The iPhone X has a 2,716 mAh battery, which is smaller than the previous iPhone 7 Plus and iPhone 8 Plus. However, the iPhone X uses a more efficient A11 Bionic chip and OLED screen, so the battery life is better than the previous model. According to official data, the iPhone X can use 12 hours of continuous Internet browsing, 13 hours of video playback and 21 hours of voice calls. In addition, the iPhone X also supports wireless charging and fast charging functions, making charging faster and the user experience more convenient.
