A15 Bionic Mass Production for the New iPhone 13 Series Reportedly Taking Place in Late May Apr 6, 2021 11:45 EDT With Apple rumored to unveil the new iPhone 13 series in late September, it obviously means that the company will be working with its supply chain round the clock to ensure that components delivery does not see a surprising delay. One of those suppliers is TSMC, with a fresh report stating that the Taiwanese manufacturer could start mass production of the A15 Bionic chipset in late May. This means the operation could start ahead of schedule, and Apple will have little chance of delaying its upcoming iPhone family.
