Key Takeaways
- Back up your old phone before doing anything else — this is your safety net.
- Android and iPhone each have built-in transfer tools that handle most data automatically.
- Apps reinstall automatically, but some settings and in-app data may need manual attention.
- Switching between Android and iPhone requires extra steps for messages and some app data.
- After transferring, verify contacts, photos, and apps before wiping the old device.

Why Phone Transfers Go Wrong — and How to Avoid It
Most data loss during a phone switch isn't caused by a failed transfer — it's caused by skipping the backup step or rushing through setup screens. Understanding what moves automatically and what requires manual attention puts you in control of the process.
When you stay within the same ecosystem (iPhone to iPhone, or Android to Android), the transfer tools are mature and reliable. Contacts, photos, app layouts, and most app data move over with minimal effort. Cross-platform moves — say, from Android to iPhone — require more planning because the two operating systems store data in different formats and the migration tools have limitations.
For anyone new to smartphone ownership, our guide to smartphone ownership fundamentals covers the broader landscape of how data is stored and managed on modern devices.
What you will need
What You'll Need Before Starting
Gather the tools and information listed below before powering on your new phone. Having everything ready prevents mid-transfer interruptions that can leave your data in an incomplete state.
Google One Backup (Android)
Backs up contacts, app data, call history, and settings to your Google account for restore on a new Android device.
iCloud Backup (iPhone)
Stores a full snapshot of your iPhone — photos, messages, app data, and settings — for seamless restore on a new iPhone.
Move to iOS app (Android to iPhone)
Apple's official app for wirelessly migrating contacts, photos, messages, and bookmarks from an Android phone to a new iPhone.
Google Drive
Useful for manually backing up photos and documents, especially when switching from iPhone to Android.
USB-C or Lightning cable
Enables a faster wired connection for direct phone-to-phone transfer on supported devices.
Charge Both Phones Before You Start
A transfer can take anywhere from a few minutes to over half an hour depending on how much data you have. Make sure both phones are charged to at least 50% — or keep them plugged in throughout the process — to avoid an interruption that could corrupt your data mid-transfer.
Step-by-Step: Moving Your Data
Follow these steps in order. The setup wizard on your new phone is your primary transfer tool — don't skip past it. If you are setting up your new phone for the first time, our related guide on setting up a new smartphone the right way covers the broader setup process beyond data transfer.
Don't Wipe Your Old Phone Yet
Keep your old phone intact and accessible until you have confirmed every category of data — photos, contacts, messages, and apps — has transferred successfully to your new device. Restoring data after a factory reset is significantly harder and sometimes impossible. Only proceed with erasing or selling the old phone once you are completely satisfied. See our guide on what to do before handing off your old phone for the right order of steps.
Back up your old phone
Before touching your new device, create a fresh backup of your old one. On iPhone, go to Settings → [Your Name] → iCloud → iCloud Backup and tap Back Up Now. On Android, go to Settings → System → Backup and confirm Google Backup is turned on, then tap Back up now. Wait until the backup completes — you'll see a timestamp confirming success.
Start the setup process on your new phone
Power on your new phone. Both Android and iPhone will prompt you during initial setup to restore from a backup or transfer from an old device. Do not skip this screen — this is the easiest point to transfer everything. Select the appropriate option: Restore from iCloud Backup on iPhone, or Copy apps and data on Android.
Connect and transfer (same-ecosystem switch)
Follow the on-screen pairing instructions. iPhones can use Quick Start — hold the two phones close together and authenticate with your Apple ID. Android phones from many manufacturers support a direct cable or wireless connection during setup. Sign in to your Google account and select which data categories to restore. The transfer will run automatically; larger backups may take 20–40 minutes over Wi-Fi.
Handle cross-platform transfers (Android ↔ iPhone)
If you are switching between ecosystems, use the dedicated migration tools. Android to iPhone: Install the Move to iOS app on your Android phone before starting iPhone setup, then follow the in-app code-pairing process. iPhone to Android: Many Android manufacturers include their own migration app — check your new phone's setup wizard for this option, or use Google Drive to manually back up photos and contacts from your iPhone first.
Note that SMS text history may not transfer between platforms. Some apps — particularly those tied to one operating system — will need to be reinstalled and re-configured manually.
Verify your data on the new phone
Once the transfer completes, check each category carefully: open your Contacts app and scroll through, open Photos and verify recent images are present, confirm your Messages history is there, and check that apps have been reinstalled (they may still be downloading in the background). Log back in to any app that requires a separate password — transfers don't carry stored passwords for security reasons.
Re-authenticate apps and review settings
Many apps — banking, streaming, social media — require you to log in again on a new device as a security measure. Work through these one by one. Also revisit your notification preferences, accessibility settings, and Wi-Fi passwords, as these may not restore perfectly. Once you are satisfied everything is in order, your new phone is ready for daily use.
After the Transfer: What to Double-Check
A completed transfer isn't always a perfect one. Spend a few minutes confirming the following before you put your old phone away:
- Photos and videos: Check your most recent images and a few older albums to confirm nothing is missing.
- Contacts: Search for a few key people by name to verify the records transferred cleanly.
- Apps: Some apps may still be downloading — give it an hour before assuming anything is missing.
- Two-factor authentication: If you use an authenticator app, reconfigure it on the new phone before losing access to the old one.
- Banking and financial apps: These often require identity re-verification on a new device — expect a text or email confirmation step.
Once everything checks out, you're ready to explore. If you're reinstalling apps from scratch, our walkthrough for getting started with apps will help you find and manage them confidently. And when you're done, be sure to follow the proper steps before handing off or selling your old device.
Cross-Platform Transfers Need Extra Planning
Moving from Android to iPhone (or vice versa) is more involved than switching within the same ecosystem. SMS text history, some app data, and certain settings do not transfer automatically. Plan extra time and check which apps have cross-platform data export options before you begin.
