Phone FixHow to back up your phone
A phone can be replaced in a day. The photos, chats and contacts on it cannot. Ten minutes of setting up backup protects them for good.
What needs backing up
| What | Where it usually lives | How it is kept safe |
|---|---|---|
| Contacts, calendar | Your Google or Apple account, if saved there | Synced automatically. Contacts saved "to phone" or "to SIM" are not |
| Photos and videos | The phone | Google Photos or iCloud Photos backup, or copied to a computer |
| WhatsApp chats | The phone | WhatsApp's own backup to Google Drive or iCloud |
| Other apps' data | Varies | The system backup covers some; accounts cover the rest |
| Files and downloads | The phone | Copied to a computer, drive or cloud |
| Authenticator codes, banking apps | The phone | Must be moved or re-registered app by app. Check before erasing |
Android
1. System backup (Google One backup). Settings › System › Backup (Samsung: Settings › Accounts and backup › Back up data under Google Drive). Turn on Backup by Google One, check each line (apps, SMS, call history, device settings), and tap Back up now on Wi-Fi. The screen shows when the last backup ran.
2. Photos. Google Photos › your picture › Photos settings › Backup on. Choose the folders to include (WhatsApp images, screenshots) under "Back up device folders". Storage is shared with Gmail and Drive and is free only up to a limit; wait for "Backup complete".
3. Contacts. Contacts app › Organise (or Fix & manage) › Settings › Google Contacts sync settings › also back up and sync device contacts. To move contacts stuck on the phone or SIM: Contacts › Fix & manage › Import from SIM, or Export to file.
4. Samsung extras. Samsung account backup (Settings › Accounts and backup › Samsung Cloud) covers Samsung apps' data. Smart Switch on a computer or USB drive makes a full local copy.
iPhone
1. iCloud Backup. Settings › your name › iCloud › iCloud Backup on › Back Up Now, on Wi-Fi and power. The time of the last successful backup is shown. Free iCloud storage is small; a full phone needs a paid plan or a computer backup instead.
2. Photos. Settings › your name › iCloud › Photos › Sync this iPhone. Or use Google Photos on the iPhone.
3. Backup to a computer. Connect by cable. On a Mac open Finder; on Windows the Apple Devices app or iTunes. Select the iPhone › Back Up Now. Tick Encrypt local backup and set a password you will not forget: only encrypted backups include saved passwords, Health data and Wi-Fi settings.
4. Contacts and more. Settings › your name › iCloud › Show All: turn on Contacts, Calendars, Notes, Messages, Passwords and Keychain.
WhatsApp (both)
WhatsApp › Settings › Chats › Chat backup › Back up. Set a schedule (daily or weekly), choose whether to include videos, and consider End-to-end encrypted backup, keeping its password safe. On Android the backup goes to your Google account, on iPhone to iCloud. Note the phone number and account used: restoring needs the same number and the same Google or Apple account.
Moving between Android and iPhone: WhatsApp has an official transfer path (Settings › Chats › Transfer chats, or during set-up of the new phone); a cloud backup made on one system cannot be restored on the other.
Copy photos and files to a computer
- Android: connect by USB, pull down the notification, choose File transfer. The phone appears in File Explorer; copy the DCIM (camera), Pictures, Download and WhatsApp media folders (under Android › media › com.whatsapp).
- iPhone: connect, tap Trust. On Windows, the Photos app › Import, or File Explorer › Apple iPhone › Internal Storage › DCIM. On a Mac, the Photos or Image Capture app.
A phone-ready pen drive (USB-C or Lightning) works without a computer.
Before a reset, repair or sale: the checklist
- System backup run today, and shows as complete.
- Photos: open the photo backup on another device or the web and check that the newest picture is there.
- WhatsApp backed up, date checked.
- Authenticator apps: export or transfer accounts, or have backup codes. Losing these can lock you out of accounts.
- Banking and UPI apps: you will register again on the new or reset phone with your SIM and card or PIN.
- Know your Google or Apple account password, and the phone's screen lock.
- Note the apps you use that keep data only on the phone (some note, game and document apps), and export from each.
Check that a backup really works
Sign in to the account on the web: photos.google.com or icloud.com for photos, contacts.google.com or icloud.com for contacts. Seeing your recent items there is the proof. A backup switch that is "on" but has been failing for months, because storage was full or Wi-Fi was never available on charge, is a common and sad discovery.
Is Google or iCloud backup free?
Up to a storage limit that most photo libraries exceed in time. Beyond it you pay monthly, or keep photos on a computer or drive instead.
Does the backup include my apps?
It records which apps you had and some of their data, and downloads them again on restore. Apps that keep data only in their own account simply need you to sign in.
How often should I back up?
Leave automatic backup on, so it runs nightly on Wi-Fi and charge. Run one by hand before any repair, reset or journey.
