Updates often slow down your iPhone, but Apple says this update will speed your phone up. iOS 12 will speed up everything from your app launches to your keyboard and camera.

The new iOS 12 operating system will support all the same devices that iOS 11 runs on, including devices that were released in 2013, like the iPhone 5s. In fact, Apple is focusing its efforts on older devices in particular, making sure they’re still good and speedy so they d on’t slow down over time. This is a big change from Apple reducing CPU performance on old iPhones without telling anyone last year.

We don’t know all the details yet, but Apple promised up to 40% faster app launches, up to 50% faster keyboard display, and up to 70% faster camera performance.

Apple also promised to improve performance under load, when the iPhone or iPad is doing a lot of work. Specifically, Apple promised that the share sheet will appear and apps will launch up to twice as fast when the device is under load.

Apple also said that CPU performance would be better, too. When your iPhone or iPad needs to do a demanding task, the CPU will ramp up to maximum performance mode more quickly to get that work done before lowering its performance to use less battery power to extend your battery life.
