Chinese phone maker OnePlus releases its big battery 2025 phones this November

November has been a quiet month for smartphone launches in China, with most brands catching up on delayed releases from earlier in the year. OnePlus, however, used the slow calendar to roll out two new phones that immediately stood out for one reason: bigger batteries.

The OnePlus 15 and OnePlus Ace 6 (which will launch internationally as the OnePlus 15R) headline this month’s releases with stamina-focused hardware and cleaner, performance-driven designs. The OnePlus 15 has already drawn mixed reactions. The leather back is gone, the circular camera module has been replaced, and the look feels more in line with mainstream flagships. There are also confirmed feature cuts and a reported camera downgrade, though the core specs remain solid: Snapdragon 8 Elite Gen 5, a 165Hz 1.5K display, and a 7,300mAh battery.

The Ace 6 follows the same direction but at a lower price. It swaps the top-end camera system for a flat 6.83-inch OLED panel with adaptive refresh rates up to 165Hz, powered by the Snapdragon 8 Elite chip and an even larger 7,800mAh battery. It’s positioned as the most aggressive device in the Ace line so far.

We can already see what OnePlus is going for with this pair—stamina and performance—but after the bigger batteries, what should you expect?

Key specifications

We already had a solid idea of what the OnePlus 15 would offer since September, and the final device matches most of those early details. It runs on Qualcomm’s Snapdragon 8 Elite Gen 5, which is the main reason many people are curious about its performance jump this year. The display also steps up to 165Hz from the 120Hz we saw on the OnePlus 13. Only a handful of games can hit those speeds, but the extra headroom will appeal to anyone who games a lot on their phone.

Battery life is another major talking point. The 7,300mAh cell is huge for a mainstream flagship and follows the recent trend of oversised batteries in China-only models. There’s always the question of whether the same battery will reach global variants, since brands often scale it down for Europe and the US, but it’s still one of the standout numbers of this release.

The camera setup switches fully to a triple-50MP arrangement: a wide, an ultrawide, and a telephoto with 3.5x optical zoom. OnePlus has already moved on from its Hasselblad branding, and the DetailMax engine takes over the image tuning this year. It’s too early to judge the results, but the hardware is familiar territory for anyone who has used recent OnePlus flagships.

Charging reaches 120W in China, though international models may not match that. Historically, North America gets a lower rating because of regional power limits, so this might be something to keep an eye on. Wireless charging still peaks at 50W through AirVOOC, but you’ll need the dedicated charger.

The Chinese model ships in three colours—Sand Storm, black and purple. Sand Storm is the one OnePlus keeps highlighting, and the brand says its material is tougher than titanium. The rest of the design is cleaner than last year’s look, with a flat frame, flat back and a square camera module replacing the circular layout. There’s also the Plus Key, which replaces the alert slider and ties into OxygenOS 16 features like Mind Space.

Storage options start at 12GB/256GB and go up to 16GB/1TB. 

Pricing and Availability: One Plus 15

The OnePlus 15 first went on sale in China on October 27, 2025, before beginning its global rollout on November 13. 

In its home market, pricing starts at CNY 3,999 (around $562) for the base model. Globally, the flagship is listed at $899 (₦1,309,900) for the 12 GB + 256 GB variant and $999 (₦1,455,600) for 16 GB + 512 GB. 

Availability has started across Europe and select Asian markets, though U.S. sales are slightly delayed while the device clears FCC certification.

Key specifications

The Ace 6 is the other big OnePlus device that landed today, and on paper, it’s the one people will compare straight against the OnePlus 15. It’s cheaper and slightly cut back in a few areas, but the spec sheet still looks aggressive enough to make anyone wonder if this is the better buy. You’re getting the Snapdragon 8 Elite—the same chip used in the OnePlus 13—so performance shouldn’t stress it unless you’re the type who pushes phones to their limits all day.

The real hook is the battery. OnePlus went all out with a 7,800mAh dual-cell setup backed by 120W SuperVOOC. Charging from empty to halfway in around 16 minutes sounds useful if you’re always on the move, and bypass charging should help keep temperatures steady during long gaming sessions. It’s hard not to notice how this already overshadows the OnePlus 15’s 7,300mAh cell.

On the front, the Ace 6 carries a 6.83-inch flat OLED display at 2800×1272 with 165Hz refresh support and plenty of protections: TÜV Rheinland Intelligent Eye Protection, low-flicker PWM, DC-like dimming above 70 nits, and modes for outdoors or late-night reading. You’ll also see AI-based tricks like blink reminders and adaptive colour temperature. It’s a dense screen at 450ppi and should look crisp enough for gaming and everyday use.

Under the hood, the phone pairs that Snapdragon 8 Elite with up to 16GB of LPDDR5X RAM and 1TB of UFS 4.1 storage. OnePlus also leaned into gaming features again, combining CPU, GPU and NPU through the WindChaser Gaming Engine to hold 165fps in supported titles. There’s also a performance chip, a G2 network chip, and a Lingxi touch chip to tighten response and reduce latency.

For cameras, the Ace 6 takes a simpler approach: a 50MP Sony IMX906 main sensor with OIS and EIS, plus an 8MP ultrawide. It records up to 4K 120fps. The 16MP front camera handles the basics at 1080p. It’s not trying to compete with the flagship tier here, and you’ll feel that in low light or when switching lenses, but the main sensor should be dependable for most people.

The build still feels premium: aluminium and glass, an under-display ultrasonic fingerprint sensor, dual speakers with OReality Audio, NFC, and durability ratings up to IP69K. That’s rare at this price and suggests the phone can survive rough use. Connectivity includes 5G dual-SIM, Wi-Fi 7, Bluetooth 5.4 with LHDC 5.0, and all the major fast-charging standards.

Color options are Quick Silver, Racing Black, and Flash White, with pricing in China starting at 2,599 yuan (about $364). A global version, expected to be called the OnePlus 15R, should arrive soon, so readers outside China may want to watch for that if the specs line up with what they need.

The Ace 6 feels like OnePlus trying to build a battery-first performance phone for people who run their devices hard rather than those who want a high-end camera. If that sounds more like your use case, this is the one in the lineup that stands out.

Pricing and Availability: OnePlus 15R

The OnePlus Ace 6, which launched alongside the 15 in China, is expected to debut internationally as the OnePlus 15R. 

In China, pricing starts around CNY 3,099 for the 12 GB + 512 GB version and reaches CNY 3,399 (roughly US $476) for the higher-end 16 GB + 512 GB model. 

The global edition hasn’t been officially priced yet, but early estimates suggest it will sit near US $599 (₦874,000), keeping it comfortably below the flagship tier.
