handles quick tasks well. The trade-offs are age: the Snapdragon 8 Gen 2 is two generations behind, the 4,805mAh battery can’t match modern flagships, and the update window is shrinking. OnePlus has discontinued this model in the US with no successor announced. Discontinued — expect limited availability.
