How to Back Up Your WhatsApp Chats on iPhone and Android in Australia

Losing a phone is bad enough. Losing years of WhatsApp chats, family photos, and voice messages with it is worse, and it is completely avoidable. WhatsApp has a built in backup that takes a few minutes to set up, and once it is on, your chats can be restored on a new phone with very little fuss. This guide covers iPhone and Android, step by step, for users in Australia.

Before you start, check two things: you are signed in to the right cloud account, and you have enough free space and a stable Wi-Fi connection. Backups with lots of videos can be large, so a Wi-Fi connection will save mobile data and finish faster.

Step 1: Back up WhatsApp on iPhone with iCloud

On iPhone, WhatsApp backs up to iCloud. First, make sure iCloud Drive is on. Open Settings, tap your name at the top, tap iCloud, and confirm that iCloud Drive is switched on and that WhatsApp is allowed to use it. You also need to be signed in to iCloud with an Apple ID that has enough free storage. If your iCloud storage is full, the backup will fail, so free up space or check your plan before you start.

Next, open WhatsApp, tap Settings at the bottom right, then Chats, then Chat Backup. Tap Back Up Now to make a backup straight away. For ongoing protection, tap Auto Backup and choose a frequency that suits you, such as weekly or daily. If you want videos included, switch on Include Videos, but be aware this makes the backup much larger and slower. Most people are fine backing up videos separately through their photo library and keeping WhatsApp backups to messages and photos.

Wait for the first backup to finish before you switch phones or reset anything. You will see the date and size of the last backup on the Chat Backup screen, and that is your proof that it worked. If the backup stalls, check your Wi-Fi connection and your free iCloud space, then try again.

Step 2: Back up WhatsApp on Android with Google

On Android, WhatsApp backs up to your Google account. Open WhatsApp, tap the three dot menu, then Settings, then Chats, then Chat backup. Tap Google Account and choose the account you want to use. If you do not see your account listed, add it to the phone first under Settings, Accounts, then return to WhatsApp.

Tap Back up to Google Drive and choose a frequency, such as daily or weekly. You can also choose whether backups run on Wi-Fi only or on Wi-Fi and mobile data. Wi-Fi only is the safer choice for large backups. As on iPhone, you can choose whether to include videos. Leaving videos out keeps backups smaller and faster, and you can still save important videos to your photo library separately.

Tap Back Up to run the first backup now. The screen will show progress, and when it finishes it will show the date and size of the latest backup. That confirmation matters: do not wipe an old phone until you have seen a recent backup date here.

Step 3: Restore chats on a new phone

Restoring is straightforward, but the details matter. Install WhatsApp on the new phone, verify the same phone number you used before, and WhatsApp will offer to restore from the backup it finds. On iPhone, it looks in iCloud. On Android, it looks in Google Drive. Tap Restore and wait for it to finish before you start sending messages, because restoring after you have already chatted can create a messy mix of old and new messages.

Two common traps catch people here. First, the phone number must match. A backup tied to your old number will not restore if you verify a different number, so keep your old number active until the restore is done. Second, the cloud account must match. On Android, you need to be signed in to the same Google account, and on iPhone, the same Apple ID with iCloud Drive on. If WhatsApp says no backup was found, the account or number is almost always the reason.

Note that moving between iPhone and Android is a separate process. WhatsApp offers a transfer option during setup on many recent phones, using a cable or a local connection, and it is different from a cloud backup restore. If you are switching platforms, follow the transfer prompts during setup rather than relying on a cloud backup alone, and keep both phones nearby until the transfer is complete.

Step 4: Keep backups healthy and private

A backup is only useful if it is recent. Check the Chat Backup screen every month or so and confirm the date is recent. If auto backup is on but the date is old, check your storage, your Wi-Fi, and whether battery optimisation is pausing WhatsApp in the background. On Android, battery settings that aggressively close apps can delay scheduled backups, so allowing WhatsApp to run in the background helps.

Think about privacy too. A WhatsApp backup stored in the cloud is protected by your cloud account security, so use a strong password and two step verification on your Google or Apple account. Anyone who can sign in to that account could potentially restore your chats, so this step matters as much as the backup itself.

Finally, keep a second copy of what matters most. Export a truly important chat from time to time using the Export Chat option inside the chat itself, and save the file somewhere safe.

Setting up WhatsApp backup takes less time than recovering from losing it. Run the first backup today and let auto backup handle the rest.

Frequently Asked Questions

How often should WhatsApp back up automatically?

Weekly works well for most people, and daily is better if you rely on WhatsApp for work or family coordination. Choose the frequency on the Chat Backup screen and check the last backup date from time to time.

Do WhatsApp backups include videos?

Only if you switch that option on. Including videos makes backups much larger and slower, so many people back up messages and photos in WhatsApp and keep videos in their photo library instead.

Why does WhatsApp say no backup was found on my new phone?

This usually means the phone number or cloud account does not match the old phone. Check that you verified the same number and signed in to the same Google account on Android, or the same Apple ID with iCloud Drive on iPhone, then try again.
