iPhone 15 Pro Max Screen Time shows impossible usage and no app activity

I’m experiencing a serious issue with Screen Time on my iPhone 15 Pro Max.


Screen Time is showing around 43 hours of usage in a single day, which is obviously impossible. The problem is not limited to the total usage time.


The detailed Screen Time report is also incorrect:


  • Screen Time is showing activity almost exclusively for Safari/websites.
  • It shows around 10 hours of usage for each of four different web pages, which is also impossible.
  • There is no Screen Time activity being reported for my installed applications, even though I regularly use them.
  • The Screen Time data therefore does not reflect my actual device usage at all.
  • This issue first appeared while I was running iOS 26. I subsequently upgraded my iPhone 15 Pro Max to iOS 27, but the problem has continued after the update.


I have also already tried the following:


  1. Turned off App & Website Activity in Screen Time.
  2. Restarted the iPhone.
  3. Turned App & Website Activity back on.
  4. Checked Screen Time again, but the issue remained.

At this point, Screen Time is essentially unusable because the reported data is completely inaccurate.


Has anyone else experienced the same issue on iOS 26 or iOS 27? Is there a known fix or another troubleshooting step that can reset/rebuild the Screen Time usage data correctly?

iPhone 15 Pro Max, iOS 27

You may try some of these steps. Please check after each step...


  1. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
    1. Restart the device. That's it.
    2. Still not solved --> Force restart iPhone - Apple Support
  2. If you're using a VPN, disable it and check if the error goes away. Go to Settings > General > VPN & Device Management and turn off any active VPNs. Disabling a VPN only from the iPhone settings may not completely turn it off. To fully disable it, you need to switch it off from the VPN service provider’s app or remove the configuration profile they installed. Only then is the VPN truly off, which can help if it’s causing issues with cellular or Wi-Fi connectivity.
  3. Reset Network Settings: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings: Only network settings are removed.
    1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
    2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
    3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
    4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
  4. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
    1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
    2. You can return settings to their defaults without erasing your content.
    3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
  5. Make sure you have the latest updates installed.
    1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
    2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)


If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
