The iPhone 17 emerged as the world's best-selling smartphone in the first quarter of 2026, securing 6% of global unit sales. Following closely were the iPhone 17 Pro Max and iPhone 17 Pro. According to Counterpoint Research, the top 10 smartphone models accounted for 25% of total sales, marking a record for a March quarter. The iPhone 17's success is attributed to significant upgrades, including enhanced storage, improved camera capabilities, and a faster display refresh rate, leading to double-digit growth in major markets like the United States and China, with sales tripling in South Korea. Meanwhile, the smartphone market is experiencing a shift due to a global memory shortage, which is increasing component costs and pressuring margins in lower-priced segments. This has prompted many Android manufacturers to focus more on premium devices, with Apple capturing 21% of all smartphone shipments in Q1. Samsung's Galaxy A series was the most represented in the top 10, with the Galaxy A07 4G being the best-selling Android phone. Looking forward, the trend suggests that the top models will continue to dominate global sales, as demand shifts towards premium devices and long-term value.
