Apple is preparing for a large production run of the standard iPhone 18. This follows the iPhone 17's successful performance as the top-selling smartphone globally. A leaker on Weibo indicated that iPhone 18 production will begin in late November. The reported volume of inventory is described as substantial. The confidence for this large production stems from the iPhone 17's significant demand. Following its pre-orders, Apple instructed suppliers to increase output by at least 30%. The standard iPhone 17 was the best-selling smartphone in Q1 and Q2 of 2026. It achieved 6% of global unit sales in each of those quarters. The iPhone 18 is expected to have a similar design but with upgrades. These potential upgrades include a smaller Dynamic Island, the A20 chip, and the C2 modem. The iPhone 18 is anticipated to be revealed in spring 2027 alongside other models.
