Improve Battery Life
Keeping mobile devices powered is a persistent challenge. As your Apple devices do more and more for you, features like background tasks, Location Services, iCloud syncing, and Background App Refresh can strain a battery. Fortunately, iOS and iPadOS offer some tools that can extend your battery life.
Tame Battery Usage
In Settings > Battery, under Battery Usage By App, apps are sorted by how much power they’ve used, but apps near the top aren’t necessarily wasteful. If you use an app often, it naturally uses more battery.
