OnePlus disclosed to Digital Chat Station that it is developing a new foldable smartphone with a significant battery boost. The leaker posted on Weibo that the Open 2 may surpass the 6,000 mAh mark. The phone, which will include a Snapdragon 8 Gen 4 CPU, is anticipated in Q1 2025.

The Glacier Battery technology, which OnePlus recently unveiled in China in collaboration with CATL, may have contributed to the development of the new cell.

With a 4,805 mAh battery when it came, the OnePlus Open outperformed other phones of the same physical type in our battery life test.

We anticipate fierce rivalry between Open 2 and its rivals as battery technology advances, particularly given that the Honor Magic V3 and the Vivo X Fold3 Pro also include Si/Co batteries with capacities of 5,150 mAh and 5,700 mAh, respectively.
