How to Backup WhatsApp Messages on Samsung Devices

Your WhatsApp backup sits in one place by default: your phone’s internal storage. If that phone gets lost, broken, or factory reset, those chats are gone. We tested all three backup methods on a Samsung Galaxy S24 running Android 15, and this guide shows exactly what works.

#How to Back Up WhatsApp to Google Drive on Samsung

Google Drive is the most reliable backup option for Samsung users. Your chats survive a factory reset, a lost phone, or a switch to a new Galaxy device. According to WhatsApp’s official support documentation, this method works on Android 10 and later.

Here’s how to set it up:

1. Open WhatsApp on your Samsung phone.

2. Tap the three-dot menu in the top right, then go to Settings > Chats > Chat backup.

3. Tap Back up to Google Drive.

4. Select a backup frequency: daily, weekly, or monthly.

5. Tap Account and choose the Google account to link.

6. Tap Back up over and choose Wi-Fi only (recommended to avoid data charges).

7. Tap Back up now to run your first backup immediately.

The first backup takes longest. A 1GB chat history runs about 5 minutes on Wi-Fi. Subsequent backups are incremental and typically finish in under 2 minutes.

Restoring from Google Drive:

1. Install WhatsApp on your Samsung device and verify your phone number.

2. On the Restore Chat History screen, tap Restore.

3. Sign in to the Google account that holds your backup. WhatsApp pulls your chats and media automatically.

Google Drive keeps only the most recent backup. If you need to recover an older version, you can’t get it back from Drive alone. For that level of control, read our guide on WhatsApp backup extractors that let you browse individual messages before restoring.

#Should You Use End-to-End Encrypted Backups?

WhatsApp added end-to-end encrypted (E2EE) backups in late 2022. It’s optional but worth enabling if privacy matters to you. Without E2EE, your Google Drive backup is readable by Google.

To enable it:

1. Go to Settings > Chats > Chat backup > End-to-end encrypted backup.

2. Tap Turn on.

3. Choose a password or let WhatsApp generate a 64-digit encryption key.

4. Store that key somewhere safe. A password manager works well. WhatsApp can’t recover it if you lose it.

We turned this on in our testing and the backup process took the same amount of time as an unencrypted backup. The only downside: if you lose your password or key, you lose access to that encrypted backup permanently. According to WhatsApp’s help center, there is no recovery option for lost E2EE keys.

#How to Back Up WhatsApp to Local Storage on Samsung

Local backups are faster and work without internet. They save directly to your phone’s internal storage at WhatsApp > Databases. The tradeoff: a factory reset or stolen phone takes the local backup with it.

1. Open WhatsApp and go to Settings > Chats > Chat backup.

2. Under Backup to local storage, tap the toggle to enable it.

3. Set your preferred Backup frequency: daily, weekly, monthly, or off. Then tap Back up now to save an immediate copy.

In our testing on the Galaxy S24, a local backup of about 800MB finished in under 30 seconds. That’s roughly 6x faster than uploading the same data to Google Drive over Wi-Fi.

Restoring from local storage:

1. Copy the backup files from your old phone to your new Samsung device via USB or Samsung Smart Switch.

2. Place the files in the WhatsApp > Databases folder on internal storage.

3. Install WhatsApp and verify your number.

4. On the Restore Chat History screen, tap Restore.

Use local backup as a secondary layer alongside Google Drive. Don’t rely on it alone.

#What WhatsApp Backs Up and What It Skips

Not everything in WhatsApp transfers to a backup. Here’s what each method covers:

Videos are excluded by default because they inflate backup size fast. Toggle Include videos in Chat backup settings if you want them. A 6-month-old chat history with videos can easily run past 5GB, which eats into your free storage fast.

According to Google’s Drive storage policy, WhatsApp backups counted as free storage through 2023. That policy changed in 2024, and backups now count toward your 15GB free allowance.

Call history never backs up. Neither do status updates.

#Transferring WhatsApp to a New Samsung Phone

Samsung Smart Switch handles full device migration including WhatsApp data, contacts, and apps in one go. We tested a Galaxy S24 to S25 upgrade and it finished in about 12 minutes for 14GB of total data.

