Who this is for

People moving to a replacement phone

Choose a transfer route before the old phone is wiped, traded in or unavailable. Apple Support describes direct, wired, iCloud and computer-based iPhone migration options, while Google Android Help supports copying selected data during Android setup.

Phone owners repeatedly running out of space

Decide whether reducing on-device storage through a cloud library or keeping selected files on local USB storage fits how you need to access photos and videos.

Families needing shared access and a separate copy

Sharing can make family photos easier to reach, but account ownership, editing permissions and the location of an independent offline copy should be decided separately.

What to check before choosing storage

Priority What to check Your needs
Move files before replacing the phone Check whether direct transfer, wired migration, cloud restore or computer backup covers the photos and videos you need. Keep both phones powered until the transfer is checked. I want a route that works before my old handset is erased, returned or traded in.
Free space without losing access Check cloud-storage allowance, whether full files need an internet connection, and how you will keep a separate local copy if required. I need to know whether files remain on my phone, are available online only, or have been copied to another device before I delete anything.
Phone and drive compatibility Confirm the connector, data-capable cable, supported file system and power requirements. For Android USB storage, check your phone and software support; for external hard drives, confirm direct-phone support rather than assuming it. I want to be certain my exact phone can read and copy to the drive or adapter I plan to use.
Account recovery Update recovery email addresses, phone numbers and recovery contacts before changing phones. Check that account access works from another device. I need a way back into my photo library if I lose access to the old phone or forget a password.
Family sharing permissions Check who owns the account, who can view, edit or delete shared items, and whether a shared library is also the only copy. I want family members to access memories without accidentally giving everyone control over the only copy.

Common storage mistakes

  • Treating cloud sync as the only backup

    Apple Support says that edits and deletions made in iCloud Photos are reflected across connected devices. A synchronised library improves access, but it is not automatically a separate copy.

    Keep at least one separate, checked copy of important photos and videos on a computer or local storage device before deleting originals from the old phone.

    An unwanted deletion can spread through a synchronised library when there is no independent copy.

  • Buying a USB drive based only on its connector

    USB storage depends on the phone, software, cable, adapter, drive power needs and file system. A drive intended for computers is not automatically suitable for direct phone use.

    Check the exact phone model, operating-system version, connector, data-capable cable and file-system support, then copy a small test folder before depending on the setup.

    An unsuitable adapter, a reformatting step or insufficient power can prevent direct transfer.

  • Deleting phone files before checking the copy

    Cloud uploads depend on internet access, storage allowance and the correct account. Microsoft notes that camera-roll uploads and synchronisation can stop when available storage is exceeded.

    Open recent and older photos and videos from the destination service or device, confirm the account and folder, then delete only after the copy is usable.

    Removing the only accessible copy can make later recovery difficult and uncertain.

  • Ignoring account recovery and sharing permissions

    A cloud library may be inaccessible when recovery details are outdated. Shared collections can also create editing and deletion risks if permissions are not chosen deliberately.

    Update recovery methods before moving phones and review who can view, edit or delete shared photos and folders.

Relevant storage and cloud services

Apple

Apple’s iCloud Photos and iPhone transfer tools are relevant when you remain within an Apple-device setup or move from one iPhone to another.

  • Apple Support says iCloud Photos keeps originals in full resolution and updates the library across devices signed in to the same Apple Account.
  • Edits and deletions can propagate across devices, so Apple advises keeping backup copies. Direct external-drive formatting in Files is limited to USB-C iPhone models and specified formats.

Google

Google Photos and Android transfer tools suit Android users, iPhone-to-Android movers and people wanting an account-based library across device types.

  • Google says Photos backup can be accessed on devices signed in to the relevant Google Account, with up to 15 GB of included account storage.
  • Storage is shared with the Google Account, and backup is associated with one account at a time, so account selection and recovery details matter before changing phones.

Microsoft

OneDrive is relevant for households using Microsoft accounts, Windows PCs or Microsoft 365 and wanting camera-roll backup with Windows file access.

  • Microsoft says OneDrive camera backup on Android is backup rather than two-way synchronisation, so deleting a phone copy does not delete the backed-up OneDrive copy.
  • The 5 GB free allowance is shared across OneDrive files and photos, Outlook.com attachments and Microsoft 365 apps; uploads can stop when the allowance is exceeded.

Samsung

Samsung’s portable SSD range is an example of a USB-C portable SSD route for moving larger files between phones and computers.

  • Samsung states that the T7 includes USB-C-to-C and USB-C-to-A cables and supports Windows, macOS, smartphones and tablets.
  • Samsung also notes that host-device compatibility can vary and some operating systems may require reformatting.

Seagate

Seagate external hard drives are relevant for computer-centred offline archives rather than assumed direct-phone backup.

  • A hard drive can be useful for retaining a larger offline archive through a desktop or laptop computer.
  • Seagate states that its USB external drives are designed, tested and supported for desktop and laptop computers, so direct-phone limitations should be checked with the phone manufacturer.

Frequently asked questions

Should you transfer everything directly to a new phone before buying extra storage?

Usually, yes, if both phones are available and the supported transfer route covers the material you need. Apple Support describes direct, wired, iCloud and computer-backup options for a new iPhone, while Google Android Help supports copying selected data during Android setup. Check photos and videos on the new phone before erasing, returning or trading in the old one.

Can you plug any USB drive into an Android phone?

No. Files by Google supports browsing and managing connected USB storage on Android 7.0 or later, but this does not mean every phone, adapter, drive, cable, file system and power requirement will work together. Confirm support for your exact phone and test a small copy before moving the only copy of a library.

Can an iPhone use an external drive for photos and videos?

It can use storage accessories subject to model and accessory conditions. Apple says an iPhone or iPad must be unlocked before using a storage accessory. On USB-C iPhone models, Files can format a connected drive as APFS, ExFAT or MS-DOS (FAT); do not format a drive containing the only copy of your files.

Does iCloud Photos count as an independent backup?

Not on its own. Apple says that edits and deletions made on one device are reflected across devices using iCloud Photos, and it advises keeping backup copies of the library. Use iCloud Photos for synchronised access, then keep another checked copy if reducing the risk of a deletion, account or device problem matters to you.

What should you check before relying on a cloud library after changing phones?

Confirm that the full library has uploaded, that you can sign in on another device, that recovery information is current and that the available storage allowance is sufficient. Google says updated recovery information can help regain account access, while Apple offers recovery contacts for eligible Apple Account users.
