Turn on ultra power saving mode—and suddenly your Wi-Fi starts acting up? Pages won’t load. Apps disconnect. Everything slows down or just stops.
You’re not alone. This is a common issue on both Android and iPhone. The good news? It’s usually easy to fix.
Try this first: most connection drops happen because your phone aggressively limits background activity. Fix that, and Wi-Fi usually stabilizes immediately.
Quick Fix (Start Here)
- Turn OFF ultra power saving mode temporarily
- Reconnect to your Wi-Fi network
- Disable “Restrict Background Data”
- Allow Wi-Fi usage during power saving mode
- Restart your phone (this usually fixes it instantly)
Why This Problem Happens
Ultra power saving mode is designed to extend battery life as much as possible. To do that, your phone limits background processes, sync activity, and even network usage.
Here’s the issue: Wi-Fi needs consistent background communication to stay stable. When your system cuts that off, the connection becomes unreliable—or drops entirely.
Some devices go even further by:
- Turning off Wi-Fi when the screen is off
- Blocking apps from maintaining connections
- Switching network priority aggressively
This is why the problem appears suddenly right after enabling power saving mode.
Step-by-Step Fixes
Allow Wi-Fi During Power Saving Mode
Most people skip this step.
- Go to Settings
- Open Battery or Power Saving settings
- Find “Allowed apps” or “Exceptions”
- Enable Wi-Fi or allow key apps to run in background
This prevents your system from cutting off the connection.
Disable Wi-Fi Sleep Restrictions
- Go to Settings → Wi-Fi
- Tap Advanced settings
- Find “Keep Wi-Fi on during sleep”
- Set it to “Always”
This keeps your connection alive even when the screen is off.
Turn Off Data Saver (If Enabled)
Power saving and data saver together can break connectivity.
- Go to Settings → Network & Internet
- Tap Data Saver
- Turn it OFF or allow unrestricted access for key apps
Reset Network Connection
If things still feel unstable, reset it.
- Go to Settings → System
- Select Reset options
- Tap “Reset Wi-Fi, mobile & Bluetooth”
This clears hidden conflicts instantly.
Check App Restrictions
Some apps get blocked individually.
- Go to Settings → Apps
- Select your main apps (browser, messaging, etc.)
- Tap Battery
- Set to “Unrestricted” or “Not optimized”
This ensures stable connectivity.
If It Still Doesn’t Work
If the issue continues, something deeper might be causing it.
- System bug: Some updates break power-saving behavior
- Aggressive OEM settings: Brands like Xiaomi, Samsung, or Oppo may override standard Android behavior
- Network switching issues: Your phone may struggle switching between Wi-Fi and mobile data
If your connection also drops when switching networks, check this related fix:
Mobile data stops when switching network bands
That issue is surprisingly connected on many devices.
Extra Tips to Prevent This Issue
- Avoid using ultra power saving mode unless necessary
- Keep your system updated (bug fixes matter)
- Whitelist important apps from battery optimization
- Use standard power saving instead of ultra mode
- Restart your device once every few days
Small habits make a big difference.
