OnePlus 15 Leak Reveals Massive Battery Upgrade & Sleek Flat Display

OnePlus seems ready to shake things up in the smartphone world with its next flagship release—the OnePlus 15. According to recent leaks, the brand is going big on battery life, display design, and overall performance, signaling a bold step forward from its previous models.

A Power-Packed Battery Like Never Before

One of the most attention-grabbing rumors? A huge 7,000mAh battery. That’s a significant upgrade from the 6,000mAh cell found in the OnePlus 13, and it could push the OnePlus 15 to the top of the battery performance charts. Despite the increase in battery capacity, OnePlus reportedly aims to keep the device slim and lightweight—a feat that would certainly impress both users and critics.

Flat Display with Cutting-Edge Tech

The OnePlus 15 is expected to feature a 6.78-inch LTPO flat display with a 1.5K resolution. This marks a shift away from the curved-edge 2K displays seen in earlier models, aiming for a cleaner and more symmetrical front look. Thanks to LIPO (Low-Temperature Polycrystalline Oxide) packaging technology, the bezels are rumored to be ultra-thin, giving the phone a modern, polished aesthetic.

Next-Level Performance with Snapdragon Power

Under the hood, the OnePlus 15 is believed to be powered by the Snapdragon 8 Elite 2 chipset (model number SM8850), which promises improved performance and energy efficiency. This upgrade is expected to offer smoother multitasking, better gaming performance, and faster processing across the board.

Blazing-Fast Charging, Both Wired and Wireless

To complement the larger battery, the OnePlus 15 is rumored to support 100W wired and wireless charging. That means even with a 7,000mAh capacity, you won’t be stuck waiting around for your phone to juice up. It’s all about speed and convenience.

Refined Build and Premium Materials

Leaks suggest the phone will have a fiberglass rear panel, which not only looks sleek but also keeps the device light. Add to that an IP68/IP69 water and dust resistance rating, and you’ve got a phone that’s built to survive life’s splashes, spills, and unexpected adventures.

Another standout feature might be a 0916 vibration motor, expected to deliver a more precise and refined haptic experience—perfect for gamers and heavy users. Also rumored is a single-point ultrasonic fingerprint scanner for secure and speedy unlocking.

Triple Camera Setup in the Works

Camera enthusiasts can look forward to a triple 50MP camera system. Based on ongoing A/B testing, OnePlus is exploring different sensor configurations, which may include:

• A primary sensor (standard and ultra-large versions being tested)
• An ultra-wide-angle lens
• A periscope telephoto lens with up to 3x optical zoom

If the final configuration lives up to the leaks, the OnePlus 15 could deliver impressive versatility for both casual and serious photographers.

When Is the OnePlus 15 Launching?

According to insiders, the OnePlus 15 will debut in China around October 2025, with a global release expected in January 2026. As always, expect more details to surface as the launch date approaches.

Final Thoughts

The OnePlus 15 is shaping up to be one of the most exciting smartphones of 2025. From its massive battery and fast charging to its flat LTPO display and upgraded chipset, everything points to a premium flagship experience. If OnePlus delivers on these leaks, this could be the phone that redefines what users expect from a flagship Android device.
