How to turn off message optimization in Storage recommendation in IOS 13?

Hi Techdoc52,

Thanks for reaching out in Apple Support Communities. It sounds like you'd like to disable the feature that optimizes storage for Messages on your iPhone. I can see why you'd reach out about this; I'd like to help. If you're referring to the feature that automatically removes messages and attachments that were received a year or more ago, you'll need to adjust how messages are stored. Tap Settings > Messages, scroll to Message History and tap Keep Messages; from here you can select "Forever" which will disable the optimizing feature. You can also use the following resource for a few more details regarding storage optimization options: How to check the storage on your iPhone, iPad, and iPod touch

If you're referring to something different regarding storage optimization, can you let me know the exact text of the recommendation you're seeing that you'd like to disable?

Best Regards.
