However even when utilizing silicon-carbon battery chemistry and Glacier Battery designs, there are limits to how small a smartphone battery can get at excessive capacities. If the OnePlus 16’s battery capability will actually method 9,000mAh in dimension, it is affordable to anticipate these cells to take up more room contained in the cellphone. It is doable that OnePlus may need to make comparable compromises on the OnePlus 16 to hit this goal because it did on the OnePlus 15 this technology.
