Why is my iPhone 12 Pro restarting every time it’s left to go to sleep?
I’ve been struggling with a frustrating issue where my iPhone 12 Pro restarts every time I leave it to go to sleep. Whenever the screen is idle and the phone goes into sleep mode, instead of staying in a low-power state, it suddenly restarts on its own. This constant restarting has become a significant inconvenience, as it disrupts anything I leave in progress, such as downloads or apps running in the background. Often, I come back to find my phone stuck in a restart loop or back at the lock screen unexpectedly.
This problem not only affects the device’s performance but also drains the battery faster than usual. It’s baffling because it started happening out of the blue; there were no significant changes or updates that I can recall which might have triggered this issue. Considering the importance of my phone in managing daily tasks, this unexpected rebooting every time it goes to sleep needs a thorough understanding and solution. I’m looking to understand why this issue is occurring and any potential underlying causes that might be contributing to this repetitive restarting.

You might also be experiencing kernel panics or system crashes. To learn more about what’s happening, you could delve into your phone’s crash reports:
- Connect your iPhone to a computer.
- Open macOS Console (Mac) or Event Viewer (Windows).
- Look for logs under System Reports and Diagnostics.
Analyzing these logs can yield insights into specific apps or processes causing the reboots.
A common cause could be an iOS system corruption. Resetting your iPhone’s settings often helps to resolve these kinds of issues without losing your data.
- Go to Settings.
- Then move to General.
- Scroll down and select Reset.
- Choose Reset All Settings – Note, this won’t delete any data but will reset system settings.
If your issue continues, it might require deeper troubleshooting or a clean system installation.
Resetting your iPhone to factory settings is a more drastic but sometimes necessary step if other solutions don’t work. This will erase all content and settings, so ensure your data is backed up:
- Back up your data via iCloud or iTunes.
- Go to Settings.
- Move to General and select Reset.
- Choose Erase All Content and Settings.
After the reset, restore your iPhone and check if the problem persists. This step clears any corrupted data causing restarts.
Frequent restarts due to diagnostics and usage data collection malfunctions can be avoided by disabling this feature:
- Go to Settings.
- Scroll down to Privacy.
- Tap on Analytics & Improvements.
- Turn off Share iPhone Analytics.
Turning off this option stops any erroneous reporting causing your device to restart unexpectedly.
Your iPhone 12 Pro might be restarting every time it enters sleep mode due to software issues. Firstly, check if there are any pending iOS updates. Often, Apple releases updates to fix bugs and glitches. Here are the steps:
- Navigate to Settings.
- Scroll down and select General.
- Tap on Software Update.
- If an update is available, follow the prompts to download and install it.
Updating to the latest iOS can address any known software bugs causing your phone to restart.
Frequent restarts can be attributed to background processes colliding and causing system instability. To mitigate this, try stopping background services and disabling background app refresh:
- Navigate to Settings.
- Tap on General.
- Select Background App Refresh.
- Turn off Background App Refresh.
Additionally, deactivating unnecessary services like Bluetooth and Siri when not in use can reduce background activity, potentially stabilizing your device.
Sometimes, a hardware malfunction could be causing restarts. This is particularly common if the device has been dropped or exposed to water. Check for potential hardware-related issues:
- Examine the iPhone’s exterior for any signs of damage.
- If you suspect physical damage or water exposure, contacting Apple Support or visiting an authorized service center might be necessary.
Ignoring hardware issues can lead to broader problems that software solutions cannot fix.
Another angle to explore is the iPhone’s battery health. Aging batteries can cause erratic behavior, including unexpected restarts. Check battery condition:
- Head to Settings.
- Go to Battery.
- Select Battery Health.
If the maximum capacity is significantly lower than 100% or if Performance Management has been applied, consider replacing the battery.
This issue could stem from a problematic app. Some poorly optimized third-party applications can cause system instability. Start by identifying recently installed apps:
- Close all background apps.
- Delete the apps added just before the issue began.
- Restart your iPhone and observe if the restarting stops.
If the problem persists, you may need to remove more apps and test again.
Looking at a more technical angle, network-related settings might play a role. Resetting your network settings can sometimes resolve issues linked to connections and network configurations:
- Go to Settings.
- Navigate to General.
- Select Reset.
- Tap on Reset Network Settings.
This will reset Wi-Fi networks, passwords, and VPN settings. Reconnect to your networks to test if the restarts continue.
