How to Stop WhatsApp Calls from Disconnecting on iPhone
Many iPhone 17 users running iOS 26 are experiencing a frustrating issue where WhatsApp calls disconnect automatically 4-5 seconds after the screen locks. This affects both voice and video calls, disrupting communication. Here’s how to troubleshoot and resolve this problem.
Why WhatsApp Calls Disconnect on Locked iPhone
The issue appears to be a compatibility problem between WhatsApp and iOS 26 on iPhone 17, not a hardware defect. When the screen locks, certain system processes may interfere with WhatsApp’s background operation, causing calls to drop. This is specific to the iPhone 17 with iOS 26 and doesn’t affect calls when the device is unlocked.

Network conflicts can cause call drops:
-
Go to Settings > General > Transfer or Reset iPhone > Reset
-
Tap Reset Network Settings
-
Your device will restart and forget saved Wi-Fi networks
2. Disable Do Not Disturb Mode
Ensure Do Not Disturb isn’t interrupting calls:
-
Open Settings > Focus > Do Not Disturb
-
Toggle it Off or configure exceptions for WhatsApp
3. Turn Off Phone Noise Cancellation
This feature can sometimes conflict with WhatsApp calls:
