How to Free Up Storage on Your Phone
Quick tips for clearing space and decluttering your iPhone or Android smartphone
We’ve all been there. When you buy a phone, you think it has plenty of storage space. Then one day you get that dreaded pop-up warning saying you’ve just about run out. When that happens, you may not be able to squeeze in one more app or photo.
So what can you do about it? Many people cringe at the idea of deleting even a backed-up snapshot of their kids.
But there are ways to make room on an Android or Apple phone without sacrificing your favorite digital possessions. Here’s how.
Get a Look at What You’re Storing
Both Android and iOS make it easy to see exactly what’s on your phone and how much space it takes up.
On an Android phone, go to Settings > Storage
(Samsung Galaxy phone owners might find this feature under Settings > Battery and device care > Storage.) There, you’ll see exactly how much space you’re using and how much is being devoted to categories such as apps, images, and videos. Tapping on one of those categories provides more detail, such as which apps are using the most space.
Optimize Your Storage Space
Once you’ve got a good idea of what’s taking up space on your phone, there are other things you can do about it.
For a lot of people, the best plan is to start with photos and videos, and then move on to downloads and apps.
Back Up to the Cloud
This is a smart move with your laptop and other devices in addition to your phone. Google Drive, iCloud, Microsoft One Drive, Dropbox, and Box let you safely tuck away your photos and other precious files for use down the road.
Moving files to cloud backup frees up space on your devices. But it’s also a smart idea for security. While mobile ransomware attacks are rare, they do occur, and anybody can misplace or accidentally break a phone. In a case like that, you’ll be happy to have your photos stored in the cloud, too.
You can back up a lot of files free of charge. But if you need more space and don’t want to pay for extra cloud storage, you can always back up your phone to a PC, Mac, or external drive instead. Of course, if that backup device gets destroyed or locked up by ransomware, too, you may be out of luck.
Move Your Files to an SD Card
If you use an iPhone or certain Android phones, this isn’t an option. But if you have a phone with an SD card slot, feel free to be a digital pack rat and expand your available storage. Here are the instructions for Android devices with Files by Google and for Samsung Galaxy’s My Files app.
Just remember to set your phone to store your photos, videos, and music on the card, otherwise they’ll end up on the phone’s internal storage, says Richard Fisco, who oversees electronics testing at Consumer Reports.
Apps can be moved to SD cards, too, but be careful, he warns.
“Some apps you move will have their icon disappear from the home screen, though it will still appear in your app drawer,” Fisco says. “And many app widgets won’t work if you move the app to an SD card.”
Optimize Your Photos
Photo optimization on your smartphone stores full-resolution versions in the cloud while leaving smaller versions on your phone.
You might think that doing so would result in blurry or grainy images, but that’s not necessarily true, Fisco says.
He notes that high-end smartphones take pictures in much higher resolutions than their screens will support. For example, the new iPhone 13 has a 12-megapixel camera but only what amounts to a 2.96-megapixel screen. “So you don’t see all the details of the image anyway,” Fisco says. Plus, he points out that you’re looking at them on a screen that’s just about 6 inches.
On an Android phone and iPhone, head to Settings for your photos app. Google Photos has an option to “Free up space,” which will back up your photos to your Google account while freeing up space on your phone. On the iPhone, under Settings > Photos, you can enable the “Optimize iPhone storage” option.
But be at least a little picky about the photos you save. All of us take pictures that are out of focus or otherwise not good enough to use for anything. It’s a lot easier to delete these files as you go than comb through thousands of pictures later, when your phone gets full.
Clear Your Cache
On an Android phone, when you select particular apps in the “Storage” settings section, you’ll usually get the option of clearing the cache or deleting all data. Clearing the cache removes temporary files, such as search history in YouTube or Chrome. Deleting the data clears the cache as well as all other information stored in the app, such as user settings. Either of these options will free up at least a little bit of space.
On an iPhone, your best bet is clearing history and website data in the Safari browser, Fisco says. This could take up a couple of hundred megabytes of storage space, depending on your browser usage. For Safari, go to Settings > Safari > Clear History and Website Data. You can do this in other iPhone browsers, such as Chrome, too.
Delete Old Files
Some phones come with extra storage management features. Google Pixel phones, for example, have a “Smart Storage” option. When this is enabled, which you can do with a toggle switch on the Storage settings screen, the phone automatically removes backed-up photos and videos that are more than 60 days old. And when a phone’s storage is almost full, it will automatically remove all backed-up photos and videos.
If you don’t want to do that, you can manually clear out your downloads by going through your download directory, Fisco says. You’ll find this in the Files app on an Android phone or iPhone or the My Files app on Samsung Galaxy phones.
Or you can open an individual app and delete the files it downloaded. For example, I freed up about a gigabyte of space on my iPhone by deleting the downloaded songs in my Google Play Music app.
On that note, make sure to weed through all of your music libraries. In the age of streaming, you really don’t need to store a lot on your phone. That goes for podcasts, too.
It also helps to clear out your old iMessages or at least any big attachments tied to them. On the iPhone Storage screen you can click on “Review large attachments,” which will give you a list of the biggest attachments stored on your phone. Delete what you don’t need anymore.
You can also save space by changing your settings to save messages for a year or just 30 days instead of forever.
Pare Down Your Apps
As mentioned before, your phone’s storage screen will show you exactly how much storage each of your apps is using, along with the last time you used the app.
Don’t think an app is worth the space anymore? Just tap on it to delete, or off-load it instead. Off-loading deletes the app but keeps the documents and data related to it, often freeing up more than half of the space that had been taken up by the app.
And if you later decide that you want to use all the data, you can just download the app again, free, and pick up where you left off, Fisco says.
