Messages can occupy a lot of space on your iPhone/iPad, especially if you text a lot. Also, these days, with iMessage, a lot of media gets sent. All that eats up a ton of stuff from your iDevice storage.
Also, there's no way to delete all the Messages at once (unless you do a clean wipe of your iPhone). You can only delete individual conversations/threads. So Apple decided to put an auto-delete feature to Messages in iOS 8. And here we are, talking about how to auto-delete messages on your iPhone/iPad running iOS 8.

Here's how to auto-delete old Messages on your iPhone and iPad running iOS 8:
- Open Settings.
- Scroll down, tap on Messages.
- Under the label that says Message History, tap on Keep Messages.
- You have three options: Forever (doesn't delete message ever, it's the default); 30 days; 1 year.
- Pick an option from 30 days and 1 year. Usually, 30 days is good enough if you don't really look back to conversations that are older than a month. Pick 1 year, if you want to set it up like auto-manage so every year, your iPhone is purged off the messages and you have – suddenly – a ton of free space.
- That's about it. Quit the settings app and you're done.
As you can see, there are only few options in the auto-delete feature. But the options are mostly enough. Ideally, you don't want to delete messages that are 7-days old (you might want to reference them back). Also, if you really want to delete conversations, you still have the option of deleting them from the Messages interface.
Unlike this auto-delete, the expiration of audio and videos sent/received in message can take place in 2 minutes. But of course, that's an altogether different thing.
