The OnePlus 15R is getting a lot of attention even before its official launch, mainly because the company has confirmed something that smartphone users care about the most — a bigger and longer-lasting battery. The device is set to arrive in India on December 17, and OnePlus has already revealed several important details about its performance, display, camera and charging. With the number of teasers coming out, it is clear that the 15R is going to be one of the main highlights in the mid-premium segment.
largest battery ever used in a OnePlus smartphone
One of the biggest confirmations from OnePlus is that the upcoming phone will feature a 7,400mAh battery, which is the largest battery ever used in a OnePlus smartphone. It is even slightly bigger than the OnePlus 15’s 7,300mAh cell. This immediately makes the 15R stand out because most phones in its segment still use batteries between 4,500mAh and 5,500mAh. With the 15R moving to a much larger capacity, users can expect longer screen time, better standby life and more consistent all-day usage.
Silicon Nanostack technology
OnePlus has also shared how they managed to fit such a large battery without making the phone bulky. The company is using Silicon Nanostack technology, where silicon is added to the battery anode. The higher silicon content helps increase energy density, meaning the battery can store more power in the same physical size. OnePlus says this approach helps them build thin devices while still offering long battery life. According to the brand, the battery will maintain at least 80 percent capacity even after four years of daily charging, which means it is designed for long-term use.
Charging is handled by 80W SUPERVOOC fast charging, allowing the phone to power up quickly even with such a big battery. While the Chinese variant of the Ace 6T supports 100W charging, the global 15R sticks to 80W, which is still quite fast and practical for everyday use.
First smartphone to launch with the Qualcomm Snapdragon 8 Gen 5 chipset

Apart from the battery, OnePlus has confirmed that the 15R will also be the first smartphone to launch with the Qualcomm Snapdragon 8 Gen 5 chipset. This makes the device even more interesting because we usually see the newest Qualcomm processors debut in premium flagship phones first. With the Snapdragon 8 Gen 5 inside, the 15R is expected to deliver fast performance, smooth multitasking and efficient power management. The focus seems to be on providing flagship-level speed in a more affordable price category.
The display is another area where OnePlus has made important upgrades. The OnePlus 15R comes with a 165Hz 1.5K AMOLED screen that can peak at 1,800 nits brightness. This means the display will be very sharp, smooth and easy to view outdoors. The screen can also dim down to 2 nits by default, or even 1 nit using Reduce White Point mode, which helps reduce strain during nighttime use. The panel is TÜV Rheinland Intelligent Eye Care 5.0 certified, indicating that it is tuned for comfortable, long-duration viewing.
On the camera side, OnePlus has confirmed that the 15R will support 4K video recording at 120fps, a feature previously limited to its flagship series. While the company has not shared the full camera layout, reports suggest a dual-camera setup with a 50MP Sony IMX906 primary sensor and an 8MP ultrawide lens. There is no telephoto lens this time, which means the focus is mainly on high-quality primary shooting and smooth video performance.
OnePlus’s Plus Mind feature
The design of the phone is also expected to take some inspiration from the OnePlus 15. Rumours indicate a refreshed camera island and a switch from the classic alert slider to a Plus Key. The Plus Key is designed to work with OnePlus’s Plus Mind feature, which allows users to capture on-screen information and convert it into reminders, events or searchable notes. This feature is already available on some recent OnePlus phones and is now becoming standard on more devices.
Another interesting detail is that the OnePlus 15R is widely believed to be a rebranded version of the OnePlus Ace 6Tlaunched in China. While the Chinese model carries an 8,300mAh battery with 100W charging, the global version has changed a few specifications to align with international standards. Still, the 15R retains most of the important upgrades, especially in battery life, display quality and processing power.
The device is expected to be priced somewhere around ₹45,000 in India, although the official pricing will only be confirmed at the launch event. With this expected price bracket, the 15R will compete directly with devices from iQOO, Realme and Samsung in the same performance segment. Since the 15R is bringing a huge battery, flagship-level processor and fast display refresh rate, it could attract users looking for a performance-focused phone without going for ultra-premium models.
The phone will be available through Amazon India, OnePlus’s official website and offline partner stores right after launch. With the holiday season approaching, the timing of the launch also aligns with festive shopping and end-year deals, which may help the device reach more buyers.
Final Thoughts
Overall, the OnePlus 15R seems to be focusing on practical improvements instead of only aesthetic changes. The large battery, long-term durability, fast charging, high-refresh-rate display and new Snapdragon processor make it a strong option for users who want a reliable smartphone for gaming, streaming, multitasking and all-day use. With confirmed features already creating buzz, the official launch on December 17 will give us a complete look at what OnePlus plans to offer in the mid-premium segment this year.
If the final pricing and camera performance match user expectations, the OnePlus 15R could become one of the most popular choices in its segment. For now, the confirmed features suggest that OnePlus is trying to deliver a balanced phone with power, battery life and everyday usability at its core.
