Nonetheless, if true, the OnePlus 16’s rumored high-capacity battery may spell unhealthy information for the remainder of the flagship smartphone.
OnePlus makes use of a couple of methods to cram high-capacity battery cells into comparatively small smartphones.

This expertise helps OnePlus match giant batteries into small packages whereas managing thermals. OnePlus additionally splits giant total batteries into smaller dual-cell designs on telephones just like the OnePlus 15.
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 strategy 9,000mAh in dimension, it is affordable to count on these cells to take up more room contained in the cellphone. It is potential that OnePlus may need to make related compromises on the OnePlus 16 to hit this goal because it did on the OnePlus 15 this technology.
It’s totally early within the OnePlus 16 rumor cycle, and every part is up within the air. Current leaks have pointed to the OnePlus 16 course-correcting OnePlus’ errors with the OnePlus 15.

The OnePlus 15’s trade-offs had been uninspiring for a couple of causes. Notably, the OnePlus 15’s hallmark help of 165Hz refresh charges is simply obtainable on a couple of apps. If you happen to do not occur to make use of the apps and video games that help the ultra-high refresh charges, the OnePlus 15 provides you worse show high quality with none of the advantages. The cellphone additionally tends to run heat in sure conditions, which is not preferrred for a gaming-focused flagship.
Whereas we have examined the OnePlus 15’s cameras to carry out nicely in lots of instances, it is arduous to justify paying extra for much less, and that is what OnePlus is asking clients to do right here. The OnePlus 15’s digicam {hardware} is a downgrade in comparison with the OnePlus 13, and there isn’t any Hasselblad processing. The OnePlus DetailMax engine is stable, however some OnePlus followers will miss the previous model of picture processing.
With these shortcomings in thoughts, it’s extremely straightforward to make the case that the OnePlus 13 is a extra well-rounded smartphone than the OnePlus 15. It is proof that battery life is not every part. If the OnePlus 16 certainly plans to extend battery capability by a big margin but once more, the corporate should guarantee this does not damage the cellphone’s total versatility.
