The OnePlus 15 will apparently have a 7,000mAh or higher battery.
That means the upcoming phone could have a much bigger battery than the Galaxy S25 series.
The phone is also tipped to arrive with a ‘SuperBlack’ color option that could make it look like a “black hole.”

We thought the OnePlus 13 was one of the best Android phones of 2025, but OnePlus is undoubtedly hard at work on the follow-up. We’ve already seen a few apparent OnePlus 15 leaks, and it looks like another major leak has given us more details.

Reliable tipster Digital Chat Station revealed a few apparent OnePlus 15 features on Weibo. The leaker noted in response to a follower that the OnePlus 15’s battery is at least 7,000mAh in size. That makes it almost twice as large as the Galaxy S25 Edge and its 3,900mAh battery, and 2,000mAh larger than the Galaxy S25 Ultra. It’s also a notable boost over the OnePlus 13’s already sizable 6,000mAh battery.
