Don’t Lose Everything: Back Up Your Phone Before You Reset It
Factory resetting your phone wipes it completely clean — contacts, photos, apps, messages, all of it gone in seconds. It’s the digital equivalent of torching your house to get rid of a wasp nest. Effective, sure, but catastrophic if you haven’t saved what matters first.
Whether you’re resetting to fix a stubborn software bug, selling your device, or handing it down to a family member, knowing how to backup your phone before a factory reset isn’t just smart — it’s essential. The good news? It takes less time than you probably think.
This guide walks you through exactly what to save, how to save it, and what most people forget until it’s too late.
What Actually Gets Deleted in a Factory Reset
A lot of people assume the cloud has already saved everything automatically. Sometimes that’s true. Often, it’s not.
Here’s what a factory reset typically erases:
- All photos and videos stored locally on the device
- Text messages and call logs
- App data and in-app progress (game saves, settings, etc.)
- Downloaded files and documents
- Wi-Fi passwords saved on the device
- Installed apps and their configurations
- Authenticator app tokens (this one catches people off guard)
Your Google or Apple account itself won’t be deleted — that lives on their servers. But anything stored only on the physical device? Gone.
How to Backup Your Phone Before a Factory Reset: Android vs iPhone
The process differs depending on whether you’re on Android or iOS, so let’s cover both properly.
Backing Up an Android Phone
Android gives you a few different routes, and using more than one is wise.
Option 1: Google One Backup (built-in)
- Open Settings on your Android device
- Tap Google, then Backup
- Make sure Back up to Google Drive is toggled on
- Tap Back up now and wait for it to complete
This backs up app data, call history, contacts, device settings, and SMS messages. It does not back up photos by default unless you also use Google Photos.
Option 2: Google Photos for media
Open Google Photos, go to your profile icon, and tap Photos settings → Backup. Turn backup on and wait until the sync completes. You’ll see a message confirming everything is backed up. Don’t reset until you see that confirmation — a partially synced library is a painful halfway point.
Option 3: Manual transfer via USB
Plug your phone into a computer, open the device in File Explorer (Windows) or Android File Transfer (Mac), and copy your DCIM folder, Downloads, and any other folders you want to keep. This is the most reliable method for media because it doesn’t depend on internet speed or cloud storage limits.
Backing Up an iPhone
Apple gives you two main options: iCloud and your computer. Both work well; the right choice depends on your storage situation.
Option 1: iCloud Backup
- Connect to Wi-Fi (iCloud backups won’t run on mobile data by default)
- Go to Settings → [Your Name] → iCloud → iCloud Backup
- Tap Back Up Now
- Keep the screen on and stay connected until the backup finishes
iCloud backups include your app data, device settings, messages, and purchase history. Photos back up separately through iCloud Photos — check that it’s enabled under Settings → [Your Name] → iCloud → Photos.
One catch: the free iCloud plan only gives you 5GB. If your phone has years of photos on it, you’ll likely need to either pay for more storage or use the computer method instead.
Option 2: Backup to Mac or PC
- Connect your iPhone with a USB cable
- On a Mac (macOS Catalina or later): open Finder, click your iPhone in the sidebar, and select Back Up Now
- On a PC or older Mac: open iTunes, click the device icon, and choose Back Up Now
This creates a full local backup — faster than iCloud and doesn’t eat into your storage plan. If you want it encrypted (which saves passwords and health data too), tick the Encrypt local backup option and set a password you’ll actually remember.
The Things Most People Forget to Back Up
Standard backups don’t catch everything. Here are the items that commonly get lost:
Two-Factor Authentication Apps
If you use Google Authenticator, Authy, or Microsoft Authenticator, your 2FA codes are tied to that specific device. Wiping the phone without transferring them first can lock you out of your email, bank accounts, and more.
Before resetting, transfer your authenticator accounts to a new device or print out backup codes for every service that uses 2FA. Authy handles this more gracefully than Google Authenticator, which is worth noting if you switch apps.
WhatsApp and Other Messaging Apps
WhatsApp stores messages locally and through its own backup system — not through Google or iCloud by default. To back it up:
- Android: Open WhatsApp → Settings → Chats → Chat backup → Back Up
- iPhone: Open WhatsApp → Settings → Chats → Chat Backup → Back Up Now
Other messaging apps like Telegram offer their own export options. Signal is more complex — it requires a manual device-to-device transfer.
Downloaded Music and Podcasts
Offline content from Spotify, Apple Music, or podcast apps will need to be re-downloaded after the reset. That’s fine if you have a good connection, but worth knowing in advance.
Saved Game Progress
Many mobile games don’t automatically sync to the cloud. If you’re deep into a game, check whether it supports Google Play Games (Android) or Game Center (iPhone) for cloud saves before you assume your progress is safe.
How to Verify Your Backup Actually Worked
This step is easy to skip, and it’s where people get burned. Don’t just assume the backup ran — confirm it.
| What to verify | How to check (Android) | How to check (iPhone) |
| Google / iCloud backup | Settings → Google → Backup — check timestamp | Settings → [Name] → iCloud → iCloud Backup — check date |
| Photos synced | Google Photos → Profile → Backup status | Photos app → scroll to very bottom for sync status |
| Contacts saved | Log into contacts.google.com from a browser | Log into iCloud.com and check Contacts |
| WhatsApp messages | Check Google Drive → Storage to see WhatsApp backup | Check iCloud Drive for WhatsApp backup folder |
If the timestamp on your backup is days old, run a fresh one before you proceed. Cloud backups often pause when the screen locks or when you switch off Wi-Fi.
A Sensible Order of Operations Before You Reset
Doing things in the right sequence matters. Here’s a clean checklist to follow:
- Charge your phone to at least 80% (a dead battery mid-backup is painful)
- Connect to a reliable Wi-Fi network
- Transfer 2FA authenticator accounts to another device or save backup codes
- Back up WhatsApp and any other messaging apps you care about
- Run your full device backup (Google One or iCloud)
- Back up photos and videos through Google Photos or iCloud Photos
- Manually copy any files you downloaded that aren’t in your camera roll
- Verify each backup completed successfully with correct timestamps
- Write down or save your important passwords and Wi-Fi credentials
- Now reset
After the Reset: Restoring Your Data
Restoration is usually straightforward. When you set up the freshly reset phone, both Android and iPhone will ask if you want to restore from a backup during the initial setup flow. Choose your most recent backup and let it run.
Photos and app data typically restore in the background over the next hour or two — you don’t have to wait for it to finish before using the phone.
If you backed up to a computer, the restore process runs through Finder or iTunes the same way: connect the device, open the backup, and restore.
One thing to know: apps reinstall automatically during restoration, but you’ll likely need to log back into most of them. Have your passwords ready — a password manager like Bitwarden or 1Password makes this much less painful.
Don’t Skip the Backup — Even If the Reset Feels Urgent
When a phone is misbehaving badly, the temptation is to just wipe it immediately and deal with the consequences later. That’s how people lose years of photos or get locked out of their bank accounts.
Taking 30 to 60 minutes to properly backup your phone before a factory reset is always worth it. Even if the backup feels redundant because “everything’s in the cloud,” verifying that is the only way to know for sure.
Phones are replaceable. The data on them often isn’t.
