Messages take a lot of my storage and It’s getting worse every day

Everyday it takes more and more and I keep deleting images - the “big ones”- from my massages everyday by hand but it’s getting worse! Why??

Are you aware that deleting messages simply moves them to “Recently Deleted” since the introduction of iOS 16?

Open Messages. Tap “Edit” in the upper left, then “Show Recently Deleted” from the drop-down. Choose “Delete All” on the bottom.

Hello Aselif,

We would like to see how we can help you with your storage. Which iOS version are you currently running? Go to Settings > General > About for the version. If you restart the iPhone with the steps in this link, do you see any change to your storage: Restart your iPhone - Apple Support

"How to restart your iPhone X, 11, 12, 13, or later

1. Press and hold either volume button and the side button until the power-off slider appears.

2.Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3.To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."

Cheers!

Troubleshooting iPhone Storage:

Try Removing Data from the iPhone itself...

Internal storage cannot be upgraded. It is what it is. So, the maximum internal storage capacity never increases, even if you upgraded your iCloud plan. Learn More here: What's the Difference Between Device Storage and iCloud Storage? Apple Support

So, what to do...

Use my two User Tips:

Clear Space Using my User Tips:

• How to Clear Space from your Mobile Device, and What to Clear: - User Tip. You may have too much installed, and need to clear space. So, see my user tip: 
• How to Clear "Other" in your iPhone's Storage - Use Backup - User Tip. Caches would be being used for remembrance of application use. It is essentially the same for an iPhone. You'd backup your iPhone, and then restore your iPhone from the backup you've just created. "System Data" is what "Other" is called in more recent iOS versions.

Export these Messages:

You’d have to either (A.) trash them all, or (B.)export them first, so that nothing is lost. Perform my user tip, when it comes to exporting: How to Save or Print a Complete iPhone Messages Thread - Apple Community
