iPhone 18 Pro Max and 18 Pro battery life tested — the results are surprising
While the iPhone 18 Pro and iPhone 18 Pro Max battery life results are in. While they beat out many Androids, the year-over-year gains could've been better.
Apple's iPhone 18 Pro Max and iPhone 18 Pro showcase impressive battery life, outperforming their predecessors and many Android rivals. The iPhone 18 Pro Max boasts an impressive 18 hours and 27 minutes of battery life, while the iPhone 18 Pro lasts 16 hours and 17 minutes. Despite the emphasis on the new A20 Pro chip's power efficiency, the gains are modest, with the iPhone 18 Pro Max outlasting the iPhone 17 Pro Max by only 33 minutes—a 3.1% increase.
The iPhone 18 Pro edges out the iPhone 17 Pro by 56 minutes, representing a 6.1% improvement. When compared to rival Android phones, the iPhone 18 Pro Max bests the Galaxy S26 Ultra and Pixel 11 Pro XL, outlasting them by 1 hour and 47 minutes and nearly 4 hours, respectively. The smaller iPhone 18 Pro trails these flagships by a smaller margin, but it remains competitive against them.
However, the OnePlus 15 stands out as the battery life champion with an incredible 25 hours and 13 minutes of endurance, thanks to its massive 7,300 mAh silicon-carbon battery. While Apple's new A20 Pro chip offers significant efficiency gains, the continued reliance on lithium-ion batteries limits the iPhone's ability to achieve multi-day battery life like the OnePlus 15.
To truly excel in endurance, Apple must explore silicon-carbon battery technology, which provides higher energy density without adding bulk and maintains the slim profiles users expect. For now, Apple seems to have edged out Samsung and Google in terms of battery life, but adopting silicon-carbon battery technology is crucial to capturing the overall endurance crown.
