iPhone (iOS) Troubleshooting settings
Reset, restart, and diagnose common issues.
- Reset iPhoneReset options let you fix persistent software issues by resetting specific settings (like network or keyboard dictionary) or fully erase the device back to factory defaults.
- Analytics & ImprovementsAnalytics & Improvements controls whether your iPhone automatically sends anonymized crash reports and usage analytics to Apple, and optionally to third-party app developers, to help diagnose problems and improve software.
- Recovery Mode & RestoreRecovery Mode is a special startup state used with a computer running Finder (or iTunes on older systems) to reinstall or restore iOS when an iPhone is frozen, stuck on the Apple logo, or won't update normally.
- Diagnostic LogEvery app crash or system hang on iPhone generates a diagnostic log you can view directly on the device, useful for troubleshooting a misbehaving app yourself or sharing details with a developer or support team.
- Battery Health & ChargingBattery Health & Charging shows your battery's Maximum Capacity as a percentage of its original capacity, its Peak Performance Capability status, and charging optimization options — the key diagnostic info for battery-related complaints.
- Force Restart & Shut DownA force restart or full shut down can resolve a frozen or unresponsive iPhone using a physical button sequence, without needing to reach Settings at all.
- Erase All Content and SettingsErase All Content and Settings permanently deletes everything on the iPhone, including apps, photos, settings, and accounts, restoring it to an out-of-box state, distinct from resetting individual settings categories.
- DFU Mode RestoreDevice Firmware Update (DFU) Mode is the lowest-level restore state available on iPhone, used when the device won't respond to a force restart or standard Recovery Mode, typically requiring a computer with Finder or iTunes.
- Temperature Warnings & OverheatingiPhone displays an on-screen warning and can temporarily limit performance, charging, or camera flash when it gets too hot or too cold, protecting the battery and internal components until it returns to a safe operating range.
- Wi-Fi & Bluetooth Connectivity TroubleshootingA structured set of steps, including toggling Airplane Mode, forgetting a network, and resetting network settings, can resolve most Wi-Fi and Bluetooth connectivity issues on iPhone.
