iPhone (iOS) System settings
Keep your device current and configure core system behavior.
- Software UpdateSoftware Update keeps iOS current with the latest security fixes, features, and app compatibility. You can update wirelessly, overnight while charging, or via a computer.
- BatteryThe Battery screen shows your battery's current health and charging behavior, breaks down which apps used the most power recently, and includes Low Power Mode for stretching a low charge further.
- Automatic UpdatesAutomatic Updates, found inside Software Update settings, controls whether iOS downloads and installs new versions on its own overnight — while charging and on Wi-Fi — without you needing to tap through it manually.
- Update HistoryUpdate History, found on the General → About screen, lists every iOS and iPadOS version that has ever been installed on this specific device, along with the date each one was installed.
- Beta UpdatesBeta Updates lets you opt an iPhone into Apple's Developer or Public Beta program directly from Software Update settings, so it receives pre-release iOS versions ahead of the general public release.
- Rapid Security ResponsesRapid Security Responses deliver urgent security fixes between full iOS releases, installing quickly and, unlike major updates, without requiring a full device restart in most cases.
- Carrier Settings UpdateCarrier Settings Updates are small packages issued by a mobile carrier to improve network performance, enable new features like VoLTE or Wi-Fi Calling, and fix connectivity bugs, independent of iOS software updates.
- App Store Automatic App UpdatesSeparate from iOS software updates, the App Store has its own setting for automatically installing new versions of installed apps as developers release them.
- Update iPhone via ComputerAs an alternative to updating over the air, iPhone can be updated by connecting it to a Mac with Finder or a Windows PC with iTunes, which downloads and installs the update via a wired or Wi-Fi connection to the computer.
- Security-Only Updates for Older DevicesApple sometimes continues issuing security-focused updates for older iPhone models that can no longer run the newest major iOS version, keeping them protected without adding new features.
