**The iPhone 17 Pro Max: The Sovereign of Smartphone Batteries**
The iPhone 17 Pro Max has risen to prominence as a champion in the realm of smartphone battery capability, as evidenced by multiple battery life evaluations, including one performed by renowned tech reviewer Mrwhosetheboss. In a simulated usage assessment, the iPhone 17 Pro Max surpassed its rivals, enduring an extraordinary 13 hours before needing a recharge. In comparison, Samsung’s Galaxy S25 Ultra lasted 11 hours and 58 minutes.
### Battery Specifications and Capability
The assessment was conducted using the UK variant of the iPhone 17 Pro Max, which includes a physical SIM tray. Interestingly, the eSIM-exclusive model offered in the United States and certain markets is fitted with a larger battery, presumably increasing its runtime by an additional half hour or more.
While the iPhone 17 Pro Max took the lead, the entire iPhone 17 lineup, comprising the iPhone Air models, exhibited commendable battery efficiency. The iPhone Air ran for 7 hours and 18 minutes, followed by the standard iPhone 17 at approximately 10 hours, and the iPhone 17 Pro shortly after. Last year’s flagship, the iPhone 16 Pro Max, also delivered strong results, lasting 12 hours and 15 minutes, showcasing a remarkable year-over-year enhancement in battery performance with the new release.
### Real-World Usage Compared to Official Specifications
Apple asserts that the iPhone 17 Pro Max can deliver up to 35 hours of video playback. Nevertheless, this figure derives from controlled circumstances that may not represent average daily use, which frequently includes more demanding activities beyond mere video streaming. The gap between the 13 hours recorded in practical testing and the 35-hour assertion highlights the distinction between optimal conditions and typical operation.
### Comparative Analysis
The battery life evaluation executed by Mrwhosetheboss encompassed a range of tasks, including social media interaction, productivity activities, video capturing, and music playback. A like assessment by Chinese tech journalist Geekerwan, which also focused on the physical SIM tray versions of the iPhones, indicated even more significant enhancements. The 17 Pro Max lasted almost two hours longer than its predecessor, while the standard iPhone 17 closely aligned with the endurance of the iPhone 16 Pro Max.
### Conclusion
The iPhone 17 Pro Max has cemented its position as the supreme smartphone battery leader, demonstrating remarkable progress in battery technology and performance. With outstanding longevity in practical use and significant advancements over prior models, it establishes a high benchmark for competitors in the smartphone arena.
