DigiTimes reports that Apple will use smaller internal components for future iPhones, iPads and MacBooks in order to increase the battery size.Image credit: iFixitAccording to industry sources, Apple is expected increase IPD (integrated passive device) adoption for its new iPhones and other iOS devices. This will provide strong business opportunities for TSMC, Amkor and their manufacturing partners TSMC. Sources said that the peripheral chips for iPhones, iPad, and MacBook series are becoming slimmer with greater performance in order to make it easier to store larger-capacity batteries. This will increase the demand for IPDs.Apple intends to increase "significantly" the use of integrated passive devices (IPDs) for peripheral chips in its products. These news chips will be smaller in size, allow for greater performance and take up less space within a device. This will enable for larger batteries.Although the report does not specify when these smaller chips will be available, it does mention that Apple has approved TSMC’s 6th-generation process for mass-producing IPDs to make new iPhones and iPads.The leak of battery capacities for the iPhone 13 lineup earlier this year indicated that the new iPhones would have larger batteries. MacRumors has also seen schematics that reveal the new iPhones will have thicker bodies, which allows for larger batteries.The 2021 iPhones are not mentioned in the report today, but it is reasonable to assume that Apple's new IPD chips and an increase in thickness will allow them to increase the battery size due to the free internal space. Due to the new high-end iPhones' advanced displays, larger batteries could be used.
