Does your WiFi turn off by itself without any action?
This issue is usually caused by system settings, battery optimization, or software glitches.
Here’s how to fix it quickly.
Why WiFi Turns Off Automatically
If your WiFi keeps turning off on its own, the most common causes are:
- Battery saver or power management features
- System optimization settings
- Software bugs after updates
- Conflicting network settings
Quick Fixes to Try First
1. Disable Battery Saver Mode
Power-saving features often turn off WiFi to extend battery life.
👉 Turn off battery saver and check if WiFi stays on.
2. Turn Off Adaptive Connectivity (Android)
Some Android devices automatically manage network usage.
Go to:
Settings → Network → Adaptive Connectivity → Off
3. Disable WiFi Assist / Smart Switch
Your phone may switch between networks automatically.
👉 Turn off:
- WiFi Assist (iPhone)
- Smart Network Switch (Android)
4. Check Automation or Routines
Some phones have automation features that control WiFi.
👉 Check:
- Routines / Automation settings
- Third-party apps controlling WiFi
