There could be multiple reasons and to debug this further, try to capture the packet using BLE sniffer.

1: You might not be handling the connection parameter update from the center.

or,

2: You might be facing the spec violation problem of newer iOS version.

To resolve disconnection due to missing handler for connection update [1], you can try the method I used, It is described here. Or in case of the iOS spec violation [2], you can implement a workaround, mentioned here.

He slightly incorrect it is not a chip level thing. The root cause is actually the crystals on the iPhone which operate slightly out of spec from the BLE specification. You can account for this but increasing your Rx window in your code by setting the accuracy of the LFCLK to 250 or 500.
