All of the iPhone 15 and iPhone 15 Pro models feature a new battery health setting that prevents the devices from charging beyond 80% at all times...
I limit my laptop battery charge to 80% with a third party software tool. Laptops can generally bypass the battery and directly power themselves from the wall.
Does this new 80% battery limit setting imply that the new iPhones are able to do the same? Implication would be less battery wear while docked on a desk/in a car or due to long “AAA” gaming sessions, since it will draw power direct from the wall rather than using the battery as a middleman.
Alternatively, this just means it will keep draining/charging to keep it at a steady 80%, with the battery still fully involved with providing power to the phone.
