Apps on iOS 12 to start up to 2x faster, including on older iPhones
This is a pretty breathtaking number, given how optimized iOS is already, and we can't wait to put this to the test. That will mean no more waiting and hiccups on older devices, and resources freed on newer iPhones, as well as a gentler impact on battery life. The average numbers Apple cited, compared to iOS 11, is apps launching 40% faster, keyboard coming up 50% quicker, and so on.
The best part is that the new code will bring faster timeframes to aging iPhones, too, such as the camera starting 70% faster. It remains to be seen how the revving up the CPU to the maximum much faster than before will behave on an older battery pack, but given all the throttling controversy, Apple has probably optimized the heck out of the software to do just that.
