Last call mobile number lost after iPhone X died during my conversation

Hi,

I find absurd that iPhone doesn't save the last calling number in the call log section if the battery dies during the conversation. I was able to see the caller's number during the call, but after I charged my battery's phone, his number wasn't saved in the call log.

He didn't called me back and I am very upset, he might thought that I have closed the phone while we have talked.

Honestly, aren't you planning to fix this? At least twice this has happened to me and I don't have the possibility to see who was calling me, as it's a company-owned phone and not private.
