Install iOS 13 Beta for Performance Enhancements
The iOS 13 beta comes with some performance optimizations that could have a huge impact on your day-to-day use.
Specifically, Apple noted that in iOS 13, downloads are 50 percent smaller, Face ID is 30 percent faster, updates are 60 percent smaller, and apps launch twice as fast as they do on iOS 12.
These are all huge improvements, particularly the app launch times and upgrades to Face ID, and they make iOS 13 worth a look, particularly if your device has struggled in these specific areas.
iOS 13 beta also includes a nifty feature called Optimized Battery Charging which is located in the Battery section of Settings.
The feature learns from your daily charging routine and waits to finish charging your device all the way up until you need your device.
This will prevent your battery from sitting at maximum capacity and could extend the overall life of your iPhone's battery.
