Why are my iPad and iPhone not syncing?
Make sure that the date and time settings on your iPhone, iPad, iPod touch, Mac, or PC are correct. Make sure that you’re signed in to iCloud with the same Apple ID on all of your devices. Then, check that you turned on Contacts, Calendars, and Reminders* in your iCloud settings. Check your Internet connection.
How do I get all my Apple devices to sync?
Automatically sync all content: This is the quickest and easiest option. Simply select the “Automatically sync when this [device] is connected” checkbox in the General pane, then turn on syncing for each type of content you want to sync. Your Mac and iPhone or iPad update to matching content whenever you connect them.
How do I know if my iPad and iPhone are synced?
2 Answers. You can tell if you are backing up to iCloud by going to Settings > iCloud > Storage & Backup on your iPad. Look at the bottom of that page and it will indicate when the last backup was. In iTunes, on the Summary tab there is a check box to backup to iCloud.
