Apple's iPhone 17 Pro Max Tops 2025 Battery-Life Test
A CNET battery-life study of 35 US smartphones during 2025 finds Apple and OnePlus as the top brands, with the iPhone 17 Pro Max taking first place overall thanks to efficiency and software optimization despite not having the largest battery (5,088 mAh). The iPhone 17 ties for second with OnePlus 15; Poco F7 Ultra is third, and iPhone 17 Pro fourth. Tests used a 3-hour full-brightness Wi‑Fi video stream and a 45-minute endurance cycle combining gaming, video, and calls; the iPhone 17 Pro Max also led the endurance test, while Pixel 10 and Pixel 10 Pro Fold performed well in that phase. Brand rankings placed Apple first, OnePlus second, followed by Motorola, Samsung, and Google.
