How to transfer everything to your new smartphone without losing data

Unboxing a new smartphone is exciting, but the thought of moving everything over can be stressful. Messages, photos, apps, accounts and settings all need to come along, ideally without anything going missing.

Most modern phones offer reliable migration tools, but the process still benefits from a bit of preparation. With a clear plan, you can switch devices in under an hour and keep your old phone as a complete backup for peace of mind.

Step 1: Prepare your old phone before you start

Begin by checking that both your current and new phones are fully charged or connected to power. Transfers use a lot of battery, and the last thing you want is either device dying halfway through the process.

Next, connect both phones to stable Wi-Fi. Many transfers move data via your local network or the cloud, and a weak connection can slow things down significantly or cause errors.

On your old phone, update the operating system and key apps such as Google Play services on Android or iOS on an iPhone. Newer migration tools sometimes require recent software versions to work smoothly and support more data types.

Finally, clean up obvious clutter. Delete huge unused apps, very large downloads or duplicate videos. This reduces the transfer time and lets you start with a leaner, more manageable setup on the new device.

Step 2: Back up your data to the cloud

Even if you plan a direct phone to phone transfer, create a cloud backup first. This gives you a safety net if something goes wrong or if you accidentally skip an item during setup.

On Android, openSettings > Google > Backup(or similar, depending on manufacturer) and ensure that Backup by Google One is turned on. Check that app data, call history, SMS (on many devices), device settings and photos, if enabled, are included.

On iPhone, go toSettings > Your name > iCloud > iCloud Backup, turn it on, then tapBack Up Now. Wait until the backup finishes before touching anything else. You can check the time of the last successful backup in the same menu.

If you prefer not to use cloud storage for photos and videos, connect your old phone to a computer and copy the DCIM (or Photos) folder manually. This is slower but gives you a second, offline backup that is independent of any account.

Step 3: Choose the right transfer method for your combination

The best migration method depends on whether you are staying on the same platform or switching between Android and iPhone. Each path has tools tailored for it.

Android to Android

Most modern Android phones, especially from Samsung, Google, Xiaomi and others, support a quick transfer using a USB cable or Wi-Fi. During the new phone setup, you will see an option like “Copy apps and data” or “Bring your data from an old device.”

Use the suggested cable if possible. Wired transfers are often faster and more reliable, especially for large photo libraries. When prompted, select everything you want to move: apps, messages, call history, settings and media.

iPhone to iPhone

On recent iOS versions, Quick Start appears as soon as you place the new iPhone near the old one. A pattern animation shows up on the new device, and you scan it with the old camera to pair them.

You then choose whether to transfer data directly device to device via Wi-Fi (or cable, if you have the right adapter) or to restore from an iCloud backup. Device to device is usually faster and more complete, especially if your iCloud storage is limited.

Android to iPhone

Apple’sMove to iOSapp, available in the Google Play Store, handles most of the work. During iPhone setup, choose the option to move data from Android, then follow the on-screen steps to connect both devices over a private Wi-Fi network.

You can bring over contacts, message history (where supported), photos and videos, email accounts and some settings. Apps do not directly transfer, but the iPhone will suggest iOS versions of many of your Android apps for download.

iPhone to Android

Many Android manufacturers provide their own tools:Samsung Smart Switch,Google’s Data Transfer Tooland others. Typically you connect the two phones with a cable or via Wi-Fi and follow prompts on the new device.

These tools can copy contacts, messages, photos, calendars and some settings. Certain iOS data, like iMessage history outside SMS, can be harder to migrate completely, so treat your old iPhone as an archive if needed.

Step 4: Check what did not transfer automatically

Once the main transfer finishes, spend a few minutes checking categories that often need extra attention. This avoids surprises days later when you need something urgently.

Messaging apps like WhatsApp, Signal or Telegram usually require separate backups inside the app. For example, WhatsApp uses Google Drive on Android and iCloud on iPhone. Before the move, go into the app’s settings, run a manual backup, then restore it when you install the app on the new phone.

Authenticator and 2FA apps are critical for account security and are rarely included in automatic transfers. For each service, sign in on the new phone and add it as a new device or regenerate backup codes. Keep the old phone until you verify every important account works.

Banking apps, payment apps and some corporate tools often block direct data restoration and instead require a fresh login or identity check. Have your login details, payment cards or hardware tokens nearby when setting them up again.

Step 5: Move your SIM or set up eSIM correctly

If your phones use a physical SIM card, power them both off before moving it. This reduces the risk of network glitches or SIM detection problems. Once moved, turn the new phone on first and wait for it to join the mobile network.

For eSIM, your operator usually offers a QR code or activation code. On iPhone, you add it underSettings > Mobile Service. On Android, you find it under SIM or Network settings. Some regions and carriers also support eSIM transfer directly from old to new phone during setup.

After activation, test voice calls, mobile data and SMS. If you use messaging apps linked to your phone number, such as WhatsApp or Viber, confirm that they register correctly with the new device.

Step 6: Tidy up, secure and wipe the old phone

When you are confident that everything important works on the new smartphone, spend a few days using both devices side by side if you can. This makes it easier to spot any missing data or accounts.

Check that your new phone has a screen lock, biometric unlock, and, if you wish, features like Find My iPhone or Find My Device enabled. These provide protection if the phone is lost or stolen and make remote wipes possible.

Only after double checking photos, messages, notes, and key apps should you erase the old phone. Use the built in factory reset function from the settings menu, which securely removes personal data and signs you out of accounts.

If you plan to sell, recycle or give away the device, remove any memory card and restore it separately, and keep a note of the phone’s model and serial number. This information can be useful if any warranty or account questions appear later.

When something goes wrong during transfer

If the transfer stalls or fails, do not panic. Restart both phones, check Wi-Fi and battery levels, and try the process again. In many cases you can safely rerun the migration without duplicating data.

For partial transfers, restore from the cloud backup you created earlier. It is sometimes more reliable to do a clean start with a backup than to troubleshoot a half completed direct transfer.

Keep your old phone charged and untouched until everything on the new device has been running smoothly for at least a few days. Having that full backup in your drawer is often the best insurance against small mistakes during migration.
