Apple has been doing nothing to improve the battery capacity of the iPhone. The latest iPhone 12 mini is only 2227 mAh. For a flagship machine, such a low battery capacity is simply unimaginable, which is one of the main reasons for the poor endurance of the 12 mini. This situation may improve in the future, because Apple's latest patent exposure shows that improving the battery capacity of the iPhone is no longer an imaginary thing.
One of Apple's latest patents is likely to increase battery density. Under the action of new materials, the battery will output energy at a more stable voltage and minimize the energy loss rate, so that the battery can be maintained at a higher health level for a longer period of time. To sum up, it is to slow down the aging speed of batteries. This patent can improve the battery capacity and use energy more effectively. Apple has made it clear that this patent can be used on the iPhone.

Apple's other two new patents
One patent is to use the internal space of the equipment fuselage more effectively, and use a larger capacity battery without affecting other components. This patent can make the battery have a more stable voltage when it is more closely attached to other components, thus ensuring the battery to be efficient and stable when discharging.
The other patent seems to be the logistical support of the first two patents. The phenomenon of battery bulging is common on mobile phones in recent years. Once this phenomenon occurs, the security of the equipment will not be guaranteed, which is also a problem that some digital products have to face now. If iPhone wants to improve battery capacity, it must consider this aspect, so this patent will have two functions: detection and intervention.
