This year, Apple has seriously ramped up the battery life of its new iPhones. The iPhone 16 Pro Max, for instance, offers some of the best battery life of any smartphone on the market and lasted an average of 16 hours at a time in our review. Now, a new report has put the battery life of Apple’s flagship device under the microscope in a different way, and the results are similarly impressive.In an extensive suite of tests, ChargerLAB examined the iPhone 16 Pro Max’s battery from a variety of angles: temperature while charging, reverse charging a set of AirPods, compatibility with third-party chargers, and more. But the tests that were perhaps the most interesting were those that rated the phone’s wired charging speeds.Here, ChargerLAB measured how much wattage the phone was able to draw upon with a wide variety of chargers made by both Apple and third-party manufacturers. When comparing the results to those that ChargerLAB recorded for the iPhone 15 Pro Max, it’s clear that the iPhone 16 Pro Max can draw far more power from the same charger – in most cases.For instance, this year’s iPhone 16 Pro Max can get 28.39 watts from an Apple 30W charger, compared to 24.55 watts for the iPhone 15 Pro Max, a boost of about 15%. When Apple’s 70W plug is used, the newer phone can take on 30.15 watts compared to 24.93 watts for last year’s device, an increase of almost 21%. That suggests that the iPhone 16 Pro Max should get a noticeable charging boost compared to the iPhone 15 Pro Max. The only exception was using a charger with 20W of power or less, where both phones drew almost identical wattages.Boosting the first hour
