The iPhone is a line of smartphones developed and marketed by Apple that run iOS, the company's own mobile operating system. The first-generation iPhone was announced by then–Apple CEO Steve Jobs on January 9, 2007, at Macworld 2007, and launched later that year. Since then, Apple has annually released new iPhone models and iOS versions; the most recent models being the iPhone 16 and 16 Plus, and the higher-end iPhone 16 Pro and 16 Pro Max. As of January 1, 2024, more than 2.3 billion iPhones have been sold, making Apple the largest vendor of mobile phones in 2023.

section{bf Data}

Your iPhone uses data primarily because of background app activity, where apps constantly refresh content, sync data, or check for updates even when you aren't actively using them, along with features like automatic updates, location services, and streaming content which can quickly consume data if not managed properly; additionally, poor Wi-Fi connection can trigger "Wi-Fi Assist" causing your phone to switch to cellular data to maintain connectivity.


section{bf Production}

Up to the iPhone 4, all iPhones and other devices, such as iPod Touch models and iPads, were manufactured by Foxconn, based in Taiwan. In 2011, new CEO Tim Cook changed Apple's manufacturing strategy to diversify its supply base. The iPhone 4s in 2012 was the first model to be manufactured simultaneously by two stand-alone companies: Foxconn and Pegatron, the latter also based in Taiwan. Although Foxconn still produces more iPhones, Pegatron's orders have been slowly increased: the company made part of the iPhone 5c line in 2013, and 30% of iPhone 6 devices in 2014. The 6 Plus model was produced solely by Foxconn.[62] In 2019, Apple investigated reports that some Foxconn managers had used rejected parts to build iPhones.[63] In India, Apple pays Wistron, a Taiwan-based manufacturer with a plant near Bangalore, to assemble iPhones to sell in the region.[64] In 2022, Apple announced that a portion of the iPhone 14 would be manufactured in Tamil Nadu, India, as a response to China's "zero-COVID" policy that has negatively affected global supply chains for many industries.[65] Apple has stated that they plan to shift 25% of iPhone production to India by 2025.[66]