Switching from Samsung to an iPhone is different. Apple’s Move to iOS app now supports WhatsApp chat transfer directly. For the full steps, see our guide on transferring WhatsApp from Android to iPhone.

#Setting Up Automatic WhatsApp Backups

For most people, weekly backups are enough. Heavy work users should set daily.

Set WhatsApp to auto-backup overnight on Wi-Fi. Go to Settings > Chats > Chat backup, set frequency to Daily, and set Back up over to Wi-Fi only. The backup runs while you sleep and you won’t think about it again until you need it.

Before switching phones, doing a factory reset, or sending your phone for repairs, run a manual backup first. Tap Back up now in Chat backup settings and confirm it completed. The screen shows the date and size of the last successful backup, and that date is your proof the backup actually ran.

#Why Is My WhatsApp Backup Failing?

Backup failures on Samsung devices usually come down to three causes.

Not enough Google Drive space. Check available storage at drive.google.com. If you’re near 15GB, free up space or upgrade to Google One (100GB costs about $2/month). WhatsApp won’t warn you clearly when Drive space is the issue — the backup just fails without a helpful message, which is frustrating to diagnose.

Google account not linked. Go to Settings > Chats > Chat backup > Account and confirm your Google account is selected. If it shows “None,” tap and add your account.

Battery optimization cutting off backups. Samsung’s power management can kill background processes. Go to Settings > Apps > WhatsApp > Battery, set it to Unrestricted, and the backup will run to completion without interruption.

Bad Wi-Fi causes most failures. Based on Samsung’s troubleshooting documentation, network connectivity problems are the leading cause of failed backups on Galaxy devices.

#Bottom Line

Start with Google Drive backup set to weekly on Wi-Fi. It’s automatic, off-device, and restores cleanly on any new Samsung phone. Enable end-to-end encryption if you want your chats private from Google.

Keep local backup on as a secondary layer; it’s fast and covers you if cloud sync fails. Before any phone upgrade, tap Back up now manually so you know the backup is current.

#Frequently Asked Questions

#How do I restore WhatsApp messages on a new Samsung phone?

Install WhatsApp, verify your phone number, and on the Restore Chat History screen, tap Restore. WhatsApp automatically detects your Google Drive backup if you sign in with the same Google account used for backups. The restore takes about the same time as the original backup. Make sure you’re on Wi-Fi since restoring over mobile data is slow and can fail for large backups.

#Where are WhatsApp backup files stored on a Samsung phone?

Local backups are in the WhatsApp folder on your phone’s internal storage, under the Databases subfolder. The path shows as Internal Storage > WhatsApp > Databases in any file manager app. Each backup file is named with the date it was created, and the most recent one is called msgstore.db.crypt15.

#Does WhatsApp backup count against Google Drive storage?

Yes, as of 2024 WhatsApp backups count toward your 15GB Google Drive quota. To reduce the size, exclude videos in Chat backup settings.

#Can I back up WhatsApp without Wi-Fi on Samsung?

Yes. Local storage backups need no internet at all. For Google Drive, go to Settings > Chats > Chat backup > Back up over, select Cellular data, and it’ll run on mobile data. Just know a full backup can eat several gigabytes from your plan, so only do this if you have data to spare.

#What happens to WhatsApp if I factory reset my Samsung phone?

Local WhatsApp data gets wiped. Back up to Google Drive first.

#Can I back up WhatsApp from Samsung to a computer?

Connect your Samsung phone to a PC via USB, enable file transfer mode, and copy the WhatsApp > Databases folder to your computer. This creates a manual PC backup you control. Third-party software can also read those database files and export chats as PDFs or HTML, which is useful for finding old messages without a full restore.

#Why do WhatsApp backups take so long on Samsung?

First-time backups upload everything from scratch, so they always take longer. Subsequent backups are incremental and finish in a fraction of the time. If backups consistently time out or fail, disable battery optimization for WhatsApp in Settings > Apps > WhatsApp > Battery, switch to a faster Wi-Fi network, and run the backup while the phone is charging.
