If what The Investor reports is true, Samsung may return to provide accessories for the iPhone. Although not mentioned more than 7nm chip, we also know a little more about iPhone of next year. Maybe it will be twice as effective as the iPhone 7 when there's an A10 Fusion chip with 16nm.
Smaller chips mean that it takes up less physical space, there's more room for bigger batteries or other components. Smaller chips also mean less power and with the same battery size as on iPhone 7. Apple can increase processing power.
Apple still hates Samsung because of the iPhone's Galaxy replication phone, but it is clear that the two companies need to be together to succeed. Samsung produces what Apple needs to create millions of iPhones every year, and Apple also has its own user base. As long as Samsung keeps the contract to supply components for the iPhone, it will continue to exist.
