Part 2. Other Ways to Clear Storage on iPhone

Your iPhone is running low on storage, but most of the time, you don’t know how much data it accumulates. Unless you don’t bother getting a monthly subscription to iCloud, you can expand the iCloud storage space to keep app data, photos, music, video clips, and so on. However, this is not always the case. Rather than keeping unused apps and piled files that can harm your device, you can free up more space on the iPhone. And before cleaning up the iPhone, following is how to check storage on iPhone and other cleaning steps you need.

Step 1:
Go to the settings app and locate the General menu. Choose the iPhone Storage option.
Step 2:
From the top part, it gives the overall capacity and how apps, media, photos, mail, and other files consume the space.

Now, what is the best way to clear up more space on the iPhone instead of expanding iCloud? This part will show different methods to keep your files in order and prevent them from overloading the storage space. Stick around and see the best solution for you.

Offload Apps or Delete Unused Apps

Downloaded applications significantly impact your device, as you can see from iPhone Storage details. You have installed dating apps or downloaded videos from streaming services. You can uninstall the non-essential apps, but alternatively, use the Offload Apps option if you don't want to remove Netflix or other important apps. It helps to clear and free up space on the iPhone while keeping the app data. See the following steps to use the function:

Step 1:
From the settings app, go directly to the General menu and tap the iPhone Storage option. Wait until all applications are loaded on the screen.
Step 2:
Choose one app that has a large file size. Then, tap the Offload App button. This option will uninstall the selected app, but you can reinstall it, and the app data will be there.

Step 3:
If you don’t use an app too much, choose the Delete App option. This will remove the application from the device, along with all of the data.

Optimize iPhone Photos and Videos

As you may know, the Camera app produces high-quality images and footage that are excellent for professional photoshoots or filmmaking. But it can take too much space, especially when you don’t delete the extra or failed shots. Aside from deleting duplicated and repetitive shots, the iPhone gives a function to optimize captured images without lowering the quality. Here’s how you can activate it:

Step 1:
Launch the Settings app and choose the Camera option. Head to the Formats menu.
Step 2:
Tap the High Efficiency option to reduce the file size of each captured media. The photos will be saved as HEIF files, while videos will be in HEVC.

Step 3:
Ensure the checkmark is on the chosen option. Note that these formats are supported across Apple devices but unsupported by most programs and other operating systems.
Step 4:
Additionally, you must turn off the Live Photos feature as it turns photos into a short video. Open the Camera app and tap the icon from the upper right corner. You may see Live Photos as one, but they will be saved on iCloud as two files: a photo and a video.

Erase Cache from Safari

Your browser will keep data from the sites you visit frequently. That includes cache, cookies, and history. The cache is one of the most storage-consuming files, and you may not see the difference, but it can also slow the browsing speed once piled into a larger file. But when you use this option, it will log you out from websites and clear the search history. If that is okay with you, follow these steps:

Step 1:
Choose the Safari menu from the settings app. Press the Clear History and Website Data button.
Step 2:
A popup will appear at the bottom part of the screen. Confirm the action by tapping the Clear History and Data button.

Step 4:
Tap the Clear Browsing Data button to delete all history, cache, and cookies. You can select optionally if you want to keep other websites.

Free Up Space from the Messages App

Messages only take up a small portion of your storage space, but it will be a problem if you haven’t deleted any conversation with images attached. The common way to delete texts is to individually delete them from the Messages app, but you can easily erase the older texts from the Settings app. Here’s what to do:

Step 1:
Once you are on the Settings app, find the Messages menu. Choose the Keep Messages option.
Step 2:
Select 30 Days or 1 Year. When you choose one of these options, a prompt will appear. Tap the Delete button to delete messages.

Part 3. FAQs about Clean iPhone Storage

Why is my iPhone storage so full?

Storage space is consumed when you download apps, photos, videos, documents, and so on. Most apps also store data when you browse within them or download movies in high resolution. You can always keep track of the space from the settings app on your iPhone.

Does deleting Photos free up storage?

Definitely, yes. The camera app captures high-quality pictures and videos, which will eventually take up more device space when accumulated over time. Back up your photos and video clips on iCloud, then delete them to save storage space.

Why is my storage still full after deleting everything?

If the storage space did not restore after deleting files, try restarting it. Sometimes, the phone cannot quickly process the changes, so it may need a reboot to reflect the free-up space.

Which apps take more storage space on iPhone?

Apps that use more space are Instagram, Google Photos, Spotify, Gmail, mobile games, and dating apps. Most apps' space consumption ranges from 550MB to 1.65GB, so better manage them before you get low storage space.

How do you clean the iPhone space completely?

Use the Reset option, but before that, backup the data on iCloud. From the settings, tap the General menu, then choose the Transfer or Reset iPhone option. Press the Erase All Content and Settings button. Enter credentials when asked.
