Credit: Paul Jones / Android AuthorityTL;DRApple may finally be embracing bigger batteries, with the iPhone 18 Pro Max reportedly getting a 5,567mAh cell in the US.US models pack larger batteries than Chinese variants thanks to Apple’s eSIM-only design, which frees up internal space by removing the physical SIM tray.Battery size is now a major selling point for flagship Android phones. Samsung, OnePlus, and Xiaomi have been gradually increasing the battery capacities of their devices over the last few generations, with many now shipping with batteries well above 5,000mAh. Apple, however, has taken a different approach, generally squeezing longer battery life out of efficient silicon and tight hardware-software integration rather than chasing bigger numbers. That may be shifting soon.The iPhone 18 Pro appears in China’s 3C regulatory database with a 4,056mAh battery for the Chinese version and a 4,288mAh battery for the US model. That’s a slight bump from the iPhone 17 Pro, which featured 3,988mAh and 4,252mAh batteries, respectively, as noted by Digital Chat Station on Weibo (via MacRumors).
