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.

The iPhone 16 family has much bigger batteries than its predecessor, with the iPhone 16 Pro growing by almost 10% versus the iPhone 15 Pro.

Already on X, users moaned that they “regret updating” since the update is supposedly “killing” their phone battery.
