The OnePlus 15 is set to debut in China on October 27, with a global launch likely to follow. Early leaks and manufacturer disclosures paint a picture of a phone that could shake up the Android flagship field in 2025.
Five reasons the OnePlus 15 could steal the spotlight
OnePlus has been teasing features long before full reveal, and the details we've seen so far suggest this is not just iterative. Here are the five headline elements that could make the OnePlus 15 a game changer.
1. A battery built for marathon use
OnePlus is reportedly packing a gigantic 7,300mAh cell into the 15 — far larger than what Samsung, Google, or Apple currently ship in their flagships. For context, the Galaxy S25 Ultra and many rivals top out around 5,000–5,200mAh. That extra capacity should translate to noticeably longer runtimes between charges, especially for heavy users.
Even better: the OnePlus 15 is said to support up to 120W wired charging and up to 50W wireless charging. So despite the large battery, recharging should be fast, keeping downtime minimal.
2. Top-tier performance with the newest Snapdragon
OnePlus confirms the phone will use Qualcomm's Snapdragon 8 Elite Gen 5 chipset. As a fresh flagship SoC, it promises leading CPU and GPU performance across apps and games. That could put the OnePlus 15 at or near the top of Android benchmarks for 2025 — at least until other vendors roll out the same silicon in early 2026.
3. A display tuned for speed
The company has revealed a 165Hz refresh rate for the display, a spec that typically appears on gaming-focused devices. Mainstream flagships usually cap at 120Hz, so 165Hz offers even smoother scrolling and motion handling for games that can take advantage of it. Expect an extra-fluid UI feel, which many power users will appreciate.
4. Cameras that look competitive on paper
OnePlus says the 15 will include a 50MP triple-camera setup with a 3.5x telephoto (~85mm equivalent) and support for 4K at 120fps Dolby Vision capture. While that doesn’t guarantee it will outclass photography leaders, these specs indicate OnePlus is focusing on versatile, high-quality imaging — building on the strong camera gains from prior models.
5. Advanced cooling to hold peak performance
Thermals matter as much as peak performance. OnePlus is calling its new solution the Glacier Cooling System, which combines a larger vapor chamber with a double-layer capillary structure and a Glacier Supercritical Aerogel. In practice, that should improve heat dissipation, help sustain performance during long gaming sessions, and potentially improve overall battery efficiency.
Put together — a huge battery, very fast charging, the latest Snapdragon silicon, a 165Hz display, capable cameras, and a more sophisticated cooling architecture — the OnePlus 15 could outpace many rivals on real-world usage metrics. If OnePlus follows up the China reveal with a timely global launch, this phone might be the surprising Android highlight of 2025.
