Overview of Standby Mode in iOS 17

Standby Mode is an enhanced version of the existing Auto-Lock feature which turns off your iPhone’s display after a set period of inactivity. With Standby Mode, iOS 17 goes a step further and temporarily disables some system processes and components to conserve battery power.

When Standby Mode is activated, your iPhone’s display, CPU, networking features, and other select hardware are powered down. Incoming calls and notifications still light up the display and sound alerts. But otherwise, your iPhone remains dormant until you press the Side button or tap the screen to wake it up. This allows the battery to drain much slower compared to normal Auto-Lock.

Key Features of Standby Mode

  • Darkens display and disables touch input after period of inactivity
  • Suspends CPU, cellular data, WiFi networking to reduce power draw
  • Incoming calls and unread notifications still light up screen
  • iPhone wakes instantly when Side button is pressed or screen is tapped
  • Standby settings can be customized to user needs

Standby Mode requires an iPhone model with an M2 chip or later running iOS 17. It’s designed to complement existing Battery Saving Modes by further extending battery life when you don’t need constant access to your iPhone. For example, Standby Mode is ideal when sleeping, watching a movie, reading a book, attending a long meeting, or any situation where you won’t use your iPhone for an extended time period.

Troubleshooting Tips for Fixing Standby Mode

If you’ve updated your compatible iPhone to iOS 17 but still can’t get Standby Mode to work properly, try the following troubleshooting steps:

1. Check Compatibility Requirements

Make sure that your iPhone model and iOS version are compatible with Standby Mode:

  • iPhone Models: Standby Mode requires an iPhone model with an M2 chip or later. This includes the iPhone 14, iPhone 14 Plus, iPhone 14 Pro, iPhone 14 Pro Max, and newer. Older iPhone models are not supported.
  • iOS Version: Your iPhone needs to be updated to iOS 17 or later. Standby Mode is not available on earlier iOS versions.

If your iPhone doesn’t meet these requirements, Standby Mode will not activate. You will need an eligible iPhone running iOS 17.

2. Confirm Standby Mode is Enabled

Go to the Settings app → Battery → Standby Mode and check that Standby Mode is toggled ON. If the toggle switch is grayed out or you don’t see a Standby Mode option, your iPhone likely doesn’t support the feature.

Additionally, check that Low Power Mode is disabled, as it takes precedence over Standby Mode.

3. Use Proper Activation Method

To manually activate Standby Mode, follow these steps:

  1. Connect your iPhone to a power source (wall charger or wireless charger). Standby Mode only works when the battery is charging.
  2. Place your iPhone in landscape orientation at an inclined angle, neither completely upright nor flat.
  3. Lock the screen by pressing the Side button or allow the display to auto-lock.

Once activated properly, your iPhone’s screen will darken to save power, the TrueDepth camera and display will turn off, and battery life will be preserved. The screen will light up for incoming calls and unread alerts.

If you are already meeting the above conditions but Standby Mode does not turn on, try adjusting your iPhone’s inclined angle or reconnecting the power source.

4. Adjust Standby Mode Settings

Customize Standby Mode with these settings for best battery life savings:

  • Auto-Enable: Keep this on so Standby Mode starts automatically when conditions are met. Turn off to activate manually only.
  • Turn On At: Set a bedtime schedule if desired, so Standby turns on during your normal sleeping hours.
  • Turn Off At: Set a wake up schedule to disable Standby when you start your day.
  • When Charging: Choose if Standby should activate when charging with a cable, wireless charger, or both.
  • Disable For: Select any apps that should not activate Standby when in use, like your alarm clock.

Tweak as needed to match your usage patterns for optimal battery efficiency.

5. Restart Your iPhone

If Standby Mode is enabled but not working correctly, try restarting your iPhone:

  1. Press and hold the Side button and either Volume button until the power off slider appears.
  2. Drag the slider to turn off your iPhone.
  3. After 30 seconds, press and hold the Side button again until you see the Apple logo to restart your iPhone.

Restarting will clear any glitches and resets all systems to their default state.

6. Disable and Re-Enable Standby Mode

Go back into Settings → Battery → Standby Mode. Toggle OFF Standby Mode, wait a few seconds, then toggle it back ON again.

Disabling and re-enabling Standby often resolves minor system bugs that are interfering with Standby activation.

7. Update to Latest iOS Version

If you are still experiencing issues, make sure your iPhone is updated to the latest iOS version available. Apple continuously releases software updates to fix bugs and improve performance.

Install the newest iOS update (Settings → General → Software Update) to see if that resolves any problems with Standby Mode activation. The latest update may contain a fix specific to Standby.

8. Reset All Settings

If the above steps don’t work, try resetting all system settings on your iPhone:

  1. Go to Settings → General → Reset.
  2. Tap Reset All Settings (this won’t erase any data or content).

Resetting to factory settings often resolves bugs caused by changes in settings and restores services like Standby to normal operation. You’ll just need to reconfigure any customized settings afterwards.

9. Use iOS Repair Software

For recurring or persistent issues activating Standby Mode, specialized iOS repair software like Tenorshare’s ReiBoot can help. This tool fixes all types of iOS problems, crashes, and bugs by repairing the core system files and settings.

ReiBoot will scan your iPhone’s firmware and restore corrupted system files, configuration issues, and other problems that may prevent Standby from working properly. It offers a simple solution for quickly getting Standby Mode and other features functioning again normally.

When to Take Your iPhone for Professional Repair

If you still can’t get Standby Mode to activate after exhausting all standard troubleshooting methods, it’s time to take your iPhone to an Apple store or authorized service center.

Technicians have additional tools and diagnostics to identify any underlying hardware or software faults preventing Standby from working properly. For example, they can:

  • Connect your iPhone to external devices to test components and functions.
  • Run Apple diagnostics to analyze logs and pinpoint system issues.
  • Replace any damaged or malfunctioning parts like the battery, logic board, etc.
  • Completely restore your iPhone firmware as a last resort if unrecoverable software problems exist.

Don’t attempt any do-it-yourself iPhone hardware repairs, as this can void your warranty. Qualified, professional technicians can safely handle any advanced troubleshooting and repairs needed to get Standby Mode functional again.


Standby Mode is a game-changing feature for extending your iPhone’s battery life when you need it most. Following the troubleshooting tips above should help get Standby working properly in iOS 17. Check your iPhone model and iOS version, enable Standby Mode, activate it correctly, adjust settings, restart your iPhone, reset all settings, update iOS, and use software repair tools as needed.
