How far can you go back in the history of calls received on the iPhone?-Why can't you ask the iPhone now?

One of the charms and strengths of the iPhone is that you can understand how to use it without reading the manual. However, even if you think you know it, there must be something you don't understand correctly. In this corner, we will explain in an easy-to-understand manner "why the iPhone can't be asked now". This time, I will answer the question, "How far back can the history of incoming calls on the iPhone go?"

＊＊＊

There is no specific storage period for the incoming/outgoing history displayed on the screen. If the phone number is used with the same Apple ID, you can even go back to the history before the model change.

However, the number of items displayed in "Phone" in iOS 11 is limited to a maximum of 100 items. If the number of records exceeds 100, the records will not be displayed starting with the oldest, so users who frequently use the phone may not be able to view the records even several weeks ago. On the other hand, for users who don't use the phone often, it is possible to check the history even if it is more than a year old.

It is also important to note that what is displayed is not limited to "Phone". Voice calls using FaceTima Audio, as well as phone calls from mobile phone companies (carrier phones), are recorded in the "Phone" app. In addition, third-party applications such as LINE and Skype that use the development framework "CallKit" introduced from iOS 10 can also leave incoming / outgoing history in the "Phone" application.

By the way, if you restore the backed-up data, you can access the deleted incoming/outgoing call history, but it only restores the history at the time of backup. The data of apps other than "Phone" will also be restored, so let's decide carefully.
