OnePlus Open 2 to have a massive battery, rumor claims

OnePlus is working on a new foldable with a massive battery improvement, revealed Digital Chat Station. The Open 2 might reach the 6,000 mAh threshold, revealed the leakster on their Weibo page. The phone is expected in Q1 2025 with a Snapdragon 8 Gen 4 chipset.

The new cell might be a result of the Glacier Battery technology, which OnePlus recently announced in China in partnership with CATL.

It is a silicone-carbon solution that is more efficient, durable, and extremely energy-dense – the Ace 3 Pro is expected to be the first device with the new cell that packs 763 Wh/L, which is 23% better than the current Li-Ion cells.

The OnePlus Open arrived with a 4,805 mAh battery, and it performed well in our battery life test compared with other phones with the same form factor.

With the battery technology evolving, we expect a heated competition between Open 2 and other competitors, especially since the vivo X Fold3 Pro and Honor Magic V3 also have Si/Co batteries with a 5,700 mAh and 5,150 mAh capacity, respectively.
