How to Fix StandBy Mode Not Working on iOS 17

Is StandBy mode not working on your iPhone running iOS 17?

Apple unveiled iOS 17 at WWDC 23, packed with new amazing features. One notable feature in the latest version is the StandBy mode. 

StandBy mode allows you to turn your iPhone into a smart display when charging it in landscape mode.

However, early adopters of iOS 17 BETA encountered issues while using StandBy mode. 

To help, we’ve made a guide for fixing StandBy mode if it’s not working on iOS 17. 

Let’s begin!

1. Restart Your iPhone. 

Restarting your iPhone is the first thing you should do if you encounter issues. This allows your system to reload its resources and resolve temporary errors. 

It should also flush corrupted and cached data from the system memory, giving your OS a fresh environment to operate. 

Here’s how you can restart an iPhone running iOS 17: 

  1. Hold down the Volume Down button and Side button until the ‘Slide to Power Off’ prompt appears. 
  2. Now, drag the slider to the right and wait for 30 seconds. 
  3. Press the Side button afterward to turn on your device.

Once done, try using StandBy mode again to check if the problem is solved.

2. Enable StandBy Mode. 

StandBy mode doesn’t come enabled when you update to iOS 17. This means you’ll have to set up the feature first. 

Follow the steps below to guide you through the process: 

  1. Launch Settings on your iPhone. 
  2. Next, scroll down and tap on StandBy

3. Know How StandBy Works. 

StandBy doesn’t always turn on in iOS 17. For it to work, your iPhone must be in the following conditions: 

  • It must be plugged into the charger. 
  • Your iPhone must be locked. 
  • Your iPhone has to rest on a surface or be docked in landscape mode. 

4. Use MFI-Certified Cables. 

As mentioned above, StandBy only works when your iPhone is charging. However, a generic iPhone charging cable could prevent StandBy mode from working. 

Due to this, we recommend using MFI-certified cables. These cables are specifically made for iPhones, iPads, and iPods and passed Apple’s standards.

If you are using an aftermarket cable, get the original cable that came with your iPhone. 

When buying a charging cable, always look for the MFI logo on the box and only purchase accessories from reputable stores. Better yet, head to the nearest Apple Store and grab an original lightning cable. 

5. Turn Off Low Power Mode. 

Although StandBy mode should work with Low Power mode, we suggest disabling the feature to see if it’s affecting it. 

Since iOS 17 is still in BETA, there could be some conflict between the two features since StandBy mode consumes power while Low Power Mode tries to save power. 

Here’s how you can turn off low power mode: 

  1. Launch Settings on your iPhone. 
  2. After that, scroll down and access the Battery tab. 
  3. Find Low Power Mode and tap the toggle switch to disable it.

The battery indicator should turn green or red, depending on the battery level, when low power mode is disabled. 

6. Check for Software Updates. 

BETA versions of iOS usually receive more updates as Apple prepares the software for the official launch. 

If you encounter an issue, see if there’s a new version available, which could contain a patch for the problem. 

Follow the steps below to update your device: 

  1. Launch Settings on your device. 
  2. Now, tap on General > Software Update
  3. If there’s an available update, tap on Download and Install
Update iPhone


  • Your device can restart several times while installing the update. 
  • Make sure that your iPhone has at least 50% battery before installing updates. It’s best to keep your device plugged into the wall charger to avoid interruptions. 
  • Allow at least 15 minutes for the update to install, especially if it’s a major update (iOS 14 to iOS 15).

Once done, see if StandBy mode works on your iPhone.

7. Reset Your iPhone Settings. 

If none of the solutions above worked, we recommend resetting your iPhone’s configurations. This way, you can ensure that a conflict with your settings does not cause the issue. 

Here’s what you need to do: 

  1. On your iPhone, go to the main menu and open Settings
  2. Now, tap on General
  3. Look for Transfer or Reset iPhone and tap on it. 
  4. Tap the Reset option and select Reset All Settings

  1. Follow the prompts to continue. 


  • Your iPhone will immediately restart upon resetting your network configurations. 
  • It may appear to be stuck in the Apple logo. Wait for the process to complete, which usually takes around 5 to 10 minutes. 

Enter StandBy mode again to check if the features work on your iPhone running iOS 17. 

If the issue persists, we suggest downgrading to an official version of iOS and just wait for the official release of iOS 17. 

That sums up our guide on how to fix StandBy mode if it’s not working on iOS 17.
