My iphone se 2020 keeps dropping calls after iOS 16.5 Update

If the issues you have described are a direct result of the iOS 16.5 update, it is highly likely that a substantial number of users who have performed the software upgrade are encountering a similar problem.

Based on my understanding and experience, it is highly unlikely that iOS updates would introduce issues that affect the day-to-day functioning of the device. iOS updates are typically designed to enhance performance, address security concerns, and introduce new features, rather than causing operational difficulties.

Without a precise understanding of the underlying issue, it may be challenging for forum members to provide targeted solutions to the difficulties you are encountering.

If you are experiencing intermittent silence or drop or the call itself is disconnected during voice calls on your iPhone, there are a few things you can try to fix the issue:

1. Poor signal strength can cause dropouts or silence during a call. Try moving to an area with better reception or switching to a different network if possible.
2. Restart your iPhone --> Restart your iPhone, iPad, or iPod touch - Apple Support
3. Force Restart your iPhone --> Force restart iPhone - Apple Support)
4. This may help too. Go to Settings > General > Transfer & Reset > Reset > Reset Network Settings.
   1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
   2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or Remove configuration profiles on iPhone in this guide.
   3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
   4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
5. Check if there is a software update available for your iPhone. Go to Settings > General > Software Update.
6. Check if your audio is not connected to external Bluetooth speakers.
7. Few other reasons why your device keeps Muting / Dropping / Disconnecting Calls or encountering Call Failed.
   1. Your device's cellular signal Is weak.
   2. It's Raining (Cats & Dogs) in your area or in the area where your device is hooked.
   3. The Cell Tower is Overloaded / Heavy Traffic (Telecommunication)
   4. You've misunderstood your signal strength
   5. You are moving and the signal weakens while changing from one tower to another
8. Other culprits may include the following:
   1. Bad Weather: Precipitation can leak into phone cable lines and cause disruptions. Lightening, even at a distance, can disrupt the connection.
   2. Wireless interference: Power lines, radio, or television. transmitters, transformers, and other electronic devices may cause noise on the phone line. --> Resolve Wi-Fi and Bluetooth issues caused by wireless ...
   3. DSL services: The high-frequency signals coming from DSL (digital subscriber line) devices sharing the phone line can create problems for other technology connected to the line.
9. Try to turn on Airplane mode, wait for 10-15 secs, and turn off airplane mode.
10. Check the health of your device's Battery. Change the battery if the battery health is below 80%
11. Take the SIM out and Put it back again, Change your SIM, if it is damaged
12. Time to contact your Carrier / Change if required

Hello, please go to this thread and see if the advice offered by the OP fixes the issue: iPhone 11 Call Drop FIXED - Apple Community

Please leave feedback in the above thread if the issue was fixed, or not, by following the advice of the OP.

I too face the issue and no solution has worked yet.

I too am having calls drop after this update. Every call (incoming or outgoing) despite where I am located -home, work, WiFi, different cell towers, etc. Calls last 3-5 minutes then disconnect. It is beyond frustrating. The issue is negatively affecting my work and personal life. When is the next update being released to correct the problem?

Trying the fix posted for iPhone 11 (link posted above) = turn off Siri Call Hang Up.

After deactivating siri call hang off option in accessibility, call drop issue got solved. Thanks to the person who suggested this remedy.

Turning off the Call Hang Up option in Siri & Search resolved the orobkem
