How to Back Up and Transfer Data Before Upgrading Your Phone (Without Losing Data)

How to Back Up and Transfer Data Before Upgrading Your Phone (Without Losing Data)

Upgrading your phone is exciting, but don’t let that excitement distract you from protecting what matters most your data. Photos, contacts, and messages don’t always transfer automatically, and one missed step can lead to permanent loss.

Before you make the switch, it’s essential to follow the right backup and transfer process. Below is everything you need to ensure a smooth, stress-free upgrade.

💡 Pro Tip: Always create both a cloud backup and a local backup before upgrading. This gives you a double layer of protection in case one method fails.
📌 Example:  If your iCloud backup fails due to low storage, having a local backup on your laptop ensures your photos and WhatsApp chats are still safe and ready to restore.

🛠️ Essential Preparation Steps

Step What You Need to Do Why It Matters
01 Ensure both phones are fully charged or plugged in Prevents interruptions during backup or transfer
02 Connect to a stable Wi-Fi network Avoids data corruption or incomplete transfers
03 Update your current phone to the latest software version Ensures compatibility with your new device
04 Gather necessary login credentials like your Apple ID / Google account login credentials Required to restore backups and access your data
💡 Pro Tip:  Always test your Wi-Fi speed before starting. A slow connection can turn a 10-minute transfer into an hour-long headache.

How To Back Up Your iPhone (Using iCloud)?

1
Ensure your iPhone is connected to Wi-Fi and plugged into power
2
Open Settings and tap your name at the top
3
Go to iCloud → iCloud Backup
4
Tap Back Up Now to start the backup process immediately.
5
Wait until you see "Last Backup: Just now" with a green indicator

⚠️ Important Note

iCloud syncis not equivalent to a true backup.

Sync updates data like photos, contacts, and notes but it does not include:

  • App data
  • Device settings
  • Home screen layout

While sync keeps data like photos, contacts, and notes current, a full backup captures device settings, home screen layout, and app data not covered by syncing, ensuring a complete transfer. A full backup ensures a complete and seamless transfer to your new device.

Using Local Backup: Back Up Your iPhone to a Computer:

🍏 Mac Backup (via Finder)

  1. Ensure macOS Catalina 10.15 or later is installed.
  2. Connect your iPhone to the Mac using a USB cable.
  3. Open a Finder window and select your iPhone under Locations.
  4. If prompted, tap Trust on your iPhone and enter your passcode.
  5. In the General tab, select Back up all of the data on your iPhone to this Mac.
  6. Optional: Select Encrypt local backup to secure your data and save passwords.
  7. Click Back Up Now and wait for the process to finish.
💡 Pro Tip: Always check available storage on your Mac before starting. A full iPhone backup can be tens of GBs!

🖥️ Windows Backup (via iTunes)

  1. If you don't have an Apple laptop, here’s how you can back up to Windows instead.
  2. Install/Open iTunes. Ensure you have the latest version of iTunes installed (preferably from the Apple website rather than the Microsoft Store for better reliability).
  3. Connect your iPhone to your PC using a USB cable.
  4. In the iTunes app, click the iPhone button near the top left.
  5. If prompted, tap Trust on your iPhone and enter your passcode.
  6. Click the Summary tab in the left panel.
  7. Under the "Backups" section, select This Computer and click Back Up Now.
  8. Select Encrypt local backup and set a password.
💡 Pro Tip: Close unnecessary apps during backup to speed up the process and avoid errors.

☁️ How to Back Up Your Android (Using Cloud)

For Android users, Google Drive is the default cloud backup, but there are other options, though not as integrated as Drive is. So, unless you have a personal reason, Google Drive is the best route. Your backup can be done in different ways.

🟢 Manual Backup via Google One

  1. Open your device’s Settings.
  2. Tap Google > All services > Backup.
  3. Ensure Backup by Google One is turned on.
  4. Turn on backup for photos, videos, and other device data.
  5. Tap Back up now to start an immediate manual backup.

🟠 Backup Photos & Videos via Google Photos

  1. Open the Google Photos app.
  2. Tap your profile icon > Photos settings > Backup.
  3. Toggle on Backup to start manual backup (or tap Back up now if already enabled).

🟢 Backup Files via Google Drive

  1. Open the Google Drive app.
  2. Tap the + icon > Upload.
  3. Select the files or folders you want to back up.
  4. Tap Upload to start the transfer.

Pro Insight: The advantage of this method is that you have immediate access to all your backed-up data the moment you log into your account on the new device. Also, make sure to confirm you have enough cloud storage available before you start the backup.

