It was rumoured that almost all next generation Chinese flagship phones will bring much larger batteries (~/+6000mAh).
Some people speculated that the reason for this, is that the Snapdragon 8 Gen 4 will not be efficient, and hence OEMs are increasing battery sizes to compensate.
Others argued otherwise, saying that the much bigger batteries in the new generation of Chinese flagship phones have nothing to do with the Snapdragon 8 Gen 4. It's simply a progression in battery technology.
It seems the latter group of people may have been right. Chinese OEMs have unveiled new flagship phones with the Dimensity 9400 chip with big batteries (+/~6000 mAh). We know the Dimensity 9400 is a very efficient chip, thanks to Geekerwan's review.
