Find Out Why Messages Uses So Much Storage on Your iPhone

Some time back, a friend brought up that messages were taking up more than 5GB of storage on his iPhone. I didn’t pay much attention and thought of it as a joke. However, my view changed recently when I noticed my own iPhone’s storage creeping towards full capacity. Curious about the matter, I went to the settings section to check how I was using my iPhone’s storage. After looking at the visual breakdown of space usage on my device, I had a surprising realization. Messages, those seemingly harmless text exchanges, had secretly taken up a huge 4GB of valuable storage.

The exact question I had simply ignored suddenly became important. Intrigued by this unexpected storage issue, I began a quest to find out the reasons behind this oddly uneven use of storage. Let’s explore what I learned.

How Messages in iCloud Stores the Entire Messaging History on Apple’s Servers.

Your iPhone automatically saves and stores Messages on iCloud. If you’ve activated the Sync this iPhone option by navigating to Settings > iCloud > Show All > Messages > Sync this iPhone, your entire message history is automatically preserved on iCloud when this feature is enabled. Additionally, you can access your message history on all devices where this feature is active.

Distinction Between Actual Text Messages and the Associated Attachments in the Context of Storage Usage.

To fully understand why messages might be consuming a significant amount of storage space on your device, consider that text messages aren’t necessarily expected to occupy just a few kilobytes. Messages within the messages app encompass more than mere written text. Various attachments, such as photos, videos, MP3s, and documents, are integrated into these messages, and these attachments inherently possess larger file sizes than text alone.

Why Do Messages Occupy Substantial Space on iPhones?

The primary culprits for this storage consumption are attachments like photos, GIFs, videos, stickers, and files. These elements gradually accumulate and occupy storage space, often escaping our immediate notice if we’re not closely monitoring our messaging app’s usage. Threads of messages in the messages app can persist over several months, amassing hundreds of messages along the way. Due to their content richness, these threads tend to be weightier than shorter, text-only messages, thereby contributing to the consumption of iPhone storage space.

Why Are Messages Taking up So Much Storage on iCloud?

Your Messages app is taking up so much space because loads of attachments, message threads, and spam messages have been synced with iCloud. This shouldn’t surprise you, especially if you have toggled on sync this iPhone for your messages in your Settings app.

Does Deleting Text Messages Free up Space on iPhone? 

If Messages are consuming a significant amount of space, pictures attached to messages may be the primary reason. Deleting only text chats might not yield substantial results.
