You’re sharing your iPhone’s hotspot with a friend or a laptop, and it works perfectly—until your phone’s screen goes dark. Suddenly, the connection drops. Frustrating, right?
This is a surprisingly common problem with iPhones running iOS 16 and newer. The hotspot feature is designed to conserve battery, so when your screen auto-locks, the phone may stop broadcasting the hotspot signal. But don’t worry—we’ll go through simple, real-world solutions to keep your hotspot running smoothly.
Quick Checklist to Try First
- Check that Auto-Lock is set to a longer duration or Never
- Ensure your iPhone is charging while using hotspot
- Update iOS to the latest version
- Toggle hotspot off and back on
- Restart your device
Why Your Hotspot Disconnects When Screen Locks
iOS prioritizes battery life. When your screen auto-locks, the system may suspend background services, including the hotspot. Other contributing factors include:
- Low battery: iOS may limit hotspot activity
- Multiple devices connected: Too many connections can trigger automatic disconnections
- WiFi interference: Crowded networks or nearby devices can destabilize your hotspot
This behavior is similar to Android users seeing reconnect loops on crowded public WiFi. The pattern is predictable: your device tries to protect resources, sometimes at the expense of connectivity.
Solution 1: Adjust Auto-Lock Settings
Prevent the phone from sleeping while your hotspot is active:
- Go to Settings → Display & Brightness → Auto-Lock
- Set to Never while sharing your hotspot
- After finishing, restore your preferred Auto-Lock time
Technician insight: This is the simplest and most reliable method. iOS keeps the hotspot active as long as the screen stays on.
Solution 2: Keep iPhone Plugged In
When charging, iOS deprioritizes battery-saving measures. Keeping the iPhone plugged in while hotspotting reduces automatic disconnections.
- Use a wall charger or portable power bank
- Ensure the cable and adapter support data/hotspot usage, not just charging
Solution 3: Limit Connected Devices
iPhones can handle several devices on a hotspot, but too many can trigger automatic drops.
- Disconnect devices not currently in use
- Connect only essential devices to stabilize the connection
Solution 4: Reset Network Settings
Corrupted network settings can lead to unstable hotspot connections.
- Go to Settings → General → Reset → Reset Network Settings
- Confirm reset
- Reconnect hotspot manually
Pro tip: This also resolves issues like iPhone loses internet connection or hotspot refusing to connect.
Solution 5: Update iOS
Apple often fixes hotspot bugs in minor updates:
- Go to Settings → General → Software Update
- Install any available updates
- Restart your iPhone after updating
If This Happens → Do This
- Hotspot drops after auto-lock → set Auto-Lock to Never or stay on charger
- Devices disconnect intermittently → limit connected devices
- Hotspot refuses to reconnect → reset network settings
