How can Apple keep SMS and call records longer?

One:? 1, Apple's mobile phone call records have no specific storage time, but are stored according to the number of call records.

2. Apple's mobile phone call records can reach up to 65,438+000. If the total number of recent calls here is less than 65,438+000 (if you talk to the same person many times on the same day, it's just a call record), then you can find records from a long time ago. If the number of recent calls exceeds 65,438+000, the system will automatically erase the original record and cannot retrieve the record.

3. If the number is less than 100, the specific query method is to open the phone, select the address book, click the call record, and then slide up to query the previous call record.

Two: you can back up SMS and call records!

The backup method is as follows:

1. Just connect your phone to itunes and right-click on the device to select Backup.

2.itools can be used to back up address books, SMS (manual after 5.0) calendars, etc.
