研調機構Counterpoint Research公布今年第三季全球智慧型手機銷售排行榜，前十名機型中蘋果iPhone四款進榜，包辦前三名，惟iPhone 16系列因銷售時間過短，無法擠進前十大，且跟去年的排行榜相比，以三星為首的安卓陣營影響力有所提升。三星Galaxy A15 4G甚至衝上第四名，為銷量最好的安卓手機，顯示4G市場仍有一定規模。
前三名分別是iPhone 15、iPhone 15 Pro Max和iPhone 15 Pro，接著iPhone 14名列第八名，三星Galaxy A15 4G衝上第四名，第五至第七名也都三星A系列，A15 5G、A35 5G與A05，三星Galaxy A15 4G為全球銷售最佳的安卓手機，5G版本緊追在後。
除了蘋果與三星之外，紅米12C與13C連續兩年擠進前十大榜單，顯示4G手機在新興市場的需求量仍高，甚至提升安卓手機的市佔率。去年同期，第四名為iPhone 13手機，今年就換成Galaxy A15 4G，銷售冠軍的佔比也從3.8%降至3.5%。
