Your iPhone is likely turning off every 5 minutes primarily due to a degraded battery, water damage, or conflicts caused by an app or operating system glitches. This consistent shutdown pattern indicates a fundamental issue preventing stable operation.
Common Reasons Your iPhone Keeps Shutting Down
When your iPhone frequently shuts down, especially in a recurring pattern, it often points to one of the following underlying problems:
1. Degraded Battery Health
A battery that can no longer hold a stable charge is a primary culprit for random shutdowns. As lithium-ion batteries age, their capacity to deliver peak power diminishes. This can cause the iPhone to suddenly power off, particularly during demanding tasks or when the remaining charge is low, because the battery cannot supply the necessary voltage.
- Signs of a failing battery:
- Rapid battery drain.
- Slow performance.
- iPhone shutting down at 20% or 30% battery, or even higher percentages.
- Battery swelling (rare, but serious).
- How to check battery health:
- Go to Settings > Battery > Battery Health & Charging.
- Look at "Maximum Capacity." If it's significantly below 80%, or if "Peak Performance Capability" indicates the battery is degrading, it's a strong sign.
- Solution: A battery replacement is often the most effective fix for this issue. You can schedule an appointment at an Apple Store or an authorized service provider.
2. Water Damage
Even minor exposure to liquids can cause internal corrosion or short circuits within your iPhone, leading to erratic behavior, including frequent shutdowns. Water damage might not always be immediately apparent and can manifest over time as components degrade.
- Signs of water damage:
- Liquid Contact Indicators (LCIs) inside the SIM tray or charging port may turn red.
- Fog under the screen or in camera lenses.
- Unresponsive buttons, speakers, or charging ports.
- Failure to power on, or random shutdowns.
- What to do if suspected:
- Immediately power off the device and do not attempt to turn it back on or charge it.
- Do not use rice or heat to dry it.
- Seek professional assessment from an Apple Store or authorized service provider as soon as possible.
- Solution: Professional repair or, in many cases, device replacement, as water damage can be extensive and difficult to fully resolve.
3. Software Glitches and App Conflicts
Sometimes, a software bug, a corrupted iOS update, or a problematic app can cause your iPhone to become unstable and shut down repeatedly. An app that crashes frequently or consumes excessive resources might trigger a system shutdown to prevent further issues.
- Troubleshooting software-related shutdowns:
- Force Restart Your iPhone: This can clear minor software glitches without erasing data. The method varies by model:
- iPhone 8 or later (including SE 2nd & 3rd gen): Press and quickly release the Volume Up button, then the Volume Down button. Finally, press and hold the Side button until you see the Apple logo.
- iPhone 7/7 Plus: Press and hold both the Volume Down and Sleep/Wake buttons simultaneously until you see the Apple logo.
- iPhone 6s/6s Plus (and older): Press and hold both the Home and Sleep/Wake buttons simultaneously until you see the Apple logo.
- How to force restart your iPhone
- Update All Apps: Ensure all your installed applications are up to date. Outdated apps can have bugs that cause conflicts.
- Update iOS: Make sure your iPhone is running the latest version of iOS. Apple frequently releases updates that include bug fixes and performance improvements.
- Identify and Delete Problematic Apps: If the issue started after installing a new app, or if a specific app crashes frequently, try deleting it to see if the problem resolves.
- Factory Reset (Last Resort): As a final software troubleshooting step, you can restore your iPhone to factory settings. Be sure to back up your device first, as this will erase all data.

Troubleshooting Steps: A Quick Guide
| Problem | Potential Solution |
|---|---|
| Degraded Battery | Check Battery Health, Replace Battery |
| Water Damage | Power Off, Seek Professional Repair/Replacement |
| Software Glitch/App Conflict | Force Restart, Update Apps/iOS, Delete Apps, Reset |
Addressing these common issues systematically can help diagnose and resolve why your iPhone is repeatedly turning off. If simple troubleshooting doesn't work, professional diagnosis is recommended.
