iFixit Shows Off the iPhone 16's Shocking Battery Removal Process
But the battery is the real star of the show. The iPhone 16 and 16 Plus use a new electrically-releasing battery adhesive that improves the ease and safety of battery replacements. Simply apply a 9-volt charge to the battery, and it can be removed within a few seconds. (Unfortunately, the iPhone 16 Pro and Pro Max do not use Apple's new adhesive.)
