To clear phone storage, delete apps you no longer use, move photos and videos to cloud storage, and clear your browser and app cache. On both Android and iPhone, these three steps can recover several gigabytes in minutes. Check your storage every few weeks to keep the "Storage Full" notification from coming back.

Phone storage is divided into system files, app data, and personal media, and each category fills up faster than most people expect. High-resolution photos, background app data, and downloaded attachments are among the biggest offenders.

The good news: with a few simple habits, like using built-in optimization tools, offloading media to the cloud, and doing a quick storage check every few weeks, you can keep your device running smoothly and avoid the dreaded "Storage Full" notification altogether.

Essential to clear smartphone storage space on Android or iPhone

Understanding phone storage

Your phone's storage is divided into three main categories:

  • System storage: Used by the operating system and pre-installed apps.
  • App storage: Includes downloaded apps along with their data and cache.
  • Personal data: Photos, videos, music, and documents.

Managing these categories is essential for maintaining a clean phone and ensuring you have enough free storage space.

What’s taking up your phone storage?

There are many culprits that act as data vampires, draining the speed and the storage from your phone. Here are some of the likely ‘data vampires’ and the quick fixes to ward them off.

Storage Vampire CulpritWhat It Includes (How It Drains Storage)Quick Fix
Photos and videosCamera roll, screenshots, downloaded mediaSave your photos and videos to the cloud
App data and cacheTemporary files, web browsing/history and any saved sessionsClear your web history regularly
Messaging attachmentsAny pictures, images or other media that are sent in chat or text messagesDon't use auto-save, which retains images and attachments. Delete old chat/text threads
DownloadsAll the files you download from the web or your email; these typically include large PDFsSweep through your download folder regularly; if you don't need it, delete it

Why phone storage Fills up

Apps store data as you use them, and heavy-use apps like TikTok, YouTube and app-based games (like Call of Duty: Mobile or Wuthering Waves) can quickly consume space. High-resolution photos, videos, and media sent through text messages also add up over time, often without you realizing it. By regularly managing your mobile phone’s storage, you can avoid running out of space when you need it most.

Tips for clearing phone storage

Here are straightforward steps to help you free up storage and keep your phone running smoothly, based on phone type (iPhone and Android)

How to clear iPhone storage

If you’re trying to free up space on your iPhone, the process to delete apps, transfer photos, and clear your cache is incredibly simple.

1. Remove apps you don’t want

Evaluate all the apps on your iPhone and remove any apps you no longer use or want. The process involves holding the icon of the app until you see all the apps wiggling. Now tap the app(s) you want to remove. If you remove something you didn’t intend to delete, you can always add it back to your screen via the App Store (your purchases are saved).

2. Transfer photos to the cloud

If you have access to Apple’s cloud service, transfer all your photos and videos to the cloud to free up space on your phone. You can set auto backups; click on Settings, scroll down to iCloud, then select your saving options via the iCloud. If your storage is full, you’ll need to upgrade.

3. Clear your web history browser cache.

Your iPhone stores all your web history, which can extend to months. Stop saving the data you don’t need and clear your cache. To do this, open Safari and click on the three dots (...) on the bottom right-hand corner of your web browser page. Next, click Bookmarks; you will see three icons: an open book, a pair of reading glasses, and a clock. Tap the clock. Click the three dots on the top right hand of the page (...) and select Clear (it will be in red). This allows you to clear your web history.

4. Clear your history and website data.

You can also clean up more of your data by tapping your Settings app, scrolling down to the Apps section near the bottom of the page, and then choosing Safari. After tapping Safari under the Apps option, scroll down to find the section History and Website Data. This will include an option to Clear History and Website Data. Choose this and you can clear out more data.

5. Manage downloads and larger files.

Most newer iPhones give you the option on how long you want to save downloads and where you want to store all downloads. Once again, tap the Settings app, scroll down to the Apps section and choose Safari. In Safari’s main page, you need to scroll down to the section labeled General. This includes an option for Downloads. Click Downloads to see a screen with storing downloads and options for removing all downloads.

Free up space on Android phones

Using an Android phone? Follow these steps to free up space on your Android.

1. Evaluate and delete unnecessary apps

Delete apps you rarely use, and don’t worry—most can be reinstalled later if needed. Removing large or unused apps is one of the fastest ways to reclaim space. On an Android Device: Check Settings > Storage > Apps for a similar breakdown.

2. Transfer photos and videos to cloud storage

Use cloud services like Google Photos to back up your media and free up space. Offloading photos and videos from your device will reduce clutter and ensure your memories are securely stored.

3. Clear cache and temporary files

Clearing cached data removes temporary files that take up space but aren’t essential. This is a quick and effective way to free up storage. On an Android device: Go to Settings > Storage, select specific apps, and clear their cache.

4. Manage downloads and large files

Check your "Downloads" folder and remove files that you no longer need. Many downloaded files and attachments go unnoticed but can take up valuable space. Use a file manager to locate and delete unnecessary files.

5. Use built-in storage optimization tools

Android has a built-in tool to help you manage storage. Use the "Free Up Space" option in Settings > Storage to identify and delete unwanted files. These tools are designed to simplify the process and help you maintain an organized, clutter-free device.