Local Backup for Android (Windows PC)

 
1
Connect your phone to the PC via USB cable.
2
On your phone, swipe down the notification shade. Look for "USB for charging" and tap it. Select File Transfer or MTP.
3
Open File Explorer on your PC and locate your phone under "This PC".
4
When inside your laptop, you need to look out for these three folders and copy them to your laptop:
Folder Contents
DCIM/Camera Photos & Videos
Download PDFs & Files
Music/Pictures Media Libraries
5
Simply drag the folders you want from the phone to a folder on your PC.
💡 Pro Tip: Check the copied files on your PC before disconnecting. This prevents accidental loss of photos, videos, or important documents.

Local Backup for Android (Mac)

Classic Way

Download Android File Transfer (AFT). It’s a basic, no-frills window that opens when you plug in your phone.

Modern Way (2026 Update)

Since AFT can be buggy on newer macOS versions, many users now prefer MacDroid or OpenMTP. These allow you to mount your phone so it actually looks like a disk drive in Finder, making manual backups much smoother.

💡 Pro Tip: If AFT fails on newer macOS versions, switch to MacDroid or OpenMTP for a smoother experience.

Using Samsung Smart Switch

If you own a Galaxy device or are moving to one, Samsung Smart Switch makes the backup and transfer process easier. Here's how to make the most of it:

1
PC/Mac App: Download Smart Switch for Desktop. Different from the mobile app, it’s designed specifically for full-system backups.
2
Full Backup: Click Backup Once connected, click Backup. It will automatically grab your device’s data like contacts, messages, call logs, and even your home screen layout.
3
Selective Restore: If you get a new phone later, you can click Restore and choose exactly which pieces of your old digital life you want to bring back.
4
Software Updates: A hidden perk of the desktop version is the ability to force-install system updates if your phone is being stubborn over Wi-Fi.

Key Directories to Focus On

Here are a few pro tips for you as you do your local backup. Instead of backing up the whole phone (which includes a lot of "app junk"), focus on these specific directories:

 

📸
Photos/Videos:
Internal Storage/DCIM/Camera
💬
WhatsApp Media:
Internal Storage/Android/media/com.whatsapp/WhatsApp/media
📄
Documents:
Internal Storage/Documents
⬇️
Downloads:
/Internal Storage/Download
💡 Pro Tip: Focus only on these important directories to avoid backing up unnecessary "app junk," which saves time and storage space.

App-Specific Backups

You are almost there, just a little more to ensure no data is left behind. Certain apps require a separate backup inside the app itself.

For apps like these, you will need to back them up in the app. Even if you have done the local or cloud backup, these things won't automatically come back when setting up your phone.

🤖

Android (Google Drive)

  1. Open WhatsApp > Tap three dots (Top Right) > Settings.
  2. Navigate to Chats > Chat backup.
  3. Tap Google Account to select your email.
  4. Tap Back Up. Ensure "Include videos" is toggled on if needed.
🍏

iPhone (iCloud)

  1. Go to iPhone Settings > [Your Name] > iCloud > iCloud Drive (Ensure it is On).
  2. Open WhatsApp > Settings > Chats > Chat Backup.
  3. Tap Back Up Now.

FAQs

How do I back up data before transferring to a new phone?
Complete your cloud and local backups first, then back up any app-specific data like WhatsApp separately. Only start the transfer once you've confirmed everything is backed up.
What should I back up before changing phones?
Prioritize contacts, photos, videos, messages, WhatsApp chats, two-factor authentication apps, and any important documents or files.
How do I transfer everything from my old phone to my new phone?
iPhone users can use Quick Start wirelessly or via a USB cable. Android users can use a USB-C cable during setup or Smart Switch if moving to a Samsung. If switching between platforms, use Move to iOS (Android to iPhone) or Google Drive (iPhone to Android).
Do I need to back up my iPhone before upgrading?
Yes. While Quick Start transfers most data directly, having a fresh iCloud or local backup beforehand ensures nothing is lost if something goes wrong during the transfer.
Is Android backup automatic?
Partially. Google One can back up automatically in the background, but it's best to trigger a manual backup before upgrading to make sure everything is current before you switch.

You risk permanently losing photos, messages, contacts, app data, and WhatsApp chats. Some data may be partially recoverable, but most of it won't be.

It depends. If your photos are backed up to Google Photos, deleting them from your phone won't automatically remove them from Google Photos. However, if you delete them from Google Photos directly, they will be removed from all synced devices.
