Why can't I backup my iPhone to iCloud?

Apple users are allowed to backup iPhone with iCloud automatically or manually. However, whether the iPhone can backup to iCloud or not depends on various factors, including the cloud storage, Internet connection, and the amount of your personal data. If your iPhone fail to backup to iCloud, here are some common causes:

  • Weak and unstable Wi-Fi network. Stable and strong internet connection is required so that the iPhone backup process won't be stuck in the middle.
  • The device doesn't have enough power. iCloud backup takes time, hours and even days, depending on the amount of your iPhone data.
