Behold! I now crown the iPhone 16 Pro Max as our new smartphone battery life king, kicking the Google Pixel 9 out of its short-lived throne. You won't believe how long the top-tier iPhone 16 lasted on a charge.

Apple claims that the new technology will make it faster and safer for iPhone owners and repair specialists to swap out the battery. It works by “running a low voltage electrical current through the new ionic liquid battery adhesive,” which releases the power pack from its enclosure.

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.
