OnePlus might be gearing up for a game-changing move in the battery department with its next flagship device, potentially the OnePlus 14 or 15. While the exact name is yet to be confirmed, a new leak suggests that OnePlus is planning something big for its upcoming phone. Rumors from China point to a whopping 7,000mAh battery, making it a significant leap from the already impressive 6,000mAh battery in the OnePlus 13.

If true, this would offer an even longer-lasting battery life, outpacing even the Samsung Galaxy S25 Ultra, which has a 5,000mAh battery, and potentially making this the longest-lasting flagship of 2025.

While larger batteries have traditionally been seen as an overkill, this has become a norm in Chinese smartphones, with brands like Honor already releasing mid-range devices with batteries close to 8,000mAh. OnePlus’s move to push the envelope with a 7,000mAh battery suggests they are looking to capture the attention of power users who care about battery life.

In addition to the monster battery, the OnePlus 14 or 15 might come in a striking new “SuperBlack” color, which is said to be so dark it absorbs nearly all visible light, making it look like a black hole. The phone is also rumored to feature customizable side buttons, potentially adding new functionalities such as a camera shutter button, building on the company’s move to replace the iconic alert slider with a remappable key.

This jump in battery size could signal OnePlus’s growing confidence in its battery technology, particularly its use of silicon-carbon tech that allows for higher energy density without making the phone bulky. If OnePlus can deliver a 7,000mAh battery while maintaining a sleek design, the competition, including Apple and Samsung, may be forced to follow suit.

For those tired of constantly charging their phones, the next OnePlus flagship may be the phone to watch. If these rumors hold up, OnePlus could be the frontrunner for the best battery life in the flagship category.

Too bad OnePlus has never been great with cameras, though. They gotta fix that if they want to compete with Samsung and Apple
