Overview

• YouTuber Mrwhosetheboss recorded 13 hours for the iPhone 17 Pro Max versus 11 hours 58 minutes for Samsung’s Galaxy S25 Ultra in a simulated daily-use test.
• The tested unit was the UK variant with a physical SIM tray, and reporting notes the eSIM-only U.S. model includes a slightly larger battery that could extend runtime.
• Last year’s iPhone 16 Pro Max logged about 12 hours 15 minutes in the same test, pointing to a roughly 1–2 hour year-over-year gain for the 17 Pro Max.
• Chinese journalist Geekerwan’s separate mixed-usage trial on physical‑SIM iPhones similarly found the 17 Pro Max lasting nearly two hours longer than its predecessor.
• Apple’s official 35-hour streaming playback figure reflects optimized video tests, whereas these trials used mixed tasks like social apps, productivity, recording, and music streaming that yield shorter but more representative results.
