iPhone 16 lock screen stays illuminated during sleep

Lock screen stayed illuminated during my sleep


Hey everyone, during my sleep I caught my iPhone 16 27.2 being awake for the extended period of time.


It was laying on the opposite side of my bed, wasn't charging and I wasn't interacting with it at all, and I don't have Always On display turned on, nor Raise to Wake, Tap to Wake, etc.


I woke up twice and caught the screen illuminated thinking it was some notification that appeared.


Has anyone experienced anything similar?


Got quite concerned.


The battery consumption confirms what I saw - 32% of battery usage, and more than normal battery drainage during sleep hours.

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.

You said that:

  • The iPhone was not charging.
  • No notifications appeared.
  • Always On Display is off.
  • Raise to Wake is off.
  • Tap to Wake is off.
  • The device was lying untouched on a bed.


Then the illuminated screen could still be explained by several normal iPhone behaviours:


  1. A notification arrived and disappeared before it was noticed
    1. Notifications can briefly wake the display and then dim again.
    2. If the user woke up moments later, they may have missed the actual notification banner.
  2. Attention Aware Features
    1. On Face ID iPhones, the TrueDepth camera can occasionally detect a face or movement in low light and interact with display behaviour.
    2. This is less likely if the phone was across the room or facing away.
  3. Background system activity
    1. iOS occasionally wakes the display for certain system-level events, such as software updates, carrier settings prompts, emergency alerts, security-related notifications, or accessory interactions.
    2. These events are uncommon but possible.
