On Saturday, iOS developer Alice Sfeir released the latest version of his SmartBattery jailbreak tweak, the latest being SmartBattery iOS 15.
The iPhone tends to keep a close eye on its battery life throughout the day, and if that sounds like you, then SmartBattery iOS 15 can help you squeeze out every juicy drop of battery life you can get from your device’s battery by setting efficiency preferences that restrict use when not required.
