iPhone 18 Pro Max Test Shows Much Faster Charging From 0% to 100%
As spotted by the account Ice Universe, the video reveals that the iPhone 18 Pro Max can go from 0% to 100% battery life in as little as 55 minutes with a capable charger, compared to 81 minutes for the iPhone 17 Pro Max. In other words, the iPhone 18 Pro Max can be "fully" charged 26 minutes faster compared to the previous generation (iPhones continue to receive a slow trickle of power even after they show 100% battery life). In line with Apple's advertised claim, the video showed that the iPhone 18 Pro Max can reach 50% battery life in just 15 minutes, down from 20 minutes for the iPhone 17 Pro models.
