How-to How to Clear Message/iMessage Cache on iPhone & iPad And Reclaim Lots...
We get a lot of queries very often regarding the huge “Other” data stored on your iPhone or iPad. Users want to know what this “Other” data is and why it’s occupying so much space. And of course, how to get rid of it.
If you are message a lot and rely on texts and iMessage for a lot of your communication, there’s a strong chance that part of the “Other” data is made up of message cache. It’s surprising how many MBs (and sometimes even GBs) are used up by the pictures, videos and other media you send via iMessage.

Follow these steps:
Obviously, it doesn’t end here. If you have an iCloud backup already, you might have to flush that too. Go to Settings → iCloud → Storage & Backup and clear out any backup that exists. You can create a new backup.
