How we compared phone cloud storage
On phones, the deciding factors are background reliability, battery and data use, cross-platform support, and what happens to photos when you delete them from the phone. We also weighed privacy, since phone photos include faces, documents and location data.
Best picks for phones
iCloud+: best for iPhone
iCloud backs up the whole iPhone, not just photos, and restores a new phone in one step. Turn on Advanced Data Protection to make most data end-to-end encrypted. Read iCloud Advanced Data Protection and our guide to iCloud storage and backup costs.
Google Photos and Google One: best for Android
Built into Android with strong search and editing. Google holds the keys and uses its systems to organise photos. Read is Google Drive private for the privacy side.
Proton Drive: best private backup for any phone
Apps for both platforms back up photos end-to-end encrypted. Fewer smart features, more privacy. Proton Drive review.
pCloud: best for big libraries
Automatic uploads and lifetime plans suit people with years of photos and videos. pCloud review.
Sync.com: private and roomy
End-to-end encrypted camera upload with larger plans for the price. Sync.com review.
Photos are what fill phones. See our dedicated guide to private photo storage.
Private photo storage optionsPhone backup tips
Turn on backup over Wi-Fi only, let the first upload run overnight on a charger, and check that “free up space” features don’t delete originals you have not backed up elsewhere. Then confirm photos appear on the web.
- Allow background refresh and battery exceptions for the app.
- Back up over Wi-Fi to save mobile data.
- Check upload settings: original quality vs compressed.
- Verify on the provider’s website that photos arrived.
- Keep a second copy, such as a computer or external drive.

Mixed iPhone and Android households
If your family mixes iPhone and Android, choose a service with apps on both, such as Google Photos, Proton Drive, pCloud or OneDrive. iCloud works poorly on Android. Shared family plans keep cost down.

Frequently asked questions
What is the best cloud storage for iPhone?
iCloud+ is the most seamless for iPhone because it backs up the whole device and restores new phones easily. With Advanced Data Protection on, most data is end-to-end encrypted. Proton Drive and pCloud are good alternatives if you also use Android or Windows.
What is the best cloud storage for Android?
Google Photos and Google One are built into Android and offer the best search and integration. For privacy, Proton Drive and Sync.com back up photos with end-to-end encryption. pCloud suits large libraries and offers lifetime plans.
Does phone cloud backup use a lot of data?
It can, especially for video. Set backups to Wi-Fi only and the first upload will not touch your mobile data. After that, only new photos upload. Most apps also let you limit uploads to when the phone is charging.
If I delete a photo from my phone, is it deleted from the cloud?
With synced photo libraries like iCloud Photos and Google Photos, deleting on the phone usually deletes in the cloud too, after a trash period. Upload-only backups in some apps keep the cloud copy. Check your app’s setting before clearing your phone.
Is it safe to store private photos in the cloud?
It is safe from device loss, but standard services can technically access your photos. For private photos, use an end-to-end encrypted service such as Proton Drive or iCloud with Advanced Data Protection, and protect the account with two factor authentication.
