On our TikTok rundown battery test, which loops a continuous video until it dies with the display at 50% of brightness, the iPhone 16 Pro Max ran out of juice after 25 hours and 17 minutes.

Via regulatory listings we found that the iPhone 15 and iPhone 15 Plus have 3,349 mAh and 4,383 mAh batteries, respectively. In our tests we found the Plus model performed much better than the standard iPhone 15, giving us a battery life of 14 hours and 14 minutes compared to 11 hours and 5 minutes.

Android 14 runs the show and the Pixel 9 Pro Fold has one of the cleanest versions of the operating system with very minimal bloatware. It's long-lasting too with seven years of software updates and feature drops to come, meaning this phone could last until 2031.
