Your WhatsApp backup gets stuck on iPhone for a long time? This guide explains why this problem can arise and 7 solutions for this problem.

The good news is that several practical checks can usually get the backup moving again. This article walks through the most common causes first and then the fixes that match them.

Reasons of WhatsApp Backup on iPhone Stuck

Before trying random fixes, it helps to narrow down why the backup is stuck. The most common causes are account, storage, server, network, or app-setting problems.

  • You may not be signed into iCloud.
  • iCloud drive could be turned off or enabled on other devices with the same Apple Account.
  • There is insufficient storage in iCloud.
  • The iCloud servers will be unavailable.
  • Your network connection could be faulty, unavailable, or not working.
  • There may be compatibility issues with WhatsApp.
  • WhatsApp automatic backup feature could be disabled.

Best Alternative to iCloud to Backup iPhone WhatsApp for Free

Sometimes the root cause is not something you can fix immediately. If the Wi-Fi keeps dropping or iCloud remains unreliable, it helps to create another backup path first so the chats are still protected.

  1. Open the program then connect the device to the computer using USB cables. Select “Back up WhatsApp on Devices” from the options on the left.

The article highlights this tool because it covers the backup and transfer tasks people usually need when iCloud is not cooperating. The key points are below.

  • It simplifies the process of transferring WhatsApp data between Android and iOS devices, including moving data from Android to iPhone and vice versa. Mobitrix guarantees the 100% success rate by adopting the most advanced technology.
  • As we shall see shortly, you can also use it to make a complete backup of your WhatsApp data to your computer (FREE). You don’t have to purchase more storage to keep the data.
  • It is designed for local backup workflows. That can reduce the need to rely on cloud storage when backups keep failing.
  • The software is built to work with many iPhone models and recent iOS versions supported by the product.

Other 6 Fixes for WhatsApp Backup Stuck on iPhone

The remaining fixes focus on checking the usual failure points one by one, starting with iCloud access and then moving through storage, server, network, and backup settings.

3.1 Ensure WhatsApp Backup is Turned On

For the backup process to work, make sure WhatsApp is allowed to use iCloud. Here’s how to check.

  1. Open the Settings on the device and then tap on your name at the top.
  2. Scroll down to turn on “iCloud Drive” while making sure that “WhatsApp” is also turned on.

3.2 Check iCloud Storage

A backup can also stall simply because there is not enough storage left. iCloud only includes 5 GB on the free tier, so large WhatsApp backups can hit that limit faster than many people expect. Use the steps below to check how much space is still available.

  1. Open the Settings and then tap on your name.
  2. Tap “Manage Storage” and you will see available iCloud storage space along with detailed information on how the apps on your device are using up your storage.

If you find that you don’t have adequate iCloud storage space for the backup, you can choose to purchase an additional storage plan or delete some data to make room for the backup.

3.3 Check iCloud System Status

Apple’s iCloud service can also be the reason the backup stalls, so it is worth checking the service status before changing device settings. To do that, go to https://www.apple.com/support/systemstatus and look for iCloud Backup.

If there is a green light next to it, then the problem is not the server, but if there is an orange light next to it, there could be a problem with the server. In this case, there is very little you can do other than wait until the servers are back at full strength.

3.4 Check Network Connection

You may also have backup problems if the network connection is weak or unstable. The first test is to switch to another Wi-Fi network; if the issue continues, resetting network settings can help clear bad connection settings before you try the backup again.

  1. Open Settings, go to the reset options in General, and choose “Reset Network Settings”.
  2. Enter your passcode when prompted and then connected to your Wi-Fi networks again before attempting to backup WhatsApp.

3.5 Change WhatsApp Auto Backup Settings

Large backups can take a long time to finish, and daily auto-backup can create a backlog if the previous run is still not done. Changing the schedule to weekly or monthly is a practical way to stop repeated backup attempts from piling up.

  1. Open WhatsApp and then tap on “Settings”.
  2. Tap “Chats > Chat Backup”.
  3. Tap “Auto Backup” to change the frequency to weekly or monthly.

3.6 Delete the Previous Backup and Try Again

Another practical fix is to remove the previous backup and start again. This can help when the earlier backup file is the part that is corrupted or stuck in an incomplete state.

  1. Open the Settings on your device and tap on your name.
  2. Tap “iCloud Storage” and then select “Backup”.
  3. Select the most recent backup and then tap “Delete Backup” to remove the backup.

Summary

Backing up WhatsApp still matters, but iCloud backups can run into account, storage, server, and network problems. The fixes above are meant to help you identify which cause applies and then get the backup moving again.
