To ensure that no iPhone 13 availability problems persist, mass production of the A15 Bionic kicked off in May. Apple expects higher demand from the upcoming models and, as a result, has reportedly asked suppliers to raise production by 20 percent compared to the iPhone 12 series. This will also include TSMC supplying the company with mammoth-sized shipments of its custom silicon. According to the latest rumor, Apple has ordered 100 million of those A15 Bionic chips.

The total number of A15 Bionic shipments for Apple exceeds 100 million, according to CnBeta. While the report states that these shipments are meant for the iPhone 13 series, it is possible Apple keeps an extra stock for upcoming devices intended to use this chipset. One of them is the iPad mini 6, which is expected to get unveiled later this year with a redesign.
