Alleged battery components for Apple’s next-generation flagship have appeared online, offering the most concrete capacity figures yet for the iPhone 18 Pro Max lineup. A new image circulating on the Chinese social platform Weibo appears to show batteries for two variants of the device, pointing to a modest but meaningful increase over the current generation.
European and U.S. variants show differing gains
According to the leaked image, the European-market version of the iPhone 18 Pro Max — which accommodates a physical nano-SIM alongside an eSIM — will carry a rated capacity of 5,235 mAh. That represents a gain of 412 mAh, or 8.5 percent, compared with this year’s iPhone 17 Pro Max. The U.S. edition, which relies entirely on dual eSIM and omits the physical SIM tray, is expected to reach 5,425 mAh, up 6.6 percent from the 5,088 mAh capacity of its predecessor. Earlier speculation had placed the top-tier model’s battery slightly lower, making these figures a small upward revision.
Modest numbers backed by efficiency gains
While the capacities still trail the enormous cells packed into some Chinese flagship competitors, real-world endurance is poised to benefit from the more efficient 2-nanometer Apple A20 Pro chip expected to power the series. During testing, the iPhone 17 Pro Max posted longer battery life than most rivals despite its below-average capacity on paper, and Apple appears set to follow the same efficiency-driven approach rather than chasing the highest raw numbers. The generational bump in both battery size and silicon efficiency could translate into a noticeably longer run time for the iPhone 18 Pro Max when it reaches the market.
