How to Free up Space on Your iPhone and Android Phone

With all of the photos and videos we take, many of us run out of space. And, it usually happens at the worst possible time — baby's first steps, a celebrity sighting, hilarious pet antics. So, follow our simple steps to ensure you always have room for that next important shot.

1. Back up your phone to the cloud

If you don’t have the time or patience to sift through old photos and videos or if you want to keep all your media files, back them up to a cloud storage service and delete those you don't want locally on your phone. With cloud storage services, like Dropbox, you can choose to have your photos automatically backed up whenever you have access to WiFi, so you can have a full-resolution copy.

If you use an iPhone, the process is automatic if you've enabled the iCloud automatic backup service.

1. Open Settings.
2. Select "Apple ID."
3. Select "iCloud." Toggle on all of the apps you want to backup to iCloud. If you want your photos and video backed up, select "Photos" and toggle on "iCloud Photos." However, once you turn on iCloud Photos, any action you take on your phone will be replicated in iCloud. So if you delete a photo or video, it will delete in your iCloud backup. If you want to delete photos on your phone, we recommend backing up your phone locally as outlined below.
4. Select "iCloud Backup."
5. Toggle on "iCloud Backup." If you already have iCloud backup on, you'll see the last time you backed up to iCloud. If you're short on iCloud storage, go to Settings > Apple ID > iCloud and select "Manage Storage." There you can select "Backups." If you have old phone backups you don't need, you can delete those to regain space. You should always leave one backup for your iPhone.

If you choose to back up your photos and videos to iCloud, go to Settings > Apple ID > iCloud > Photos and toggle on iCloud Photos. Then select Optimize iPhone Storage. This keeps a lower resolution version of your photos on your phone and full resolution in iCloud. If you're traveling and on a limited data plan, go to Settings > Photos > Cellular Data and toggle off "Cellular Data" to ensure you don't go over your data plan.

For Android, you can automatically back up your phone to Google One.

1. Open Settings.
2. Select "Google." If you're concerned about mobile data, scroll down and make sure "Back up using mobile or metered Wi-Fi data" is toggled off.
3. Select "Backup." If you have backed up your phone before, you will see a list of what's backed up. If everything is backed up or if this is the first time you're backing up to Google, proceed to the next step. If you don't see everything being backed up, open the Google One app and select "Storage." Then select "View details." Now you can select "Manage backup" to select the data you want backed up.
4. Select "Back up now." If this is your first backup, you will be able to select what you want backed up.

For Android and iPhone users, consider Google Photos (for iOS and Android) which can be set up to automatically backup photos and videos over WiFi. To keep full-resolution photos, make sure you select Original as the image quality. Go to Settings > Back up & Sync > Upload size > and select Original. Google Photos also has a Free Up Space feature that deletes photos you've already back up to the cloud. For iPhones, you'll need to also delete them from the Photos app (the Apple Photos app). To do that, go to the Photos app and select 'Recently Deleted" and delete them again.

2. Back up your phone locally

To avoid the cost and limitations of cloud storage, back up your files to your computer. Of course, the downside is that you can only do this when you have access to your computer through a wired or wireless connection.

If you own an iPhone and a Mac running MacOS 10.15 or later, you can use the Finder app to backup your iPhone. Open the Finder app and then select General > Back up all of the data on your iPhone to this Mac. You can then choose the option to encrypt your backup data with a password by selecting "Encrypt local backup." (For earlier versions of MacOS, you can use iTunes. Follow Apple's instructions here.) If you're interested in backing up just your photos and videos to your computer, check out our step-by-step guide to how to download iPhone photos to a computer. You can also use AirDrop to transfer files without having to connect your phone to your computer via USB cable. If you use a Windows PC, you can use iTunes for Windows. Open iTunes, click on the Device button in the top menu bar, select "Summary," and then click on "Back Up Now."

If you use an Android device, connect your phone to your computer via a USB cable. Your Windows computer should detect your phone as a mass storage or media storage device, and you will be able to drag and drop your photos, videos, and other files from your phone to a folder on your PC. If you have a Mac, install the free Android File Transfer app on your Mac and then you can drag and drop files onto your Mac.

3. Delete photos, videos and other large files

While it's great to be able to see photos and videos in your messaging app, often you don't need to keep them long term. It's easy to find and delete these old files.

For iPhone, go to Settings > General > iPhone Storage > Messages. There you in the "Photos," "Videos," "GIFs and Stickers," and "Other" folders, you can delete attachments you've sent or received. For other files, go to the Files app and select "On My iPhone." In the "On My iPhone" folder, you'll folders for all of the app that save files to the Files app. Look through the files in the folders for large files. You'll see the size of each file below the file name. Delete those files you don't need by pressing and holding the file name until the menu pops up and selecting "Delete."

For Android, open the My Files app (also called File Manager). You'll see a folder called 'Downloads." Open the folder and you'll find all of the files you've downloaded. Pressing and holding a file name will let you select files to delete.

4. Uninstall apps you don't use

While photos and videos are the usual storage hogs, apps (particularly games), can also consume storage space. It’s best to remove apps you don’t use often.

On the iPhone, go into Settings > General > iPhone Storage. You'll see a list of apps sorted by the amount of storage space used. When you select an app, you'll have the option of deleting it or offloading it. Offloading an app will remove the app but leave the data behind, in case you want to reload the app at a future date. You can also choose to automatically offload any apps you haven't used in a while. Go to Settings > App Store and toggle on "Offload Unused Apps."

On Android, go to Google Play Store > Profile icon > Manage apps & devices > Manage. Under each app name, you'll see the amount of storage it uses. To delete an app, tap the app name and then tap "Uninstall."

5. Shoot lower resolution videos

Many of today's higher-end phones can capture videos in up to 8K resolution. These high-resolution videos are clearer and have finer detail, especially if you view them on a 4K or 8K-capable TV or monitor. But, higher resolution video takes up a lot more storage space than HD videos. If you don’t need 8K or 4K videos, set your camera to capture images at a lower resolution in order to save storage space.
