iphone calendar freezes and/or runs slow

I’ve seen several complaints about iPhone calendars running slow, messing with dates, freezing, etc. Seems to have started with the last major update. I’ve tried various fixes mentioned in help groups. Nothing works. Next step will be to delete and reinstall the app. I’d appreciate any suggestions.

Hi there jwmansour6o6,


We understand that you are having issues with the Calendar app on your iPhone. We’d like to help however we can. 


To confirm, do other apps perform as expected? Do you sync your calendars with iCloud or another account? Does this happen when using a specific calendar or with any calendar?

Set up multiple calendars on iPhone


Let’s also ensure your iPhone is fully updated to the latest version, 15.2.

Update your iPhone, iPad, or iPod touch


If this continues after updating your iPhone, please provide more information on exactly what is happening in the Calendar app.


Cheers!
