Samsung’s been coasting for five years with the same 5,000mAh battery, and that’s the whole reason this iPhone 17 Pro Max vs Galaxy S25 Ultra matchup turned into a straight-up loyalty crisis for me. I’ve been team Samsung forever (my S23 Ultra is still going strong), but after two weeks daily-driving both phones, I can’t ignore what Apple just pulled off: a bigger battery (5,088mAh in the eSIM model), a brighter display (3,000 nits vs 2,600), and a zoom camera that’s finally in “Samsung should be worried” territory. I break down the pricing reality check too—$1,199 for the iPhone vs $1,249 for the S25 Ultra—because Samsung is literally charging more while falling behind in key areas like battery progress and screen brightness (even though they make Apple’s panels). Performance-wise, the A19 Pro being faster wasn’t shocking, but the efficiency claims are what make Samsung’s battery situation look even worse. To be fair, Samsung still smokes Apple on AI—photo editing feels like magic, Gemini makes Siri look embarrassing, and Circle to Search is genuinely game-changing. But iOS 26’s “liquid glass” smoothness and Apple’s all-around leap this year forced my conclusion: if you’re in Apple’s ecosystem, 17 Pro Max is a no-brainer; if you need the S Pen, S25 Ultra still makes sense; otherwise, I’d wait for the S26 Ultra because Samsung has to come back swinging.
