iQOO has officially confirmed that its upcoming flagship smartphone, the iQOO 15, will feature a 7000mAh Blue Ocean battery. The company revealed the details ahead of the launch, which is scheduled for October 20 at 7:00 PM in China.
The new Blue Ocean battery uses a single-cell structure instead of the more common dual-cell design. According to iQOO, this layout improves both durability and energy density. The phone supports 100W wired fast charging and 40W wireless charging. It also offers compatibility with PPS and PD charging protocols at up to 55W.


iQOO 15 will debut with a new Global Direct Power Supply 2.0 system that allows the phone to stay cool while charging and gaming simultaneously. This system aims to reduce thermal buildup, especially during extended gaming sessions.
The company also shared performance benchmarks. In a 30-minute high-load map test in an open-world mobile game running at 60 fps and ultra-high graphics settings, the phone maintained a 1% low frame rate of 57.8 fps. iQOO attributes this to the Monster Supercore Engine, which maximizes the output of the Snapdragon 8 Elite Gen 5 processor. The chipset works alongside iQOO’s in-house Q3 e-sports chip and supports full-scenario ray tracing.

Talking about other specs, iQOO 15 features a 6.8-inch flat 2K Samsung Everest OLED display. It includes M14 light-emitting material, supports a 144Hz refresh rate, 6000 nits peak brightness, and offers 3200Hz touch sampling.
The camera setup includes a 50MP main sensor with a 1/1.5-inch size and a 50MP periscope telephoto sensor with a 1/2-inch size, 70mm focal length, and 3X optical zoom.
Additionally, the device features a large 8K VC Ice Dome cooling system, symmetric dual speakers, an ultrasonic fingerprint sensor, and an IP-rated design for water resistance.
