iPhone 18 Pros: Battery Breakthroughs Still Needed?
16 Sep
Summary
- iPhone 18 Pro Max endured 18 hours 27 minutes, Pro 16 hours 17 minutes.
- iPhone 18 Pro Max beats Samsung, Google phones by significant margins.
- OnePlus 15's 25-hour battery life remains unmatched by iPhones.
The iPhone 18 Pro Max and 18 Pro have been released, promising extended battery life. Testing reveals the iPhone 18 Pro Max achieved 18 hours and 27 minutes of endurance, while the iPhone 18 Pro lasted 16 hours and 17 minutes in real-world web browsing tests.
These results show year-over-year improvements, with the 18 Pro Max lasting 33 minutes longer and the 18 Pro 56 minutes longer than their predecessors. The new iPhones also outperform major Android competitors like the Samsung Galaxy S26 Ultra and Pixel 11 Pro XL.
However, the OnePlus 15 continues to lead in battery endurance, offering an impressive 25 hours and 13 minutes. This significant gap suggests Apple's reliance on conventional lithium-ion batteries has limitations.
To achieve truly multi-day battery life and claim the endurance crown, Apple may need to adopt advanced technologies like silicon-carbon batteries, which offer higher energy density without increasing device bulk.
