If you’re using an iPhone 15 Plus and notice it restarting out of nowhere, you’re not alone. For a device that boasts battery power and performance, random reboots or continuous restart loops can be incredibly frustrating.
This blog will walk you through what causes the restart issue in the iPhone 15 Plus, how to troubleshoot it, and when it’s time to seek professional help.
What Does a Restart Problem Look Like?
Here are the common signs that your iPhone 15 Plus is experiencing a restart issue:
- The phone restarts automatically, even when idle
- You see the Apple logo flash, then the screen goes black
- The phone loops between startup and shutdown
- Restarts happen when charging, gaming, or using high-performance apps
These restarts aren’t just annoying—they could be pointing to deeper issues.
Likely Reasons Behind the Restart Problem
The iPhone 15 Plus is powerful, but like any complex device, it’s vulnerable to several potential triggers:
🧠 1. Software Bugs or iOS Issues
If your device started restarting after a recent update, the iOS version might be unstable or improperly installed.
🔋 2. Battery Malfunction
Although the 15 Plus is known for strong battery life, a defective battery or voltage regulation issue could cause power fluctuations and force restarts.
⚙️ 3. Overloaded System
Running too many heavy apps at once—especially poorly optimized ones—can stress the CPU and trigger reboots.
🔌 4. Faulty Accessories
Non-certified charging cables or adapters can deliver unstable current, disrupting the power system and causing the phone to reset.
💥 5. Internal Hardware Issues
If your iPhone 15 Plus has been dropped, exposed to water, or experienced a voltage spike, internal components like the power IC or NAND chip could be compromised.
Troubleshooting Steps to Try at Home
Before rushing to a technician, you can try these safe, Apple-recommended steps:
🔄 Force Restart the Device
- Press and quickly release Volume Up
- Press and quickly release Volume Down
- Hold the Side button until you see the Apple logo
⚙️ Update iOS
Go to Settings > General > Software Update and install the latest version to rule out system bugs.
🔋 Check Battery Health
Navigate to Settings > Battery > Battery Health & Charging. If it shows “Service” or health below 80%, that’s a red flag.
🧹 Remove Problematic Apps
Uninstall any apps that are buggy, outdated, or that you installed right before the issue began.
🔧 Reset All Settings
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won’t erase your content.
