How to Transfer Your Data to a New Phone Without Losing Important Things
Changing phones should not mean sacrificing old conversations, photos or access to essential accounts. The order in which you move them matters.
The most expensive part of a new phone can be the information left on the old one. A rushed transfer may appear successful because the home screen looks familiar, only for someone to discover that a messaging archive, an authenticator or an old photograph did not follow.
Keep the original handset charged, unlocked and connected until you have checked the replacement. If you plan to sell it, resist the temptation to erase it on the same day you take the new one out of the box.
Prepare the old phone
Update the operating system and the essential apps, then make a fresh backup. Check the storage capacity of the new device: a 128 GB phone cannot take 160 GB of local content without choices being made. Write down the accounts you use for email, app purchases and cloud storage. Know your screen lock and account passwords.
Put both phones on charge and use a reliable Wi-Fi connection. Where the setup offers a direct cable, it may be more dependable for a large library. Keep a note of SIM and eSIM activation instructions from your network operator; moving your number is sometimes a separate procedure.
Moving from Android to Android
During the new Android phone's initial setup, choose the option to copy apps and data. The screen normally explains whether to connect the devices by cable or wirelessly. Follow the manufacturer's prompts and choose the content you want transferred. Some app data is restored from your Google backup later rather than copied directly.
Do not judge success from the number of app icons. Open the apps that matter, especially messaging, banking, travel tickets and authenticator services. App developers may require you to sign in again or move account-specific information manually.
Moving from Android to iPhone
Apple offers Move to iOS during iPhone setup, with the exact transfer route depending on the Android version and supported device. Keep both devices close and powered, and follow the Transfer Your Apps & Data → From Android prompts on the new iPhone. Apple warns that if the iPhone is already fully set up, using the automated setup route may require erasing the new iPhone first.
Choose photos, contacts, messages and other supported categories when prompted. Content such as purchased apps and some saved files may need to be downloaded or transferred separately afterwards. Check official guidance for WhatsApp and any other chat service before beginning; chat-transfer methods are particularly sensitive to the direction of the switch.
Moving from iPhone to Android
The new Android phone's setup can guide you through copying information from an iPhone. Depending on the model, it may show a QR code or ask you to connect a cable. Google's instructions say to keep devices connected during transfer and turn off iMessage when moving your number from an iPhone to Android so incoming messages do not continue taking the Apple route.
Do not treat a completed progress bar as evidence that every item moved. Check old and new devices side by side while the former still contains the original information.
Treat some transfers as separate jobs. Your mobile number or eSIM may need activation by your network; bank apps often require fresh verification; and authenticator apps can have account-by-account transfer rules. Write these down before you begin, rather than trying to solve them after wiping the old handset. A transfer tool moves only the categories its manufacturer says it supports.
The five-minute audit before wiping the old phone
Open a recent photo and an older one. Search for a contact you rarely call. Check a few conversations, including their attachments. Verify that two-factor authentication still works and that you can receive a phone call and a text on the intended number. Check cloud files and notes that you use offline.
Leave the old device untouched until all of those checks pass. Only then sign out, remove SIMs where appropriate and follow the manufacturer’s factory-reset instructions. If a trade-in deadline is near, prioritise backing up missing content rather than hoping it will reappear later.
